+Installation
+============
+
+
+Prerequisites
+=============
+We recommend to use an environment manager like conda to install **VAMPyR** and its prerequisites.
+
+To set up an environment named `vamp-env` and activating it using conda we can run:
+```
+conda create -n vamp-env
+conda activate vamp-env
+```
+Other environment managers are also possible, but we will not cover them here.
+
+
+We will work from this environment for the rest of the installation process.
+
+Install options
+===============
+
+From conda
+----------
+
+The easiest way to install **VAMPyR** is to use the conda package manager.
+You can install **VAMPyR** by running the following commmand while in the `vamp-env` environment:
+```bash
+conda install -c conda-forge vampyr
+```
+This should install **VAMPyR** and all its dependencies. To use **VAMPyR** in a script or a Jupyter notebook, you can simply follow the instructions in the notebooks.
+
+
+From source
+-----------
+
+You can get the source code from github by running:
+```bash
+git clone https://github.com/MRChemSoft/vampyr.git
+```
+This will create a directory called `vampyr` in your current working directory, and download the source code there.
+
+Alternatively one can run
+```bash
+git clone [email protected]:MRChemSoft/vampyr.git
+```
+to clone the repository using ssh. This requires that you have set up an ssh key with github.
+
+
+
+Here we need to write about how to install **VAMPyR**. Possibilities:
+conda package, build from source, ....
