  *  CHANGELOG

- *  Noémi Shell X ver. 0.1
+ *  Noémi Shell X ver. 0.2
  *
- *  THos version is the first version of the Noémi Shell for UNIX like systems
+ *  This version introduses the cd command. In additon, this version is changing 
+ *  the prompt, to be more 'UNIX' like.
+ *  The prompt will now always show the current working directory, without requiring 
+ *  the 'pwd' command. The 'pwd' command is NOT removed. 
+ *  This version also introduces colors to the terminal, as highlighting. This is NOT syntax highligthing
+ *  that may come in a future update.
