To download/install software, one usually has to have privileges of the root user. This is often not permitted by admins or some systems, so people use "sudo" to work around this when installing software.

For the Broker (section 2.3) and Interconnect (section 2.2) installation sections, we need to add a note about the use of sudo. Particularly note that one should exercise caution when you have sudo'd since you can make changes to the entire system.

Also verify with clients dev that his note is NOT needed for clients. I see no references to sudo in a prelim search.

We could consider adding a pointer here for more info:
