+GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+  This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+  0. Additional Definitions.
+
+  As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+  "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+  An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+  A "Combined Work" is a work produced by combining or linking an
+Application with the Library.  The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+  The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+  The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+  1. Exception to Section 3 of the GNU GPL.
+
+  You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+  2. Conveying Modified Versions.
+
+  If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+   a) under this License, provided that you make a good faith effort to
+   ensure that, in the event an Application does not supply the
+   function or data, the facility still operates, and performs
+   whatever part of its purpose remains meaningful, or
+
+   b) under the GNU GPL, with none of the additional permissions of
+   this License applicable to that copy.
+
+  3. Object Code Incorporating Material from Library Header Files.
+
+  The object code form of an Application may incorporate material from
+a header file that is part of the Library.  You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+   a) Give prominent notice with each copy of the object code that the
+   Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the object code with a copy of the GNU GPL and this license
+   document.
+
+  4. Combined Works.
+
+  You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+   a) Give prominent notice with each copy of the Combined Work that
+   the Library is used in it and that the Library and its use are
+   covered by this License.
+
+   b) Accompany the Combined Work with a copy of the GNU GPL and this license
+   document.
+
+   c) For a Combined Work that displays copyright notices during
+   execution, include the copyright notice for the Library among
+   these notices, as well as a reference directing the user to the
+   copies of the GNU GPL and this license document.
+
+   d) Do one of the following:
+
+       0) Convey the Minimal Corresponding Source under the terms of this
+       License, and the Corresponding Application Code in a form
+       suitable for, and under terms that permit, the user to
+       recombine or relink the Application with a modified version of
+       the Linked Version to produce a modified Combined Work, in the
+       manner specified by section 6 of the GNU GPL for conveying
+       Corresponding Source.
+
+       1) Use a suitable shared library mechanism for linking with the
+       Library.  A suitable mechanism is one that (a) uses at run time
+       a copy of the Library already present on the user's computer
+       system, and (b) will operate properly with a modified version
+       of the Library that is interface-compatible with the Linked
+       Version.
+
+   e) Provide Installation Information, but only if you would otherwise
+   be required to provide such information under section 6 of the
+   GNU GPL, and only to the extent that such information is
+   necessary to install and execute a modified version of the
+   Combined Work produced by recombining or relinking the
+   Application with a modified version of the Linked Version. (If
+   you use option 4d0, the Installation Information must accompany
+   the Minimal Corresponding Source and Corresponding Application
+   Code. If you use option 4d1, you must provide the Installation
+   Information in the manner specified by section 6 of the GNU GPL
+   for conveying Corresponding Source.)
+
+  5. Combined Libraries.
+
+  You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+   a) Accompany the combined library with a copy of the same work based
+   on the Library, uncombined with any other library facilities,
+   conveyed under the terms of this License.
+
+   b) Give prominent notice with the combined library that part of it
+   is a work based on the Library, and explaining where to find the
+   accompanying uncombined form of the same work.
+
+  6. Revised Versions of the GNU Lesser General Public License.
+
+  The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+  Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+  If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+
+THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
+COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
+COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS
+AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED.
+
+BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
+TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
+BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
+CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
+CONDITIONS.
+
+1. Definitions
+
+ a. "Adaptation" means a work based upon the Work, or upon the Work and
+    other pre-existing works, such as a translation, adaptation,
+    derivative work, arrangement of music or other alterations of a
+    literary or artistic work, or phonogram or performance and includes
+    cinematographic adaptations or any other form in which the Work may be
+    recast, transformed, or adapted including in any form recognizably
+    derived from the original, except that a work that constitutes a
+    Collection will not be considered an Adaptation for the purpose of
+    this License. For the avoidance of doubt, where the Work is a musical
+    work, performance or phonogram, the synchronization of the Work in
+    timed-relation with a moving image ("synching") will be considered an
+    Adaptation for the purpose of this License.
+ b. "Collection" means a collection of literary or artistic works, such as
+    encyclopedias and anthologies, or performances, phonograms or
+    broadcasts, or other works or subject matter other than works listed
+    in Section 1(f) below, which, by reason of the selection and
+    arrangement of their contents, constitute intellectual creations, in
+    which the Work is included in its entirety in unmodified form along
+    with one or more other contributions, each constituting separate and
+    independent works in themselves, which together are assembled into a
+    collective whole. A work that constitutes a Collection will not be
+    considered an Adaptation (as defined below) for the purposes of this
+    License.
