 Compilation
 -----------
 
-Use recent Lazarus (1.2.x) with Freepascal (2.6.x) to compile.
-Viewers need SDL 1.2 and OpenGL 1.x support to work. I tested 32bit versions only, 64bit will most probably work as well.
+Use recent Lazarus (1.6 and higher) with Freepascal (3.0 and higher) to compile. 
+Older versions may work, but are not recommended.
+Terrain viewer needs SDL 1.2 and OpenGL 1.x support to work. I tested 32bit versions only, 64bit will most probably work as well.
+Model viewer needs OpenGL2, SDL2 and ImGui (through cimgui). Only 64bit is tested.

+Bundle pack uses Rust, so (try to) compile with Cargo.
