 ### This is the *old* 3.x branch of the project, with Face Recognition, but no Over The Air updates
 I will continue to fix bugs as needed on this branch for the forseeable future, but will not be adding any new features

Face Recognition features of the camera module.

 ### Download the Sketch, Unpack and Rename
-Download the latest release of the sketch from https://github.com/easytarget/esp32-cam-webserver/releases/latest
-- You can get the latest stable development release by cloning / downloading the `master` branch of the repo.

Tou need to unpack this into your Arduino sketch folder, and then you need to rename the folder you just extracted to remove the version number, eg.`esp32-cam-webserver-3.0` becomes `esp32-cam-webserver`.
