How do I change the template?

Oh, If you are looking at using your website’s current design as a template theme, you’ll need to split it into PHP includes, and then in the index page add in your wordpress codex tags.

This can take a very long time, so have a go at it once you’ve got a good few days off work/school/etc.

For Your Reference: WordPress Template Tags

You’ll find everything you need in the wordpress codex.
