+# Prerequisites
+
+XDS is written in Go and currently only build on Linux host has been validated.
+
+So to build XDS binaries you need to install first [Go](https://golang.org/doc/install)
+version 1.8.1 or higher and some other tools. To build `xds-server` and `xds-agent`
+you also need to install in addition `nodejs` and `python3` tools.
+
+**Ubuntu:**
+
+```bash
+# Install various tools
+sudo apt-get install git make npm curl git zip unzip wget
+
+# Install Go
+source /etc/os-release
+wget -O - "http://keyserver.ubuntu.com/pks/lookup?op=get&search=0x52B59B1571A79DBC054901C0F6BC817356A3D45E" | sudo apt-key add -
+sudo bash -c "cat >> /etc/apt/sources.list.d/golang.list <<EOF
+deb http://ppa.launchpad.net/longsleep/golang-backports/ubuntu ${VERSION_CODENAME} main
+EOF"
+sudo apt-get update
+sudo apt-get install golang-go
+
+# Install python3
+sudo apt-get install python3
+```
+
+**openSUSE:**
+
+```bash
+# Install various tools
+sudo zypper install git make npm curl zip unzip
+
+# Install Go
+# ( the value 'DISTRO' can be set to {openSUSE_Leap_42.2, openSUSE_Leap_42.3, openSUSE_Tumbleweed} )
+source /etc/os-release; export DISTRO="openSUSE_Leap_$VERSION"
+sudo zypper ar http://download.opensuse.org/repositories/devel:/languages:/go/${DISTRO}/devel:languages:go.repo
+sudo zypper --gpg-auto-import-keys ref
+sudo zypper install go1.9
+
+# Install python3
+sudo zypper install python3
+```
+
+> Don't forget to open new user session after installing these packages.
+
+**All Linux distro:**
+
+```bash
+# Install nodejs LTS version (only mandatory for xds-server and xds-agent)
+sudo npm install --global n
+sudo n lts
+```
+
+Angular developers that's plan to modify XDS Dashboard webapp (part of
+`xds-agent` repo) may also need angular cli tool named `ng` :
+
+```bash
+# Install angular cli tool (ng)
+sudo npm install --global n @angular/cli
+```
