The Before you Begin/What Do You Need section doesn't make it clear that you need either PuTTY or ssh-keygen (rather than both): - Both are listed as bullet points, and in the Before starting this tutorial section, both are again listed as bullets - There's a bullet with the text 'Some knowledge of UNIX, for working at the command line'. that does not exclude Windows users. I'd suggest making the distinction clearer in the Background or Scenario sections, and separating the What Do You Need section based on which operating system the user needs, and making that choice obvious in the section title headings beneath. See here for an example of such separation: http://docs.oracle.com/en/cloud/paas/java-cloud/jscug/generate-ssh-key-pair.html#GUID-69EF7E8A-7CD5-482E-A878-882EA21DE2B8

Thanks much, it is a verry uncomplex straight forward howto. Worked verry well!!
