 ## Build and Run
 
-If you are running an Ubuntu or Debian docker host, you should be able to `docker-compose up` and it should just work.

-If you are running an RPM based distro, check out Binan/rtpengine-docker which is tested on Fedora.
+If you are running an Ubuntu, Debian, Centos, or Fedora docker host, you should be able to `docker-compose up` and it should just work.
 
 If you are running any other linux flavor as your docker host, this repository is not going to work for you as-is.

 Whatever the `uname -r` is at "build" time, the kernel version headers and kernel module for whatever docker host was used to build this image will try and use that version.
 
-The `FROM` line of the `Dockerfile` in this project is `ubuntu:14.04`, which means that any build host that is not also Ubuntu 14.04 will silently skip including that as part of the docker build (see the "`|| true`" in the `Dockerfile` for that step).

 All this is really doing is pre-building a kernel module for you to use at docker run time. This is a time-saver, but is not necessary.
 
 ## At run time
 
-Regardless of the linux docker host flavor you _build_ this on, you should still be able to _run_ this on any Ubuntu or Debian flavor derivative host version, and it should properly build the DKMS kernel before loading it and running the rtpengine daemon. This does take a little time.
