+# Contributing to Tangram ES
+
+The easiest way to help out is to submit bug reports and feature requests on our [issues](https://github.com/tangrams/tangram-es/issues) page.
+
+When submitting a bug report, please include:
+
+ - The device and operating system version that produced the bug
+ - The version or commit of Tangram ES that produced the bug
+ - Steps required to recreate the issue
+ - What happened
+ - What you expected to happen
+
+Thanks!
+
+## Building
+
+If you'd like to contribute code to the project or just make changes for fun, you'll need to make sure your development environment is set up correctly.
+
+ - [Developing for Mac OS X](platforms/osx/README.md#setup)
+ - [Developing for Ubuntu Linux](platforms/linux/README.md#setup)
+ - [Developing for Android](platforms/android/README.md#setup)
+ - [Developing for iOS](platforms/ios/README.md#setup)
+ - [Developing for Raspberry Pi](platforms/rpi/README.md#setup)
+
+## Development
+
+The tangram-es project is divided into two parts: a portable C++14 [core library](core) and the various [platform interfaces](platforms).
+
+To develop for the core library, it is usually easiest to build and test your changes using either the Mac OS X or Ubuntu desktop targets. These targets are the fastest and easiest to deploy and debug.
+
+## Code Style
+
+In general, code changes should follow the style of the surrounding code.
+
+When in doubt, you can use the provided clang-format style file for automatic styling.
+
+Install clang-format (available through brew or apt-get):
+```
+brew install clang-format
+```
+or
+```
+sudo apt-get install clang-format
+```
+
+Run clang-format with specified style (use -i to modify the contents of the specified file):
+```
+clang-format -i -style=file [file]
+```
