 ## Build instructions
 We are using Waf build system. If you have some Waf-related questions, I recommend you to read https://waf.io/book/
 
-1) Clone this repository: `git clone --recursive https://github.com/FWGS/xash3d-fwgs`
+If you're stuck somewhere and you need a clear example, open `.travis.yml`. 
-2) Examine which build options are available: `waf --help`
+
-3) Configure build: `waf configure`
+### Prerequisites
+#### Windows(Visual Studio)
+* Install Visual Studio.
+* Install latest [Python](https://python.org) *OR* run `cinst python.install` if you have Chocolatey.
+* Install latest [Git](https://git-scm.com/download/win) *OR* run `cinst git.install` if you have Chocolatey.
+* Download [SDL2](https://libsdl.org/download-2.0.php) development package for Visual Studio.
+* Clone this repository: `git clone --recursive https://github.com/FWGS/xash3d-fwgs`.
+* Clone `vgui-dev` repository: `git clone https://github.com/FWGS/vgui-dev`.
+* Make sure you have at least 12GB of free space to store all build-time dependencies: ~10GB for Visual Studio, 300 MB for Git, 100 MB for Python and other.
+
+#### Linux
+NOTE: Make sure you're OK with targetting 32-bit.
+Even if Xash3D FWGS does support targetting 64-bit, anything can happen, not to mention that you can't load games without recompiling them from source code!
