Github
Github (github.com) is used as a version control host for the D language source code and the dlang.org website pages. Github uses the Git version control system. A Github account is required in order to make changes to dlang.org web pages, D standard library (Phobos) or druntime source code, or the DMD compiler source code. The alternative D language compilers, GDC and LDC also use Github for their version control. Visit Github here: http://github.com
