On the search bar at the top...type:

Category:Templates

This will take you to the page that has all the templates. Look for the ones that say Template:Infobox (Faction Name)

Example: Template:Infobox Loyalist Chapters (for Space Marines)

Then simply copy the coding on that template. When you go to add an article, you simply paste the code you copied into it.

This is also in the guides, located in under the Help tab. Click on Guide Portal to access the guides. There is one called 'How to Post an Article'.
