Thank you! This is certainly a good start, but what about:

• Steps for creating good issues or pull requests.
• Links to external documentation, mailing lists, or a code of conduct.
• Community and behavioral expectations.

I think at least the first item should be addressed right away.

Perhaps the first item could be better addressed with https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/about-issue-and-pull-request-templates?

For the third item, this probably helps: https://docs.github.com/en/communities/setting-up-your-project-for-healthy-contributions/adding-a-code-of-conduct-to-your-project.

It would be good to have a guide similar to https://github.com/php/php-src/blob/master/CONTRIBUTING.md but shorter.

[cmb69]

Issue templates might be useful, but some more general info (like in php-src's CONTRIBUTING.md as @kamil-tekiela pointed out) should be good for now.

Regarding a CoC: IIRC that was discussed quite a while ago for php-src, but went nowhere. I'm afraid the situation would be the same for web-php.

Updated CONTRIBUTING.md based on CONTRIBUTING.md of php/php-src!

[localheinz]

Also see #621.

Also see #621.

[cmb69]

Thank you! Much better, in my opinion, but still a few tweaks could be applied.

[localheinz]

@cmb69@kamil-tekiela

Adjusted!

[cmb69]

Thank you, @localheinz! Wrt. #621, we can adjust CONTRIBUTING.md later.

Thank you, @cmb69 and @kamil-tekiela!
