+# glfw.c3l
+
+Pure [glfw](https://github.com/glfw/glfw) bindings for [c3 programming language](https://c3-lang.org/)
+
+
+## Installation
+
+To include these bindings into your project, do:
+```console
+$ git clone https://github.com/vssukharev/glfw.c3l.git   # Clone repo somewhere
+$ make                                                   # Create archive (make sure 'zip' is installed)
+$ mv glfw.c3l /path/to/project/libraries                 # Move archive to libraries directory of your project
+```
+
+Or just:
+```console
+$ git clone https://github.com/vssukharev/glfw.c3l.git /path/to/project/libraries/glfw.c3l # Add dependency without zip compression
+```
+
+Then you need to modify your `project.json`:
+```json
+{
+  // some stuff
+  "dependencies":  [ "glfw", /* Some other dependencies */ ],
+  // some other stuff
+}
+```
+
+Simply do `c3c run` to check whether everything is fine (make sure to have `glfw` installed on your system).
+
+
+## Usage with Vulkan
+
+To use specific features of GLFW for Vulkan (e.g., `glfwCreateWindowSurface`), you need to define `env::GLFW_INCLUDE_VULKAN` as though:
+```c++
+module std::core::env;
+const bool GLFW_INCLUDE_VULKAN = true
+
+module yourmodule;
+import glfw;
+// ...
+```
+
+## Usage with OpenGL
+
+Just use it, I haven't tested yet)
+
+
+## Naming
+
+- All functions are renamed from `glfwSomeStuff` to `someStuff` and called as `glfw::someStuff`
+- All types are renamed from `GLFWsometype` to `SomeType`
+- All constants are renamed form `GLFW_SOME_CONSTANT` to `SOME_CONSTANT` and accesed throguh `glfw::SOME_CONSTANT`
+
+
+## Breaking Changes
+
+- All functions, taking `void` as parameter, now take no parameters (due to C3 rules)
