 # Parkmanne
 ## A stroll in the park
-Parkmanne aims to achieve provisionary effectiveness in the sector of parking. This problem had. 
+
+#TODO
+1. fix password of admin(probably buffer of input cusing the problem)
+2. add adress to customer
+3. billing
+4. delete/edit admin
+
+
+
+This is a graph of how everything is connected.
+If you need to add functionality that doesn't fall in any of these, and you're unsure of what to include, you can decide something like this:
+
+Take my customer class for example. 
+It needs to be able to save to db, so it needs data.
+It needs to modify and save park_time objects, so it needs those. 
+It needs to encrypt and decrypt passwords. BUT since data already includes encrypt, it doesn't have to be encrypted.
+So customer includes those.
+
+Another example is Parkspot.
+It needs information about both customers and save to the database.
+Since customer also includes data, i don't have to include it again.
+
+Last example:
