 I recommend just copying (or symlink) the uECC files into your project. Then just `#include "uECC.h"` to use the micro-ecc functions.
 
-For use with Arduino, you can just create a symlink to the `uECC` directory in your Arduino `libraries` directory. You can then use uECC just like any other Arduino library (uECC should show up in the **Sketch**=>**Import Library** submenu).
+For use with Arduino, you can use the Library Manager to download micro-ecc (**Sketch**=>**Include Library**=>**Manage Libraries**). You can then use uECC just like any other Arduino library (uECC should show up in the **Sketch**=>**Import Library** submenu).
 
 See uECC.h for documentation for each function.
