Contributing to WordPress Core - Peter Wilson
1 like1,309 views
Almost everyone will have heard the phrase “don’t hack WordPress core” before, what’s less known is that it’s only the start of the saying. Don’t hack WordPress core, without contributing the hacks back. Contributing to WordPress core is like riding a bike, it takes a little effort to get started but once you learn it’s a skill you’ll never forget. You will be given a jump start on contributing, from how to use the bug tracker all the way to contributing a patch and getting your first props.
