+# Driver for IIDX BIO2
+Currently, this package offers drivers for the following platforms:
+* Windows 7: x64 (confirmed to work on Windows 10)
+
+### Install
+* Plug in the device and Windows should recognize it automatically
+* Windows will install a default driver that works fine when using
+BT5's bio2 driver, e.g. `iidxio-bio2.dll`. However, if you want
+to use the BIO2 with any version starting 25 without BT5 or its
+emulation layer, the board cannot be detected resulting in an IO
+error (due to a mismatch in the drivers name).
+* Go to the device manager, select the COM port the BIO2 is enumerated
+as -> Right click -> "Update driver"
+* "Browse my computer for driver software" -> Next
+* "Let me pick from a list of device drivers on my computer" -> Next
+* "Have Disk..." -> "Browse..." -> Select the driver inf file
+* Select the device "KAM BIO2(VIDEO) CDC DRIVER" from the list -> 
+Next
+* That should be it
+
+## Testing
+Instead of using the games, use one of the tools included with BT5 to test and
+debug issues as it will error on more fine granular level. Furthermore, you
+can also check the source code for details and to track down any unknown issues.
