-## Usage
+### Full Installation Guide
+#### Export Wifi Credentials and OpenAI API Key
+You need to export your Wifi credentials and OpenAI API Key as environment variables. This is required for the SDK to connect to the internet and access OpenAI services.
+
+```bash
+export WIFI_SSID="your_wifi_ssid"
+export WIFI_PASSWORD="your_wifi_password"
+export OPENAI_API_KEY="your_openai_api_key"
+```
+
+#### Install correct version of ESP-IDF
+```bash
+mkdir ~/esp
+cd ~/esp
+git clone -b release/v5.5 https://github.com/espressif/esp-idf.git esp-idf-v5.5.0
+cd esp-idf-v5.5.0
+./install.sh
+chmod 777 ./export.sh
+./export.sh 
+```
+
+#### Test IDF
+`idf.py --version`
+The above didn't work for me so I included this line in ~/.bashrc and reloaded the terminal: `. $HOME/esp/esp-idf-v5.5.0/export.sh`
+
+#### Clone repo including dependencies
+```bash
+git clone --recursive https://github.com/DFRobot/openai-realtime-embedded-sdk.git
+cd openai-realtime-embedded-sdk
+```
