 # Change Log
 
+## [2.1.0] - 2019-07-31
+
+* Added basic support for mounting CASC as filesystem visible to the OS using [FUSE](https://github.com/libfuse/libfuse).
+  * Linux will work out of the box.
+  * MacOS is likely to work but hasn't been tested.
+  * Under Windows app is compiled against `dokanfuse` wrapper library. In order for it to work `Dokany` must be installed on the system.
+
 ## [2.0.0] - 2019-07-26
 
 * Refactored entire codebase..

+##### Windows support via Dokany
+
+[Dokany](https://github.com/dokan-dev) provides a FUSE wrapper for Windows. You've to install [Dokany's system driver](https://github.com/dokan-dev/dokany/wiki/Installation) in order for this feature to work.
+
+As `[MOUNTPOINT]` argument provide a free drive letter. In following example CASC will be mounted at `S:\`.
+
+```sh
+stormex.exe -v -S X:\shared\SC2.4.8.4.73286 -m S
+```
