Contributing

Before submitting feedback, please familiarize yourself with our current issues list and review the HTTP/2 page and the working group home page. If you’re new to this, you may also want to read the Tao of the IETF.

Be aware that all contributions to the specification fall under the “NOTE WELL” terms outlined below.

The best way to provide feedback (editorial or design) and ask questions is sending an e-mail to our mailing list. This will assure that the entire Working Group sees your input in a timely fashion.
If you have editorial suggestions (i.e., those that do not change the meaning of the specification), you can either:

a) Fork this repository and submit a pull request; this is the lowest friction way to get editorial changes in.

b) Submit a new issue to Github, and mention that you believe it is editorial in the issue body. It is not necessary to notify the mailing list for editorial issues.

c) Make comments on individual commits in Github. Note that this feedback is processed only with best effort by the editors, so it should only be used for quick editorial suggestions or questions.

For non-editorial (i.e., design) issues, you can also create an issue on Github. However, you must notify the mailing list when creating such issues, providing a link to the issue in the message body.

Note that github issues are not for substantial discussions; the only appropriate place to discuss design issues is on the mailing list itself.

Working With the Drafts

The source for our current draft is draft-ietf-httpbis-http2.xml, using the RFC2629 format.

If you’re an editor, or forking a copy of the draft, a few things to know:

Pushing to the master branch will automatically generate the HTML on the gh-pages branch.
You’ll need xml2rfc, Java and Saxon-HE available. You can override the default locations in the environment. On a Mac with Homebrew, “saxon-b” is the right package.
Some of the make targets require GNU Make 4.0
Making the txt and html for the latest drafts is done with “make”.
Output for a specific draft can be made using “make http2” or “make hpack”.
