+## Getting started: Install Linien
 
 Linien runs on Windows and Linux. For Windows users the [standalone
 binaries](#standalone-binary) containing the graphical user interface
 are recommended.
 These binaries run on your lab PC and contain everything to get Linien running on your RedPitaya.
 
-Both RedPitaya OS 1.x and 2.x are supported. However, support for OS 1.x will be dropped starting
-with Linien 2.x
-
-If you want to use the python interface you should [install it using pip](#installation-with-pip).
+Starting with Linien 2.0, only RedPitaya OS 2.x is supported. Linien 1.x works on RedPitaya OS
+but is no longer actively maintain.
 
 ### Standalone binary
 
-You can download standalone binaries for Windows on [the
-releases
-page](https://github.com/linien-org/linien/releases) (download the binary in the assets section of the latest version). For Linux users, we recommend installation via pip.

+### Installation of the server on the RedPitaya
+
+The easiest way to install the server component of Linien on the RedPitaya, is to use the graphical
+user interface. The first time you are connecting to the RedPitaya, the server is automatically
+installed.
+
+In case you are using the `linien-client`, the server can be installed with
+
+```python
+from linien_client.device import Device
+from linien_client.deploy import install_remote_server
+
+device = Device(
+    host="rp-xxxxxx.local",
+    user="root",
+    password="root"    
+)
+instalL_remote_server(device)
+```
+
+Finally, you can install the server manually, by connecting to the RedPitaya via SSH and
+then running
+
+```bash
+pip install linien-server
+```
+
+The server can then be started as a systemd service by running
+
+```bash
+linien-server start
+```
+
+on the RedPitaya. To check the status of the server, run
+
+
+```bash
+linien-server status
+```
+
+ For more options, run
+
+```bash
+linien-server --help
+```
