+## Error Events
 
+- **SampleRate** - Configures the sample rate for error events, in the range of 0.0 to 1.0. The default is 1.0, which means that 100% of error events will be sent. If set to 0.1, only 10% of error events will be sent. Events are picked randomly.
+
+## Tracing
 
 - **tracesSampleRate** - A number between 0 and 1, controlling the percentage chance a given transaction will be sent to Sentry. (0 represents 0% while 1 represents 100%.) Applies equally to all transactions created in the app. Either this or `tracesSampler` must be defined to enable tracing.
 
 - **tracesSampler** - A function responsible for determining the percentage chance a given transaction will be sent to Sentry. It will automatically be passed information about the transaction and the context in which it's being created, and must return a number between 0 (0% chance of being sent) and 1 (100% chance of being sent). Can also be used for filtering transactions, by returning 0 for those that are unwanted. Either this or `tracesSampleRate` must be defined to enable tracing.
 
+## Session Replay
+
 - **replaysSessionSampleRate** - The sample rate for replays that begin recording immediately and last the entirety of the user's session. 1.0 collects all replays, and 0 collects none.
 
 - **replaysOnErrorSampleRate** - The sample rate for replays that are recorded when an error happens. This type of replay will record up to a minute of events prior to the error and continue recording until the session ends. 1.0 captures all sessions with an error, and 0 captures none.
 
-- **SampleRate** - Configures the sample rate for error events, in the range of 0.0 to 1.0. The default is 1.0, which means that 100% of error events will be sent. If set to 0.1, only 10% of error events will be sent. Events are picked randomly.
