+## Usage with Prisma Accelerate or Prisma Postgres
+
+When using the Rust-free version of Prisma ORM with [Prisma Accelerate](/accelerate) or [Prisma Postgres](/postgres), you **should not** use driver adapters. Instead, you can directly instantiate Prisma Client with the appropriate extension.
+
+### 1. Set `engineType` on the `generator` block
+
+```prisma file=schema.prisma
+generator client {
+  provider        = "prisma-client" // or `prisma-client-js`
+  output          = "../generated/prisma"
+  engineType      = "client" // enable Prisma ORM without Rust
+}
+```
+
+### 2. Re-generate Prisma Client
+
+To make the configuration take effect, you need re-generate Prisma Client:
+
+```terminal
+npx prisma generate
+```
+
+### 3. Instantiate Prisma Client with Accelerate
+
+Import and instantiate Prisma Client with the Accelerate extension:
+
+```typescript
+import { PrismaClient } from "./generated/prisma";
+import { withAccelerate } from "@prisma/extension-accelerate";
+
+const prisma = new PrismaClient().$extends(withAccelerate());
+```
+### 4. Query your database
