contradiction regarding the installation of prisma in a monorepo

[nickjanssen]

The guide How to use Prisma ORM with Turborepo says to install prisma and @prisma/client inside a sub package.

2. Add a new database package to the hello-world monorepo[​](https://www.prisma.io/docs/guides/using-prisma-orm-with-turborepo#2-add-a-new-database-package-to-the-hello-world-monorepo)
Create a database package within the packages directory. Then, create a package.json file for the package by running:

cd packages/
mkdir database
cd database
touch package.json

Define the package.json file as follows:

{
  "name": "@repo/db",
  "version": "0.0.0"
}

Next, install the required dependencies to use Prisma ORM. Use your preferred package manager:

npm
yarn
pnpm
npm install prisma --save-dev

Yet the Help and troubleshooting section says to install it in the root:

...
Install Dependencies in the Root: Avoid version conflicts by installing Prisma ORM as a dependency
at the root of the monorepo.

Clarification around which one it should be would be appreciated.
