 ### CMake as most universal way
 
-```
     mkdir build && cd build
     cmake ../
-```
+    make
 
 You may enable or disable some build options by -Dkey=value. All available build options are defined in CMakeLists.txt at root directory.
+See below if you want to build the GoldSource compatible libraries.
 
 See below, if CMake is not suitable for you:
 
 ### Windows
 
+#### Using msvc
+
+We use compilers provided with Microsoft Visual Studio 6. There're `compile.bat` scripts in both `cl_dll` and `dlls` directories.
+Before running any of those files you must define `MSVCDir` variable which is the path to your msvc installation.
+
+    set MSVCDir=C:\Program Files\Microsoft Visual Studio
+    compile.bat
+
+These scripts also can be ran via wine:
+
+    MSVCDir="z:\home\$USER\.wine\drive_c\Program Files\Microsoft Visual Studio" wine cmd /c compile.bat
+
+The libraries built this way are always GoldSource compatible.
+
+There're dsp projects for MVS 6 in `cl_dll` and `dlls` directories, but we don't keep them up-to-date. You're free to adapt them for yourself and try to import into the newer MVS versions.

+
+### Building GoldSource-compatible libraries
+
+To enable building the goldsource compatible client library add GOLDSOURCE_SUPPORT flag when calling cmake:
+
+    cmake .. -DGOLDSOURCE_SUPPORT=ON
+
+or when using make without cmake:
+
+    make GOLDSOURCE_SUPPORT=1
+
+Unlike original client by Valve the resulting client library will not depend on vgui or SDL2 just like the one that's used in FWGS Xash3d.
+
+Note for **Linux**: GoldSource requires libraries (both client and server) to be compiled with libstdc++ bundled with g++ of major version 4 (versions from 4.6 to 4.9 should work).
+If your Linux distribution does not provide compatible g++ version you have several options.
+
+#### Method 1: Statically build with c++ library
+
+This one is the most simple but has a drawback.
+
+    cmake ../ -DGOLDSOURCE_SUPPORT=ON -DCMAKE_C_FLAGS="-static-libstdc++ -static-libgcc"
+
+The drawback is that the compiled libraries will be larger in size.
+
+#### Method 2: Build in Steam Runtime chroot
+
+This is the official way to build Steam compatible games for Linux.
+
+Clone https://github.com/ValveSoftware/steam-runtime and follow instructions https://github.com/ValveSoftware/steam-runtime#building-in-the-runtime
+
+    sudo ./setup_chroot.sh --i386
+
+Then use cmake and make as usual, but prepend the commands with `schroot --chroot steamrt_scout_i386 --`:
+
+    mkdir build-in-steamrt && cd build-in-steamrt
+    schroot --chroot steamrt_scout_i386 -- cmake ../ -DGOLDSOURCE_SUPPORT=ON
+    schroot --chroot steamrt_scout_i386 -- make
+
+#### Method 3: Create your own chroot with older distro that includes g++ 4.
+
+Use the most suitable way for you to create an old distro 32-bit chroot. E.g. on Debian (and similar) you can use debootstrap.
+
+    sudo debootstrap --arch=i386 jessie /var/chroot/jessie-debian-i386 # On Ubuntu type trusty instead of jessie
+    sudo chroot /var/chroot/jessie-debian-i386
+
+Inside chroot install cmake, make, g++ and libsdl2-dev. Then exit the chroot.
+
+On the host system install schroot. Then create and adapt the following config in /etc/schroot/chroot.d/jessie.conf (you can choose a different name):
+
+```
+[jessie]
+type=directory
+description=Debian jessie i386
+directory=/var/chroot/debian-jessie-i386/
+users=yourusername
+groups=yourusername
+root-groups=root
+preserve-environment=true
+personality=linux32
+```
+
+Insert your actual user name in place of `yourusername`. Then prepend any make or cmake call with `schroot -c jessie --`:
+
+    mkdir build-in-chroot && cd build-in-chroot
+    schroot --chroot jessie -- cmake ../ -DGOLDSOURCE_SUPPORT=ON
+    schroot --chroot jessie -- make
+
+#### Method 4:  Install the needed g++ version yourself
+
+TODO: describe steps.
+
+#### Configuring Qt Creator to use toolchain from chroot
+
+Create a file with the following contents anywhere:
+
+```sh
+#!/bin/sh
+schroot --chroot steamrt_scout_i386 -- cmake "$@"
+```
 
+Make it executable.
+In Qt Creator go to `Tools` -> `Options` -> `Build & Run` -> `CMake`. Add a new cmake tool and specify the path of previously created file.
+Go to `Kits` tab, clone your default configuration and choose your CMake tool there.
+Choose the new kit when opening CMakeLists.txt.
