    NOTE: if you use npm and corepack to install pnpm you will have two instances of pnpm. Make sure the version you're using is the correct version for the repo. Check the [pnpm docs](https://pnpm.io/installation) and [corepack](https://github.com/nodejs/corepack) for troubleshooting. Pnpm installed with npm will overrun corepacks pnpm instance.
