Facilitate onboarding of new contributors

[Daniel-Mietchen]

There are several components to this:

• good documentation both within the code as well as in the repo (e.g. README) and issues (e.g. labels)
• interoperability (e.g. indentation style)
• behavioural guidance (e.g. code of conduct or issue templates)

Some more points in this post (albeit with a certain bias for Node).

We already have

• README.rst
• LICENSE
• label:good first issue
• Add a Code of Conduct #941 for a Code of Conduct
• Add issue templates #942 for issue templates
• Add pull request template #943 for pull request templates.

  • Rule 5: Have and enforce a code of conduct
  • Rule 6: Develop forms of legitimate peripheral participation
  • Rule 7: Make it easy for newcomers to get started
  • Rule 8: Use opportunities for in-person interaction—With care
  • Rule 9: Acknowledge all contributions
  • Rule 10: Follow up on both success and failure
