+Removed deprecated api endpoints:

+- `getLanguage` - Replaced by `createQuery`
+- `getNodeAtLocation` - No direct replacement. Use scm queries and `createQuery` instead.

-### Parsing a custom language
-
-If you'd like to add support for a new language, see the [Adding a new language](#adding-a-new-language) section below. Alternatively, your extension can register a custom language with this extension. Although this is not the preferred way to add a new language, it can be convenient when you have a parser that you don't believe belongs in the main extension.
-
-Parsing your own language is as simple as registering your `languageId` with an absolute path to your `.wasm` file:
-
-```ts
-const { registerLanguage } = await parseTreeExtension.activate();
-
-registerLanguage(languageId, wasmPath);
-```

 It's straightforward to add any [language with a tree-sitter grammar](https://tree-sitter.github.io/tree-sitter/).
 
 1. Add a dependency on the npm package for that language in [tree-sitter-wasms](https://github.com/cursorless-dev/tree-sitter-wasms)
-2. Add a language to the dictionary at the top of `./src/extension.ts`
+2. Add a language to the map in [`languages.ts`](./src/languages.ts)
 3. Add a reference to `onLanguage:yourlang` to the [activationEvents section of package.json](package.json). `yourlang` must be a [VSCode language identifier](https://code.visualstudio.com/docs/languages/identifiers).
 4. Run `npm install` and `npm run compile`, then hit `F5` in VSCode, with this project open, to test your changes.
