 Have fun, and work on whatever floats your boat. Take It Easy :tm:.
 
+Don't forget to **write documentation** for whatever it is you are doing.
+See the ["Writing Documentation"](#writing-documentation) section.
+
+Remember to write Vader tests for most of the code you write. You can look at
+existing Vader tests in the `test` directory for examples.
+
+When writing code, follow the [Google Vimscript Style
+Guide](https://google.github.io/styleguide/vimscriptguide.xml), and run `vint
+-s` on your files to check for most of what the guide mentions and more. If you
+install this plugin (ALE) and install [Vint](https://github.com/Kuniwak/vint), it

+issue has already been reported, but you have some new insight, please add
+a comment to the existing issue.
+
+Please read the FAQ in the README before creating any issues. A feature
+you desire may already exist and be documented, or the FAQ might explain
+how to solve a problem you have already.
+
+Please try and describe any issues reported with as much detail as you can
+provide about your Vim version, the linter you were trying to run, your
+operating system, or any other information you think might be helpful.
+
+Please describe your issue in clear, grammatically correct, and easy to
+understand English. You are more likely to see an issue resolved if others

-# 2.1. Adding a New Linter
+<a name="adding-a-new-linter"></a>
 
-If you add a new linter, look for existing handlers first in the [handlers.vim](plugin/ale/handlers.vim) file. One of the handlers
-there may already be able to handle your lines of output. If you find that your new linter replicates an existing error handler,
-consider pulling it up into the [handlers.vim](plugin/ale/handlers.vim) file, and use the generic handler in both places.
+### 3.i. Adding a New Linter
 
-When you add a linter, make sure the language for the linter and the linter itself are present in the table in the
-[README.md](README.md) file and in the Vim [help file](doc/ale.txt). The programs and linters are sorted alphabetically in the
-table and list.
+If you add a new linter, look for existing handlers first in the

+[handlers](autoload/ale/handlers) directory, and use the generic handler in

-# 2.2. Adding New Options
+When you add a linter, make sure the language for the linter and the linter
+itself are present in the table in the [README.md](README.md) file and in the
+Vim [help file](doc/ale.txt). The programs and linters should be sorted
+alphabetically in the table and list.
 
-If you add new options to the plugin, make sure to document those new options in the [README.md](README.md) file, and also
-in the [help file](doc/ale.txt). Follow the format of other options in each. Global options should appear in the README
-file, and in the relevant section in the help file, and options specific to a particular linter should go in the section
-for that linter.
+<a name="adding-new-options"></a>
 
-<a name="compiling"></a>
+### 3.ii. Adding New Options
 
-# 3. Compiling the Windows stdin wrapper
+If you add new options to the plugin, make sure to document those new options
+in the [README.md](README.md) file, and also in the [help file](doc/ale.txt).
+Follow the format of other options in each. Global options should appear in the
+README file, and in the relevant section in the help file. Options specific
+to a particular linter should appear in the section for that linter.
 
-To compile the stdin wrapper program for Windows, when updating the D program, you will need to compile the program with
-[LDC](https://github.com/ldc-developers/ldc) in release mode. Download and install the Community edition of Visual Studio
-from [the Visual Studio website](https://www.visualstudio.com/downloads/) first before installing LDC. LDC typically comes in
-a ZIP you can just extract somewhere.
+Linter options for customizing general argument lists should be named
+`g:ale_<filetype>_<linter>_options`, so that all linters can have similar
+global variable names.
 
-Make sure to compile with the 32-bit architecture flag, otherwise the EXE will not run on 32-bit machines.
+Any options for linters should be set to some default value so it is always
+easy to see what the default is with `:echo g:ale...`.

