 ### Windows - Build Packages and Installer
 
-Building of Datovka installer for Windows requires:
+#### Since Datovka-4.11.1
+
+We've modified the building procedure of the application since the version 4.11.1.
+
+##### Building Required Libraries
+
+In order to build all required third-party libraries you need to use a working MinGW toolchain. We are using MinGW on Ubuntu 16.04. Navigate to the application repository and run the following command:
+
+``` shell
+./scripts/build_libisds_mingw.sh
+```
+
+This will download and build all required libraries inside the directory `libs/shared_built/`. It will also create an `shared_built_DATE_UTCTIME_.tar.gz` archive inside `libs/` containing the built libraries.
+
+Copy the archive into a Windows environment where the compilation procedure continues.
+
+#### Preparing Windows Environment
+
+#### Before Datovka-4.11.1

 * Windows 7 or later
-* Qt5.2.1 or newer
+* Qt-5.3.2 or newer
