+### Step 1: Choose your partner
 
 Braze Currents allows you to integrate through Data Storage using flat files or to our Behavioral Analytics and Customer Data partners using a batched JSON payloads to a designated endpoint.  
 
 Before you begin your integration, it's best to decide which integration is best for your purposes. For example, if you already utilize mParticle and Segment and would like Braze data to stream there, it would be best to use a batched JSON payload. If you would prefer to manipulate the data on your own or have a more complex system of data analysis, it might be best to use Data Storage ([Braze uses this method]({{site.baseurl}}/user_guide/data_and_analytics/braze_currents/how_braze_uses_currents/)!)

 Add a partner, sometimes called a "Currents connector," by selecting the dropdown at the top of the screen.
 
 Each partner requires a different set of configuration steps. To enable each integration, refer to our list of [available partners]({{site.baseurl}}/user_guide/data_and_analytics/braze_currents/available_partners/) and follow the instructions in their respective pages.

 Choose the events you wish to pass to that partner by checking from the available options. You can find listings of these events in our [Customer Behavior Events]({{site.baseurl}}/user_guide/data_and_analytics/braze_currents/event_glossary/customer_behavior_events/) and [Message Engagement Events]({{site.baseurl}}/user_guide/data_and_analytics/braze_currents/event_glossary/message_engagement_events/) libraries.

-## Step 5: Field transformations
+### Step 5: Set up field transformations
+
+You can use Currents field transformations to remove or hash a string field.
 
-Currents field transformations allow you to designate certain string fields in Currents for removal (replace with an empty string) or hashing (applying an SHA-256 hashing algorithm). 
+- **Remove:** Replaces the string field with `[REDACTED]`. This is helpful if your partner rejects events with missing or empty fields.
+- **Hash:** Applys an SHA-256 hashing algorithm to the string field.
 
 Selecting a field for one of these transformations will apply that transformation to all events in which that field appears. For example, selecting `email_address` for hashing will hash the `email_address` field in Email Send, Email Open, Email Bounce, and Subscription Group State Change.

+#### Testing Currents connectors
 
 Test Currents connectors are free versions of our existing connectors that can be used for testing and trying out different destinations. Test Currents have:
+
 - No limit to the number of Test Currents connectors you may build.
 - An aggregate maximum of 10,000 events per seven-day rolling period. This event total is updated hourly on the dashboard.
