 the options defaulted.
 
+`:VimspectorUpdate` runs `install_gadget.py` to re-install (i.e. update) any
+gadgets already installed in your `.gadgets.json`.
+
+The output is minimal, to see the full output add `--verbose` to the command, as
+in `:VimspectorInstall --verbose ...`  or `:VimspectorUpdate --verbose ...`.
+
+If the installation is successful, the output window is closed (and the output
+lost forever). Use a `!` to keep it open (e.g. `:VimspectorInstall! --verbose
+--all` or `:VimspectorUpdate!` (etc.).

+### install\_gadget.py

 By default `install_gadget.py` will overwrite your `.gadgets.json` with the set
 of adapters just installed, whereas `:VimspectorInstall` will _update_ it,
 overwriting only newly changed or installed adapters.
