+# Build directory not writeable
+
+#### Why This Error Occurred
+
+The filesystem does not allow writing to the specified directory. A common cause for this error is starting a [custom server](https://github.com/zeit/next.js#custom-server-and-routing) in development mode on a production server, for example, [now.sh](https://zeit.co) which [doesn't allow you to write to the filesystem after your app is built](https://zeit.co/docs/deployment-types/node#file-system-specifications).
+
+#### Possible Ways to Fix It
+
+When using a custom server with a server file, for example called `server.js`, make sure you update the scripts key in `package.json` to:
+
+```json
+{
+  "scripts": {
+    "dev": "node server.js",
+    "build": "next build",
+    "start": "NODE_ENV=production node server.js"
+  }
+}
+```
+
+and the custom server starts Next in production mode when `NODE_ENV` is `production`
+
+```js
+const dev = process.env.NODE_ENV !== 'production'
+const app = next({ dev })
+```

+# The poweredByHeader has been removed
+
+#### Why This Error Occurred
+
+Starting at Next.js version 5.0.0 the `poweredByHeader` option has been removed.
+
+#### Possible Ways to Fix It
+
+If you still want to remove `x-powered-by` you can use one of the custom-server examples.
+
+And then manually remove the header using `res.removeHeader('x-powered-by')`

+## The idea behind the example
+
+ReactRouter has a convenience property on the `Link` element to allow an author to set the _active_ className on a link. This example replicates that functionality using Next's own `Link`.

+# Pass Server Data Directly to a Next.js Page during SSR
+
+## How to use
+

+
+```bash

+
+## The idea behind the example
+
+If you already have a custom server which has local data (for instance cached data from an API call, or data read
+from a file at startup) that you wish to make available in the Next.js page, you can pass that data in the query
+parameter of `nextApp.render()`.
+
+This is not the only way to pass data. You could also expose an endpoint and make a `fetch()` call to localhost, or you could
+import server-side code with `eval` (necessary to prevent webpack from trying to package your server code). However both
+solutions leave something to be desired in either performance or elegance.
+
+This example shows the express server at `server.js` reading in a file at load time with static data (this could also have been
+data cached from an API call) in `operations/get-item.js`. It has two routes: a home page, and an item page. The item page uses
+data from the get-item operation, passed as a query parameter in `routes/item.js`.
+
+We use this data in `pages/item.js` if rendered server-side, or make a fetch request if rendered client-side.
+The server knows whether or not to use next.js to render the route based on the Accept header, which will be 
+`application/json` when we fetch client-side.
+
+Take a look at the following files:
+
+* server.js
+* routes/item.js
+* pages/item.js
+* operations/get-item.js
