 ## Geocoding
 
-IP geocoding is performed in a background job so it doesn’t slow down web requests. You can disable it entirely with:
+AuthTrail uses [Geocoder](https://github.com/alexreisner/geocoder) for geocoding. We recommend configuring [local geocoding](#local-geocoding) so IP addresses are not sent to a 3rd party service. If you do use a 3rd party service and adhere to GDPR, be sure to add it to your subprocessor list.
 
+To enable geocoding, update `config/initializers/authtrail.rb`:
+
 ```ruby
-AuthTrail.geocode = false
+AuthTrail.geocode = true
 ```
 
-Set job queue for geocoding
+Geocoding is performed in a background job so it doesn’t slow down web requests. Set the job queue with:
 
 ```ruby
 AuthTrail.job_queue = :low_priority

-To avoid calls to a remote API, download the [GeoLite2 City database](https://dev.maxmind.com/geoip/geoip2/geolite2/) and configure Geocoder to use it.
+For privacy and performance, we recommend geocoding locally. Add this line to your application’s Gemfile:

   ip_lookup: :geoip2,

+
+For country-level geocoding, install the `geoip-database` package. It’s preinstalled on Heroku. For Ubuntu, use:
+
+```sh
+sudo apt-get install geoip-database
+```
+
