+# Setting up Transcoding Binaries
+
+## About Transcoding
+Transcoders are used by Libresonic to convert media from their on disk format
+to a format that can be consumed by clients. This is done not only for compatibility
+but also to save bandwidth when dealing with heavier file types. For example, although your
+library might use the flac format, bandwidth can be saved by converting to mp3 before 
+transmission.
+
+## Bare Minimum setup (Linux)
+
+*Commands provided below are illustrative*
+
+Install ffmpeg using your distributions package manager. 
+
+```
+sudo yum install ffmpeg
+```
+
+In the case that ffmpeg is not available, you have two options.
+- Add a repository that provides ffmpeg
+- Build the binary from source
+  - Outdated documentation for this can be found at [TRANSCODE.TXT](documentation/developer/TRANSCODE.TXT)
+
+Create a `transcode` directory within your `libresonic.home` directory:
+
+```
+mkdir /var/libresonic/transcode
+```
+
+Ensure it has the correct permissions:
+
+```
+-bash-4.2$ ls -alhd transcode/
+drwxr-xr-x. 2 tomcat tomcat 41 Jan  7 13:45 transcode/
+```
+
+Within the `transcode` directory symlink to ffmpeg and verify correct permissions
+```
+-bash-4.2$ cd transcode/
+-bash-4.2$ ln -s /usr/bin/ffmpeg
+-bash-4.2$ ls -alh
+total 4.0K
+drwxr-xr-x. 2 tomcat tomcat   41 Jan  7 13:45 .
+drwxr--r--. 7 tomcat tomcat 4.0K Feb 23 19:23 ..
+lrwxrwxrwx. 1 tomcat tomcat   15 Jan  7 13:45 ffmpeg -> /usr/bin/ffmpeg
+```
