 ## Customizing bb
 `bb` comes with a bunch of pre-defined bindings for basic actions in
 [config.def.h](config.def.h) (within `bb`, press `?` to see descriptions of the
 bindings), but it's very easy to add new bindings for whatever custom scripts
 you want to run, just add a new entry in `bindings` in config.h with the form

 ### Fuzzy Finding
 To select from a list of options with a fuzzy finder in a binding, you can use
 the `PICK` macro. During the `make` process, you can use `PICKER=fzy`,
 `PICKER=fzf`, `PICKER=dmenu`, or `PICKER=ask` to choose which fuzzy finder

 ### API
 `bb` also exposes an API that allows shell scripts to modify `bb`'s internal
