 Generate Nginx routes configuration file for Next.js static HMTL export.
 
+This [NPM package](https://www.npmjs.com/package/next-nginx-routes) allows you to convert Next.js routes like:
+
+```json
+{
+  "page": "/[foo]",
+  "regex": "^/([^/]+?)(?:/)?$",
+  "routeKeys": { "foo": "foo" },
+  "namedRegex": "^/(?<foo>[^/]+?)(?:/)?$"
+}
+```
+
+... into Nginx routes like:
+
+```nginx
+location ~ ^/([^/]+?)(?:/)?$ {
+  try_files /[foo].html /index.html;
+}
+```
