• Most websites name the docs landing page simply Documentation or even Docs. Currently, the title is "The etcd documentation" -- given that this is the etcd website, there is an overemphasis here.
• Similar remarks apply to the landing page for each version of the docs

This redundancy / overemphasis will become even more obvious with breadcrumbs under the docsy theme, that will read something like:

• The etcd documentation / etcd version 3.4 / ...

IMHO, this could more simply be:

• Docs / v3.4 / ...

(which will be even more significant as we get down into the doc tree).
