@BobrImperator let me know if you have any feedback as well – mainly interested in whether anything substantial is missing that should be in a README. There will be guides going into much more depth anyway.

Ideas:

• pace without arguments should output --help by default
• It'd be awesome to include the commands and their explanation in generated project's README. Currently it only has a project's name.
• I think that the blueprint is missing a common place for starting other server dependencies. If I needed to create a background task, I'm forced to repeat the setup in both tests and the actual server.

Questions:

• Would it be OK to add the cli/ crate to .gitignore?
  It causes quite a bit of bloat when searching up files.
  Alternatively, we could probably communicate that this is something the users won't have to touch anymore and they're free to exclude it themselves.

Yes, that's to be done still

I think that the blueprint is missing a common place for starting other server dependencies. If I needed to create a background task, I'm forced to repeat the setup in both tests and the actual server.

I think that's something for a later release. There's quite some questions coming with that, e.g. what do you use as a persistent queue for a background tasks implementation.

Would it be OK to add the cli/ crate to .gitignore?

No since we want that to be checked in with the project. I understand you want to exclude it from your editor but I don't think adding it to .gitignore is the right way to achieve that.
