This is part of [Step 2 – Create your signing keystore](BrowserBuildKeystore.md) of the [Browser build](BrowserBuild.md). Make sure you have read the [Option 1 vs Option 2 decision](#aaps-ci-preparation) and downloaded the preparation file.
Option 2 reuses the JKS you already created on a previous build of AAPS from a computer in Android Studio. It is suitable for users who already have a JKS and know the JKS password and alias.
For KEYSTORE_PASSWORD, KEY_ALIAS, and KEY_PASSWORD, enter your actual password and alias in GitHub – those from Android Studio, see below where you used them.
