-redis-ipc is an example of how redis_ can be used as an advanced IPC
-mechanism on an embedded Linux system, for instance as a substitute for the
-more common choice of dbus.
+redis-ipc (the concept) comes in 2 flavors, a python module (this repo)
+and a lightweight C library implementation. See the (original)
+`redis-ipc C library`_ repo for a more detailed description.
 
-redis-ipc is intended to make communication among different logical components
-of a system convenient. It is not intended to replace shared memory for high
-data-rate transfers between processes, where lowest possible overhead is key,
-but to provide a convenient and reliable way to implement the following
