 In the above pattern you see *two* different forms of character classes, the `[A-Z]` and the `[[:alnum:]]`.
-Worth noting is that you can negate an expansion by putting a `^` inside it as such `grep '^[^A-Z].*' regex_03.txt` (not I used the first list because the animals list has no words starting with a capital letter).

+You should see it as a puzzle you're trying to solve.
+To get you started I urge you to go to [this](http://regextutorials.com/) website and start the **introduction to regex** section.
+It highlights automatically what your pattern is doing.
+Once you completed the introduction you should try their exercises and the ones I made for you below.
 
 ## Exercises
 
 Below are some practical exercises and files to go with them.
 Use them to test out you grepping skills and as inspiration for personal challenges.
+I've tested all of the challenges myself but there are a lot of different ways to get the same result with a different regex.
