 Usage
 -----
 
-_vim-easy-align_ defines `:EasyAlign` command (and the right-justification
-variant `:EasyAlign!`) in the visual mode.
+### Concept of _alignment rule_
 
-| Mode                      | Command                                       |
-| ------------------------- | --------------------------------------------- |
-| Interactive mode          | `:EasyAlign`                                  |
-| Using predefined rules    | `:EasyAlign [FIELD#] DELIMITER_KEY [OPTIONS]` |
-| Using regular expressions | `:EasyAlign [FIELD#] /REGEXP/ [OPTIONS]`      |
+Though easy-align can align lines of text around any delimiter, it provides
+shortcuts for the most common use cases with the concept of "_alignment rule_".
+
+An *alignment rule* is a predefined set of options for common alignment tasks,
+which is identified by a single character, *DELIMITER KEY*, such as `<Space>`,
+`=`, `:`, `.`, `|`, `&`, `#`, and `,`.
+
+Think of it as a shortcut. Instead of writing regular expression and setting
+several options, you can just type in a single character.
+
+### Execution models
+
+There are two ways to use easy-align.
+
+#### 1. Using `<Plug>` mappings
+
+The recommended method is to use `<Plug>` mappings as described earlier.
+
+| Mapping                 | Mode   | Description                                          |
+| ----------------------- | ------ | ---------------------------------------------------- |
+| `<Plug>(EasyAlign)`     | normal | Start interactive mode for a motion/text object      |
+| `<Plug>(EasyAlign)`     | visual | Start interactive mode for the selection             |
+| `<Plug>(LiveEasyAlign)` | normal | Start live-interactive mode for a motion/text object |
+| `<Plug>(LiveEasyAlign)` | visual | Start live-interactive mode for the selection        |
+
+#### 2. Using `:EasyAlign` command
+
+If you prefer command-line or do not want to start interactive mode, you can use
+`:EasyAlign` command instead.
+
+| Mode                                       | Command                                          |
+| ------------------------------------------ | ------------------------------------------------ |
+| Interactive mode                           | `:EasyAlign[!] [OPTIONS]`                        |
+| Live interactive mode                      | `:LiveEasyAlign[!] [...]`                        |
+| Non-interactive mode (predefined rules)    | `:EasyAlign[!] [N-th] DELIMITER_KEY [OPTIONS]`   |
+| Non-interactive mode (regular expressions) | `:EasyAlign[!] [N-th] /REGEXP/ [OPTIONS]`        |
 
 ### Interactive mode
 
-The command will go into the interactive mode when no argument is given.
-For convenience, it is advised that you define a mapping for triggering it in
-your `.vimrc`.
+The following sections will assume that you have `<Plug>(EasyAlign)` mappings in
+your .vimrc as below:
 
 ```vim
-vnoremap <silent> <Enter> :EasyAlign<cr>
+" Start interactive EasyAlign in visual mode (e.g. vip<Enter>)
+vmap <Enter> <Plug>(EasyAlign)
+
+" Start interactive EasyAlign for a motion/text object (e.g. <Leader>aip)
+nmap <Leader>a <Plug>(EasyAlign)
 ```

+
+#### Using regular expressions
+
+Instead of finishing the command with a predefined delimiter key, you can type
+in a regular expression after `<CTRL-/>` or `<CTRL-X>` key.
+For example, if you want to align text around all occurrences of numbers:
+
+- `<Enter>`
+- `*`
+- `<CTRL-X>`
+  - `[0-9]\+`
+
+#### Alignment options in interactive mode
+
+While in interactive mode, you can set alignment options using special shortcut
+keys listed below. The meaning of each option will be described in
+[the following sections](https://github.com/junegunn/vim-easy-align#alignment-options).
+
+| Key       | Option             | Values                                             |
+| --------- | ------------------ | -------------------------------------------------- |
+| `CTRL-F`  | `filter`           | Input string (`[gv]/.*/?`)                         |
+| `CTRL-I`  | `indentation`      | shallow, deep, none, keep                          |
+| `CTRL-L`  | `left_margin`      | Input number or string                             |
+| `CTRL-R`  | `right_margin`     | Input number or string                             |
+| `CTRL-D`  | `delimiter_align`  | left, center, right                                |
+| `CTRL-U`  | `ignore_unmatched` | 0, 1                                               |
+| `CTRL-G`  | `ignore_groups`    | [], ['String'], ['Comment'], ['String', 'Comment'] |
+| `CTRL-O`  | `mode_sequence`    | Input string (`/[lrc]+\*{0,2}/`)                   |
+| `<Left>`  | `stick_to_left`    | `{ 'stick_to_left': 1, 'left_margin': 0 }`         |
+| `<Right>` | `stick_to_left`    | `{ 'stick_to_left': 0, 'left_margin': 1 }`         |
+| `<Down>`  | `*_margin`         | `{ 'left_margin': 0, 'right_margin': 0 }`          |
+
+### Live interactive mode
+
+If you're performing a complex alignment where multiple options should be
+carefully adjusted, try "live interactive mode" where you can preview the result
+of the alignment on-the-fly as you type in.
+
+Live interactive mode can be started with either `<Plug>(LiveEasyAlign)` or
+`:LiveEasyAlign` command.
+
+In live interactive mode, you have to type in the same delimiter (or `CTRL-X` on
+regular expression) again to finalize the alignment. This allows you to preview
+the result of the alignment and freely change the delimiter using backspace key
+without leaving the interactive mode.
 
