 ## 1. Supported Languages and Tools

-ALE supports a wide variety of languages and tools. See the
-[full list](supported-tools.md) in the
-[Supported Languages and Tools](supported-tools.md) page.
+This plugin supports the following languages and tools. All available
+tools will be run in combination, so they can be complementary.
+
+<!--
+Keep the table rows sorted alphabetically by the language name,
+and the tools in the tools column sorted alphabetically by the tool
+name. That seems to be the fairest way to arrange this table.
+
+Remember to also update doc/ale.txt, which has a similar list with different
+formatting.
+-->
+
+**Notes:**
+
+* *^ No linters for text or Vim help filetypes are enabled by default.*
+* *!! These linters check only files on disk. See `:help ale-lint-file-linters`*

-### 5.iii. How can I use ALE and coc.nvim together?
-
-[coc.nvim](https://github.com/neoclide/coc.nvim) is a popular Vim plugin written
-in TypeScript and dependent on the [npm](https://www.npmjs.com/) ecosystem for
-providing full IDE features to Vim. Both ALE and coc.nvim implement
-[Language Server Protocol](https://microsoft.github.io/language-server-protocol/)
-(LSP) clients for supporting diagnostics (linting with a live server), and other
-features like auto-completion, and others listed above.
-
-ALE is primarily focused on integrating with external programs through virtually
-any means, provided the plugin remains almost entirely written in Vim script.
-coc.nvim is primarily focused on bringing IDE features to Vim. If you want to
-run external programs on your files to check for errors, and also use the most
-advanced IDE features, you might want to use both plugins at the same time.
-
-The easiest way to get both plugins to work together is to configure coc.nvim to
-send diagnostics to ALE, so ALE controls how all problems are presented to you,
-and to disable all LSP features in ALE, so ALE doesn't try to provide LSP
-features already provided by coc.nvim, such as auto-completion.
-
-1. Open your coc.nvim configuration file with `:CocConfig` and add
-   `"diagnostic.displayByAle": true` to your settings.
-2. Add `let g:ale_disable_lsp = 1` to your vimrc file, before plugins are
-   loaded.
-
-You can also use `b:ale_disable_lsp` in your ftplugin files to enable or disable
-LSP features in ALE for different filetypes. After you configure coc.nvim and
-ALE this way, you can further configure how problems appear to you by using all
-of the settings mentioned in ALE's help file, including how often diagnostics
-are requested. See `:help ale-lint`.
-
-The integration between ALE and coc.nvim works using an API ALE offers for
-letting any other plugin integrate with ALE. If you are interested in writing a
-similar integration, see `:help ale-lint-other-sources`.

 `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.

-ALE will attempt to parse `compile_commands.json` files to discover compiler
-flags to use when linting code. See `:help g:ale_c_parse_compile_commands` for
-more information. See Clang's documentation for
-[compile_commands.json files](https://clang.llvm.org/docs/JSONCompilationDatabase.html).
-You should strongly consider generating them in your builds, which is easy to do

-You can also configure ALE to automatically run `make -n` to run dry runs on

 You may also configure buffer-local settings for linters with project-specific
 vimrc files. [local_vimrc](https://github.com/LucHermitte/local_vimrc) can be
