[stemlock]

• Include some examples that show you can perform commands (e.g,. mv, cp, ls) from a higher level directories by adding in the relative path (e.g., ls solutions/)
• 'less' command is not available on DataHub, so some questions were asked about why it wasnt working. Might want to add a disclaimer or change this to something else
• We may also want to include echo commands as a form of writing to file
