@schickling @nikolasburk do we want the README to describe installing prisma globally at beta? currently we have upgraded to beta and added prisma as a script in package.json

[nikolasburk]

As discussed internally already, we don't want anyone to install the @beta of the CLI. As long as it's needed, let's have additional cd statements in the READMEs and then eventually remove them once the Prisma CLI can detect prisma.yml in subfolders.
