 My submission is an android app, so you will need to install it on an android phone to test it.
 
 ### How to Install Humanly Random:
-- Enable developer mode on your android phone
-  If you're not sure how to do this, see: https://developer.android.com/studio/debug/dev-options
-- navigate to https://bit.ly/HumanlyRandom and download the .apk file
+- Go to your settings --> lock screen and security, and enable Unknown Sources
+  (This allows the app to be installed through Google Drive)
+  If you can't find the option see this article: 
+  https://www.technipages.com/where-did-allow-installation-from-unknown-sources-go-in-android
+- navigate to bit.ly/HumanlyRandom and download the .apk file
+  (This is a Google Drive short-link so you might need to log in to download the file)
 - Open the downloaded package file with Android's Package Installer
 - You should get a screen asking if you'd like to install the app, press install
 - You might get asked if you would like to scan the app with google play
