-## `package.json` entry options

-### `schema`
-
-The path to the desired `schema.prisma` file can be specified with the `prisma.schema` entry in the `package.json` file. The path defines the file the Prisma CLI should use when you run any of the CLI commands. Both absolute and relative paths are supported.

-```json file="package.json"
-{
-  "name": "my-project",
-  "version": "1.0.0",
-  "prisma": {
-    "schema": "./custom-path-to-schema/schema.prisma"
-  }
-}
-```

-This is available from version 2.7.0 and later.

-### `seed`
-
-The command used to populate the datasource is specified in the `prisma.seed` entry in the `package.json` file. It is used when `prisma db seed` is invoked or triggered.
