+# Environmental Cheminformatics Educational Platform: Plan B
+
+This repository contains a collection of ansible scripts which can be
+used to provision an Ubuntu/Debian based virtual machine in a public
+cloud. The scripts have been written for a specific Digital Ocean
+_droplet_, but can easily be adapted for something else.
+
+
+## Access
+
+The desktop environment on the compute node *alien-one* is accessible
+through VNC protocol. Any VNC viewer can be used. If in doubt, try the
+cross-platform TigerVNC_ viewer [available from here for
+Windows](https://bintray.com/tigervnc/stable/download_file?file_path=vncviewer-1.11.0.exe),
+or as a package from your GNU/Linux distribution.
+
+
+
+**Before connecting, you need: 
+	- A X509 certificate file.
+	- The IP address of the server.
+	- Your username and password.**
+
+### Connection instructions
+
+1. Open the VNC viewer.
+2. Click `Options`.
+3. Switch to `Security` tab.
+4. Make sure that at least `TLS with X509 certificates` is checked.
+5. Make sure that at least `None` is checked in the `Authentication` section.
+6. Set the `Path to X509 certificate` to the location of the X509
+   certificate file.
+7. Now, click `OK` to accept changes and close the `Options` tab.
+8. Fill in the IP address of the server in field `VNC server` and
+   append `:5950` to it. So, the `VNC server` entry should look like
+   this `XXX.XXX.XXX.XXX:5950`.
+9. Click `Connect`.
