+[Vim](www.vim.org)
+(Vi IMproved) is a clone of the popular vi editor for Unix. It is a a text
+editor designed for speed and increased productivity, and is ubiquitous in most
+unix-based systems. It has numerous keybindings for speedy navigation to
+specific points in the file, and for fast editing.
+
+## Basics of navigating Vim
+
+```
+ vim <filename> # Open <filename> in vim
+ :q # Quit vim
+ :w # Save current file
+ :wq # Save file and quit vim
+ :q! # Quit vim without saving file
+ # ! *forces* :q to execute, hence quiting vim without saving
+ :x # Save file and quit vim, shorter version of :wq
+
+ u # Undo
+ CTRL+R # Redo
+
+ h # Move left one character
+ j # Move down one line
+ k # Move up one line
+ l # Move right one character
+
+ # Moving within the line
+
+ 0 # Move to beginning of line
+ $ # Move to end of line
+ ^ # Move to first non-blank character in line
+
+ # Searching in the text
+
+ /word # Highlights all occurences of word after cursor
+ ?word # Highlights all occurences of word before cursor
+ n # Moves cursor to next occurence of word after search
+ N # Moves cursor to previous occerence of word
+
+ :%s/foo/bar/g # Change 'foo' to 'bar' on every line in the file
+ :s/foo/bar/g # Change 'foo' to 'bar' on the current line
+
+ # Jumping to characters
+
+ f<character> # Jump forward and land on <character>
+ t<character> # Jump forward and land right before <character>
+
+ # For example,
+ f< # Jump forward and land on <
+ t< # Jump forward and land right before <
+
+ # Moving by word
+
+ w # Move forward by one word
+ b # Move back by one word
+ e # Move to end of current word
+
+ # Other characters for moving around
+
+ gg # Go to the top of the file
+ G # Go to the bottom of the file
+ :NUM # Go to line number NUM (NUM is any number)
+ H # Move to the top of the screen
+ M # Move to the middle of the screen
+ L # Move to the bottom of the screen
+```
+
+## Modes:
+
+Vim is based on the concept on **modes**.
+
+Command Mode - vim starts up in this mode, used to navigate and write commands
+Insert Mode - used to make changes in your file
+Visual Mode - used to highlight text and do operations to them
+Ex Mode - used to drop down to the bottom with the ':' prompt to enter commands
+
+```
+ i # Puts vim into insert mode, before the cursor position
+ a # Puts vim into insert mode, after the cursor position
+ v # Puts vim into visual mode
+ : # Puts vim into ex mode
+ <esc> # 'Escapes' from whichever mode you're in, into Command mode
+
+ # Copying and pasting text
+
+ y # Yank whatever is selected
+ yy # Yank the current line
+ d # Delete whatever is selected
+ dd # Delete the current line
+ p # Paste the copied text after the current cursor position
+ P # Paste the copied text before the current cursor position
+ x # Deleting character under current cursor position
+```
+
+## The 'Grammar' of vim
+
+Vim can be thought of as a set of commands in a
+'Verb-Modifier-Noun' format, where:
+
+Verb - your action
+Modifier - how you're doing your action
+Noun - the object on which your action acts on
+
+A few important examples of 'Verbs, 'Modifiers', and 'Nouns':
+
+```
+ # 'Verbs'
+
+ d # Delete
+ c # Change
+ y # Yank (copy)
+ v # Visually select
+
+ # 'Modifiers'
+
+ i # Inside
+ a # Around
+ NUM # Number (NUM is any number)
+ f # Searches for something and lands on it
+ t # Searches for something and stops before it
+ / # Finds a string from cursor onwards
+ ? # Finds a string before cursor
+
+ # 'Nouns'
+
+ w # Word
+ s # Sentence
+ p # Paragraph
+ b # Block
+
+ # Sample 'sentences' or commands
+
+ d2w # Delete 2 words
+ cis # Change inside sentence
+ yip # Yank inside paragraph (copy the para you're in)
+ ct< # Change to open bracket
+ # Change the text from where you are to the next open bracket
+ d$ # Delete till end of line
+```
+
+## Some shortcuts and tricks
+
+ <!--TODO: Add more!-->
+```
+ > # Indent selection by one block
+ < # Dedent selection by one block
+ :earlier 15m # Reverts the document back to how it was 15 minutes ago
+ :later 15m # Reverse above command
+ ddp # Swap position of consecutive lines, dd then p
+ . # Repeat previous action
+```
+
+## Macros
+
+Macros are basically recordable actions.
+When you start recording a macro, it records **every** action and command
+you use, until you stop recording. On invoking a macro, it applies the exact
+same sequence of actions and commands again on the text selection.
+
+```
+ qa # Start recording a macro named 'a'
+ q # Stop recording
+ @a # Play back the macro
+```
+
+### Configuring ~/.vimrc
+
+The .vimrc file can be used to configure Vim on startup.
+
+Here's a sample ~/.vimrc file:
+
+```
+" Example ~/.vimrc
+" 2015.10
+
+" Required for vim to be iMproved
+set nocompatible
+
+" Determines filetype from name to allow intelligent auto-indenting, etc.
+filetype indent plugin on
+
+" Enable syntax highlighting
+syntax on
+
+" Better command-line completion
+set wildmenu
+
+" Use case insensitive search except when using capital letters
+set ignorecase
+set smartcase
+
+" When opening a new line and no file-specific indenting is enabled,
+" keep same indent as the line you're currently on
+set autoindent
+
+" Display line numbers on the left
+set number
+
+" Indentation options, change according to personal preference
+
+" Number of visual spaces per TAB
+set tabstop=4
+
+" Number of spaces in TAB when editing
+set softtabstop=4
+
+" Number of spaces indented when reindent operations (>> and <<) are used
+set shiftwidth=4
+
+" Convert TABs to spaces
+set expandtab
+
+" Enable intelligent tabbing and spacing for indentation and alignment
+set smarttab
+```
