This looks great @jdnichollsc appreciate you improving the docs.

How would you update the readme now that onboarding is split out?

Friendly suggestion: I've been learning about this project over the last week, I think one thing that would help with onboarding is describing how to utilize the metrics built-in to Vixen. I've got Prometheus running, but I'm not seeing anything specific to my program showing up.

I've read the Metrics Support section of the README.md, but it doesn't describe how to collect metrics. Possibly a noob question, if it is I apologize.

edit: Figured it out. In my Vixen.toml in the [metrics] section, I had an invalid config.

[metrics]
endpoint = "http://localhost:9091"
job = "prometheus"
export-interval = 60

is all I needed and it just works now. Pretty simple.

Sorry for the delay @ultravigilante. We are finishing up some work and then doing a round of development on Vixen. Top priority for this cycle of work is user documentation.

Oh yes, please let me know if you want to see some ideas! I was creating this documentation because I'm learning about RPCs and Solana stuff, and I'm also looking for a new job so I'm improving my knowledge about Solana, and helping with the documentation is a nice way to learn more as well (learning by doing) <3
