 We adhere to the [keepachangelog](https://keepachangelog.com/en/1.0.0/) format (starting after version `1.27.0`).
 
 ## [Unreleased]
+### Added
+* Tsfmt Maven Plugin ([#548](https://github.com/diffplug/spotless/pull/548))
 ### Fixed
 * Eclipse-WTP formatter (web tools platform, not java) handles some character encodings incorrectly on OS with non-unicode default file encoding [#545](https://github.com/diffplug/spotless/issues/545). Fixed for Eclipse-WTP formatter Eclipse version 4.13.0 (default version).

 Use the Eclipse to define the *Code Style preferences* (see [Eclipse documentation](https://www.eclipse.org/documentation/)). Within the preferences *Edit...* dialog, you can export your configuration as XML file, which can be used as a configuration `<file>`. If no `<file>` is provided, the CDT default configuration is used.

+## Applying to Typescript source

+```xml
+<configuration>
+  <typescript>
+     <tsfmt>
+       <!-- optionally define which files will be formatted. -->
+       <includes>
+         <include>src/**/*.ts</include> <!-- default value if nothing is specified -->

+       <tslintVersion>5.12.1</tslintVersion>
+     </tsfmt>
+  </typescript>
+</configuration>
+```
+
+Supported config file types are `tsconfigFile`, `tslintFile`, `vscodeFile` and `tsfmtFile`. They are corresponding to the respective
+[tsfmt-parameters](https://github.com/vvakame/typescript-formatter/blob/7764258ad42ac65071399840d1b8701868510ca7/lib/index.ts#L27L34).  See [tsfmt's default config settings](https://github.com/vvakame/typescript-formatter/blob/7764258ad42ac65071399840d1b8701868510ca7/lib/utils.ts#L11L32) for what is available.
+
+*Please note:*
+The auto-discovery of config files (up the file tree) will not work when using tsfmt within spotless,
+  hence you are required to provide resolvable file paths for config files.
+
+### Prerequisite: tsfmt requires a working NodeJS version
+
+tsfmt is based on NodeJS, so to use it, a working NodeJS installation (especially npm) is required on the host running spotless.
+Spotless will try to auto-discover an npm installation. If that is not working for you, it is possible to directly configure the npm binary to use.
+
+```xml
+<configuration><typescript><tsfmt>
+  ...
+  <npmExecutable>/usr/bin/npm</npmExecutable>
+```
+
+Spotless uses npm to install necessary packages locally. It runs tsfmt using [J2V8](https://github.com/eclipsesource/J2V8) internally after that.
