+## First Time Contributors: work from a fork

+When we have received and it has been process by a communty member, you will be added to the Plone organisation and added to the Contributors Team on GitHub. 
+You can create issues, add comments to existing issues, and discuss the development of Plone with others.
+Creating branches and editing code on our main repositories is restricted and granted to members who have been active in the Plone community for a while and have shown continued interest to contributing.

+- First, verify that your issue is valid by creating it and discussing it with other developers.
+- Then, create a fork of the repo in your own workspace, work on your code and make commits. 
+- When you want to run our code quality checks, create a Pull Request from your repo/branch to the main repository.
+- As a security measure, the first run of code Quality checks need to be [approved by a member in our Developers Team](https://docs.github.com/en/actions/managing-workflow-runs/approving-workflow-runs-from-public-forks)
+- A Developer with full access to the workflow will need to review and approve your Pull request.
+
+Please be aware that as long as you are working from a fork, you are the only developer being able to commit to your branch.
+Collaboration between developers on bigger pull requests is more efficient when these are done on branch on the main repo. 
+Therefore: as your first time contribution don't choose a too big problem to solve.
+Pick something that you can fix or complete from start to end.

+Developers are strongly encouraged to run these checks locally before creating a pull request.

 These checks are enforced automatically on every pull request, so you might as well save time and frustration by doing these checks locally first.
