 ### Pipeline Different Objects
 
 (Please note, this section is still in progress)
 
 "finder":
+
 - executable: rg, git ls-files, ...
 - things in lua already
 - vim things
 
 "picker":
+
 - fzf
 - sk
 - does this always need to be fuzzy?
   - you'll map what you want to do with vimscript / lua mappings
 
 "previewer":
+
 - sometimes built-in
 - sometimes a lua callback
 
-
 As an example, you could pipe your inputs into fzf, and then it can sort them for you.
 
 fzf:
+
 - have a list of inputs
 - i have a prompt/things people typed
 - instantly return the stuff via stdout
