 ## Installation and Use
 
 Currently, we officially support only Windows and Linux. It may be possible to build macOS version from the sources, but since we do not own a macOS version of IDA, we cannot create a pre-built package, or continually make sure the macOS build is not broken.
 
-### Windows
-
-1. Either download and unpack a pre-built package from the following list, or build and install the RetDec IDA plugin by yourself (the process is described below):
-
-    * [Windows - for 64-bit IDA](https://github.com/avast-tl/retdec-idaplugin/releases/download/v0.8/retdec-idaplugin-v0.8-windows.zip) (v0.8)
-
-2. Follow the user guide (`user_guide.pdf`) that is part of the downloaded package, or use the [current version](https://github.com/avast-tl/retdec-idaplugin/blob/master/doc/user_guide/user_guide.pdf) from this repository.
