This template should be used on Wikipedia tools (such as Twinkle) to advise people to use it with caution. Add it as {{tool warning|Name of tool}}, using the parameter if the {{ROOTPAGENAME}} is not the correct title.

You can also align this template by using |align=alignment, replacing alignment with left, right, or center (default). If you only wish to change the text alignment, use |textalign=text alignment.

An |access= parameter is allowed; setting this to any value will add, "or risk losing access to the tool" to the last sentence, intended for tools that utilize a blacklist for banned users or a whitelist for permitted users.