+<a name="writing-documentation"></a>
+
+## 4. Writing Documentation
+
+If you are adding new linters, changing the API, adding new options, etc., you
+_must_ write some documentation describing it in the `doc/ale.txt` file.  New
+linters _must_ be added to the `README.md` file too, so other users can get a
+quick overview of the supported tools.
+
+<a name="documenting-new-linters"></a>
+
+### 4.i Documenting New Linters
+
+If you add a new linter to the project, edit the table in the `README.md` file,
+and edit the list of linters at the top of the `doc/ale.txt` file. The linters
+should be sorted vertically in lexicographic (alphabetical) order by the
+programming language name or filetype, and the tools for each language should
+be sorted in lexicographic order horizontally. Sorting in this manner is a fair
+manner of presenting all of the information in an easy to scan way, without
+giving some unfair preference to any particular tool or language.
+
+<a name="editing-online-documentation"></a>
+
+### 4.ii Editing the Online Documentation
+
+The "online documentation" file used for this project lives in `doc/ale.txt`.
+This is the file used for generating `:help` text inside Vim itself. There are
+some guidelines to follow for this file.
+
+1. Keep all text within a column size of 79 characters, inclusive.
+2. Open a section with 79 `=` or `-` characters, for headings and subheadings.
+3. Sections should have a _single_ blank line before or after.
+4. Between descriptions of variables/functions/commands, use _two_ blank lines.
+5. Up-indent the description of a variable/function/command by two spaces.
+6. Place tags at the ends of lines, with the final characters on column 79.
+   All of the tags should line up perfectly on the same column as you scan
+   down through the document.
+7. Keep the table of contents balanced so the longest tag link ends on column
+   79, and so all links line up perfectly on their first character, on the
+   left.
+
+<a name="documenting-linter-options"></a>
+
+### 4.iii Documenting Linter Options
+
+For documenting new linter options, please add a new sub-section under the
+"Linter Specific Options" section describing all of the global options added
+for each linter, and what the default values of the options are. All global
+options for linters should be set to some default value. This will allow users
+to look up the default value easily by typing `:echo g:ale_...`.
+
+<a name="in-case-of-busses"></a>
+
+## 5. In Case of Busses
+
+Should the principal author of the ALE project and all collaborators with the
+required access needed to properly administrate the project on GitHub or any
+other website either perish or disappear, whether by tragic traffic accident
+or government abduction, etc., action should be taken to ensure that the
+project continues. If no one is left to administer the project where it is
+hosted, please fork the project and nominate someone capable to administer it.
+Preferably, in such an event, a single fork of the project will replace the
+original, and life will go on, except the life of whoever vanished, because
+then they will probably be dead.
+
+Should w0rp suddenly disappear, then he was probably killed in a traffic
+accident, or the government finally decided to kill him and make it look like
+suicide. In the latter event, please subvert said government and restore
+order to the universe, and ensure peace for mankind.

+READ THIS: Before creating a pull request, please consider the following first.
+
+* The most important thing you can do is write tests. Code without tests
+  probably doesn't work, and will almost certainly stop working later on. Pull
+  requests without tests probably won't be accepted, although there are some
+  exceptions.
+* Read the Contributing guide linked above first.
+* If you are adding a new linter, remember to update the README.md file and
+  doc/ale.txt first.
+* If you add or modify a function for converting error lines into loclist items
+  that ALE can work with, please add Vader tests for them. Look at existing
+  tests in the test/handler directory, etc.
+* If you add or modify a function for computing a command line string for
+  running a command, please add Vader tests for that.
+* Generally try and cover anything with Vader tests, although some things just
+  can't be tested with Vader, or at least they can be hard to test. Consider

+  a discussion about it.
+* Have fun!

 linters will be re-run in the background to check your syntax when you open
 new buffers or as you make edits to your files.
 
-### Options
+The behaviour of linting can be configured with a variety of options,
+documented in [the Vim help file](doc/ale.txt). For more information on the
+options ALE offers, consult `:help ale-options` for global options and `:help
+ale-linter-options` for options specified to particular linters.
 
-A full list of options supported for configuring this plugin in your

-| Option | Description | Default |
-| ------ | ----------- | ------- |
-| `g:ale_echo_cursor` | echo errors when the cursor is over them | `1` |

+### 2.ii Fixing
 
-### Selecting Particular Linters
+ALE can fix files with the `ALEFix` command. Functions need to be configured
+for different filetypes with the `g:ale_fixers` variable. For example, the
+following code can be used to fix JavaScript code with ESLint:
+
+```vim
+" Put this in vimrc or a plugin file of your own.
+" After this is configured, :ALEFix will try and fix your JS code with ESLint.
+let g:ale_fixers = {
+\   'javascript': ['eslint'],
+\}
+
+" Set this setting in vimrc if you want to fix files automatically on save.
+" This is off by default.
+let g:ale_fix_on_save = 1
+```
+
+The `:ALEFixSuggest` command will suggest some supported tools for fixing code,
+but fixers can be also implemented with functions, including lambda functions
+too. See `:help ale-fix` for detailed information.

+### 2.iii Completion
+
+ALE offers some support for completion via hijacking of omnicompletion while you
+type. All of ALE's completion information must come from Language Server
+Protocol linters, or similar protocols. At the moment, completion is only
+supported for TypeScript code with `tsserver`, when `tsserver` is enabled. You
+can enable completion like so:
+
+```vim
+" Enable completion where available.

