-### 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 guidlines 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 adduction, 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

+ALE acts as a "language client" to support a variety of Language Server Protocol

+* Go To Definition (`:ALEGoToDefinition`)
+* Completion (`let g:ale_completion_enabled = 1`)
+* Finding references (`:ALEFindReferences`)
+* Hover information (`:ALEHover`)
+
+If you don't care about Language Server Protocol, ALE won't load any of the code

+<a name="faq-c-configuration"></a>
+
+### 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`, `clangtidy` and `cquery` 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.
+
+<a name="faq-list-window-height"></a>
+
+### 5.xvi. How can I configure the height of the list in which ALE displays errors?
+
+To set a default height for the error list, use the `g:ale_list_window_size` variable.
+
+```vim
+" Show 5 lines of errors (default: 10)
+let g:ale_list_window_size = 5
