-# Adding languages
+# Adding new languages to Helix
+
+In order to add a new language to Helix, you will need to follow the steps
+below.
 
 ## Language configuration
 
-To add a new language, you need to add a `[[language]]` entry to the
-`languages.toml` (see the [language configuration section]).
+1. Add a new `[[language]]` entry in the `languages.toml` file and provide the
+   necessary configuration for the new language. For more information on
+   language configuration, refer to the
+   [language configuration section](../languages.md) of the documentation.
+2. If you are adding a new language or updating an existing language server
+   configuration, run the command `cargo xtask docgen` to update the
+   [Language Support](../lang-support.md) documentation.
 
-When adding a new language or Language Server configuration for an existing
-language, run `cargo xtask docgen` to add the new configuration to the
-[Language Support][lang-support] docs before creating a pull request.
-When adding a Language Server configuration, be sure to update the
-[Language Server Wiki][install-lsp-wiki] with installation notes.
+> 💡 If you are adding a new Language Server configuration, make sure to update
+> the
+> [Language Server Wiki](https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers)
+> with the installation instructions.
 
 ## Grammar configuration
 
-If a tree-sitter grammar is available for the language, add a new `[[grammar]]`
-entry to `languages.toml`.
-
-You may use the `source.path` key rather than `source.git` with an absolute path
-to a locally available grammar for testing, but switch to `source.git` before
-submitting a pull request.
+1. If a tree-sitter grammar is available for the new language, add a new
+   `[[grammar]]` entry to the `languages.toml` file.
+2. If you are testing the grammar locally, you can use the `source.path` key
+   with an absolute path to the grammar. However, before submitting a pull
+   request, make sure to switch to using `source.git`.
 
 ## Queries
 
-For a language to have syntax-highlighting and indentation among
-other things, you have to add queries. Add a directory for your
-language with the path `runtime/queries/<name>/`. The tree-sitter
-[website](https://tree-sitter.github.io/tree-sitter/syntax-highlighting#queries)
-gives more info on how to write queries.
-
-> NOTE: When evaluating queries, the first matching query takes
-precedence, which is different from other editors like Neovim where
-the last matching query supersedes the ones before it. See
-[this issue][neovim-query-precedence] for an example.
-
-## Common Issues
-
-- If you get errors when running after switching branches, you may have to update the tree-sitter grammars. Run `hx --grammar fetch` to fetch the grammars and `hx --grammar build` to build any out-of-date grammars.
-
-- If a parser is segfaulting or you want to remove the parser, make sure to remove the compiled parser in `runtime/grammar/<name>.so`
