+==== NerdTree ====
+NerdTree is one of my most used plugins. It is fantastic at navigating files,
+along with moving and deleting them. There are a bunch of really useful
+key mappings that I forget from time to time. Just remember to press ? in an open
+NerdTree buffer and you'll get all the shortcuts to refresh yourself with.
 ==== YCM ====
 YCM uses a python script to tell it what to do in terms of syntax highlighting and
 error/warning display. You have to tell it where to use this script by adding this in
-the .vimrc file:
+the ''%%.vimrc%%'' file:
-    let g:ycm_global_ycm_extra_conf = '~/.vim/.ycm_extra_conf.py'

 You can also style the line that has the warning/error with these groups:
-*YcmErrorLine*, which falls back to group SyntasticErrorLine if it exists
+''%%YcmErrorLine%%'' which falls back to group SyntasticErrorLine if it exists
-*YcmWarningLine*, which falls back to group SyntasticWarningLine if it exists
+''%%YcmWarningLine%%'' which falls back to group SyntasticWarningLine if it exists
 Note that the line highlighting groups only work when gutter signs are turned on.
 The syntax groups used to highlight regions of text with errors/warnings:
-*YcmErrorSection*, which falls back to group SyntasticError if it exists and then SpellBad
