+### Install desktop app from Famedly web app
+
+Most browsers support installing the Famedly web app on your desktop. 
+That means you can find the app by searching for installed apps and depending on your operating system, it might be added to your desktop or dock. 
+To install the web app on your Desktop, follow the following steps: 
+

+2. Go to your browsers settings menu (usually accessible through  **⁝**  or  **☰**  icon)
+3. Click on **Install Famedly...** (in Chrome, might be different on other browsers)
+(In Chrome and some other Chrome based browsers, you can click on the **desktop icon with the arrow down** in the address bar instead of doing steps 2 and 3)
+4. Click on **Install**
+5. A window with the Famedly app will open
+
+If you have problems with these instructions because you use a different browser than Chrome, you can also google “install web app” with the name of your browser added to the end of the search term to get instructions for your specific browser. Preferably use instructions that are posted directly by the supplier of your browser to get the most recent instructions. 
+
+Please keep in mind that the installed web app is still a window of the browser you installed it with, so you can refresh the app by pressing **F5** key or with a right click on the title bar of the window and then clicking on **refresh**.
