+# Nexus Example With Prisma
+
+This example shows how to use Nexus with [Prisma](https://prisma.io) without the [Prisma plugin for Nexus](https://nxs.li/plugins/prisma). This approach is lower-level and here for reference reasons. Generally, you would want to use the Prisma plugin.
+
+### Try It
+
+```
+npm install
+npx prisma generate
+npx prisma migrate save --experimental
+npx prisma migrate up --experimental
+```
+
+Terminal 1
+
+```
+npm run dev
+```
+
+Terminal 2
+
+```
+npm run dev:typecheck
+```
