Community members have helped building Harbor's docker images. If you want to save time from building Harbor from source. You can follow the below instructions to quickly pull Harbor's pre-built images for installation.
The script `docker-compose.sh` is used to change the registry service to pull pre-built images from. It updates `docker-compose.yml` to skip building the images from source locally.
### Steps
Run the command update_compose.sh :
```
$ ./update_compose.sh
Please enter the registry service you want to pull the pre-built images from.
Enter 1 for Docker Hub.
Enter 2 for Daocloud.io (recommended for Chinese users).
or enter other registry URL such as https://my_registry/harbor/ .
The default is 1 (Docker Hub):
```
Enter **1** to pull images from Docker Hub,
Enter **2** to pull image from Daocloud.io, recommended for Chinese users.
or Enter other registry URL like `https://my_registry/harbor/` . Do not forget the "/" and the end.
This command will back up and update the file `Deploy/docker-compose.yml` . Next, just follow the [Harbor Installation Guide](../../docs/installation_guide.md) to install Harbor.
