Contributing to ELPA is very easy! There are a few simple rules to follow:

• ELPA accepts only free software. If in doubt check the DFSG to see if your license qualifies. We encourage all authors to assign their code to the FSF and to try to get their new packages into the official Emacs release.
• A package consisting of a single .el file must adhere to the Emacs Lisp header conventions (see the Emacs Wiki conventions as well). Additionally, there are a few ELPA-specific rules to follow:
  • package.el is pedantic about the header and footer comments, please make sure you have the correct number of semicolons and hyphens.
  • The Version field must have a "dotted numeric" value. That is, it must consist solely of numbers separated by periods. If you want to use an RCS Id or the like, you can introduce a Package-Version header that contains just the version number.
  • You should use ;;;###autoload comments everywhere appropriate. package.el extracts these for use during package activation. Note you may want to do this for more than just function definitions; for instance if you have a new major mode, you will want to add an autoload to add to auto-mode-alist.
  Email your .el file to us and we will upload it.
• If your package is more than one file, please contact us to discuss uploading. Larger packages require special handling, and will require a new file on your end as well.
• Please notify us if you know that your package will appear in a future Emacs release. This will let us update package.el to cope.
