This lets us verify that a gradual rollout to 10% of the users would affect the same users regardless of which SDK you're using.

 ## Client-side SDK behavior
 
 The following section details the behavior of frontend / client-side SDKs when initializing and fetching flags with respect to network connectivity.
 
-When the SDK is initialized in the application, an in memory repository is setup and synchronized against the frontent API using the configured token and context. Note that the frontend API is hosted by either the Unleash Proxy/Edge or the upstream Unleash instance directly.

 1. All feature flag evaluation is performed by the Proxy/Edge or Unleash instance. A payload of all enabled flags and their variants (if applicable) is returned as a single request. Disabled flags are not included.
 
 2. When a page inside the application requests a feature flag, the SDK will return the flag state from memory. No network connection to the frontend API is performed.
-   
 3. The SDK periodically syncs with the frontend API to retrieve the latest set of enabled flags
