-### 2. Create GraphQL API with [`graphcool`](https://www.npmjs.com/package/graphcool)
-
-If you haven't already, install the Graphcool CLI:
+### 2. Deploy the Prisma database service
 
 ```sh
-# Install Graphcool CLI
-npm install -g graphcool
+cd server
+prisma deploy
+```
+
+> You can use the `prisma` CLI without having it globally installed because it's listed as a _development dependency_ in `package.json`.
+
+When prompted where (i.e. to which _cluster_) you want to deploy your service, choose any of the public clusters, e.g. `public-us1` or `public-eu1`. (If you have Docker installed, you can also deploy locally.)
+
+### 3. Set the Prisma service endpoint
+
+From the output of the previous command, copy the `HTTP` endpoint and paste it into `src/index.js` where it's used to instantiate the `Prisma` binding. You need to replace the current placeholder `__PRISMA_ENDPOINT`:
+
+```js
+const server = new GraphQLServer({
+  typeDefs: './src/schema.graphql',
+  resolvers,
+  context: req => ({
+    ...req,
+    db: new Prisma({
+      typeDefs: 'src/generated/prisma.graphql',
+      endpoint: "__PRISMA_ENDPOINT__",
+      secret: 'mysecret123',
+    }),
+  }),
+})
 ```
 
-Once it's installed, you can start the GraphQL server:
+For example:
+
+```js
+const server = new GraphQLServer({
+  typeDefs: './src/schema.graphql',
+  resolvers,
+  context: req => ({
+    ...req,
+    db: new Prisma({
+      typeDefs: 'src/generated/prisma.graphql',
+      endpoint: "https://eu1.prisma.sh/public-hillcloak-flier-942261/hackernews-graphql-js/dev",
+      secret: 'mysecret123',
+    }),
+  }),
+})
+```
+
+Note that the part `public-hillcloak-flier-952361` of the URL is unique to your service.
+
+### 4. Start the server
+
+To start the server, all you need to do is execute the `start` script by running the following command inside the `server` directory:
 
 ```sh
-cd server
-yarn install
-graphcool deploy
 yarn start
 ```
 
-### 3. Install dependencies & run locally
+### 5. Run the app
+
+Now that the server is running, you can run the app as well:
 
 ```sh
 cd ..
-yarn install
-yarn start # open http://localhost:3000 in your browser
+yarn start
 ```
