+## Getting your Trello API key and token
+
+Before you can import your Trello boards, you need to get your Trello API key and token. Follow these steps (only takes a couple of minutes):
+
+1. **Sign in to your Trello account**  
+   Go to [https://trello.com](https://trello.com) and log in with your Trello account.
+
+2. **Create a new integration**  
+   Visit [https://trello.com/power-ups/admin](https://trello.com/power-ups/admin). Click **Create new** and fill in the following details:
+
+   - **Name**: Choose a name for your integration (e.g. "Kan Import")
+   - **Workspace**: Select the workspace containing the boards you want to import
+   - **Email**: Enter your email address
+   - **Support email**: Enter your email address
+   - **Author**: Add your name
+
+3. **Get a Trello API Key**  
+   Now click **Generate a new API key** to create an API key.
+
+4. **Generate a Trello Token**  
+   On the same page (to the right of the API key), click the link to **generate a Token**. Approve the permissions and copy your token (make sure to save it somewhere secure like a password manager).
+
+## Importing your Trello boards
+
+Once you have your API key and token, importing your Trello boards is easy. Follow these steps:
+
+1. **Create a new import in Kan**  
+   Navigate to **[https://kan.bn/boards](https://kan.dev/boards)** and click **Import**.
+
+2. **Select Trello as the Import Source**  
+   Choose **Trello** from the list of import options and click **Select source**.
+
+3. **Enter Your Trello API Key and Token**  
+   Paste your API key and token into the provided fields and click **Fetch boards** (don't worry, we don't store your key or token).
+
+4. **Start the Import**  
+   Select the board you want to import and click **Import boards**. Once the import is complete, you'll see your boards in Kan.
