 # Schematic Editor [`schemedit`]
 
 ## Version
-1.1.0
+1.3.0
 
 ## Description
 This is a mod which allows you to edit and export schematics (`.mts` files).
 
-It supports node porbabilities, forced node placement and slice probabilities.
+This mod works in Minetest 5.0.0 or later, but recommended is version 5.1.0
+or later.
+
+It supports node probabilities, forced node placement and slice probabilities.
 
 It adds 3 items:
 
-* Schematic Creator: Used to mark a region and export it as schematic
+* Schematic Creator: Used to mark a region and export or import it as schematic
 * Schematic Void: Marks a position in a schematic which should not replace anything when placed as a schematic
 * Schematic Node Probability Tool: Set per-node probabilities and forced node placement
 
-It also adds the server command `placeschem` to place a schematic.
+Note: The import feature requires Minetest 5.1.0 or later.
+
+It also adds these server commands:
+
+* `placeschem` to place a schematic
+* `mts2lua` to convert .mts files to .lua files (Lua code)
+
+There's also a setting `schemedit_export_lua` to enable automatic export to .lua files.
 
 ## Usage help
 Usage help can be found when you use the optional Help modpack (mods `doc` and `doc_items`).
+The “server” privilege is required for most features.
 
 You should also refer to the Minetest Lua API documentation to understand more about schematics.

 The schematic creator is used to save a region of the world into a schematic file (.mts).=Der Schematic-Macher wird benutzt, um eine Region der Welt in eine Schematic-Datei (.mts) zu speichern.
 To get started, place the block facing directly in front of any bottom left corner of the structure you want to save. This block can only be accessed by the placer or by anyone with the “schematic_override” privilege.=Um anzufangen, platzieren Sie den Block direkt vor einer beliebigen unteren linken Ecke des Gebäudes, das Sie speichern möchten. Dieser Block kann nur vom Platzierer oder von Spielern mit dem „schematic_override“-Privileg benutzt werden.
 To save a region, use the block, enter the size and a schematic name and hit “Export schematic”. The file will always be saved in the world directory. Note you can use this name in the /placeschem command to place the schematic again.=Um eine Region zu speichern, benutzen Sie den Block, geben Sie die Größe und einen Schematic-Namen ein und klicken Sie auf „Schematic exportieren“. Die Datei wird immer im Weltverzeichnis gespeichert. Beachten Sie, dass Sie diesen Namen im „/placeschem“-Befehl benutzen können, um das Schematic erneut zu platzieren.

 Y slices are used to remove entire slices based on chance. For each slice of the schematic region along the Y axis, you can specify that it occurs only with a certain chance. In the Y slice tab, you have to specify the Y slice height (0 @= bottom) and a probability from 0 to 255 (255 is for 100%). By default, all Y slices occur always.=Y-Scheiben werden benutzt, um ganze Scheiben mit einer gewissen Wahrscheinlichkeit auszulassen. Für jede Scheibe der Schematic-Region entlang der Y-Achse können Sie festlegen, dass sie nur mit einer gewissen Wahrscheinlichkeit auftritt. In der Registerkarte „Y-Scheiben“ müssen Sie die Höhe der Y-Scheibe festlegen (0 @= Boden) sowie eine Wahrscheinlichkeit zwischen 0 und 255 (255 steht für 100%). Standardmäßig treten alle Y-Scheiben immer auf.
 With a schematic node probability tool, you can set a probability for each node and enable them to overwrite all nodes when placed as schematic.
