 ## Configuration
 Like most suckless-like software, configuration is done through `src/config.def.h` modify it to your heart's content. dwl-bar is compatible with [someblocks](https://sr.ht/~raphi/someblocks/) for status.
 
+If you want dwl-bar to control dwl (via mouse usage primarily) you may want to apply the `patches/dwl-bar-ipc-1.0.diff` patch. 
+**However do note that you will also need to apply the [bar-ipc](https://github.com/djpohly/dwl/wiki/bar-ipc) patch for dwl.**

+For more information about patching see the [hacking](https://suckless.org/hacking/) article from suckless.

 ## Thanks
 Thanks to raphi for somebar this project is largely just somebar but in C and a few tweaks to make it similar to dwm. The ipc protocol is also just the ipc patch in somebar's `contrib/`.
