+*** Selecting a backend
+
+Selecting a model or backend can be done interactively via the =-m= command of 
=gptel-menu=. Available registered models are prefixed by the name of their 
backend with a string like `ChatGPT:gpt-4o-mini`, where `ChatGPT` is the 
backend name you used to register it and `gpt-4o-mini` is the name of the model.

 *** Include more context with requests
 
 By default, gptel will query the LLM with the active region or the buffer 
contents up to the cursor.  Often it can be helpful to provide the LLM with 
additional context from outside the current buffer. For example, when you're in 
a chat buffer but want to ask questions about a (possibly changing) code buffer 
and auxiliary project files.
