+
+### Post Installation
+
+Make sure that you have filetype plugins enabled, as the plugin makes use of **|commentstring|** where possible (which is usually set in a filetype plugin). See **|filetype-plugin-on|** for details, but the short version is make sure this line appears in your vimrc:
+
+```sh
+filetype plugin on
+```
+
+## Usage
+
+### Documentation
+
+Please see the vim help system for full documentation of all options: `:help nerdcommenter`
+
+### Settings
+
+Several settings can be added to your vimrc to change the default behavior. Some examples:
+
+```vim
+" Add spaces after comment delimiters by default
+let g:NERDSpaceDelims = 1
+
+" Use compact syntax for prettified multi-line comments
+let g:NERDCompactSexyComs = 1
+
+" Align line-wise comment delimiters flush left instead of following code indentation
+let g:NERDDefaultAlign = 'left'
+
+" Set a language to use its alternate delimiters by default
+let g:NERDAltDelims_java = 1
+
+" Add your own custom formats or override the defaults
+let g:NERDCustomDelimiters = { 'c': { 'left': '/**','right': '*/' } }
+
+" Allow commenting and inverting empty lines (useful when commenting a region)
+let g:NERDCommentEmptyLines = 1
+
+" Enable trimming of trailing whitespace when uncommenting
+let g:NERDTrimTrailingWhitespace = 1
+
+" Enable NERDCommenterToggle to check all selected lines is commented or not 
+let g:NERDToggleCheckAllLines = 1
+```
+
+### Default mappings
+
+The following key mappings are provided by default (there is also a menu provided that contains menu items corresponding to all the below mappings):
+
+Most of the following mappings are for normal/visual mode only. The **|NERDComInsertComment|** mapping is for insert mode only.
+
+  * `[count]<leader>cc` **|NERDComComment|**
+
+    Comment out the current line or text selected in visual mode.
+
+  * `[count]<leader>cn` **|NERDComNestedComment|**
+
+    Same as <leader>cc but forces nesting.
+
+  * `[count]<leader>c<space>` **|NERDComToggleComment|**
+
+    Toggles the comment state of the selected line(s). If the topmost selected line is commented, all selected lines are uncommented and vice versa.
+
+  * `[count]<leader>cm` **|NERDComMinimalComment|**
+
+    Comments the given lines using only one set of multipart delimiters.
+
+  * `[count]<leader>ci` **|NERDComInvertComment|**
+
+    Toggles the comment state of the selected line(s) individually.
+
+  * `[count]<leader>cs` **|NERDComSexyComment|**
+
+    Comments out the selected lines with a pretty block formatted layout.
+
+  * `[count]<leader>cy` **|NERDComYankComment|**
+
+    Same as <leader>cc except that the commented line(s) are yanked first.
+
+  * `<leader>c$` **|NERDComEOLComment|**
+
+    Comments the current line from the cursor to the end of line.
+
+  * `<leader>cA` **|NERDComAppendComment|**
+
+    Adds comment delimiters to the end of line and goes into insert mode between them.
+
+  * **|NERDComInsertComment|**
+
+    Adds comment delimiters at the current cursor position and inserts between. Disabled by default.
+
+  * `<leader>ca` **|NERDComAltDelim|**
+
+    Switches to the alternative set of delimiters.
+
+  * `[count]<leader>cl`  
+    `[count]<leader>cb` **|NERDComAlignedComment|**
+
+    Same as **|NERDComComment|** except that the delimiters are aligned down the left side (`<leader>cl`) or both sides (`<leader>cb`).
+
+  * `[count]<leader>cu` **|NERDComUncommentLine|**
+
+    Uncomments the selected line(s).
