## Install
You can build from source:
```sh
go get -u -v github.com/Dreamacro/clash
```
Pre-built binaries are available: [release](https://github.com/Dreamacro/clash/releases)
Requires Go >= 1.10.
## Daemon
Unfortunately, there is no native elegant way to implement golang's daemon.
So we can use third-party daemon tools like pm2, supervisor, and so on.
In the case of [pm2](https://github.com/Unitech/pm2), we can start the daemon this way:
```sh
pm2 start clash
```
If you have Docker installed, you can run clash directly using `docker-compose`.

# fallback select an available policy by priority. The availability is tested by accessing an URL, just like an auto url-test group.
- { name: "fallback-auto", type: fallback, proxies: ["ss1", "ss2", "vmess1"], url: http://www.gstatic.com/generate_204, interval: 300 }
# select is used for selecting proxy or proxy group
# you can use RESTful API to switch proxy, is recommended for use in GUI.
