+## Build
+
+* `go build`
+* Alternatively, you can grab the latest nightly from Circle CI by logging into Circle CI or adding `#artifacts` at the end of URL like such: https://circleci.com/gh/shadowsocks/v2ray-plugin/20#artifacts
+
+## Usage
+
+See command line args for advanced usages.
+
+### Shadowsocks over websocket (HTTP)
+
+On your server
+
+```sh
+ss-server -c config.json -p 80 --plugin v2ray-plugin --plugin-opts "server"
+```
+
+On your client
+
+```sh
+ss-local -c config.json -p 80 --plugin v2ray-plugin
+```
+
+### Shadowsocks over websocket (HTTPS)
+
+On your server
+
+```sh
+ss-server -c config.json -p 443 --plugin v2ray-plugin --plugin-opts "server;tls;host=mydomain.me"
+```
+
+On your client
+
+```sh
+ss-local -c config.json -p 443 --plugin v2ray-plugin --plugin-opts "tls;host=mydomain.me"
+```
+
+### Shadowsocks over quic
+
+On your server
+
+```sh
+ss-server -c config.json -p 443 --plugin v2ray-plugin --plugin-opts "server;mode=quic;host=mydomain.me"
+```
+
+On your client
+
+```sh
+ss-local -c config.json -p 443 --plugin v2ray-plugin --plugin-opts "mode=quic;host=mydomain.me"
+```
+
+### Issue a cert for TLS and QUIC
+
+v2ray-plugin will look for TLS certificates signed by [acme.sh](https://github.com/Neilpang/acme.sh) by default.
+Here's some sample commands for issuing a certificate using CloudFlare.
+You can find commands for issuing certificates for other DNS providers at acme.sh.
+
+```sh
+curl https://get.acme.sh | sh
+~/.acme.sh/acme.sh --issue --dns dns_cf -d mydomain.me
+```
+
+Alternatively, you can specify path to your certificates using option `cert` and `key`.
