We saw in the bottom of the Codex home page that one of the
ways we could give back to WordPress is by contributing to the Codex documentation.
We could see here that the Codex is written in a wiki fashion.
What this means is that the site is built in a way that's
easy for people to edit and track change as a lot of people contribute.
As you get more and more familiar with WordPress
and feel the urge to contribute back to WordPress, you
may find that you want to read through bit more
about how you can start contributing to the WordPress codex.
If you speak another language, one of the huge ways that
people can contribute is by helping
to translate WordPress into different languages.
