 ## Goals for a base image
 
 Occasionally there are opportunities where alternative standard libc implementations ([musl][musl]/[uclibc][uclibc]) won't do, like in the case of [proprietary](http://i.imgur.com/V5K7N1I.jpg) software like [Plex Media Server](https://www.plex.tv/downloads/) where only pre-compiled binaries are provided which were built against the common glibc library.
 
-(_If your use-case doesn't require glibc and you can compile the program from source, we strongly recommend you use the [Alpine Linux](https://hub.docker.com/\_/alpine) image, based on musl, which is smaller and features a full packaging system_)
