+### raylib bindings
+
+Some people ported raylib to other languages in form of bindings or wrappers to the library, here is a list with the ones I'm aware of:
+
+ - [raylib](https://github.com/raysan5/raylib) : raylib **C/C++** version (default)
+ - [raylib-lua](https://github.com/raysan5/raylib-lua) : raylib **Lua** binding
+ - [raylib-lua-ffi](https://github.com/raysan5/raylib/issues/693) : raylib **Lua** ffi binding
+ - [raylib-go](https://github.com/gen2brain/raylib-go) : raylib **Go** binding
+ - [raylib-Nim](https://gitlab.com/define-private-public/raylib-Nim) : raylib **Nim** binding
+ - [raylib-cr](https://github.com/AregevDev/raylib-cr) : raylib **Crystal** binding
+ - [cray](https://gitlab.com/Zatherz/cray) - raylib **Crystal** binding
+ - [Graphics::Raylib](https://metacpan.org/pod/Graphics::Raylib) : raylib **Perl** wrapper
+ - [raylib-pascal](https://github.com/drezgames/raylib-pascal) - raylib **Pascal** binding
+ - [Raylib-cs](https://github.com/ChrisDill/Raylib-cs) : raylib **C#** binding
+ - [RaylibSharp](https://github.com/TheLumaio/RaylibSharp) : raylib **C#** binding
+ - [raylib-ruby-ffi](https://github.com/D3nX/raylib-ruby-ffi) : raylib **Ruby** binding
+ - [raylib-rs](https://github.com/deltaphc/raylib-rs) : raylib **Rust** binding
+ - [raylib-py](https://github.com/overdev/raylib-py) : raylib **Python** binding
+ - [raylib-haskell](https://github.com/DevJac/raylib-haskell) : raylib **Haskell** binding
+ - [raylib-java](https://github.com/XoanaIO/raylib-java) : raylib **Java** binding
+ - [raylib-chaiscript](https://github.com/RobLoach/raylib-chaiscript) : raylib **ChaiScript** binding
+ - [node-raylib](https://github.com/RobLoach/node-raylib) : **Node.js** raylib binding
+ - [raylib-odin](https://github.com/kevinw/raylib-odin): **Odin** raylib binding
+ - [raylib-factor](https://github.com/Silverbeard00/raylib-factor): **Factor** raylib binding
+ - *[raylib COBOL Usage example](https://github.com/Martinfx/Cobol/tree/master/OpenCobol/Games/raylib)*
+ - *raylib flat-assembler Usage example*: not uploaded yet...
+ 
+Missing some language? Check the [bindings not yet in this list](https://gist.github.com/raysan5/5764cc5b885183f523fce47f098f3d9b#bindings-not-yet-in-the-official-list) or create a new binding! :)
+ 
+Usually, raylib bindings follow the convention: `raylib-{language}`
+
+Let me know if you're writing a new binding for raylib, I will list it here and I usually 
+provide the icon/logo for that new language binding.

-### raylib bindings
-
-Some people ported raylib to other languages in form of bindings or wrappers to the library, here is a list with the ones I'm aware of:
-
- - [raylib C/C++ version (default)](https://github.com/raysan5/raylib)

 In **raylib 2.0** the full API has been carefully reviewed for better consistency, some new functionality has been added and the overall raylib experience has been greatly improved... The key features of new version are:
 
-**Complete removal of external dependencies.** Finally, raylib does not require external libraries to be installed and linked along with raylib, all required libraries are contained and compiled within raylib. Obviously some external libraries are related but only the strictly platform-dependant required ones, that comes installed with the OS.