+ c. "Creative Commons Compatible License" means a license that is listed
+    at http://creativecommons.org/compatiblelicenses that has been
+    approved by Creative Commons as being essentially equivalent to this
+    License, including, at a minimum, because that license: (i) contains
+    terms that have the same purpose, meaning and effect as the License
+    Elements of this License; and, (ii) explicitly permits the relicensing
+    of adaptations of works made available under that license under this
+    License or a Creative Commons jurisdiction license with the same
+    License Elements as this License.
+ d. "Distribute" means to make available to the public the original and
+    copies of the Work or Adaptation, as appropriate, through sale or

+ f. "Licensor" means the individual, individuals, entity or entities that
+    offer(s) the Work under the terms of this License.
+ g. "Original Author" means, in the case of a literary or artistic work,
+    the individual, individuals, entity or entities who created the Work

+    musicians, dancers, and other persons who act, sing, deliver, declaim,
+    play in, interpret or otherwise perform literary or artistic works or
+    expressions of folklore; (ii) in the case of a phonogram the producer
+    being the person or legal entity who first fixes the sounds of a
+    performance or other sounds; and, (iii) in the case of broadcasts, the
+    organization that transmits the broadcast.
+ h. "Work" means the literary and/or artistic work offered under the terms
+    of this License including without limitation any production in the
+    literary, scientific and artistic domain, whatever may be the mode or
+    form of its expression including digital form, such as a book,
+    pamphlet and other writing; a lecture, address, sermon or other work
+    of the same nature; a dramatic or dramatico-musical work; a
+    choreographic work or entertainment in dumb show; a musical
+    composition with or without words; a cinematographic work to which are
+    assimilated works expressed by a process analogous to cinematography;
+    a work of drawing, painting, architecture, sculpture, engraving or
+    lithography; a photographic work to which are assimilated works
+    expressed by a process analogous to photography; a work of applied
+    art; an illustration, map, plan, sketch or three-dimensional work
+    relative to geography, topography, architecture or science; a
+    performance; a broadcast; a phonogram; a compilation of data to the
+    extent it is protected as a copyrightable work; or a work performed by
+    a variety or circus performer to the extent it is not otherwise
+    considered a literary or artistic work.
+ i. "You" means an individual or entity exercising rights under this
+    License who has not previously violated the terms of this License with
+    respect to the Work, or who has received express permission from the
+    Licensor to exercise rights under this License despite a previous
+    violation.
+ j. "Publicly Perform" means to perform public recitations of the Work and
+    to communicate to the public those public recitations, by any means or
+    process, including by wire or wireless means or public digital
+    performances; to make available to the public Works in such a way that
+    members of the public may access these Works from a place and at a
+    place individually chosen by them; to perform the Work to the public
+    by any means or process and the communication to the public of the
+    performances of the Work, including by public digital performance; to
+    broadcast and rebroadcast the Work by any means including signs,
+    sounds or images.
+ k. "Reproduce" means to make copies of the Work by any means including
+    without limitation by sound or visual recordings and the right of
+    fixation and reproducing fixations of the Work, including storage of a

+    medium.
+
+2. Fair Dealing Rights. Nothing in this License is intended to reduce,
+limit, or restrict any uses free from copyright or rights arising from
+limitations or exceptions that are provided for in connection with the
+copyright protection under copyright law or other applicable laws.
+
+3. License Grant. Subject to the terms and conditions of this License,
+Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
+perpetual (for the duration of the applicable copyright) license to
+exercise the rights in the Work as stated below:
+
+ a. to Reproduce the Work, to incorporate the Work into one or more
+    Collections, and to Reproduce the Work as incorporated in the
+    Collections;
+ b. to create and Reproduce Adaptations provided that any such Adaptation,
+    including any translation in any medium, takes reasonable steps to
+    clearly label, demarcate or otherwise identify that changes were made
+    to the original Work. For example, a translation could be marked "The
+    original work was translated from English to Spanish," or a
+    modification could indicate "The original work has been modified.";
+ c. to Distribute and Publicly Perform the Work including as incorporated
+    in Collections; and,
+ d. to Distribute and Publicly Perform Adaptations.
