+# Ds4Vita-Unofficial_Mod
+A custom version for Xerpi's ds4vita: https://github.com/xerpi/ds4vita
+
+**Enable the plugin:**
+
+1. Add ds4vita.skprx to taiHEN's config (ux0:/tai/config.txt):
+	```
+	*KERNEL
+	ux0:tai/ds4vita.skprx
+	```
+2. You need to refresh the config.txt by rebooting or through VitaShell.
+
+**Using it for the first time (pairing the controller):**
+
+1. Go to Settings -> Devices -> Bluetooth Devices
+2. Press SHARE+PS on the DS4 for about 3-4 seconds, until the lightbar blinks very quickly
+3. The DS4 will then connect and be paired (don't press over it when it appears)
+
+**Using it once paired (see above):**
+1. Just press the PS button and it will connect to the Vita
+
+**Note**: If you use Mai, don't put the plugin inside ux0:/plugins because Mai will load all stuff you put in there...
