+## exaequOS
+
+exaequOS (https://exaequos.com) is a Unix-like operating system fully running in a Web browser. It allows you to build and share cross platform applications with various languages C, C++, Javascript, Lua, Tcl, Scheme, Forth, etc... There are running in Web Assemmbly in the Web browser.
+
+#### Developer's guide
+
+You fill find the developer's guide here: https://www.exaequos.com/doc/build/html/dev.html
+
+#### Raylib for exaequOS
+
+Raylib has been compiled in Web Assembly for the Web browser with OpenGL ES 3.0 (WebGL 2.0), GLFW3 and Wayland thanks to emscripten-exa toolchain. This toolchain is an adaptation of emscripten for supporting exaequOS syscalls.
+
+#### Text editors
+
+There are 5 text editors embedded in exaequOS for editing source code and storing it in the local persistent file system:
+
+* Monaco editor: /usr/bin/mc
+* Vim: /usr/bin/vim
+* microEMACS: /usr/bin/em
+* nano: /usr/bin/nano
+* ed: /usr/bin/ed
+
+*Note* Files can be imported/exported into exaequOS with the `exio` command line tool.
+
+#### Source code
+
+You will find source code on GitHub:
+
+* exeaquOS kernel: https://github.com/baudaux/exa-kernel
+* emscripten-exa: https://github.com/baudaux/exa-kernel
+* exa-wayland: https://github.com/exaequos/exa-wayland
+
+## Developping Raylib apps
+
+There are currently three ways of developping a Raylib app for exaequOS:
+
+* In C/C++ with emscripten-exa toolchain
+* In Javascript with QuickJS 2024-02-14
+* In Lua with Lua 5.4.6 interpreter
+
+#### C/C++
+
+Developer's guide explains how to use emscripten-exa toolchain for building an app in C/C++ from your host machine (using Docker or not).
+
+#### QuickJS
+
+Raylib bindings for QuickJS have been developped and source code is there: https://github.com/exaequos/raylib-qjs
+
+These bindings include raylib, raymath and raygui. There are loaded with this line on top of the Javascript file:
+
+	import * as ray from 'raylib_qjs.so'
+
+Example of Raylib app in Javascript:
+
+	import * as ray from 'raylib_qjs.so'
+	
+	ray.InitWindow(800, 600, "Raylib app");
+	
+	while (!ray.WindowShouldClose()) {
+	
+		ray.BeginDrawing()
+		
+		ray.ClearBackground(ray.RAYWHITE);
+		
+		ray.DrawText("Raylib app in Javascript running in exaequOS", 100, 200, 20, ray.BLACK);
+		
+		ray.EndDrawing()
+	}
+	
+	ray.CloseWindow();
+
+## Lua
+
+Raylib bindings for Lua have been developped partially: https://github.com/exaequos/raylib-lua
+
+There are loaded with this line on top of the Lua file:
+
+	require "raylib_lua"
+	
+	InitWindow(800, 600, "Raylib app")
+	
+	while (not WindowShouldClose()) do
+	
+		BeginDrawing()
+		
+		ClearBackground(RAYWHITE)
+		
+		DrawText("Raylib app in Javascript running in exaequOS", 100, 200, 20, BLACK)
+		
+		EndDrawing()
+	end
+	
+	CloseWindow()
+
+## Publishing Raylib app
+
+Once developped, the app can be published on the exaequos store for being accessed by everybody. It can also be accessible from itch.io.
