+# 🔉📃 Summarize Audio with Deepgram
+
+A NodeJS Cloud Function for summarizing audio number using [Deepgram API](https://deepgram.com/).
+
+_Example input:_
+
+```json
+{
+  "fileUrl": "https://static.deepgram.com/examples/interview_speech-analytics.wav"
+}
+```
+
+_Example output:_
+
+```json
+
+```
+
+## 📝 Environment Variables
+
+List of environment variables used by this cloud function:
+
+- **DEEPGRAM_API_KEY** - Deepgram API Key
+
+ℹ️ _Create your Deepgram API key at console.deepgram.com_
+
+## 🚀 Deployment
+
+1. Clone this repository, and enter this function folder:
+
+```bash
+git clone https://github.com/open-runtimes/examples.git && cd examples
+cd node/deepgram_audio_summary
+```
+
+2. Enter this function folder and build the code:
+
+```bash
+docker run --rm --interactive --tty --volume $PWD:/usr/code openruntimes/node:v2-18.0 sh /usr/local/src/build.sh
+```
+
+As a result, a `code.tar.gz` file will be generated.
+
+3. Start the Open Runtime:
+
+```bash
+docker run -p 3000:3000 -e INTERNAL_RUNTIME_ENTRYPOINT=src/index.js -e INTERNAL_RUNTIME_KEY=secret-key --rm --interactive --tty --volume $PWD/code.tar.gz:/tmp/code.tar.gz:ro openruntimes/node:v2-18.0 sh /usr/local/src/start.sh
+```
+
+Your function is now listening on port `3000`, and you can execute it by sending `POST` request with appropriate authorization headers. To learn more about runtime, you can visit NodeJS runtime [README](https://github.com/open-runtimes/open-runtimes/tree/main/runtimes/node-18.0). 
+
+4. Run the cURL function to send request.
+
+```bash
+curl --location --request POST 'http://localhost:3000' --header 'Content-Type: application/json' --header 'X-Internal-Challenge: secret-key' --data-raw '{"variables": {"DEEPGRAM_API_KEY": "YOUR_DEEPGRAM_API_KEY"},"payload": {"fileUrl": "https://static.deepgram.com/examples/interview_speech-analytics.wav"}}'
+```
+
+## 📝 Notes
+
+- This function is designed for use with Appwrite Cloud Functions. You can learn more about it in [Appwrite docs](https://appwrite.io/docs/functions).
+- This example is compatible with NodeJS 18.0. Other versions may work but are not guarenteed to work as they haven't been tested.
