Welcome! Please see the About page for a little more info on how this works.
I would like to add some information to the README for core.match. However, a simple PR on the README seems to be against the procedure.
How do I contribute? I already have a signed CA.
Also, JIRA appears to be down (tried that first).
You opened a PR and the PR template you edited has instructions that the project does not take PRs and links to how to contribute (in particular a link to https://clojure.org/community/contributing).
The information there (https://clojure.org/community/contributing#_reporting_problems_and_requesting_enhancements) will direct you first here for filing problems (create in category Contrib libs / core.match) and to contribute patches (https://clojure.org/community/contributing#_development) directs you further to https://clojure.org/dev/dev.
The process involves:
The JIRA project as linked from the core.match readme is https://dev.clojure.org/jira/browse/MATCH (which is actually out of date but redirects to the current JIRA at https://clojure.atlassian.net/projects/MATCH and is up). I'll fix those links.
