Hi @Algernon
Not sure about where to read about templates. I’ve mostly learned by watching/doing. For the most part an admin would create a Template by typing the following into the wiki search bar:
Template:template_name
next hit enter
Template name will be in red type above search results. click on that.
Next edit the template like you would a regular page. If multiple pages use the same info you would want to use the template for that common info. Once that is done you only add {{page title}} in the spot where you want it on the wiki page(s).
When you want to make changes to that info at a later date you only have to do it to the template. Not multiple pages.
If you know the name that you want the templates I can create them for you. Then you can edit away.
Also, if you have any more questions or I didn’t explain it will enough please let me know.
