 ## 🚀 TL;DR
+1. Make sure your OpenAI API key is exported with:
+```bash
+echo "export OPENAI_API_KEY='your_openai_api_key_here'" >> ~/.bashrc && source ~/.bashrc
+```
+2. Run the setup script with the `--no-build` flag to pull the latest image from DockerHub:
 ```bash
-echo "export OPENAI_API_KEY='your_openai_api_key_here'" >> ~/.bashrc
-source ~/.bashrc
 curl -s https://raw.githubusercontent.com/judahpaul16/gpt-home/main/contrib/setup.sh | \
     bash -s -- --no-build
 ```

 ### ⚠️ Caution: Battery Connection
-**IMPORTANT**: The image on the left is for illustration purposes. ***Do not connect the battery directly to the Raspberry Pi. Use a UPS or power supply with a battery like this [one](https://a.co/d/1rMMCPR).*** Connecting the battery directly to the Raspberry Pi can cause damage to the board from voltage fluctuations.

 Before connecting the battery, ensure that the polarity is correct to avoid damage to your Raspberry Pi or other components. Disconnect power sources before making changes.
