+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

-
-## 1. Guidelines
-
-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
-will check your code while you type.
-
-<a name="issues"></a>
-
-## 2. Creating Issues
-
-Before creating any issues, please look through the current list of issues and
-pull requests, and ensure that the issue hasn't already been reported. If an
-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
-can understand you.
-
-<a name="pull-requests"></a>
-
-## 3. Creating Pull Requests
-
-For code you write, make sure to credit yourself at the top of files you add,
-and probably those you modify. You can write some comments at the top of your
-VIM files.
-
-```vim
-" Author: John Smith <john.smith@gmail.com>
-" Description: This file adds support for awesomelinter for the best language ever.
-```
-
-If you want to credit multiple authors, you can comma separate them.
-
-```vim
-" Author: John Smith <john.smith@gmail.com>, Jane Doe <https://jane-doe.info>
-```
-
-<a name="adding-a-new-linter"></a>
-
-### 3.i. Adding a New Linter
-
-If you add a new linter, look for existing handlers first in the
-[handlers](autoload/ale/handlers) directory. 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](autoload/ale/handlers) directory, and use the generic handler in
-both places.
-
-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.
-
-<a name="adding-new-options"></a>
-
-### 3.ii. Adding New Options
-
-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.
-
-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.
-
-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.

+ALE offers support for fixing code with command line tools in a non-blocking
+manner with the `:ALEFix` feature, supporting tools in many languages, like
+`prettier`, `eslint`, `autopep8`, and more.
+
+ALE acts as a "language client" to support a variety of Language Server Protocol
+features, including:
+
+* Diagnostics (via Language Server Protocol linters)
+* Go To Definition (`:ALEGoToDefinition`)
+* Completion (`let g:ale_completion_enabled = 1` before ALE is loaded)
+* Finding references (`:ALEFindReferences`)
+* Hover information (`:ALEHover`)
+* Symbol search (`:ALESymbolSearch`)
+
+If you don't care about Language Server Protocol, ALE won't load any of the code
+for working with it unless needed. One of ALE's general missions is that you
+won't pay for the features that you don't use.

 ### 2.ii Fixing
 
 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:
+either in each buffer with a `b:ale_fixers`, or globally with `g:ale_fixers`.
+
+The recommended way to configure fixers is to define a List in an ftplugin file.
 
 ```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.
+" In ~/.vim/ftplugin/javascript.vim, or somewhere similar.
+
+" Fix files with prettier, and then ESLint.
+let b:ale_fixers = ['prettier', 'eslint']
+" Equivalent to the above.
+let b:ale_fixers = {'javascript': ['prettier', 'eslint']}
+```
+
+You can also configure your fixers from vimrc using `g:ale_fixers`, before or
+after ALE has been loaded.
+
+A `*` in place of the filetype will apply a List of fixers to all files which
+do not match some filetype in the Dictionary.
+
+Note that using a plain List for `g:ale_fixers` is not supported.
+
+```vim
+" In ~/.vim/vimrc, or somewhere similar.
 let g:ale_fixers = {
+\   '*': ['remove_trailing_lines', 'trim_whitespace'],
 \   'javascript': ['eslint'],
 \}
+```
 
-" Set this setting in vimrc if you want to fix files automatically on save.
-" This is off by default.
+If you want to automatically fix files when you save them, you need to turn
+a setting on in vimrc.
+
+```vim
+" Set this variable to 1 to fix files when you save them.
 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.

+
+To check Vue files with ESLint, your ESLint project configuration file must be
+configured to use the [Vue plugin](https://github.com/vuejs/eslint-plugin-vue).
+After that, you need to configure ALE so it will run the JavaScript ESLint
+linter on your files. The settings you need are similar to the settings needed
+for checking JSX code with both stylelint and ESLint, in the previous section.
+
+```vim
+" In ~/.vim/ftplugin/vue.vim, or somewhere similar.

+let b:ale_linters = ['eslint', 'vls']
+```
+
+Run `:ALEInfo` to see which linters are available after telling ALE to run
+JavaScript linters on Vue files. Not all linters support checking Vue files.
+
+If you don't want to configure your linters in ftplugin files for some reason,
