Vac RFCs ([Request for Comments](https://en.wikipedia.org/wiki/Request_for_Comments)) includes specs for the [Waku family of specs](https://rfc.vac.dev/spec/10/),
but also other things such as:
node discovery, data sync, recommendations around usage, spec process, interfacing with auxiliary systems such as distributed storage, payload encryption, and so on.
Vac, while having a core team of maintainers and contributors, is an open and permission-less organization.
**See [rfc.vac.dev](https://rfc.vac.dev) for an easy to browse index of all RFCs.**
Alternatively, [mscgenjs](https://github.com/mscgenjs/mscgenjs-cli) can be used to generate sequence diagrams (mscgenjs produces better quality figures especially concerning lines' spaces and figures' margins).
Once installed, the following command can be used to generate the sequence diagrams `mscgenjs -T png -i input.msc -o output.png`.
More details on the installation and compilation are given in [mscgenjs repository](https://github.com/mscgenjs/mscgenjs-cli).
You may try the online playground https://mscgen.js.org/ as well to get a sense of the output figures.
