 ## Command line options
 Command options can only by placed after command.
 
+* **apply-load**: Applies Soroban transactions by repeatedly generating transactions and closing
+them directly through the LedgerManager. The parameters specified below configure the network limits, and
+they're all required - **--ledger-max-instructions N**, **--ledger-max-read-entries N**, **--ledger-max-write-entries N**, **--ledger-max-read-byte N**, **--ledger-max-write-bytes N**, **--ledger-max-tx-size N**, **--ledger-max-tx-count N**. This command will generate enough transactions to fill up a synthetic transaction queue (it's just a list of transactions with the same limits as the real queue), and then create a transaction set off of that to
+apply.
+
+* At the moment, the Soroban transactions are generated using some of the same config parameters as the **generateload** command. Specifically,
+    `ARTIFICIALLY_GENERATE_LOAD_FOR_TESTING=true`,
+    `LOADGEN_NUM_DATA_ENTRIES_FOR_TESTING`,
+    `LOADGEN_NUM_DATA_ENTRIES_DISTRIBUTION_FOR_TESTING`,
+    `LOADGEN_IO_KILOBYTES_FOR_TESTING`,
+    `LOADGEN_IO_KILOBYTES_DISTRIBUTION_FOR_TESTING`,
+    `LOADGEN_TX_SIZE_BYTES_FOR_TESTING`,
+    `LOADGEN_TX_SIZE_BYTES_DISTRIBUTION_FOR_TESTING`,
+    `LOADGEN_INSTRUCTIONS_FOR_TESTING`, and
+    `LOADGEN_INSTRUCTIONS_DISTRIBUTION_FOR_TESTING`.
+
 * **catchup <DESTINATION-LEDGER/LEDGER-COUNT>**: Perform catchup from history
   archives without connecting to network. For new instances (with empty history
   tables - only ledger 1 present in the database) it will respect LEDGER-COUNT
