 ## Philosophy
 
 🔑 Our philosophy is to keep things clean, simple and minimal. 
-MarkText is constantly changing and we want these improvements to align with our philosphy. For example, look at the side bar and tabs; these two panels provide awesome functionality *and* aren't distracting to the user. We'll continue adding more features (like plugins) that can be activated via 'settings' to improve MarkText. This will allow everyone to customize MarkText for their needs and provide a minimal default interface.
