# Getting Help

xyscan comes with an detailed documentation. A simple help browser allows to navigate through the documentation - the one you are using right now. You can launch the browser and view the documentation at any time using `Help->Documentation`.

At the beginning it is also helpful to enable Tool Tips (is on by default). If enabled, rest with you mouse over an active element of the user interface and a small text window will pop up telling you what the specific widget does and what it is good for. Once you get more familiar with the program Tool Tips can become annoying. You can switch them off (and back on) at any time using the `Help->Tool Tips` menu item. xyscan remembers your settings.

If you have problems with xyscan it is worth checking for updates. This can be done using the `Help->Check for Updates` menu item. This feature is still in the experimental phase and might not work on all systems when you connect to the internet through a proxy.
