Facing problem in contributing to framer motion open source

[Arun-chaitanya]

Hi There,
I want to contribute to Framer's open source.

1. I cloned the "motion" repository. And I ran the yarn install command on the root repo.
2. Now next step mentioned is "Run make bootstrap in the repo root." But this is giving me an error - make: *** No rule to make target bootstrap'. Stop.`.
3. If I do npm run dev, I am getting till created dist/framer-motion.js in 965ms.

Question) Can you tell me how to start the repo in my local?

Thanks.
