+### 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
+color scheme which produces ugly highlights. For example:

+highlight ALEWarning ctermbg=DarkMagenta

+
+<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` 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.
