 ## Installation
 
-`pip` and `conda` support will follow in the near future.
+### pip / conda
+
+`conda` support may follow in the near future.
+
+You can install via `pip` using
+
+```
+
+pip install paseos
+
+```
+
+This requires `Python 3.8` due to [pykep's limited support of pip](https://esa.github.io/pykep/installation.html). If you encounter problems, please consider setting up a dedicated `conda` environment to install dependencies.

+The following code snippet shows how to add a power device to a [SpacecraftActor](#spacecraftactor).

 Alternatively to the default `paseos.PowerDeviceType.SolarPanel` you can also use `paseos.PowerDeviceType.RTG`. The only difference at the moment is that [RTGs](https://en.wikipedia.org/wiki/Radioisotope_thermoelectric_generator) also charge in eclipse.

 #### Thermal Modelling
 
 To model thermal constraints on spacecraft we utilize a model inspired by the one-node model described in [Martínez - Spacecraft Thermal Modelling and Test](http://imartinez.etsiae.upm.es/~isidoro/tc3/Spacecraft%20Thermal%20Modelling%20and%20Testing.pdf).