+ e. For the avoidance of doubt:
+
+     i. Non-waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme cannot be waived, the Licensor
+        reserves the exclusive right to collect such royalties for any
+        exercise by You of the rights granted under this License;
+    ii. Waivable Compulsory License Schemes. In those jurisdictions in
+        which the right to collect royalties through any statutory or
+        compulsory licensing scheme can be waived, the Licensor waives the
+        exclusive right to collect such royalties for any exercise by You
+        of the rights granted under this License; and,
+   iii. Voluntary License Schemes. The Licensor waives the right to
+        collect royalties, whether individually or, in the event that the
+        Licensor is a member of a collecting society that administers
+        voluntary licensing schemes, via that society, from any exercise
+        by You of the rights granted under this License.
+
+The above rights may be exercised in all media and formats whether now
+known or hereafter devised. The above rights include the right to make
+such modifications as are technically necessary to exercise the rights in
+other media and formats. Subject to Section 8(f), all rights not expressly
+granted by Licensor are hereby reserved.
+
+4. Restrictions. The license granted in Section 3 above is expressly made
+subject to and limited by the following restrictions:
+
+ a. You may Distribute or Publicly Perform the Work only under the terms
+    of this License. You must include a copy of, or the Uniform Resource
+    Identifier (URI) for, this License with every copy of the Work You
+    Distribute or Publicly Perform. You may not offer or impose any terms
+    on the Work that restrict the terms of this License or the ability of
+    the recipient of the Work to exercise the rights granted to that
+    recipient under the terms of the License. You may not sublicense the
+    Work. You must keep intact all notices that refer to this License and
+    to the disclaimer of warranties with every copy of the Work You
+    Distribute or Publicly Perform. When You Distribute or Publicly
+    Perform the Work, You may not impose any effective technological
+    measures on the Work that restrict the ability of a recipient of the
+    Work from You to exercise the rights granted to that recipient under
+    the terms of the License. This Section 4(a) applies to the Work as
+    incorporated in a Collection, but this does not require the Collection
+    apart from the Work itself to be made subject to the terms of this
+    License. If You create a Collection, upon notice from any Licensor You
+    must, to the extent practicable, remove from the Collection any credit
+    as required by Section 4(c), as requested. If You create an
+    Adaptation, upon notice from any Licensor You must, to the extent
+    practicable, remove from the Adaptation any credit as required by
+    Section 4(c), as requested.
+ b. You may Distribute or Publicly Perform an Adaptation only under the
+    terms of: (i) this License; (ii) a later version of this License with
+    the same License Elements as this License; (iii) a Creative Commons
+    jurisdiction license (either this or a later license version) that
+    contains the same License Elements as this License (e.g.,
+    Attribution-ShareAlike 3.0 US)); (iv) a Creative Commons Compatible
+    License. If you license the Adaptation under one of the licenses
+    mentioned in (iv), you must comply with the terms of that license. If
+    you license the Adaptation under the terms of any of the licenses
+    mentioned in (i), (ii) or (iii) (the "Applicable License"), you must
+    comply with the terms of the Applicable License generally and the
+    following provisions: (I) You must include a copy of, or the URI for,
+    the Applicable License with every copy of each Adaptation You
+    Distribute or Publicly Perform; (II) You may not offer or impose any
+    terms on the Adaptation that restrict the terms of the Applicable
+    License or the ability of the recipient of the Adaptation to exercise
+    the rights granted to that recipient under the terms of the Applicable
+    License; (III) You must keep intact all notices that refer to the
+    Applicable License and to the disclaimer of warranties with every copy
+    of the Work as included in the Adaptation You Distribute or Publicly
+    Perform; (IV) when You Distribute or Publicly Perform the Adaptation,
+    You may not impose any effective technological measures on the
+    Adaptation that restrict the ability of a recipient of the Adaptation
+    from You to exercise the rights granted to that recipient under the
+    terms of the Applicable License. This Section 4(b) applies to the
+    Adaptation as incorporated in a Collection, but this does not require
+    the Collection apart from the Adaptation itself to be made subject to
+    the terms of the Applicable License.
