Sometimes, all someone needs is a path to follow when they're looking to help out a project. That's why Ligaya Turmelle has posted this great list of ways that you can help out PHP and its surrounding projects (like PEAR).
Main items on the list are:
- General ways to help
- Helping the QA team
- Helping with PEAR
- Helping with the Documentation
- Helping via Perl (extensions)
- Heliping with the PHP Core
Under each of these main points there are several sub-points for even more ideas of places to get involved. It's a great list, and you can get even more information on helping in an area by clicking on its title to be taken to the official page.