 ### Non-interactive mode
 
-Instead of going into the interactive mode, you can type in arguments to
-`:EasyAlign` command. In non-interactive mode, you can even use arbitrary
-regular expressions.
+Instead of starting interactive mode, you can use declarative, non-interactive
+`:EasyAlign` command.
 
 ```vim
 " Using predefined alignment rules
-:EasyAlign[!] [FIELD#] DELIMITER_KEY [OPTIONS]
+"   :EasyAlign[!] [N-th] DELIMITER_KEY [OPTIONS]
+:EasyAlign :
+:EasyAlign =
+:EasyAlign *=
+:EasyAlign 3\
 
 " Using arbitrary regular expressions

+:EasyAlign /[:;]\+/
+:EasyAlign 2/[:;]\+/
+:EasyAlign */[:;]\+/
+:EasyAlign **/[:;]\+/
 ```
 
-For example, when aligning the following lines around colons and semi-colons,
+A command can end with alignment options, [each of which will be discussed in

+### Filtering lines
+
+With `filter` option, you can align lines that only match or do not match a
+given pattern. There are several ways to set the pattern.
+
+1. Press `CTRL-F` in interactive mode and type in `g/pat/` or `v/pat/`
+2. In command-line, it can be written in dictionary format: `{'filter': 'g/pat/'}`
+3. Or in shorthand notation: `g/pat/` or `v/pat/`
+
+(You don't need to escape '/'s in the regular expression)
+
+#### Examples
+
+```vim
+" Start interactive mode with filter option set to g/hello/
+EasyAlign g/hello/
+
+" Start live interactive mode with filter option set to v/goodbye/
+LiveEasyAlign v/goodbye/
+
+" Align the lines with 'hi' around the first colons

+```
+
+In interactive mode, you can change the option value with `CTRL-I` key.
+
+### Alignments over multiple occurrences of delimiters
+
+As stated above, "N-th" parameter is used to target specific occurrences of
+the delimiter when it appears multiple times in each line.
+
+To recap:
+
+```vim
+" Left-alignment around the FIRST occurrences of delimiters
+:EasyAlign =
+
+" Left-alignment around the SECOND occurrences of delimiters
+:EasyAlign 2=
+
+" Left-alignment around the LAST occurrences of delimiters
+:EasyAlign -=
+
+" Left-alignment around ALL occurrences of delimiters
+:EasyAlign *=
+
+" Left-right ALTERNATING alignment around all occurrences of delimiters
+:EasyAlign **=
+
+" Right-left ALTERNATING alignment around all occurrences of delimiters
+:EasyAlign! **=
+```
+
+In addition to these, you can fine-tune alignments over multiple occurrences of
+the delimiters with 'mode_sequence' option. (The option can also be set
+in interactive mode with the special key `CTRL-O`)
+
+```vim
+" Left alignment over the first two occurrences of delimiters
+:EasyAlign = { 'mode_sequence': 'll' }
+
+" Right, left, center alignment over the 1st to 3rd occurrences of delimiters
+:EasyAlign = { 'm': 'rlc' }
+
+" Using shorthand notation
+:EasyAlign = mrlc
+
+" Right, left, center alignment over the 2nd to 4th occurrences of delimiters
+:EasyAlign 2=mrlc
+
+" (*) Repeating alignments (default: l, r, or c)
+"   Right, left, center, center, center, center, ...
+:EasyAlign *=mrlc
+
+" (**) Alternating alignments (default: lr or rl)
+"   Right, left, center, right, left, center, ...
+:EasyAlign **=mrlc
+
+" Right, left, center, center, center, ... repeating alignment
+" over the 3rd to the last occurrences of delimiters
+:EasyAlign 3=mrlc*
+
+" Right, left, center, right, left, center, ... alternating alignment
+" over the 3rd to the last occurrences of delimiters
+:EasyAlign 3=mrlc**
+```
+
 ### Extending alignment rules
 
 Although the default rules should cover the most of the use cases,
 you can extend the rules by setting a dictionary named `g:easy_align_delimiters`.
 
