-This guide shows you how to profile your Aztec transactions to identify bottlenecks and optimize gas usage.
+This guide shows you how to profile Aztec transactions to understand gate counts and identify optimization opportunities.
 
 ## Prerequisites
 
-- `aztec` command installed ([see installation](../../../aztec-cli/local-network-reference.md))
-- `aztec-wallet` installed
-- Aztec contract deployed and ready to test
-- Basic understanding of proving and gate counts
+- Aztec sandbox running ([installation guide](../../../aztec-cli/local-network-reference.md))
+- A deployed contract to profile
 
 ## Profile with aztec-wallet
 
-### Step 1: Import test accounts
+Use the `profile` command instead of `send` to get detailed gate counts:
 
 ```bash
+# Import test accounts
 aztec-wallet import-test-accounts
-```
-
-### Step 2: Deploy your contract
 
-```bash
+# Deploy your contract
 aztec-wallet deploy MyContractArtifact \
   --from accounts:test0 \
-  --args <constructor_args> \
+  --args [CONSTRUCTOR_ARGS] \
   -a mycontract
-```
-
-### Step 3: Set up initial state
-
-```bash
-aztec-wallet send setup_state \
-  -ca mycontract \
-  --args <setup_args> \
-  -f test0
-```
-
-### Step 4: Profile a transaction
 
-Instead of `send`, use `profile` with the same parameters:
-
-```bash
-aztec-wallet profile private_function \
+# Profile a function call
+aztec-wallet profile my_function \
   -ca mycontract \
-  --args <function_args> \
+  --args [FUNCTION_ARGS] \
   -f accounts:test0
 ```
 
-### Step 5: Analyze the output
+### Reading the output
 
-```bash
-Gate count per circuit:
-   SchnorrAccount:entrypoint                          Gates: 21,724     Acc: 21,724
-   private_kernel_init                                Gates: 45,351     Acc: 67,075
-   MyContract:private_function                        Gates: 31,559     Acc: 98,634
-   private_kernel_inner                               Gates: 78,452     Acc: 177,086
-   private_kernel_reset                               Gates: 91,444     Acc: 268,530
-   private_kernel_tail                                Gates: 31,201     Acc: 299,731
-
-Total gates: 299,731
-```
+The profile command outputs a per-circuit breakdown:
 
-The output shows:
+```text
+Per circuit breakdown:
 
-- Gate count per circuit component
-- Accumulated gate count
-- Total gates for the entire transaction

-Batch operations to reduce kernel circuit overhead.
-:::
+## Profile with aztec.js
 
-```rust
-// ❌ Multiple kernel invocations
-for i in 0..3 {
-    transfer_single(amounts[i], recipients[i]);
-}
+```typescript
+const result = await contract.methods.my_function(args).profile({
+  from: walletAddress,
+  profileMode: "full",
+  skipProofGeneration: true,
+});
 
-// ✅ Single kernel invocation
-for i in 0..3 {
-    let note = Note::new(amounts[i], recipients[i]);
-    storage.notes.at(recipients[i]).insert(note);
+// Access gate counts from execution steps
+for (const step of result.executionSteps) {
+  console.log(`${step.functionName}: ${step.gateCount} gates`);
 }
-```
-
-:::tip Storage Optimization
-Group storage reads to reduce overhead.
-:::
 
-```rust
-// Read once, use multiple times
-let values = [storage.v1.get(), storage.v2.get(), storage.v3.get()];
-for v in values {
-    assert(v > 0);
-}
+// Access timing information
+console.log("Total time:", result.stats.timings.total, "ms");
 ```
 
-### Minimize note operations
-
-:::tip Note Aggregation
-Combine multiple small notes into fewer larger ones to reduce proving overhead.
-:::
+### Profile modes
 
-```rust
-// ❌ Many small notes = high overhead
-for value in values {
-    storage.notes.insert(Note::new(value, owner));
-}
+- `gates`: Gate counts per circuit
+- `execution-steps`: Detailed execution trace with bytecode and witnesses
+- `full`: Complete profiling information (gates + execution steps)
 
-// ✅ Single aggregated note = lower overhead
-let total = values.reduce(|a, b| a + b);
-storage.notes.insert(Note::new(total, owner));
-```
+Set `skipProofGeneration: true` for faster iteration when you only need gate counts.
 
-## Profile different scenarios
+## Generate flamegraphs with noir-profiler
 
-### Profile with different inputs
+For deeper analysis of individual contract functions, use the Noir profiler to generate interactive flamegraphs. The profiler is installed automatically with Nargo (starting noirup v0.1.4).
 
 ```bash
-# Small values
-aztec-wallet profile function -ca mycontract --args 10 -f test0
-
-# Large values
-aztec-wallet profile function -ca mycontract --args 1000000 -f test0
-```
-
-### Profile execution modes
-
-```javascript
-// Profile gates only
-await contract.methods.function().profile({ profileMode: 'gates' });
-
-// Profile execution steps
-await contract.methods.function().profile({ profileMode: 'execution-steps' });
-
-// Full profile
-await contract.methods.function().profile({ profileMode: 'full' });
-```
+# Compile your contract first
+aztec compile
 
-### Skip proof generation for faster iteration
+# Generate a gates flamegraph (requires bb backend)
+noir-profiler gates \
+  --artifact-path ./target/my_contract-MyContract.json \
+  --backend-path bb \
+  --output ./target
 
-```javascript
-await contract.methods.function().profile({
-  profileMode: 'gates',
-  skipProofGeneration: true  // Faster but less accurate
-});
+# Generate an ACIR opcodes flamegraph
+noir-profiler opcodes \
+  --artifact-path ./target/my_contract-MyContract.json \
+  --output ./target
 ```
 
-## Interpret profiling results
-
-### Gate count guidelines
-
-- **< 50,000 gates**: Excellent performance
-- **50,000 - 200,000 gates**: Acceptable for most use cases
-- **200,000 - 500,000 gates**: May cause delays, consider optimizing
-- **> 500,000 gates**: Requires optimization for production
-
-### Common optimization targets
-
-1. **private_kernel_inner** - Reduce nested function calls
-2. **private_kernel_reset** - Minimize note nullifications
-3. **Contract functions** - Optimize computation logic
-4. **private_kernel_tail** - Reduce public function calls
-
-## Best practices
+Open the generated `.svg` file in a browser for an interactive view where:
 
-### Development workflow
+- **Width** represents gate count or opcode count
+- **Height** represents call stack depth
+- **Wide sections** indicate optimization targets
 
-1. **Profile early** - Establish baseline metrics
-2. **Profile often** - Check impact of changes
-3. **Profile realistically** - Use production-like data
-4. **Document findings** - Track optimization progress
+For detailed usage, see the [Noir profiler documentation](https://noir-lang.org/docs/tooling/profiler).
 
-### Optimization priorities
+## Gate count guidelines
 
-1. **User-facing functions** - Optimize most-used features first
-2. **Critical paths** - Focus on transaction bottlenecks
-3. **Batch operations** - Combine related operations
-4. **Cache calculations** - Store reusable results
