+## How to run Gazebo with remote 3D rendering
+1. make sure that the remote machine has VirtualGL and a TurboVNC installed
+2. ssh to the remote machine
+3. start the vncserver:
+```shell
+vncserver :10 #10 is the display number. Any free display number will do.
+```
+4. start a VNC session from the local machine to the display #10 of the remote machine:
+```shell
+vncviewer <remote hostname>:10
+```
+5. start a shell in the remote machine
+6. launch gazebo with VirtualGL:
+```shell
+vglrun ./start_gazebo.sh
+```
+
+## How to run gzweb (web client for Gazebo)
+1. start gzserver+gzweb on the machine with Gazebo installed:
+```shell
+./start_gzweb.sh
+```
