 There are eight projects in total.
 
+To set up the environment I have installed the following packages on my Linux
+Manjaro based system.
 
+```
+sudo pacman -S python-pandas --asdeps python-pandas-datareader python-numexpr \
+               python-bottleneck python-jinja python-scipy python-matplotlib  \
+               python-numpy
+```
+
+Use unzip with the `-n` flag to extract the archives for the different
+exercises. This makes sure that you do not override any of the existing files. I
+might add a makefile to automize this later.
+
+```
+unzip -n 20Spring_martingale.zip
