Having a knowledge base on your website is a great idea to provide your users with an area where they can visit and find out detailed information to their queries.
Each knowledge base article can be customised to your requirements, you can even upload files as attachments to each article, and they have a rating system so you can gain valuable feedback on their usefulness.
Knowledge bases can be useful for supporting documentation i.e. advice, legal information, basically anything you can think of!!
