+
+Compilation
+-----------
+
+It is very simple, written in ANSI C. The one and only dependency it has is the SDL2 library. Just issue `make` in the "src"
+directory, and that will autodetect your operating system (Linux, BSD, MacOSX and Windows with mingw).
+
+It also needs some [data files](https://gitlab.com/bztsrc/mtsedit/blob/master/docs/blocks.md), which can be found
+[here](https://gitlab.com/bztsrc/mtsedit/tree/master/data).
