+4. **How to Obtain a GitHub Personal Access Token**
 
+- To use Scrum Helper with authenticated requests (for higher rate limits and private repositories), you need a GitHub personal access token.
+
+  #### Steps to Generate a Token
+
+  1. **Go to GitHub Developer Settings:**  
+    Visit [https://github.com/settings/tokens](https://github.com/settings/tokens) while logged in to your GitHub account.
+
+  2. **Choose Token Type:**  
+    - Select **"Personal access tokens (classic)"**.
+
+  3. **Generate a New Token:**  
+    - Click **"Generate new token"**.
+    - Give your token a descriptive name (e.g., "Scrum Helper Extension").
+    - Set an expiration date if desired.
+
+  4. **Create and Copy the Token:**  
+    - Click **"Generate token"** at the bottom.
+    - **Copy the token** and save it securely. You will not be able to see it again!
+
+  5. **Paste the Token in Scrum Helper:**  
+    - Open the Scrum Helper extension popup.
+    - Paste your token into the "GitHub Token" field.
+
+  > **Keep your token secret!** Never share it or commit it to public repositories.
+
+  **Why use a token?**  
+  GitHub tokens allow the extension to make authenticated requests, increasing your API rate limit and enabling access to private repositories if you grant those permissions.
