Rename the downloaded, extracted directory to tumblr_gdpr
Put the tumblr_gdpr into your plugins.local if you have (or plugins if not). The path to init.php should be this: [TTRSS install dir]/plugins.local/tumblr_gdpr/init.php
Activate it in the UI panel configurator, or by config.php for the whole instance
Optionnally add some domains hosted by Tumblr with another URI in : "prefs/config/Tumblr GDPR"