+ c. If You Distribute, or Publicly Perform the Work or any Adaptations or
+    Collections, You must, unless a request has been made pursuant to
+    Section 4(a), keep intact all copyright notices for the Work and
+    provide, reasonable to the medium or means You are utilizing: (i) the
+    name of the Original Author (or pseudonym, if applicable) if supplied,
+    and/or if the Original Author and/or Licensor designate another party
+    or parties (e.g., a sponsor institute, publishing entity, journal) for
+    attribution ("Attribution Parties") in Licensor's copyright notice,
+    terms of service or by other reasonable means, the name of such party
+    or parties; (ii) the title of the Work if supplied; (iii) to the
+    extent reasonably practicable, the URI, if any, that Licensor
+    specifies to be associated with the Work, unless such URI does not
+    refer to the copyright notice or licensing information for the Work;
+    and (iv) , consistent with Ssection 3(b), in the case of an
+    Adaptation, a credit identifying the use of the Work in the Adaptation
+    (e.g., "French translation of the Work by Original Author," or
+    "Screenplay based on original Work by Original Author"). The credit
+    required by this Section 4(c) may be implemented in any reasonable
+    manner; provided, however, that in the case of a Adaptation or
+    Collection, at a minimum such credit will appear, if a credit for all
+    contributing authors of the Adaptation or Collection appears, then as
+    part of these credits and in a manner at least as prominent as the
+    credits for the other contributing authors. For the avoidance of
+    doubt, You may only use the credit required by this Section for the
+    purpose of attribution in the manner set out above and, by exercising
+    Your rights under this License, You may not implicitly or explicitly
+    assert or imply any connection with, sponsorship or endorsement by the
+    Original Author, Licensor and/or Attribution Parties, as appropriate,
+    of You or Your use of the Work, without the separate, express prior
+    written permission of the Original Author, Licensor and/or Attribution
+    Parties.
+ d. Except as otherwise agreed in writing by the Licensor or as may be
+    otherwise permitted by applicable law, if You Reproduce, Distribute or
+    Publicly Perform the Work either by itself or as part of any
+    Adaptations or Collections, You must not distort, mutilate, modify or
+    take other derogatory action in relation to the Work which would be
+    prejudicial to the Original Author's honor or reputation. Licensor
+    agrees that in those jurisdictions (e.g. Japan), in which any exercise
+    of the right granted in Section 3(b) of this License (the right to
+    make Adaptations) would be deemed to be a distortion, mutilation,
+    modification or other derogatory action prejudicial to the Original
+    Author's honor and reputation, the Licensor will waive or not assert,
+    as appropriate, this Section, to the fullest extent permitted by the
+    applicable national law, to enable You to reasonably exercise Your
+    right under Section 3(b) of this License (right to make Adaptations)
+    but not otherwise.
+
+5. Representations, Warranties and Disclaimer
+
+UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
+OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
+KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
+INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
+FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
+LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
+WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION
+OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
+
+6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
+LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
+ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
+ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+7. Termination
+
+ a. This License and the rights granted hereunder will terminate
+    automatically upon any breach by You of the terms of this License.
+    Individuals or entities who have received Adaptations or Collections
+    from You under this License, however, will not have their licenses
+    terminated provided such individuals or entities remain in full
+    compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
+    survive any termination of this License.
+ b. Subject to the above terms and conditions, the license granted here is
+    perpetual (for the duration of the applicable copyright in the Work).
+    Notwithstanding the above, Licensor reserves the right to release the
+    Work under different license terms or to stop distributing the Work at
+    any time; provided, however that any such election will not serve to
+    withdraw this License (or any other license that has been, or is
+    required to be, granted under the terms of this License), and this
+    License will continue in full force and effect unless terminated as
+    stated above.
+
+8. Miscellaneous
+
+ a. Each time You Distribute or Publicly Perform the Work or a Collection,
+    the Licensor offers to the recipient a license to the Work on the same
+    terms and conditions as the license granted to You under this License.
