How do I edit Civics? For example edit a civic to rename it to something else, and edit it to edit the effects it does.

Firstly, this forum is not the correct place to put this, it would go in the Civ4 - Creation & Customization.

Secondly, many guides have been made for this, take a quick search.

Where should I look for these guides? I have no idea where to being looking, if you could please give me a link or tell me what subsection to look at.

generally the guides are in http://forums.civfanatics.com/forumdisplay.php?f=177

an example of a guide that may help you is http://forums.civfanatics.com/showthread.php?t=135549

Thank you I got it working now.
