Unzip and then double click to run. You'll be prompted for the info that's needed.. You can easily change the defaults by running --help and using the flags.

Supports:

• Raspberry Pi (iw and iwlist)
• Windows
• Linux

Bug fixes:

• Can switch to iwlist if iw is not available (linux only) using --iwlist (issue #42, #62 )
• Alternative 3rd-party Windows scanner available thanks to ScottSWu (issue #40)
• Will rest if interface gets confused (issue #29)