+ b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
+    offers to the recipient a license to the original Work on the same
+    terms and conditions as the license granted to You under this License.
+ c. If any provision of this License is invalid or unenforceable under
+    applicable law, it shall not affect the validity or enforceability of
+    the remainder of the terms of this License, and without further action
+    by the parties to this agreement, such provision shall be reformed to
+    the minimum extent necessary to make such provision valid and
+    enforceable.
+ d. No term or provision of this License shall be deemed waived and no
+    breach consented to unless such waiver or consent shall be in writing
+    and signed by the party to be charged with such waiver or consent.
+ e. This License constitutes the entire agreement between the parties with
+    respect to the Work licensed here. There are no understandings,
+    agreements or representations with respect to the Work not specified
+    here. Licensor shall not be bound by any additional provisions that
+    may appear in any communication from You. This License may not be
+    modified without the mutual written agreement of the Licensor and You.
+ f. The rights granted under, and the subject matter referenced, in this
+    License were drafted utilizing the terminology of the Berne Convention
+    for the Protection of Literary and Artistic Works (as amended on
+    September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
+    Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996
+    and the Universal Copyright Convention (as revised on July 24, 1971).
+    These rights and subject matter take effect in the relevant
+    jurisdiction in which the License terms are sought to be enforced
+    according to the corresponding provisions of the implementation of
+    those treaty provisions in the applicable national law. If the
+    standard suite of rights granted under applicable copyright law
+    includes additional rights not granted under this License, such
+    additional rights are deemed to be included in the License; this
+    License is not intended to restrict the license of any rights under
+    applicable law.
+

+    Creative Commons is not a party to this License, and makes no warranty
+    whatsoever in connection with the Work. Creative Commons will not be
+    liable to You or any party on any legal theory for any damages

+    Commons has expressly identified itself as the Licensor hereunder, it

+MESECONS by Jeija and contributors
+
+Mezzee-what?
+------------
+[Mesecons](http://mesecons.net/)! They're yellow, they're conductive, and they'll add a whole new dimension to Minetest's gameplay.
+
+Mesecons is a mod for [Minetest](http://minetest.net/) that implements a ton of items related to digital circuitry, such as wires, buttons, lights, and even programmable controllers. Among other things, there are also pistons, solar panels, pressure plates, and note blocks.
+
+Mesecons has a similar goal to Redstone in Minecraft, but works in its own way, with different rules and mechanics.
+
+OK, I want in.
+--------------
+Go get it!
+
+[DOWNLOADS PAGE](http://mesecons.net/downloads.php)
+
+Now go ahead and install it like any other Minetest mod. Don't know how? Check out [the wonderful page about it](http://wiki.minetest.com/wiki/Mods) over at the Minetest Wiki. For your convenience, here's a quick summary:
+
+1. If Mesecons is still in a ZIP file, extract the folder inside to somewhere on the computer.
+2. Make sure that when you open the folder, you can directly find `README.md` in the listing. If you just see another folder, move that folder up one level and delete the old one.
+3. Open up the Minetest mods folder - usually `/mods/`. If you see the `minetest` or folder inside of that, that is your mod folder instead.
+4. Copy the Mesecons folder into the mods folder.
+
+Don't like some parts of Mesecons? Open up the Mesecons folder and delete the subfolder containing the mod you don't want. If you didn't want movestones, for example, all you have to do is delete the `mesecons_movestones` folder and they will no longer be available.
+
+There are no dependencies - it will work right after installing!
+
+How do I use this thing?
+------------------------
+How about a [quick overview video](https://www.youtube.com/watch?v=6kmeQj6iW5k)?
+
+Or maybe a [comprehensive reference](http://mesecons.net/items.php) is your style?
+
+An overview for the very newest of new beginners? How does [this one](http://uberi.mesecons.net/projects/MeseconsBasics/index.html) look?
+
+Want to get more into building? Why not check out the [Mesecons Laboratory](http://uberi.mesecons.net/), a website dedicated to advanced Mesecons builders?
+
+Want to contribute to Mesecons itself? Check out the [source code](https://github.com/Jeija/minetest-mod-mesecons)!
+
+Who wrote it anyways?
+---------------------
+These awesome people made Mesecons possible!
