@@ -11,33 +11,44 @@ History:
 Initially cimgui was developed by Stephan Dilly as hand-written code but lately turned into an auto-generated version by sonoro1234 in order to keep up with imgui more easily (letting the user select the desired branch and commit)
 
 Notes:
-* currently this wrapper is based on version [1.73 of Dear ImGui]
-* only functions, structs and enums from imgui.h are wrapped.
-* if you are interested in imgui implementations you should look LuaJIT-ImGui project.
-* overloaded function names try to be the most compatible with traditional cimgui names. So all naming is algorithmic except for those names that were in conflict with widely used cimgui names and were thus coded in a table (https://github.com/cimgui/cimgui/blob/master/generator/generator.lua#L58). Current overloaded function names can be found in (https://github.com/cimgui/cimgui/blob/master/generator/output/overloads.txt)

 * this is only needed (before compilation) if you want an imgui version different from the one provided, otherwise generation is already done.
 * you will need LuaJIT (https://github.com/LuaJIT/LuaJIT.git better 2.1 branch) or precompiled for linux/macOS/windows in https://luapower.com/luajit/download

+* you need to use also a C++ compiler for doing preprocessing: gcc (In windows MinGW-W64-builds for example), clang or cl (MSVC). (this repo was done with gcc)
 * update `imgui` folder to the version you desire.
-* edit `generator/generator.bat` on windows, or `generator/generator.sh` on linux, to choose between gcc, clang, cl or nocompiler. Run it with gcc, clang or cl and LuaJIT on your PATH.
-* as a result some files are generated: `cimgui.cpp` and `cimgui.h` for compiling and some lua/json files with information about the binding: `definitions.json` with function info, `structs_and_enums.json` with struct and enum info, `impl_definitions.json` with functions from the implementations info. 
-
+* edit `generator/generator.bat` on windows, or `generator/generator.sh` on linux, to choose between gcc, clang, or cl and to choose desired backends and whether imgui_internal is generated or not, comments are generated or not and if constructors are generated also with versions performing just initialization of structs provided by yourself (_Construct is added to the constructor names)
+* the defaults of generator are gcc as compiler, imgui_internal included and sdl, glfw, vulkan, opengl2 and opengl3 as backends.
+* edit config_generator.lua for adding includes needed by your chosen backends (vulkan needs that).
+* Run generator.bat or generator.sh with gcc, clang or cl and LuaJIT on your PATH.
+* as a result some files are generated: `cimgui.cpp`, `cimgui.h` and `cimgui_impl.h` for compiling and some lua/json files with information about the binding: `definitions.json` with function info, `structs_and_enums.json` with struct and enum info, `impl_definitions.json` with functions from the backends info. 
+* You can pass compiler flags to generator.sh or generator.bat by editing them at the end of the call to further specify the compiler behavior. (e.g. -DIMGUI_USER_CONFIG)
+* You are able to pass any extra argument to generator.sh (.bat) in the command-line.
+* If you are using different options than cimgui repo and if you want to keep them after a cimgui update, you can keep them in a copy of generator.sh (.bat) outside of cimgui folder where `cd cimgui/generator` is used before luajit call.
