Description

Adds some instructions regarding the local destination of the cloned repo, in order to avoid possible issues with cloning the repo to a folder whose absolute path contains a space character (example in this mattermost thread).

In general I'm wary of adding too much specific detail to the "Quickstart" set-up docs, as we have to assume that users either have some level of technical proficiency or can acquire it elsewhere. However, it does seem worth including instructions such as this where there might otherwise be issues for some users that do not make themselves immediately apparent.

This diff was changing PyYAML==6.0 -> PyYAML==6.0.2. PyYAML v6.0 was not installing for me, but updating the dependency to the most recent version fixed the issue.
