 # Questionable Örbital Mechanics
 
 ## What is this?
-Questionable Örbital Mechanics - or as i like to call it: *QÖM* - is an open-source Space Simulation "Game" written in Lua using the Löve game engine.
+Questionable Örbital Mechanics - or as we like to call it: *QÖM* - is an open-source Space Simulation "Game" written in Lua using the Löve game engine.
 
 For now it is very basic, as it is still heavily in development.
 
 
 ## How do i play this game?
 In order to play this game you need to ...
-1) ...have the Lua (5.4.3) programming language installed
+1) ...have the Lua (5.4.3) programming language installed (optional, as Löve comes with Lua)
 1) ...have the Löve (11.3) game engine installed
 
 For now this is the only way to play this game. In future there will be binary versions availabe.
