* Instead of having two README versions, keep the Markdown version and rename it to README.md. Update the file to reflect new changes introduced by this commit. * Add CONTRIBUTING.md to clarify the contributing conditions. They should be also properly disclosed later in a blog post and maybe they can move to other repositories as well. * Add CODE_OF_MERIT.md. * Symlink CODE_OF_CONDUCT.md to CODE_OF_MERIT.md because apparently GitHub seems to only recognize CODE_OF_CONDUCT.md as the canonical name for this kind of codes? * Add a pull request template to please ask to not send pull requests.
