Using GitHub Actions has a few advantages over using Travis CI:
* More jobs can be run in parallel
* All CONSUL repositories on GitHub will be configured automatically
Besides, Travis have recently changed their policy twice. First, they
announced their site for free software projects would be shut down but
free software projects could still use their site for private projects.
And then, they limited the usage of their services for free software
projects.
Just like we used to do with Travis, we're enabling builds for pull
requests but not for pushed branches.
We're also building the master branch. Even if we never push to the
master branch directly, we're aware other CONSUL repositories do, so
we're running the tests for this case.
We split the section about pull requests, reducing the steps needed to
contribute since there's already a link to help people working on their
first pull request, and the rest don't need to be told to fork the repo.
Current team members don't use twitter very often, the `Not-ready` label
has has been removed, and issue assignees are sometimes deceiving.
We're also removing the "Limpiar" section from the Spanish document,
which had already been removed from the English document in commit
8eb8bb9a.
Why:
* Try to make the repo more friendly for first time contributors and any contributor on general
How:
* Adding a PRs-welcom badget that links to the issues list filtered by PRs-welcome label
* Adding a Link to on the Contributing guide to a free course about Pull Request and Contributions on Github.
