 A VSCode extension to keep XLIFF translation files in sync with a specified, automatically generated base-XLIFF file.
 
+**Update**: There is now also an ["XLIFF Sync" PowerShell module](https://github.com/rvanbekkum/ps-xliff-sync)!
+
 This project originated from the need for a tool to automatically merge/synchronize XLIFF translation files that are in the OASIS specification.
 This extension is based on the [Angular Localization Helper](https://github.com/manux54/vsc-angular-localization-helper) developed by [manux54](https://github.com/manux54), which has been extended so that it can also be used to synchronize files from other XLIFF generators.
 It is specifically targeted at synchronizing trans-units from an `<ApplicationName>.g.xlf` file automatically generated by the [AL Language](https://marketplace.visualstudio.com/items?itemName=ms-dynamics-smb.al) extension that can be used to develop extensions for Microsoft Dynamics 365 Business Central.
