+# Rebuild your next project incrementally.
+
+Create builds incrementally without stopping your server.
+
+## Requirements
+
+There are a few requirements to get this to work
+
+### Update your `next-config.js` file
+
+You need to update the distribution directory in your `next-config.js`. Like this:
+
+```javascript
+import type { NextConfig } from "next";
+import grabDist from "@moduletrace/buncid/dist/rebuilds/next-js/grabDist";
+
+const distDir = grabDist();
+
+const nextConfig: NextConfig = {
+    /* config options here */
+    reactStrictMode: true,
+    distDir,
+};
+
+export default nextConfig;
+```
+
+That's it. This dynamically handles your distribution directory for both `dev` and `start` scripts. Your `development` environment uses the `.next` directory, while your `production` environment uses the `.dist` directory.
