+## Benchmarking
+
+DataHaven uses runtime benchmarking to generate accurate weight calculations for all pallets. The benchmarking process is automated using `frame-omni-bencher`.
+
+### Requirements
+
+- `frame-omni-bencher` - Install with: `cargo install frame-omni-bencher --profile=production`
+
+### Running Benchmarks
+
+Execute the benchmarking script from the project root:
+
+```bash
+# Benchmark all pallets for testnet runtime (default)
+./scripts/run-benchmarks.sh
+
+# Benchmark specific runtime
+./scripts/run-benchmarks.sh mainnet
+
+# Custom steps and repetitions
+./scripts/run-benchmarks.sh testnet 100 50
+```
+
+The script will:
+1. Automatically discover all available pallets
+2. Build the runtime WASM with `runtime-benchmarks` feature
+3. Generate weight files in `runtime/{runtime}/src/weights/`
+4. Provide a summary of successful and failed benchmarks
+
+### Script Parameters
+
+- `runtime`: Runtime to benchmark (testnet, stagenet, mainnet). Default: testnet
+- `steps`: Number of steps for benchmarking. Default: 50  
+- `repeat`: Number of repetitions. Default: 20
+
 ## Zombienet testing
 
 First, install [zombienet](https://github.com/paritytech/zombienet).
