I will like to give back to the community a little of what it has giving me, and I will like to start contributing to some open source projects. Once I choose the project I will like to start the right way to contribute something. Could be code, but also I am up for even documentation. What could be a good way to contribute to Open source project.
Thanks for all your helps. And I am sure this will be helpful to other people as well.
That's up to the project and can't be answered categorically for the most part.
You have to look at the individual project, figure out what their needs are, find out what you can do for them, and do it.
Most of the time, it's figuring out something you need that you think someone else might and providing it to them in whatever way they'd like.
it's a popular question, so you might want to refer to this:

For me the best way is to find something needed and add it. Sometimes that need translates to documentation, learn an API and write a tutorial. Sometimes that need translates to patches.
You can also start but hanging out in the IRC channel, if applicable, and answering any questions that pop up. Helping other users is a good way to start learning the application and very useful to the community in general.
