## 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`.

## Config
Configuration file at `$HOME/.config/clash/config.ini`
Below is a simple demo configuration file:
```ini
[General]
port = 7890
socks-port = 7891
# redir proxy for Linux and macOS
redir-port = 7892
# A RESTful API for clash
external-controller = 127.0.0.1:8080
[Proxy]
# name = ss, server, port, cipher, password
# The types of cipher are consistent with go-shadowsocks2
# support AEAD_AES_128_GCM AEAD_AES_192_GCM AEAD_AES_256_GCM AEAD_CHACHA20_POLY1305 AES-128-CTR AES-192-CTR AES-256-CTR AES-128-CFB AES-192-CFB AES-256-CFB CHACHA20-IETF XCHACHA20
ss1 = ss, server1, port, AEAD_CHACHA20_POLY1305, password
ss2 = ss, server2, port, AEAD_CHACHA20_POLY1305, password
# name = socks5, server, port
socks = socks5, server1, port
[Proxy Group]
# url-test select which proxy will be used by benchmarking speed to a URL.
# name = url-test, [proxies], url, interval(second)
auto = url-test, ss1, ss2, http://www.google.com/generate_204, 300
# select is used for selecting proxy or proxy group
# you can use RESTful API to switch proxy, is recommended for use in GUI.
# name = select, [proxies]
Proxy = select, ss1, ss2, auto
