When i run make run-precheck from https://github.com/efabless/caravel_user_project_analog/blob/main/docs/source/index.rst i get this Erro 2

Any clues in the

precheck.log

? Looks like 1 check failed, but can't tell what it was from the limited screenshot.

Try changing your

README.md

file.

What do i need to do in README.md?

It appears that you just need to change it. You probably should add a description of your project.

It works, thanks, Mitch!!
