[ajmirsky]

Based on examples from other open-source repos in github:

• code of conduct for those participating in the project
• instructions for contributing to the project (including a pull request template to help facilitate)
• how to report a security vulnerability
• expectations of getting help with the project

Contributes to #671

Thanks for the PR! You have covered almost everything.
Another request. Can you please share the reference/source if you have used one?
For COC, its already there, but for the rest, I think we can mention the reference in the PR (as a comment, NOT as a commit).

contributing was inspired by: https://github.com/probot/template/blob/master/CONTRIBUTING.md

security was inspired by:

• https://github.com/microsoft/.github/blob/main/SECURITY.md
• https://github.com/skills/.github/blob/main/SECURITY.md
• https://github.com/standard/.github/blob/master/SECURITY.md?plain=1

support from:

• https://github.com/remarkjs/.github/blob/main/support.md?plain=1

pull request based on a few of the examples here:

• https://axolo.co/blog/p/part-3-github-pull-request-template

think that should cover all the primary sources i used.

@jerome-benoit actually, maybe there has been a release? I see releases listed in the changelog and there are tags listed, although none of them are listed in github as a release. and pypi has ocpp 1.0.

[ajmirsky]

but github's releases only have 0.26.0 as the last official release, although there is a 1.0.0-rc?

[jerome-benoit]

Given the current state of affair, an automated release process syncing deterministically future versions between GitHub and pypi has higher priority than the others comment I've done on that file in the other PR.

[ajmirsky]

@jerome-benoit just submitted a new PR #688 which changes the release workflow process to use the same version in pyproject.toml to publish to pypi, create a git tag and create a github release. Let me know if this addresses your concern?
