 # Schematic Editor [`schemedit`]
 
 ## Version
-1.1.0
+1.4.1
 
 ## 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.
