+#### 👥 Populate
+
+Content-types in Strapi may have relationships with other content-types. To ensure that these links are fetched and added to an entry correctly from your Strapi database, the correct populate rule must be provided ([see documentation](https://docs-next.strapi.io/developer-docs/latest/developer-resources/database-apis-reference/entity-service/populate.html#basic-populating)).
+
+To communicate the populate rule, use the `populate` setting on the according content-type in the plugin's settings.
+
+**For example**
+
+Imagine my `restaurant` content-type has a relation with a repeatable-component `repeatableComponent` that itself has a relationship with the content-type `categories`.
+
+The following population will ensure that a `restaurant` entry contains even the most nested.
+
+```js
+module.exports = {
+  meilisearch: {
+    config: {
+      restaurant: {
+        populate: ['repeatableComponent.categories', 'categories'],
+      }
+    }
+  },
+}
+```
+
+by provinding this, the following is indexed in Meilisearch:
+
+```json
+  {
+    "id": "restaurant-1",
+    "title": "The slimmy snail",
+    // ... other restaurant fields
+    "repeatableComponent": [
+      {
+        "id": 1,
+        "title": "my repeatable component 1"
+        "categories": [
+          {
+            "id": 3,
+            "name": "Asian",
+            // ... other category fields
+          },
+          {
+            "id": 2,
+            "name": "Healthy",
+            // ... other category fields
+          }
+        ],
+
+      }
+    ],
+
+  }
+```

 ### 🕵️‍♀️ Start Searching <!-- omit in toc -->
 
 Once you have a content-type indexed in Meilisearch, you can [start searching](https://docs.meilisearch.com/learn/getting_started/quick_start.html#search).
