I’m not personally involved in this project, but here are some general places to start:
- Firstly, check out the Contributing guide for general information about contributing.
- In addition to general information about contributing, this asks for help translating guide articles.
- Besides submitting your own translation edits, you can also help by reviewing Portuguese language PRs to recommend either improvements or acceptance.
- The next version of Free Code Camp will be a significant change to the curriculum. This version will be the first one to be available in multiple languages. See that post for details on contributing to the effort.
