build and installation
----------------------
raylib binary releases for Windows, Linux, macOS, Android and HTML5 are available at the [Github Releases page](https://github.com/raysan5/raylib/releases).
raylib is also available via multiple [package managers](https://github.com/raysan5/raylib/issues/613) on multiple OS distributions.
#### Installing and building raylib on multiple platforms
[raylib Wiki](https://github.com/raysan5/raylib/wiki#development-platforms) contains detailed instructions on building and usage on multiple platforms.

- [Working on macOS](https://github.com/raysan5/raylib/wiki/Working-on-macOS)
- [Working on GNU Linux](https://github.com/raysan5/raylib/wiki/Working-on-GNU-Linux)
- [Working on Chrome OS](https://github.com/raysan5/raylib/wiki/Working-on-Chrome-OS)

*Note that the Wiki is open for edit, if you find some issues while building raylib for your target platform, feel free to edit the Wiki or open an issue related to it.*
#### Setup raylib with multiple IDEs
raylib has been developed on Windows platform using [Notepad++](https://notepad-plus-plus.org/) and [MinGW GCC](https://www.mingw-w64.org/) compiler but it can be used with other IDEs on multiple platforms.
[Projects directory](https://github.com/raysan5/raylib/tree/master/projects) contains several ready-to-use **project templates** to build raylib and code examples with multiple IDEs.
*Note that there are lots of IDEs supported, some of the provided templates could require some review, so please, if you find some issue with a template or you think they could be improved, feel free to send a PR or open a related issue.*
learning and docs
------------------
raylib is designed to be learned using [the examples](https://github.com/raysan5/raylib/tree/master/examples) as the main reference. There is no standard API documentation but there is a [**cheatsheet**](https://www.raylib.com/cheatsheet/cheatsheet.html) containing all the functions available on the library and a short description of each one of them, input parameters and result value names should be intuitive enough to understand how each function works.

/**********************************************************************************************
*
* rlgl v4.5 - A multi-OpenGL abstraction layer with an immediate-mode style API
*
* An abstraction layer for multiple OpenGL versions (1.1, 2.1, 3.3 Core, 4.3 Core, ES 2.0)
* that provides a pseudo-OpenGL 1.1 immediate-mode style API (rlVertex, rlTranslate, rlRotate...)
*
* When choosing an OpenGL backend different than OpenGL 1.1, some internal buffer are
* initialized on rlglInit() to accumulate vertex data.
*
* When an internal state change is required all the stored vertex data is renderer in batch,
* additionally, rlDrawRenderBatchActive() could be called to force flushing of the batch.
*
* Some additional resources are also loaded for convenience, here the complete list:
* - Default batch (RLGL.defaultBatch): RenderBatch system to accumulate vertex data
* - Default texture (RLGL.defaultTextureId): 1x1 white pixel R8G8B8A8
* - Default shader (RLGL.State.defaultShaderId, RLGL.State.defaultShaderLocs)
*
* Internal buffer (and additional resources) must be manually unloaded calling rlglClose().
*
*
* CONFIGURATION:
*
* #define GRAPHICS_API_OPENGL_11
* #define GRAPHICS_API_OPENGL_21
* #define GRAPHICS_API_OPENGL_33
* #define GRAPHICS_API_OPENGL_43
* #define GRAPHICS_API_OPENGL_ES2
* Use selected OpenGL graphics backend, should be supported by platform
* Those preprocessor defines are only used on rlgl module, if OpenGL version is
* required by any other module, use rlGetVersion() to check it
*
* #define RLGL_IMPLEMENTATION
* Generates the implementation of the library into the included file.
* If not defined, the library is in header only mode and can be included in other headers
* or source files without problems. But only ONE file should hold the implementation.
*
* #define RLGL_RENDER_TEXTURES_HINT
* Enable framebuffer objects (fbo) support (enabled by default)
* Some GPUs could not support them despite the OpenGL version
*
* #define RLGL_SHOW_GL_DETAILS_INFO
* Show OpenGL extensions and capabilities detailed logs on init
*
* #define RLGL_ENABLE_OPENGL_DEBUG_CONTEXT
* Enable debug context (only available on OpenGL 4.3)
*
* rlgl capabilities could be customized just defining some internal
* values before library inclusion (default values listed):
*
* #define RL_DEFAULT_BATCH_BUFFER_ELEMENTS 8192 // Default internal render batch elements limits
* #define RL_DEFAULT_BATCH_BUFFERS 1 // Default number of batch buffers (multi-buffering)
* #define RL_DEFAULT_BATCH_DRAWCALLS 256 // Default number of batch draw calls (by state changes: mode, texture)
* #define RL_DEFAULT_BATCH_MAX_TEXTURE_UNITS 4 // Maximum number of textures units that can be activated on batch drawing (SetShaderValueTexture())
*
* #define RL_MAX_MATRIX_STACK_SIZE 32 // Maximum size of internal Matrix stack
* #define RL_MAX_SHADER_LOCATIONS 32 // Maximum number of shader locations supported
* #define RL_CULL_DISTANCE_NEAR 0.01 // Default projection matrix near cull distance
* #define RL_CULL_DISTANCE_FAR 1000.0 // Default projection matrix far cull distance
*
* When loading a shader, the following vertex attribute and uniform
* location names are tried to be set automatically:
*
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_POSITION "vertexPosition" // Bound by default to shader location: 0
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TEXCOORD "vertexTexCoord" // Bound by default to shader location: 1
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_NORMAL "vertexNormal" // Bound by default to shader location: 2
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_COLOR "vertexColor" // Bound by default to shader location: 3
* #define RL_DEFAULT_SHADER_ATTRIB_NAME_TANGENT "vertexTangent" // Bound by default to shader location: 4
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MVP "mvp" // model-view-projection matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_VIEW "matView" // view matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_PROJECTION "matProjection" // projection matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_MODEL "matModel" // model matrix
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_NORMAL "matNormal" // normal matrix (transpose(inverse(matModelView))
* #define RL_DEFAULT_SHADER_UNIFORM_NAME_COLOR "colDiffuse" // color diffuse (base tint color, multiplied by texture color)
* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE0 "texture0" // texture0 (texture slot active 0)
* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE1 "texture1" // texture1 (texture slot active 1)
* #define RL_DEFAULT_SHADER_SAMPLER2D_NAME_TEXTURE2 "texture2" // texture2 (texture slot active 2)
*

*
* - OpenGL libraries (depending on platform and OpenGL version selected)
* - GLAD OpenGL extensions loading library (only for OpenGL 3.3 Core, 4.3 Core)
