 Assuming that the current working directory is PyQSO's base directory (the directory that the Makefile is in), PyQSO can be installed via the terminal with the following command:
 
-   `make install`
+    make install
 
 Note: 'sudo' may be needed for this. Once installed, the following command will run PyQSO:
    
-   `pyqso`
+    pyqso
 
 Alternatively, PyQSO can be run (without installing) with:
 
-   `python3 bin/pyqso`
+    python3 bin/pyqso
 
 from PyQSO's base directory.

 The PyQSO documentation is stored in the `docs` directory. It can be built with the following command:

 There currently does not exist a Python 3-compatible Debian package for [Hamlib](http://www.hamlib.org). This library must be built manually to enable Hamlib support. As per the instructions on the [Hamlib mailing list](https://sourceforge.net/p/hamlib/mailman/message/35692744/), run the following commands in the Hamlib root directory (you may need to run `sudo apt-get install build-essential autoconf automake libtool` beforehand):
 
-```
-export PYTHON=/usr/bin/python3
-autoreconf --install
-./configure --with-python-binding
-make
-sudo make install
-```
+    export PYTHON=/usr/bin/python3
+    autoreconf --install
+    ./configure --with-python-binding
+    make
+    sudo make install
 
 You will also need to append the Hamlib `bindings` and `bindings/.lib` directories to the `PYTHONPATH`:
 
-   `export PYTHONPATH=$PYTHONPATH:/path/to/hamlib/bindings:/path/to/hamlib/bindings/.lib`
+    export PYTHONPATH=$PYTHONPATH:/path/to/hamlib/bindings:/path/to/hamlib/bindings/.lib
