-L<lei-init(1)> initializes writable local storage based on
-L<public-inbox-v2-format(5)>.
+lei has writable local storage based on L<public-inbox-v2-format(5)>.
+Commands will automatically initialize the store behind the scenes if
+needed, but you can call L<lei-init(1)> directly if you want to use a
+store location other than the default C<$XDG_DATA_HOME/lei/store>.
+
+The L<lei-import(1)> command provides the primary interface for
+importing messages into the local storage.  In addition, other
+commands, such as L<lei-q(1)> and L<lei-blob(1)>, use the local store
+to memoize messages from remotes.
 
 =head2 EXAMPLES
 
 =over
 
-=item $ lei import mboxrd:t.mbox
+=item $ lei import mboxrd:t.mbox.gz
+
+Import the messages from a gzipped mboxrd into the local storage.
+
+=item $ lei blob 59ec517f9
 
-Import the messages from an mbox into the local storage.
+Show message with the git blob OID of 59ec517f9.  If a message with
+that OID isn't found, check if the current git repository has the
+blob, trying to reconstruct it from a message if needed.
+
+=item $ lei blob 59ec517f9 | lei tag -F eml +kw:flagged +L:next
+
+Set the "flagged" keyword and "next" label on the message with the
+blob OID of 59ec517f9.

+=head1 PERFORMANCE NOTES
+
+L<Inline::C> is required, lei runs as a background daemon to reduce
+startup costs and can provide real-time L<kqueue(2)>/L<inotify(7)>
+Maildir monitoring.  L<IO::KQueue> (p5-IO-KQueue on FreeBSD) and
+L<Linux::Inotify2> (liblinux-inotify2-perl and perl-Linux-Inotify2 in
+.deb and .rpm-based distros, respectively) are recommended.
+
+L<Socket::MsgHdr> is optional (libsocket-msghdr-perl in Debian),
+and further improves startup performance.  Its effect is most felt
+when using shell completion.
+
+=head1 BASH COMPLETION
+
+Preliminary Bash completion for lei is provided in
+C<contrib/completion/>.  Contributions adding support for other
+shells, as well as improvements to the existing Bash completion, are
+welcome.
+
+=head1 UPGRADING
+
+Since lei runs as a daemon, L<lei-daemon-kill(1)> is required to kill
+the daemon so it can load new code.  It will be restarted with the
+next invocation of any lei command.
+
+=head1 CAVEATS
+
+IMAP and NNTP client performance is poor on high-latency connections.
+It will hopefully be fixed in 2022.
