# Terminology used

To be clear with the terminology used in the code here:

- a *method* is an allowed JSON-RPC api method or a shell method
- a *methodGroup* is the grouping of similar methods (see `methodGroups.js`)
- a *permission* is a boolean which tells if an app is allowed to call a method or not
- a *request* is when an app prompts the shell to call a method
- a *requestGroup* is an array of *requests* whose methods are in the same *methodGroup*
