Hello @arbreezy , shouldn't we update the README to indicate that we have a new AI Backend available?

Yes we will add docs, I just didn't have much time yesterday; I want to test it as well before merging.

Tried it out, and my first observation is that the help text needs to updated to reflect these changes. I had to check the code to find out what to define as the backend.

Secondly, and this might be out of scope for the actual implementation, but if I want to do an analysis with the Azure OpenAI backend after I have authenticated, I would have so explicitly state that I'm using that as a backend, even when I have no other backends in my configuration file. @AlexsJones, this is probably something we can look into in another issue, right?

Third, and more importantly, I get an error when I run analyze with explain. This is the commands I ran:

> go run . auth -u https://rsopenaigptdemo.openai.azure.com/ -e rsk8sgpt -b azureopenai
Using azureopenai as backend AI provider
Enter azureopenai Key: Provider updated
key added

> go run . analyse -b azureopenai -e

hello @roberthstrand, Documentation has been added along with some basic checks when running k8sgpt auth to ensure you will use a valid ai provider/backend. Could you please run again a test with your Azure OpenAI deployment ?

Re: the analyze cli , I will address it, in a different PR; I agree there is no need to specify a backend if it's the only one in your configuration

Thanks in advance :) !
