 ## Design principles
 
 The following design principles have been considered:
 
-* Simplicity of the codebase. 
+* Simplicity of the codebase.
 	* The code should be easy to understand and follow without in-depth Python knowledge.
 * Avoidance of external dependencies.
 	* The Python Standard Libary provides enough tools and libraries for quite many use cases.
-* Unix philosophy in general 
+* Unix philosophy in general
 	* *"Do one thing and do it well"*
 
 These are not rules set in stone, but should be revisited when doing big design choices.
