+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

+* 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
+  breaking up your code so that some parts can be tested, and generally open up
+  a discussion about it.
+* Have fun!

+<a name="usage-fixing"></a>
+
+### 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:
+
+```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.
+let g:ale_completion_enabled = 1
+```
+
+See `:help ale-completion` for more information.

+### 2.iv Go To Definition
+
+ALE supports jumping to the definition of words under your cursor with the
+`:ALEGoToDefinition` command using any enabled LSP linters and `tsserver`.
+

 ## 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%\_vim`, or another directory if you have configured
+`%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.

+" Load all of the helptags now, after plugins have been loaded.
+" All messages and errors will be ignored.

+### 5.iv. How can I change or disable the highlights ALE uses?
+
+ALE's highlights problems with highlight groups which link to `SpellBad`,
+`SpellCap`, `error`, and `todo` groups by default. The characters that are
+highlighted depend on the linters being used, and the information provided to
+ALE.
+
+Highlighting can be disabled completely by setting `g:ale_set_highlights` to
+`0`.
+
+```vim
+" Set this in your vimrc file to disabling highlighting
+let g:ale_set_highlights = 0
+```
+
+You can control all of the highlights ALE uses, say if you are using a different

+[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

+The airline extension can be enabled by adding the following to your vimrc:
 
 ```vim
-%{ALEGetStatusLine()}
+" Set this. Airline will handle the rest.
+let g:airline#extensions#ale#enabled = 1
 ```
 
-When errors are detected a string showing the number of errors will be shown.

+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`.
 
-- The 1st element is for errors
-- The 2nd element is for warnings
-- The 3rd element is for when no errors are detected

 ```vim

+
+### 5.xiv. How can I configure my C or C++ project?
+
+The structure of C and C++ projects varies wildly from project to project, with
+many different build tools being used for building them, and many different
+formats for project configuration files. ALE can run compilers easily, but
+ALE cannot easily detect which compiler flags to use.
+
+Some tools and build configurations can generate
+[compile_commands.json](https://clang.llvm.org/docs/JSONCompilationDatabase.html)
+files. The `cppcheck`, `clangcheck` and `clangtidy` linters can read these
+files for automatically determining the appropriate compiler flags to use.
+
+For linting with compilers like `gcc` and `clang`, and with other tools, you
+will need to tell ALE which compiler flags to use yourself. You can use
+different options for different projects with the `g:ale_pattern_options`
+setting.  Consult the documentation for that setting for more information.
+`b:ale_linters` can be used to select which tools you want to run, say if you
+want to use only `gcc` for one project, and only `clang` for another.
+
+You may also configure buffer-local settings for linters with project-specific
+vimrc files. [local_vimrc](https://github.com/LucHermitte/local_vimrc) can be
+used for executing local vimrc files which can be shared in your project.
+
+<a name="faq-buffer-configuration"></a>
+
+### 5.xv. How can I configure ALE differently for different buffers?
+
+ALE offers various ways to configure which linters or fixers are run, and
+other settings. For the majority of ALE's settings, they can either be
+configured globally with a `g:` variable prefix, or for a specific buffer
+with a `b:` variable prefix. For example, you can configure a Python ftplugin
+file like so.
+
+```vim
+" In ~/.vim/ftplugin/python.vim
+
+" Check Python files with flake8 and pylint.
+let b:ale_linters = ['flake8', 'pylint']
+" Fix Python files with autopep8 and yapf.
+let b:ale_fixers = ['autopep8', 'yapf']
+" Disable warnings about trailing whitespace for Python files.
+let b:ale_warn_about_trailing_whitespace = 0
+```
+
+For configuring files based on regular expression patterns matched against the
+absolute path to a file, you can use `g:ale_pattern_options`.
+
+```vim
+" Do not lint or fix minified files.
+let g:ale_pattern_options = {
+\ '\.min\.js$': {'ale_linters': [], 'ale_fixers': []},
+\ '\.min\.css$': {'ale_linters': [], 'ale_fixers': []},
+\}
+" If you configure g:ale_pattern_options outside of vimrc, you need this.
+let g:ale_pattern_options_enabled = 1
+```
+
+Buffer-local variables for settings always override the global settings.
