+This page describes the process for reviewing, updating, and creating [OBO Foundry Principles](http://obofoundry.github.io/principles/fp-000-summary.html) by the OBO Foundry Editorial Working Group (EWG).
 
-This page describes the process for reviewing, updating, and creating [OBO Foundry Principles](http://obofoundry.github.io/principles/fp-000-summary.html).
+For the following, steps 1-5 are internal to the EWG and steps 6-7 are internal to the OBO Operations Committee. 
 
-- Discuss the principle on working group call
-- Write up proposed revisions as a GitHub issue (not a pull request)
-- Inform the Editorial WG via email that the ticket needs discussion (if it doesn’t happen automatically)
-- Two-week commenting period on GitHub issue tracker
-- Make any incremental improvements on the tracker
-- When the Editorial WG agrees on a final version, discuss on an Operations Committee call or via the issue tracke
-- Make a pull request
-- Two-week commenting period on the pull request
-- Upload final changes to OBO Foundry web site for public viewing.
+1. Discuss the principle during an Editorial Working Group (EWG) call.
+2. Write up proposed revisions as a [GitHub issue](https://github.com/OBOFoundry/OBOFoundry.github.io/issues/new?assignees=nataled&labels=attn%3A+Editorial+WG&projects=&template=obo-foundry-principles.md&title=Principle+%23%3CENTER+NUMBER+HERE%3E+%22%3CENTER+NAME+HERE%3E%22) (not a pull request).
+3. Inform the Editorial WG via [email](mailto:[email protected]) that the ticket needs discussion.
+4. Allow a two-week commenting period on the GitHub issue tracker, during which members of the EWG can suggest improvements.
+5. If necessary, discuss changes made during the commenting period and finalize the text.
+6. Once the EWG agrees on a final version, a member presents the text to the OBO Foundry Operations Committee for discussion during a meeting or via the issue tracker.
+7. Once the wording is approved by OBO Operations, a member of the EWG makes a pull request reflecting the consensus of previous discussions. Note that the pull request should be marked as 'draft' if it is a new principle.
+8. For new principles or major changes to existing principles, announce the proposal on the [obo-discuss mailing list](mailto:[email protected]) and the [obo-community #general Slack channel](https://app.slack.com/client/T01BAB621JR/C01BDKWDS91) and request public feedback.
+9. Allow a two-week commenting period on the pull request.
+10. If the feedback includes major changes or objections, re-discuss during an OBO Operations call and re-do any relevant steps indicated above.
+11. At the end of the commenting period, assuming no major changes are needed, a member of the EWG will merge the pull request (removing 'draft' status if appropriate) and thereby make the changes public.
 
 The need for a new principle can arise when an existing principle tries to cover too much and requires splitting, or as new needs arise within the community.
