Initial setup

Create a gradle.properties file and add Unsplash API client ID constant:

UNSPLASH_CLIENT_ID="..."
APPCENTER_SECRET_KEY="..."

Create a keystore.properties file and add the following keys:

storePassword=...
keyPassword=...
keyAlias=...

Provide correct values for your keystore.

Finally create or move an existing keystore file (has to be named keystor.jks) to the projects root directory.

After all this is done you can run gradlew installRelease.