+## 3. Installation
+
+To install this plugin, you should use one of the following methods.
+For Windows users, replace usage of the Unix `~/.vim` directory with
+`%USERPROFILE%\vimfiles`, or another directory if you have configured
+Vim differently. On Windows, your `~/.vimrc` file will be similarly
+stored in `%USERPROFILE%\_vimrc`.
+
+<a name="standard-installation"></a>
+
+### 3.i. Installation with Vim package management
+
+In Vim 8 and NeoVim, you can install plugins easily without needing to use
+any other tools. Simply clone the plugin into your `pack` directory.
+
+#### Vim 8 on Unix
+
+```bash
+mkdir -p ~/.vim/pack/git-plugins/start
+git clone https://github.com/w0rp/ale.git ~/.vim/pack/git-plugins/start/ale
+```
+
+#### NeoVim on Unix
+
+```bash
+mkdir -p ~/.local/share/nvim/site/pack/git-plugins/start
+git clone https://github.com/w0rp/ale.git ~/.local/share/nvim/site/pack/git-plugins/start/ale
+```
+
+#### Vim 8 on Windows
+
+```bash
+# Run these commands in the "Git for Windows" Bash terminal
+mkdir -p ~/vimfiles/pack/git-plugins/start
+git clone https://github.com/w0rp/ale.git ~/vimfiles/pack/git-plugins/start/ale
+```
+
+#### Generating Vim help files
+
+You can add the following line to your vimrc files to generate documentation
+tags automatically, if you don't have something similar already, so you can use
+the `:help` command to consult ALE's online documentation:
+
+```vim
+" Put these lines at the very end of your vimrc file.
+
+" Load all plugins now.
+" Plugins need to be added to runtimepath before helptags can be generated.
+packloadall
+" Load all of the helptags now, after plugins have been loaded.
+" All messages and errors will be ignored.
+silent! helptags ALL

-### Statusline
-
-You can use `ALEGetStatusLine()` to integrate ALE into vim statusline.
-To enable it, you should have in your `statusline` settings
+ALE sets some background colors automatically for warnings and errors
+in the sign gutter, with the names `ALEErrorSign` and `ALEWarningSign`.
+These colors can be customised, or even removed completely:
 
 ```vim
-%{ALEGetStatusLine()}
+highlight clear ALEErrorSign
+highlight clear ALEWarningSign
 ```
 
-When errors are detected a string showing the number of errors will be shown.
-You can customize the output format using the global list `g:ale_statusline_format` where:
+<a name="faq-statusline"></a>
 
-- The 1st element is for errors
-- The 2nd element is for warnings
-- The 3rd element is for when no errors are detected
+### 5.iv. How can I show errors or warnings in my statusline?
 
-e.g
+[vim-airline](https://github.com/vim-airline/vim-airline) integrates with ALE
+for displaying error information in the status bar. If you want to see the
+status for ALE in a nice format, it is recommended to use vim-airline with ALE.
+The airline extension can be enabled by adding the following to your vimrc:
 
 ```vim
-let g:ale_statusline_format = ['⨉ %d', '⚠ %d', '⬥ ok']
+" Set this. Airline will handle the rest.
+let g:airline#extensions#ale#enabled = 1
 ```
 
-![Statusline with issues](img/issues.png)
-![Statusline with no issues](img/no_issues.png)
+If you don't want to use vim-airline, you can implement your own statusline
+function without adding any other plugins. ALE provides a function for counting
+the number of problems for this purpose, named `ale#statusline#Count`.
 
+Say you want to display all errors as one figure, and all non-errors as another
+figure. You can do the following:
 
-### Customize echoed message
+```vim
+function! LinterStatus() abort
+    let l:counts = ale#statusline#Count(bufnr(''))
+
+    let l:all_errors = l:counts.error + l:counts.style_error
+    let l:all_non_errors = l:counts.total - l:all_errors
+
+    return l:counts.total == 0 ? 'OK' : printf(
+    \   '%dW %dE',
+    \   all_non_errors,
+    \   all_errors

+### 5.vii. How can I execute some code when ALE stops linting?
 
-### Installation with Pathogen
-
-To install this module with [Pathogen](https://github.com/tpope/vim-pathogen),
-you should clone this repository to your bundle directory, and ensure
-you have the line `execute pathogen#infect()` in your `~/.vimrc` file.
-You can run the following commands in your terminal to do so:
-
-```bash
-cd ~/.vim/bundle
-git clone https://github.com/w0rp/ale.git

-
-### Installation with Vundle
-
-You can install this plugin using [Vundle](https://github.com/VundleVim/Vundle.vim)
-by using the path on GitHub for this repository.
+ALE runs its own [autocmd](http://vimdoc.sourceforge.net/htmldoc/autocmd.html)
+event whenever has a linter has been successfully executed and processed. This
+autocmd event can be used to call arbitrary functions after ALE stops linting.
 
 ```vim

+    autocmd!
+    autocmd User ALELint call YourFunction()
+augroup END
 ```
 
-See the Vundle documentation for more information.
+<a name="faq-navigation"></a>
 
-### Manual Installation
+### 5.viii. How can I navigate between errors quickly?
 
