 ## What's been implemented so far
 * A CSV-Parser - featuring a Row, Header, CSVParser, and Error class contained in namespace CSV. The CSV-Parser can be called with a Header Element containing the files structure and a filename to open. If the file does not exist it is created. In case the Header does not match the given header the CSVParser corrects it. Elements inside the CSV file can than be accessed via the .getRow function and the index operators (e.g. [0] or ["SOMEHEADER"])
-* A User Class that takes care of registration, login, and instantiating the Userinfo class with the User's info
-* A Userinfo Class that stores the information regarding a certain UID and provides it for the Library to use
-* A Library Class that features a run_library task - letting the User login, out, and exit
-
-## Future Features
-* Rent a book
-* Read a book
-* Show my books
-* List books
-* Buy a book
-* return a book
-* Different User types -> Publisher that can publish books
+* A User Class that takes care of registration, login, and instantiating the Userinfo - it also provides access to all the user related data
+* A Library Class that holds the main loop and provides the basic functions listed below
+
+## Features
+* Rent a book -> The function looks up the availability and updates both the userinfo and the inventory
+* Read a book -> still in progress
+* Show my books -> function mainly provided by the userclass which returns a string with all the public infos
+* List books 
+* Buy a book -> same as rent a book - this function only writes the book to the `owned` category in userinfo
+* return a book (unavailable)
+* Different User types -> User is fully supported while Publisher is only implemented on a surface level
 
 ## File structure
 Using SQL for that project would have probably been the smarter way, but that never was the purpose, right?!
-I wanted to have to come up with my own way of organizing data and handling it in my custom-made C++ functions. So here's how I organized the Userinfo:
-* The ```User``` Class reads and writes users in this data/Userfile.csv file in the following order ```USERNAME,PASSWORD,UID``` whereas ```UID``` is a unique 7 letter string with either a 'U', 'A' or 'P' at the beginning (for User, Admin, Publisher) followed by a unique six-digit number
-* The ```UID``` can be found in the data/Userinfo.txt file handled by the ```Userinfo``` class. The information here is presented like this

-* Finally the ```Library``` Class has access to data/Inventory.csv with this file structure ```BID,NAME,AUTHOR,COPIES,RENTED,LINK```. The ```BID```s mentioned in the Usersinfo match one of the books in the inventory which in return holds the path ```LINK``` to the books file in data/books

 ## Installation and Usage
 * Download the Code from Github - see Releases for latest Version (I advise you let the data/ folder where it is - no handling included for that yet)

 ### What to do if nothing works anymore
-Press CTRL+C go into data/ and delete the three database files. On the next startup, the program should simply create new files and it should run again. 
-But don't forget to share the issue you ran into with us ;)

 ## Development 
-Development happens in feature branches like ```library_feature``` so that the main branch always is funtional. Before the feature branch is ready to merge bugs must be fix in specific bug branches marked with ```iss``` or ```feat```.
