Go to the Git repository of your document and change to the current Fedora release branch. Alternatively, you can create a new branch specifically for translations by branching the release branch, and then periodically merge updated content from the release branch to the branch with translations. After choosing the approach that is appropriate for you and changing to the branch, enter the following commands, replacing url with the URL of your document's project page on Transifex.net:

tx init

tx set --auto-remote url

This will create a .tx folder in your repository.
