-## Experimental: Use Flag Identifier with Percentage Rollout Hash
+## Percentage Rollout Experimental Features
 
-### Elixir
+### Hash Flag Identifier
+
+This option uses murmur3 hash on the flag identifier, and then appends the hash onto the flag identifier. The full 
+bitstring then runs through murmur3 hash again.
+
+#### Elixir
 
-To enable this, set `hash_flag_and_target_ids` to true.
+Activation: To activate this feature, set `hash_flag_and_target_ids` to true.
 
-If `hash_flag_and_target_ids` is not explicitly set, or set to false, the SDK will use the original hashing method.
+Default Behavior: If `hash_flag_and_target_ids` is not explicitly set, or set to false, the SDK will only hash the target identifier.

+### Multiply hash by a prime number
+
+This option will multiply the hash by the number you provide. We recommend a prime number, like 17.
+
+### Elixir
+
+Activation: To activate this feature, set the value of `prime_multiplication_for_rollout` to your required number
+
+Combination: This feature can be used alongside `hash_flag_and_target_ids` 
+
+Default Behavior: If `prime_multiplication_for_rollout` is not explicitly set, or set to false, the SDK will proceed without multiplying the hash.

 ## Run multiple instances of the SDK
 
 The SDK by default starts up a single instance called `default` which is configured with your project API key.
