# dwmblocks
Modular status bar for dwm written in c.
+# usage
+To use dwmblocks first run 'make' and then install it with 'sudo make install'.
+After that you can put dwmblocks in your xinitrc or other startup script to have it start with dwm.
# modifying blocks
The statusbar is made from text output from commandline programs.
Blocks are added and removed by editing the blocks.h header file.
+By default the blocks.h header file is created the first time you run make which copies the default config from blocks.def.h.
+This is so you can edit your status bar commands and they will not get overwritten in a future update.
