This project makes a Raspberry Pi pretend to act as a WiFi hotspot with a captive portal. It does not actually provide an internet connection to connected clients, but simply triggers their captive portal detection, which causes them to present users with a browser window containing content of your choosing.
I created this for security tinkering purposes, but also because I found the documentation for similar projects lacking. I've attempted to document and explain the salient points of the entire Raspberry Pi Linux configuration relating to the captive portal.
