@@ -44,6 +44,7 @@ This section describes the required dependencies that this framework requires to
 - ETH-RPC - All communication with Kitchensink is done through the ETH RPC.
 - Solc - This is actually a transitive dependency, while this tool doesn't require solc as it downloads the versions that it requires, resolc requires that Solc is installed and available in the path.
 - Resolc - This is required to compile the contracts to PolkaVM bytecode.
+- Kurtosis - The Kurtosis CLI tool is required for the production Ethereum mainnet-like node configuration with Geth as the execution layer and lighthouse as the consensus layer. Kurtosis also requires docker to be installed since it runs everything inside of docker containers.
 
 All of the above need to be installed and available in the path in order for the tool to work.

+# ML Test Runner
+
+A test runner for executing Revive differential tests file-by-file with cargo-test-style output.
+
+This is similar to the `retester` binary but designed for ML-based test execution with a focus on:
+- Running tests file-by-file (rather than in bulk)
+- Caching passed tests to skip them in future runs
+- Providing cargo-test-style output for easy integration with ML pipelines
+- Single platform testing (rather than differential testing)
+
+## Features
+
+- **File-by-file execution**: Run tests on individual `.sol` files, corpus files (`.json`), or recursively walk directories
+- **Cached results**: Skip tests that have already passed using `--cached-passed`
+- **Fail fast**: Stop on first failure with `--bail`
+- **Cargo-like output**: Familiar test output format with colored pass/fail indicators
+- **Platform support**: Test against `geth` or `kitchensink` platforms
+
+## Usage
+
+```bash
+# Run a single .sol file (compile-only mode, default)
+./ml-test-runner path/to/test.sol --platform geth
+
+# Run all tests in a corpus file
+./ml-test-runner path/to/corpus.json --platform kitchensink
+
+# Walk a directory recursively for .sol files
+./ml-test-runner path/to/tests/ --platform geth
+
+# Use cached results and bail on first failure
+./ml-test-runner path/to/tests/ --cached-passed ./cache.txt --bail
+
+# Start the platform and execute tests (full mode)
+./ml-test-runner path/to/tests/ --platform geth --start-platform
+
+# Enable verbose logging (info, debug, or trace level)
+RUST_LOG=info ./ml-test-runner path/to/tests/
+RUST_LOG=debug ./ml-test-runner path/to/tests/ --start-platform
+RUST_LOG=trace ./ml-test-runner path/to/tests/ --start-platform
+```
+
+## Arguments
+
+- `<PATH>` - Path to test file (`.sol`), corpus file (`.json`), or folder of `.sol` files
+- `--cached-passed <FILE>` - File to track tests that have already passed
+- `--bail` - Stop after the first file failure
+- `--platform <PLATFORM>` - Platform to test against (`geth`, `kitchensink`, or `zombienet`, default: `geth`)
+- `--start-platform` - Start the platform and execute tests (default: `false`, compile-only mode)
+
+## Output Format
+
+The runner produces cargo-test-style output:
+
+```
+test path/to/test1.sol ... ok
+test path/to/test2.sol ... FAILED
+test path/to/test3.sol ... cached
+
+failures:
+
+---- path/to/test2.sol ----
+Error: ...
+
+test result: FAILED. 1 passed; 1 failed; 1 cached; finished in 2.34s
+```
+
+## Building
+
+```bash
+cargo build --release -p ml-test-runner
+```
+
+The binary will be available at `target/release/ml-test-runner`.
