android-x86 is a project to port Android open source project to x86 platform, formerly known as "patch hosting for android x86 support".

A few months after we created the project, we found out that we could do much more than just hosting patches. So we decide to create our code base to provide support on different x86 platforms, and set up a git server to host it.