+notes on raylib 2.5
+-------------------
+
+After almost one years since latest raylib installment, here it is **raylib 2.5**. A lot of work has been put on this new version and consequently I decided to bump versioning several digits. The complete list of changes and additions is humungous, details can be found in the [CHANGELOG](CHANGELOG), and here it is a short recap with the highlight improvements.
+
+New **window management and filesystem functions** to query monitor information, deal with clipboard, check directory files info and even launch a URL with default system web browser. Experimental **High-DPI monitor support** has also been added through a compile flag.
+
+**Redesigned Gamepad mechanism**, now generic for all platforms and gamepads, no more specific gamepad configurations.
+**Redesigned UWP input system**, now raylib supports UWP seamlessly, previous implementation required a custom input system implemented in user code.
+
+`rlgl` module has been redesigned to **support a unique buffer for shapes drawing batching**, including LINES, TRIANGLES, QUADS in the same indexed buffer, also added support for multi-buffering if required. Additionally, `rlPushMatrix()`/`rlPopMatrix()` functionality has been reviewed to behave exactly like OpenGL 1.1, `models_rlgl_solar_system` example has been added to illustrate this behaviour.
+
+**VR simulator** has been reviewed to **allow custom configuration of Head-Mounted-Device parameters and distortion shader**, `core_vr_simulator` has been properly adapted to showcase this new functionality, now the VR simulator is a generic configurable stereo rendering system that allows any VR device simulation with just a few lines of code or even dynamic tweaking of HMD parameters.
+
+Support for **Unicode text drawing**; now raylib processes UTF8 strings on drawing, supporting Unicode codepoints, allowing rendering mostly any existent language (as long as the font with the glyphs is provided). An amazing example showing this feature has also been added: `text_unicode`.
+
+Brand **new text management API**, with the addition of multiple functions to deal with string data, including functionality like replace, insert, join, split, append, to uppercase, to lower... Note that most of those functions are intended for text management on rendering, using pre-loaded internal buffers, avoiding new memory allocation that user should free manually.
+
+Multiple **new shapes and textures drawing functions** to support rings (`DrawRing()`, `DrawRingLines()`), circle sectors (`DrawCircleSector()`, `DrawCircleSectorLines()`), rounded rectangles (`DrawRectangleRounded()`, `DrawRectangleRoundedLines()`) and also n-patch textures (`DrawTextureNPatch()`), detailed examples have been added to illustrate all this new functionality. 
+
+Experimental **cubemap support**, to automatically load multiple cubemap layouts (`LoadTextureCubemap()`). It required some internal `rlgl` redesign to allow cubemap textures.
+
+**Skeletal animation support for 3d models**, this addition implied a redesign of `Model` data structure to accomodate multiple mesh/multiple materials support and bones information. Multiple models functions have been reviewed and added on this process, also **glTF models loading support** has been added.
+
+This is a just a brief list with some of the changes of the new **raylib 2.5** but there is way more, about **70 new functions** have been added and several subsystems have been redesigned. More than **30 new examples** have been created to show the new functionalities and better illustrate already available ones.
+
+It has been a long year of hard work to make raylib a solid technology to develop new products over it.

+/*
+    WELCOME raylib EXAMPLES CONTRIBUTOR!
+    
+    This is a bsasic template to anyone ready to contribute with some code example for the library,
+    here there are some guidelines on how to create an example to be included in raylib
+
+    1. File naming: <module>_<description> - Lower case filename, words separated by underscore,
+       no more than 3-4 words in total to describe the example. <module> referes to the primary
+       raylib module the example is more related with (code, shapes, textures, models, shaders, raudio).
+       i.e: core_input_multitouch, shapes_lines_bezier, shaders_palette_switch
+       
+    2. Follow below template structure, example info should list the module, the short description
+       and the author of the example, twitter or github info could be also provided for the author.
+       Short description should also be used on the title of the window.
+       
+    3. Code should be organized by sections:[Initialization]- [Update] - [Draw] - [De-Initialization]
+       Place your code between the dotted lines for every section, please don't mix update logic with drawing
+       and remember to unload all loaded resources.
+       
+    4. Code should follow raylib conventions: https://github.com/raysan5/raylib/wiki/raylib-coding-conventions
+       Try to be very organized, using line-breaks appropiately.
+       
+    5. Add comments to the specific parts of code the example is focus on.
+       Don't abuse with comments, try to be clear and impersonal on the comments.
+       
+    6. Try to keep the example simple, under 300 code lines if possible. Try to avoid external dependencies.
+       Try to avoid defining functions outside the main(). Example should be as self-contained as possible.
+       
+    7. About external resources, they should be placed in a [resources] folder and those resources
+       should be open and free for use and distribution. Avoid propietary content.
+       
+    8. Try to keep the example simple but with a creative touch.
+       Simple but beautiful examples are more appealing to users!
+    
+    9. In case of additional information is required, just come to raylib Discord channel: example-contributions
+    
+    10. Have fun!
