+#### Add support for TypeScript config files (#16828 by @itsyoboieltr & @fisker)
+
+Added new format of configuration files:
+
+- `.prettierrc.ts`
+- `.prettierrc.mts`
+- `.prettierrc.cts`
+- `prettier.config.ts`
+- `prettier.config.mts`
+- `prettier.config.cts`
+
+Note:
+
+Currently TypeScript support in Node.js is experimental.
+
+To make TypeScript config files work, Node.js>=22.6.0 is required and `--experimental-strip-types` is required to run Node.js.
+
+You can run prettier with
+
+```sh
+node --experimental-strip-types node_modules/prettier/bin/prettier.cjs . --write
+```
+
+or
+
+```sh
+NODE_OPTIONS="--experimental-strip-types" prettier . --write
+```
+
+Other TS loaders should also work, but not tested, use at your own risk.
+
+For example, with [`tsx`](https://tsx.is/), you can
+
+```sh
+node --import tsx node_modules/prettier/bin/prettier.cjs . --write
+```
+
+or
+
+```sh
+tsx node_modules/prettier/bin/prettier.cjs . --write
+```

+> TypeScript configuration files support requires [additional setup](#typescript-configuration-files)
+
 The configuration file will be resolved starting from the location of the file being formatted, and searching up the file tree until a config file is (or isn’t) found.
 
 Prettier intentionally doesn’t support any kind of global configuration. This is to make sure that when a project is copied to another computer, Prettier’s behavior stays the same. Otherwise, Prettier wouldn’t be able to guarantee that everybody in a team gets the same consistent results.
 
 The options you can use in the configuration file are the same as the [API options](options.md).
