+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!
