 ## How to Contribute
 When working on reverse engineering the client, you can store subroutine names within the database files used by [Firefall DISASM Name Manager](https://github.com/themeldingwars/Firefall-DISASM-Name-Manager). These can then be committed back into this repository for users to add to their own local databases.
 
+### Allowed Charcters In Names
+The following is a list of characters approved for names that have been confirmed to be handled gracefully in all supported applications.
+
+`.:_0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz`
+
+Pull Requests will not be merged that contain characters outside of the above list unless ample reasoning is provided for why the list should be expanded.
+
+### Duplicate Name Handling
+When duplicate names occur, they should be handled by appending `_#` to the end of the name. Where the `#` is incremented for each additional occurrence.
