Official Ubuntu Documentation

This site is where you can find the official documentation developed and maintained by the Ubuntu Documentation Project.

Choose your version of Ubuntu below to access the documentation for that version (find out which version of Ubuntu you are running).

If you don't find what you are looking for, visit the community help wiki for even more material!

If your version of Ubuntu is not listed above, it is no longer supported and does not receive security or critical fixes. Documentation for these releases of Ubuntu is no longer supplied, but information on how to upgrade to supported versions of Ubuntu can be found at the Upgrade Notes page.
