+		Long: `shard opens a local kava home directory's databases and removes all blocks outside a range defined by --start and --end. The range is inclusive of the end block.
+
+It works by first rolling back the latest state to the block before the end block, and then by pruning all state before the start block.
+
+Setting the end block to -1 signals to keep the latest block (no rollbacks).
+
+The application.db can be loaded at a particular height via the --force-app-version option. This is useful if the sharding process is prematurely terminated while the application.db is being sharded.
+
+The --only-app-state flag can be used to skip the pruning of the blockstore and cometbft state. This matches the functionality of the cosmos-sdk's "prune" command. Note that rolled back blocks will still affect all stores.
+
+Similarly, the --only-cometbft-state flag skips pruning app state. This can be useful if the shard command is prematurely terminated during the shard process.
+
+The shard command only flags the iavl tree nodes for deletion. Actual removal from the databases will be performed when each database is compacted.

-
-It works by first rolling back the latest state to the block before the end block, and then by pruning all state before the start block.
-
-Setting the end block to -1 signals to keep the latest block (no rollbacks).
-
-The --only-app-state flag can be used to skip the pruning of the blockstore and cometbft state. This matches the functionality of the cosmos-sdk's "prune" command. Note that rolled back blocks will still affect all stores.
