From Fedora Project Wiki
Step 1: Find the English version of the page
English is the base language for the Fedora Project wiki, so there needs to be an English version of the page you are working on. (If there isn't an English version of the page you are working on, see #Handling translations without an English version.)
If there is already a language template at the top of that page, click [edit] on the right side of the language box and move to step 4; otherwise, continue to step 2.
Handling translations without an English version
If the page you create doesn't have an English version, create a new page for the English version, add the {{autolang}} template as noted above, and then add the {{needs english}} template. This will flag the page for needing an English translation as well as create a base page.