-#### Example
+You may refer to the definitions of the default alignment rules
+[here](https://github.com/junegunn/vim-easy-align/blob/2.9.0/autoload/easy_align.vim#L29).
+
+#### Examples

+Other options
+-------------
+
+### Disabling &foldmethod during alignment
+
+[It is reported](https://github.com/junegunn/vim-easy-align/issues/14) that
+`&foldmethod` value of `expr` or `syntax` can significantly slow down the
+alignment when editing a large, complex file with many folds. To alleviate this
+issue, EasyAlign provides an option to temporarily set `&foldmethod` to `manual`
+during the alignment task. In order to enable this feature, set
+`g:easy_align_bypass_fold` switch to 1.
+
+```vim
+let g:easy_align_bypass_fold = 1
+```
+
+### Left/right/center mode switch in interactive mode
+
+In interactive mode, you can choose the alignment mode you want by pressing
+enter keys. The non-bang command, `:EasyAlign` starts in left-alignment mode
+and changes to right and center mode as you press enter keys, while the bang
+version first starts in right-alignment mode.
+
+- `:EasyAlign`
+  - Left, Right, Center
+- `:EasyAlign!`
+  - Right, Left, Center
+
+If you do not prefer this default mode transition, you can define your own
+settings as follows.
+
+```vim
+let g:easy_align_interactive_modes = ['l', 'r']
+let g:easy_align_bang_interactive_modes = ['c', 'r']
+```
+
 Advanced examples and use cases
 -------------------------------
 
 See [EXAMPLES.md](https://github.com/junegunn/vim-easy-align/blob/master/EXAMPLES.md)
 for more examples.
 
+
+Related work
+------------
+
+There are two well-known plugins with the same goal as that of easy-align.
+
+- [DrChip's Alignment Tool for Vim](http://www.drchip.org/astronaut/vim/align.html) (herein will be referred to as "Align")
+- [Tabular](https://github.com/godlygeek/tabular)
+
+Both are great plugins with very large user bases. I actually had been a Tabular
+user for a couple of years before I finally made up my mind to roll out my own.
+
+So why would someone choose easy-align over those two?
+
+Feature-by-feature comparison I believe is not quite useful, since a typical
+user will end up using only a small subset of the features.
+So I will mention just a few core benefits of easy-align.
+
+### Ease of use
+
+As the name implies, easy-align is *easier* to use. Its interactive mode
+allows you to achieve what you want with just a few keystrokes.
+The key sequence is mnemonic, so it's easy to remember and execute.
+It even feels like a native Vim command!
+
+- *Right-align*: `<Enter><Enter>`
+- around the *second* occurrences: `2`
+- of *whitespaces*: `<Space>`
+
+For the simplest cases, Tabular and Align are also easy to use. But sooner or
+later, you will find yourself scratching your head, trying to come up with some
+complex regular expressions.
+
+_"How am I going to align the third to the last word in each line to the right
+without affecting the ones before it?"_
+
+### Clean
+
+easy-align doesn't clutter your workspace with mappings and global
+variables. All you would need is a single mapping to the interactive EasyAlign
+command, and even that is totally up to you.
+
+### Optimized for code editing
+
+easy-align by default performs syntax-aware alignment, which is invaluable
+when editing codes.
+
+Try to come up with a regular expression to correctly format the following code
+snippet. With easy-align under default configuration and a mapping, it can
+be done with just two keystrokes: `<Enter>:`
+
+```javascript
+var jdbc = {
+  // JDBC driver for MySQL database:
+  driver: "com.mysql.jdbc.Driver",
+  /* JDBC URL for the connection (jdbc:mysql://HOSTNAME/DATABASE) */
+  url: 'jdbc:mysql://localhost/test',
+  database: "test",
+  "user:pass":"r00t:pa55"
+};
+```
+
+(To be fair, Align also can be configured to consider syntax highlighting with
+`g:AlignSkip` function reference which should point to a custom function that
+looks up the syntax group of a character on a certain position)
+
+### Thoroughly tested
+
+Virtually every aspect of easy-align is being tested with a comprehensive
+set of test cases using [Vader.vim](https://github.com/junegunn/vader.vim).
+
+### "Okay. So should I switch?"
+
+Maybe, but I can't really say. I have no ambition to make easy-align
+an absolute superior to the others. For some cases, easy-align works better
+than the others, but for some other cases, Tabular or Align.vim might be a
+better choice.
+
+So try it yourself and see if it works for you!
