## Update Guide
### Deploying with Docker Compose:
1. Get the latest code from the main branch:
```shell
git checkout main
git pull origin main
```
2. Go to the next step and update to the latest image:
```shell
cd docker
docker-compose up -d
```
### Deploying from Source Code:
1. Stop API server, Worker and Web frontend Server.
2. Get the latest code from the main branch:
```shell
git checkout main
git pull origin main
```
3. Then, let's run the migration script:
```shell
cd api
flask db upgrade
```
**Note**: To use TTS, `ffmpeg` installation is required on servers running Dify API from source. More details can be found in our [FAQ](https://docs.dify.ai/getting-started/install-self-hosted/install-faq#id-14.-what-to-do-if-this-error-occurs-in-text-to-speech).
