+# Installation
+There are two methods to install the environment which is needed for following
+the NIFTy tutorial. First, install it regularly into the home folder of your
+machine. Second, use a Docker container. The advantage of the second approach is
+that it is going to work without any problems most likely. Its downsides are:
+Root access to start the Docker container (security implications), a full Docker
+installation (security implications), you need to be familiar with Docker in
+order to get your results out of the container.
+
+## Standard
+
+- Install git, python3 and python3-pip, python3-scipy, python3-matplotlib. On
+  Debian-based systems possibly:
+
+```
+# apt-get update
+# apt-get install git python3-pip python3-scipy python3-matplotlib 
+```
+
+- Install our Fouier transform package `pypocketfft`:
+
+```
+$ pip3 install git+https://gitlab.mpcdf.mpg.de/mtr/pypocketfft.git
+```
+
+- Clone this repository:
+
+```
+$ git clone --recursive https://gitlab.mpcdf.mpg.de/ift/nifty_tutorial.git
+```
+
+- Install `nifty`:
+
+```
+$ cd nifty_tutorial/nifty
+$ python3 nifty_tutorial/nifty/setup.py install -f
+```
+
+## Docker
+
+- Build the image:
+
+```
+$ git clone https://gitlab.mpcdf.mpg.de/ift/nifty_tutorial.git
+# docker build -t niftytutorial .
+```
+
+- Start a container and mount your local folder `/mnt` into the folder `/mnt` in
+  the container. Do this only if you know what you are doing!
+
+```
+# docker run -v /mnt:/mnt -it niftytutorial
+```
+
+## Double-check the installation
+
+Run the scripts `*_solution.py` from the repository, check that they run through
+and look at the output plots.
