 You must have a closing `</body>` tag for LiveReload to work.
 Hugo injects the LiveReload `<script>` before this tag.

-Hugo's "`--watch`" option will monitor the content/ and your theme directories for changes and rebuild the site automatically. Since version 0.15, this has been the default option for `hugo server`.
+Hugo's watch functionality monitors the relevant site and theme directories

+By default, watching is

+In some use cases,
+Hugo's web site generator should watch—simply
+type `hugo --watch` on the command line.

+Sometimes with Docker containers (and Heroku slugs),
+the site sources may live on a read-only filesystem.
+In that scenario, it makes no sense
+for Hugo's web server to watch for file changes—so
+use `hugo server --watch=false`.
