Configuration-as-code-plugin: Add contribution guide

[martinmosegaard]

I would like a guide on how to contribute with issues and pull requests. Also tips for developing the code.

[jetersen]

Already there:
https://github.com/jenkinsci/configuration-as-code-plugin/blob/master/CONTRIBUTING.md

[oleg-nenashev]

a common name like CONTRIBUTING.md in the root would help for sure

[jetersen]

well docs/CONTRIBUTING.md should do the trick too 👍

[ewelinawilkosz]

we already have an issue for that - #33 and I will follow @casz advice to implement it as CONTRIBUTING file
so I will allow myself to close this one, please follow up on #33 if you're interested about the progress, we're planning to fix documentation in upcoming weeks

[jetersen]

@martinmosegaard as for tips
https://wiki.jenkins.io/display/JENKINS/Plugin+tutorial

useful for updating other plugins to support code as configuration plugin:
https://jenkins.io/doc/developer/plugin-development/pipeline-integration/

[ewelinawilkosz]

also both https://github.com/jenkinsci/configuration-as-code-plugin/blob/master/IMPLEMENTATION.md and https://github.com/jenkinsci/configuration-as-code-plugin/blob/master/PLUGINS.md contain some useful information for contributors

[jetersen]

perhaps this should be apart of the updated contributing.md? 😄

[ewelinawilkosz]

it will :)
