+# Windows 98 SE DOS Mode
+Configuration and tools for Windows 98 SE DOS Mode. Created as an extension of the setup described by user [Nevets](https://www.youtube.com/channel/UC1TcLr9bclCxgpZ6kxj5Mpg) on YouTube (see [video 1](https://www.youtube.com/watch?v=HOXqgALpn9A), [video 2](https://www.youtube.com/watch?v=zWMJ3T8c2Us)).
+
+## Features
+
+- Start menu offering options to boot *Windows 98 SE*, *DOS Mode* and *DOS Mode with CD-ROM drivers*
+- Very memory-efficient mouse and CD-ROM drivers
+- CPU idle drivers
+- Script to conveniently edit *MSDOS.SYS*
+- Utilities to restart and shutdown system
+
+## Download
+Refer to the [releases](https://github.com/fonic/windows-98-se-dos-mode/releases) section for downloads links.
+
+## Installation
+1. Either extract the downloaded ZIP archive or mount the downloaded ISO using VirtualBox
+2. Change to the folder containing `INSTALL.BAT` (e.g. `CD D:\` if ISO was mounted as drive D)
+3. Run `INSTALL.BAT`
+
+Your existing configuration and tools will be backed up to `.BAK` files/folders.
