-It's also very easy to build from source:
-
-```
-git clone -b 3.0release https://gitee.com/ossrs/srs.git &&
-cd srs/trunk && ./configure && make && ./objs/srs -c conf/srs.conf

-> Note: We use [mirrors(gitee)](#mirrors) here, but it's also ok to `git clone https://github.com/ossrs/srs.git`

-> Remark: Recommend to use Centos7 64bits, please read wiki([CN][v3_CN_Build],[EN][v3_EN_Build]), or use [docker][docker-dev].