-For installation without a package manager, you can clone this git repository
-into a bundle directory as with pathogen, and add the repository to your
-runtime path yourself. First clone the repository.
-
-```bash
-cd ~/.vim/bundle
-git clone https://github.com/w0rp/ale.git
-```
-
-Then, modify your `~/.vimrc` file to add this plugin to your runtime path.
+ALE offers some commands with `<Plug>` keybinds for moving between warnings and
+errors quickly. You can map the keys Ctrl+j and Ctrl+k to moving between errors
+for example:
 
 ```vim
-set nocompatible
-filetype off
-
-let &runtimepath.=',~/.vim/bundle/ale'
-
-filetype plugin on
+nmap <silent> <C-k> <Plug>(ale_previous_wrap)
+nmap <silent> <C-j> <Plug>(ale_next_wrap)
 ```
 
-Because the author of this plugin is a weird nerd, this is his preferred
-installation method.

+`:help ale-navigation-commands`.

+### 5.ix. How can I run linters only when I save files?
+
+ALE offers an option `g:ale_lint_on_save` for enabling running the linters
+when files are saved. This option is enabled by default. If you only
+wish to run linters when files are saved, you can turn the other
+options off.

+" Write this in your vimrc file
+let g:ale_lint_on_text_changed = 'never'
+" You can disable this option too
+" if you don't want linters to run on opening a file
+let g:ale_lint_on_enter = 0
+```
+

+files, you can set `g:ale_lint_on_save` to `0`.

+
+### 5.x. How can I use the quickfix list instead of the loclist?
+
+The quickfix list can be enabled by turning the `g:ale_set_quickfix`
+option on. If you wish to also disable the loclist, you can disable
+the `g:ale_set_loclist` option.
+
+```vim
+" Write this in your vimrc file
+let g:ale_set_loclist = 0
+let g:ale_set_quickfix = 1
+```
+
+If you wish to show Vim windows for the loclist or quickfix items
+when a file contains warnings or errors, `g:ale_open_list` can be
+set to `1`. `g:ale_keep_list_window_open` can be set to `1`
+if you wish to keep the window open even after errors disappear.
+
+```vim
+let g:ale_open_list = 1
+" Set this if you want to.
+" This can be useful if you are combining ALE with
+" some other plugin which sets quickfix errors, etc.
+let g:ale_keep_list_window_open = 1
+```
+
+<a name="faq-jsx-stylelint-eslint"></a>
+
+### 5.xi. How can I check JSX files with both stylelint and eslint?
+
+If you configure ALE options correctly in your vimrc file, and install
+the right tools, you can check JSX files with stylelint and eslint.
+
+First, install eslint and install stylelint with
+[stylelint-processor-styled-components](https://github.com/styled-components/stylelint-processor-styled-components).
+
+Supposing you have installed both tools correctly, configure your .jsx files so
+`jsx` is included in the filetype. You can use an `autocmd` for this.
+
+```vim
+augroup FiletypeGroup
+    autocmd!
+    au BufNewFile,BufRead *.jsx set filetype=javascript.jsx
+augroup END
+```
+
+Supposing the filetype has been set correctly, you can set the following
+options in your vimrc file:
+
+```vim
+let g:ale_linters = {'jsx': ['stylelint', 'eslint']}
+let g:ale_linter_aliases = {'jsx': 'css'}
+```
+
+ALE will alias the `jsx` filetype so it uses the `css` filetype linters, and
+use the original Array of selected linters for `jsx` from the `g:ale_linters`
+object. All available linters will be used for the filetype `javascript`, and
+no linter will be run twice for the same file.
+
+<a name="faq-my-battery-is-sad"></a>
+
+### 5.xii. Will this plugin eat all of my laptop battery power?
+
+ALE takes advantage of the power of various tools to check your code. This of
+course means that CPU time will be used to continuously check your code. If you
+are concerned about the CPU time ALE will spend, which will of course imply
+some cost to battery life, you can adjust your settings to make your CPU do
+less work.
+
+First, consider increasing the delay before which ALE will run any linters
+while you type. ALE uses a timeout which is cancelled and reset every time you
+type, and this delay can be increased so linters are run less often. See
+`:help g:ale_lint_delay` for more information.
+
+If you don't wish to run linters while you type, you can disable that
+behaviour. Set `g:ale_lint_on_text_changed` to `never` or `normal`. You won't
+get as frequent error checking, but ALE shouldn't block your ability to edit a
+document after you save a file, so the asynchronous nature of the plugin will
+still be an advantage.
+
+If you are still concerned, you can turn the automatic linting off altogether,
+including the option `g:ale_lint_on_enter`, and you can run ALE manually with
+`:ALELint`.
