   create database *uniworx*:
-  `createdb uniworx`
+  ```sh
+  $ createdb uniworx
+  ```
+
   after you added the database switch back to your own user with `Ctrl + D`.
 
   to access the database as user *uniworx* you now need to add a new linux-user called *uniworx*. when you get asked for a password enter *uniworx*.
-  `sudo adduser uniworx`
+  ```sh
+  $ sudo adduser uniworx
+  ```
 
   log-in as new user *uniworx*:
-  `sudo -i -u uniworx`
+  ```sh
+  $ sudo -i -u uniworx
+  ```
 
-  you can now use `psql uniworx` to execute SQL-commands and such.

 ## stack
   Install with:
-  `curl -sSL https://get.haskellstack.org/ | sh`
+  ```sh
+  $ curl -sSL https://get.haskellstack.org/ | sh
+  ```
 
   setup stack and install dependencies:
-  `stack setup`
+  ```sh
+  $ stack setup
+  ```
 
   During this step or the next you might get an error that says something about missing C libraries for `ldap` and `lber`. You can install these using
-  `sudo apt-get install libsasl2-dev libldap2-dev`
+  ```sh
+  $ sudo apt-get install libsasl2-dev libldap2-dev
+  ```
 
   If you get an error that says *You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.*
   Go ahead an install `libpq-dev` with
-  `sudo apt-get install libpq-dev`
+  ```sh
+  $ sudo apt-get install libpq-dev
+  ```
 
   Other packages you might need to install during this process:
-  `sudo apt-get install pkg-config`
-  `sudo apt-get install libsodium-dev`
+  ```sh
+  $ sudo apt-get install pkg-config
+  sudo apt-get install libsodium-dev
+  ```
 
   Build the app:
-  `stack build`
+  ```sh
+  $ stack build
+  ```
 
   This might take a few minutes if not hours... be prepared.
 
   install yesod:
-  `stack install yesod-bin --install-ghc`
+  ```sh
+  $ stack install yesod-bin --install-ghc
+  ```
 
 ## Add Dumy-Data and run the app
   After building the app you can prepare the database and add some dummy data:
-  `./db.sh -f`
+  ```sh
+  $ ./db.sh -f
+  ```
 
   Run the app:
-  `./start.sh`
-
-  `Devel application launched: http://localhost:3000`
-  means you are good to go.
+  ```sh
+  $ ./start.sh
+  ...
+  Devel application launched: http://localhost:3000
+  ```
 
   If you followed the steps above you should now be able to login as user Gregor Kleen using `LDAP:g.kleen@ifi.lmu.de` as dummy login.
