+# Tablet
+
+Since Windows 8, Microsoft introduced a new API to use your tablet
+with Windows program: the pointer API. Since Aseprite v1.2.19.1 you
+can configure what API do you prefer to use:
+
+![Tablet section](tablet/tablet.png)
+
+* *Windows 8/10 Pointer API*: This option might be enough for most
+  modern devices, you can give a try how your tablet works with this
+  (might work better with this option than with Wintab)
+* *[Wintab](wintab.md)*: This is the default option at the moment to
+  support pressure sensitivity on older systems (Windows Vista/7) and
+  older devices.
+* *Wintab (direct packet processing)*: This option might not work well
+  in some devices, but might be useful in other devices to avoid
+  losing packets and getting smoother strokes.
+
+Pressing the *OK*/*Apply* buttons will change the tablet settings
+immediately, there is no need to restart the program.

+# Wintab
+
+Wintab (`WinTab32.dll`) is an ancient API created by Wacom to
+communicate tablet-like devices with Windows programs. Before Windows 8,
+this was the "de facto" standard used to access pressure
+information from tablets created by Wacom and other brands. Since
+Windows 8, Microsoft introduced a new official API: the Pointer
+API/Windows Ink.
+
+Sometimes, when we load this DLL the program just hangs or doesn't
+work properly. You might solve this reinstalling drivers or restarting
+Windows. If the problem persists one first attempt would be to use the
+Pointer API from [Tablet options](tablet.md), or disabling Wintab
+usage from *Edit > Preferences > Tablet* (or *Edit > Preferences >
+Experimental* in old versions):

+## Aseprite doesn't start
+
 If you cannot even start the program, you can execute Aseprite with
 the `-disable-wintab` parameter (available since Aseprite v1.2):
 
     "C:\Program Files\Aseprite\Aseprite.exe" -disable-wintab
 
-This will bypass the `WinTab32.dll` loading process. Your stylus might
-not work correctly, but at least Aseprite can be executed and used
-with your mouse/trackpad.
+This will avoid loading `WinTab32.dll` file. Your tablet might not

+your mouse/trackpad (or again, you can try the [Windows Pointer API](tablet.md)).
