Clear operational characteristics of attention however make study of this crucial brain function accessible to any animal model. Whereas earlier approaches have relied on freely behaving paradigms placed in an ecologically relevant context, recent tethered preparations have focused on brain imaging and electrophysiology in virtual reality environments. Insight into brain activity during attention-like behavior has revealed key elements of attention in the insect brain. Surprisingly, a variety of brain structures appear to be involved, suggesting that even in the smallest brains attention might involve widespread coordination of neural activity.},

 - `bib_by_default` - Automatically append the `bib_command` at the end of every markdown document, defaults to `true`
 - `full_bib_command` - The syntax to render your entire bibliography, defaults to `\full_bibliography`
 - `csl_file` - The path or url to a bibtex CSL file, specifying your citation format. Defaults to `None`, which renders in a plain format. A registry of citation styles can be found here: https://github.com/citation-style-language/styles

 ## Usage

-1. Add your citations as you would if you used pandoc, IE: `[@first_cite;@second_cite]`
+1. Add your citations as you would if you used pandoc, IE: `[@first_cite;@second_cite]`.
 2. Add `\bibliography`, or the value of `bib_command`, to the doc you want your references rendered (if `bib_by_default` is set to true this is automatically applied for every page).
 3. (Optional) Add `\full_bibliography`, or the value of `full_bib_command`, to where you want the full bibliography rendered. *Note*: This is currently not working properly, since this plugin can't dictate the order in which files are processed. The best way to ensure the file with the full bibliography gets processed last is to use numbers in front of file/folder names to enforce the order of processing, IE: `01_my_first_file.md`

+4. (Optional) Configure the `csl_file` option to dictate the citation text formatting. This plugin automatically detects if the citation is an inline style and inserts that text when appropriate.
 
 ## Debugging
