-## How to help updating the language pack (draft, not ready yet)
+## Installation
+
+To install a language pack, you must have the ProcessWire Language Support module installed. This is included with ProcessWire, so all you have to do is click to Modules > Language > Language Support > install.
+
+Once you have Language Support installed, you can install this language pack by going to Setup > Languages > Add New Language. Enter a title and name for the language and save.
+
+Next, you can install the files for the language pack. If your system supports ZIP uploads, you can simply drag the ZIP file for the language pack into the files field. If your system doesn't support ZIP uploads, then you'll want to unzip the language pack and drag the JSON files (as a group, or individually) into the files field. Save.
 
+Now you can test out the new language by editing our profile and selecting the new language.
+
+Menu items are translated after you log out and log in again.
+
+Big thanks to yellowled and nico for their initial work.

 Pull requests are welcome. Let's try to work together, to get fast updates of the german language pack when a new stable version is published.
