+### Profiling gas usage
+
+This *experimental* feature lets you [profile gas usage](https://github.com/aptos-labs/aptos-core/tree/main/aptos-move/aptos-gas-profiling) in the Aptos virtual machine locally rather than [simulating transactions](../../concepts/gas-txn-fee.md#estimating-the-gas-units-via-simulation) at the [fullnode](https://fullnode.devnet.aptoslabs.com/v1/spec#/operations/simulate_transaction). You may also use it to visualize gas usage in the form of a flame graph.
+
+Run the gas profiler by appending the `--profile-gas` option to the Aptos CLI `move publish`, `move run` or `move run-script` command, for example:
+```bash
+aptos move publish --profile-gas
+```
+
+And receive output resembling:
+```bash

+Note these limitations of the experimental gas profiling feature:
+
+  * It may produce results that are different from the simulation.
+  * The graphs may contain errors, and the numbers may not add up to the total gas cost as shown in the transaction output.

 ## Estimating the gas units via simulation
 
-The gas used for a transaction can be estimated by simulating the transaction. When simulating the transaction, the simulation results represent the **exact** amount that is needed at the **exact** state of the blockchain at the time of simulation. These gas units used may change based on the state of the chain.  For this reason, any amount coming out of the simulation is only an estimate, and when setting the max gas amount, it should include an appropriate amount of headroom based upon your comfort-level and historical behaviors. Setting the max gas amount too low will result in the transaction aborting and the account being charged for whatever gas was consumed.
+The gas used for a transaction can be estimated by simulating the transaction on chain as described here or locally via the [gas profiling](../cli-tools/aptos-cli-tool/use-aptos-cli.md#profiling-gas-use) feature of the Aptos CLI.

 Transactions can be simulated with the [`SimulateTransaction`](https://fullnode.devnet.aptoslabs.com/v1/spec#/operations/simulate_transaction) API. This API will run the exact transaction that you plan to run.
