+### Features
+#### Balance Tracking
+
+Using the `-balance-address <ADDRESS>` configuration parameter, the exporter can be used to monitor any account's
+SOL balance.
+
+#### Block Sizes
+
+If the `-monitor-block-sizes` flag is set, then the exporter will export the number of transactions (both vote and 
+non-vote transactions) in blocks produced by the monitored validators. This is a critical validator performance metric. 
+
+Cluster average block size can be inferred by dividing total network transactions by total block height.
+
+#### Income Reporting
+
+The exporter exports metrics regarding total priority fee revenue and inflation reward revenue earned by the 
+monitored validators.
+
+#### Skip Rate
+
+The exporter does not directly export skip rate, as this needs to be defined as an average over a desired timeframe. 
+However, the exporter does track the monitored validators leader slots and whether they are `valid` or `skipped`.
+
+The example prometheus setup contains [recording rules](prometheus/solana-rules.yml) for measuring average skip rate 
+for both individual validators and a cluster-level over hourly, daily and epoch intervals.
+
+#### Active/Passive Monitoring
+
+The `solana_node_is_active` metric simply reports whether the node (on which the exporter is running) has the same 
+identity-keypair as that configured with the `-active-identity` flag. The `-active-identity` flag should be used to 
+specify the primary identity when using a 
+[non-delinquent backup validator](https://pumpkins-pool.gitbook.io/pumpkins-pool).
+
+#### Light Mode
+
+Certain metrics, such as validator leader slots, income, block size and active stake, are visible on-chain through any 
+trusted node. However, other metrics such as node health and block height can only be viewed from an exporter running 
+on the node in question. Thus, on a node in which fine margins of performance are of critical interest, the exporter 
+can be set to `-light-mode`. In light mode, it will only export metrics that cannot be viewed from other nodes.
+
+This is particularly useful in setups that contain an important validator and utility RPC node - the exporter can be 
+run in light mode on the validator and in full capacity on the RPC node (configured to monitor the validator through 
+use of the `-nodekey` parameter).
+
+#### General Performance and Health
+
+In addition to the above features, the exporter provides key metrics for monitoring Solana node health and performance. 
+See [Metrics](#metrics) below for more details.
