+# Specify Alternate Location For Prisma Schema
+
+By default, Prisma looks for a schema in one of two locations:
+
+- `./prisma/schema.prisma`
+- `./schema.prisma`
+
+If it isn't in one of those two spots, then you'll get an error.
+
+You can manually specify an alternate location. One way is to use the
+`--schema` flag with all `prisma` commands. A less tedious approach
+([introduced in this PR](https://github.com/prisma/prisma/pull/3566)) is to
+specify the location in your `package.json`.
+
+```json
+{
+  "prisma": {
+    "schema": "../../packages/database/prisma/schema.prisma"
+  }
+}
+```
+
+This is handy in situations where your database schema and utils are packaged
+up separately, like in a monorepo. Here is an example of [a monorepo
+referencing a prisma schema in a separate
+package](https://github.com/skillrecordings/products/blob/b10dece7170abcb9076221c0863549e2291541ae/apps/testingaccessibility/package.json#L201-L203).
