Adds details about the app, how to run it, how to develop, and badges.

Worth showing how to run a Hydra console instead?

[davidcmoulton]

(A few occurrences): the first line of output running curl --verbose localhost:8080 is Rebuilt URL to: localhost:8080/

So the text should probably read

curl --verbose localhost:8080/

from the get go.

[thewilkybarkid]

Maybe curl --include http://localhost:8080/ to just show the full response too.

(Though I don't see the Rebuilt URL.)

Very succinct, good use of collapsible sections. I've not tried to follow the instructions but assuming they all run, then it looks good.
