+=====================
+Cpp Eclipse Projects
+=====================
+
+For additional information on using Eclipse CDT see
+`the MDN page
+<https://developer.mozilla.org/en-US/docs/Eclipse_CDT>`_.
+
+The build system contains alpha support for generating C++ Eclipse
+project files to aid with development.
+
+Please report bugs to bugzilla and make them depend on bug 973770.
+
+To generate a C++ Eclipse project files, you'll need to have a fully
+built tree::
+
+   mach build
+
+Then, simply generate the C++ Eclipse build backend::
+
+   mach build-backend -b CppEclipse
+
+If all goes well, the path to the generated workspace should be
+printed.
+
+To use the generated C++ Eclipse project files, you'll need to
+have a Eclipse CDT 8.3 (We plan to follow the latest Eclipse release)
+`Eclipse CDT plugin
+<https://www.eclipse.org/cdt/>`_
+installed. You can then import all the projects into Eclipse using
+*File > Import ... > General > Existing Projects into Workspace*
+-only- if you have not ran the background indexer.
+
+Updating Project Files
+======================
+
+As you pull and update the source tree, your C++ Eclipse files may
+fall out of sync with the build configuration. The tree should still
+build fine from within Eclipse, but source files may be missing and in
+rare circumstances Eclipse's index may not have the proper build
+configuration.
+
+To account for this, you'll want to periodically regenerate the
+C++ Eclipse project files. You can do this by running ``mach build
+&& mach build-backend -b CppEclipse`` from the
+command line.
+
+Currently, regeneration rewrites the original project files. **If
+you've made any customizations to the projects, they will likely get
+overwritten.** We would like to improve this user experience in the
+future.
