+## How to use
+
+After installation, you can add tagsinput as custom field.
+
+#### Suggestions for tag
+
+While adding tagsInput, you will see `API URL` field.
+
+If you want to use REST API for suggestions, then add your API url in this field.
+
+**Notes:**
+
+- If API domain is different, then full API URL is required. i.e `http://localhost:1337/api/v1/tags?fields[0]=name` (Make sure API CORS are enabled for your strapi domain in this case).
+- Otherwise add only path of API i.e `/api/v1/tags?fields[0]=name`
+- API response should contain `name` field.
+  For example,
+
+  ```
+    [
+        { name: "tag1" },
+        { name: "tag2" }
+    ]
+  ```
