+Here is the [GitHub Action file](https://github.com/meilisearch/documentation/blob/master/.github/workflows/gh-pages-scraping.yml) we use in production for the MeiliSearch documentation.
+
+### About the API Key
+
+The API key you must provide as environment variable should have the permissions to add documents into your MeiliSearch instance.
+
+Thus, you need to provide the private key or the master key.

+## Configuration file
+
+A generic configuration file:
+
+```json
+{
+  "index_uid": "docs",
+  "start_urls": ["https://www.example.com/doc/"],
+  "sitemap_urls": ["https://www.example.com/sitemap.xml"],
+  "stop_urls": [],
+  "selectors": {
+    "lvl0": {
+      "selector": ".docs-lvl0",
+      "global": true,
+      "default_value": "Documentation"
+    },
+    "lvl1": {
+      "selector": ".docs-lvl1",
+      "global": true,
+      "default_value": "Chapter"
+    },
+    "lvl2": ".docs-content .docs-lvl2",
+    "lvl3": ".docs-content .docs-lvl3",
+    "lvl4": ".docs-content .docs-lvl4",
+    "lvl5": ".docs-content .docs-lvl5",
+    "lvl6": ".docs-content .docs-lvl6",
+    "text": ".docs-content p, .docs-content li"
+  }
+}
+```
+
+The scraper will focus on the highlighted information depending on your selectors.
