 # dwmblocks
-Modular status bar for dwm written in c.
-# modifying blocks
-The statusbar is made from text output from commandline programs.
-Blocks are added and removed by editing the blocks.h header file.
-# Luke's bulid
-I have dwmblocks read my preexisting scripts [here in my dotfiles repo](https://github.com/LukeSmithxyz/voidrice/tree/master/.local/bin/statusbar).
-So if you want my build out of the box, download those and put them in your `$PATH`.
-I do this to avoid redundancy in LARBS, both i3 and dwm use the same statusbar scripts.
-# signalling changes
-For example, the audio module has the update signal 10 by default.
-Thus, running `pkill -RTMIN+10 dwmblocks` will update it.
-# clickable modules
-Like i3blocks, this build allows you to build in additional actions into your scripts in response to click events.
-See the above linked scripts for examples of this using the `$BLOCK_BUTTON` variable.
 
-For this feature to work, you need the appropriate patch in dwm as well. See [here](https://gist.github.com/danbyl/54f7c1d57fc6507242a95b71c3d8fdea).
+Modular status bar for dwm written in c.
+
+# Modifying blocks
+
+The statusbar is made from text output from commandline programs.  Blocks are
+added and removed by editing the config.h file.
+
+# Luke's build
+
+I have dwmblocks read my preexisting scripts
+[here in my dotfiles repo](https://github.com/LukeSmithxyz/voidrice/tree/master/.local/bin/statusbar).
+So if you want my build out of the box, download those and put them in your
+`$PATH`. I do this to avoid redundancy in LARBS, both i3 and dwm use the same
+statusbar scripts.
+
+# Signalling changes
+
+Most statusbars constantly rerun every script every several seconds to update.
+This is an option here, but a superior choice is giving your module a signal
+that you can signal to it to update on a relevant event, rather than having it
+rerun idly.
+
+For example, the audio module has the update signal 10 by default.  Thus,
+running `pkill -RTMIN+10 dwmblocks` will update it.
+
+You can also run `kill -44 $(pidof dwmblocks)` which will have the same effect,
+but is faster.  Just add 34 to your typical signal number.
+
+My volume module *never* updates on its own, instead I have this command run
+along side my volume shortcuts in dwm to only update it when relevant.
+
+Note that if you signal an unexpected signal to dwmblocks, it will probably
+crash. So if you disable a module, remember to also disable any cronjobs or
+other scripts that might signal to that module.
+
+# Clickable modules
+
+Like i3blocks, this build allows you to build in additional actions into your
+scripts in response to click events.  See the above linked scripts for examples
+of this using the `$BLOCK_BUTTON` variable.
+
+For this feature to work, you need the appropriate patch in dwm as well. See
+[here](https://gist.github.com/danbyl/54f7c1d57fc6507242a95b71c3d8fdea).
