The first page you land on when you access Translation Manager shows a list of language sets have already installed in your Joomla! installation. It provides overview information on each language set. Most of the information are retrieved from the language set's XML file. It also displays the number of files included in the set.
To edit the information of a specific language set, you just click the selection circle on the left and then click the Edit button on the tool bar. On the page you can also delete a language set or create a new language set.
Occasionally you may want to switch the default language Joomla! uses to check the output of your translation. To make this switching easier, Translation Manager allows you to make the change without going back to Joomla!'s Language Manager.
Each language set consists of a collection of language files. To manage those files, you first select a language set and then click the View Files button. This will bring you to the Language Files page.
This page provides you many useful information to assess the progress and status of your translation. You can quickly glean what percentage of the translation for a file has been completed and how many phrases still have to be translated.
Sometimes there are language files not in your reference language anymore but still in the translation language. On the other hand, there may be language files in your reference language but not created in the translation language. The Language FIles page will indicate either case with an appropraiate icon.
Operations, such as deletion, changing publish state and creating new file, can be performed on this screen. The process of doing translation will be introduced in more details later.
Once again, the tooltips are your friends when you first use Translation Manager. If any information is not clear to you, try move the mouse pointer over to see the explanatory tooltip.
