Use them :).

Presuming you're using them for scripts make sure to document:

1. what you're trying to match
2. what the regex is supposed to be doing
3. what each part of the regex is supposed to be doing

As you get better 3 can go away for simple regexes, but I suggest
always doing 1 and 2. I also suggest continuing with 3 for complex or
'cool' regexes.

You might also want to do:

4. give samples that do or don't match and why
