Provide comparison in features and migration path for etelemetry users?

[yarikoptic]

What would you like changed/added and why?

Since this projects seems to be based on etelemetry which is still in use by some projects, I wondered if there could be some concise description of what migas provides on top and whether and how to migrate from etelemetry?

Do you have any interest in helping improve the documentation?

No

PS Might be of interest to @jbpoline
