+## Error System for Repository
+
+Repository needs a good error system, and Results instead of just returning data;
+These errors should encompass:
+ - Validation Errors: these should allow forms to display issues, but not disrupt the flow
+ - Wrong Data / Not Authorized and other 400 base
+ - Not Found Error: for 404s
+ - Internal Errors: for 500s
