+## v0.1.0-dev.14
+
+This is a development pre-release.
+
+Supported `polkadot-sdk` rev:`c29e72a8628835e34deb6aa7db9a78a2e4eabcee`
+
+### Added
+- The `revive-runner` helper utility binary which helps to run contracts locally without a blockchain node. 
+- Allow configuration of the EVM heap memory size and stack size via CLI flags and JSON input settings.
+
+### Changed
+- The default PVM stack memory size was increased from 16kb to 32kb.
+
 ### Fixed
 - Constructors avoid storing zero sized immutable data on exit.

+# revive-runner
+
+The revive runner is a helper utility aiding in contract debugging.
+
+Given a PVM contract blob, it will upload, deploy and call that contract using a local, stand-alone un-blockchained pallet revive (which is our execution layer).
+
+This is somewhat similar to the geth `evm` utility binary.
+
+## Installation
+
+The `revive-runner` does not depend on the compiler itself, hence installing this utility does not depend on LLVM, so no LLVM build is required.
+
+Inside the root `revive` repository directory, execute:
+
+```bash
+make install-revive-runner
+```
+
+Which will install the `revive-runner` using `cargo`. 
+
+## Usage
+
+Set the `RUST_LOG` environment varibale to the `trace` level to see the full PolkaVM execution trace. For example:
+
+```bash
+RUST_LOG=trace revive-runner -f mycontract.pvm -c a9059cbb000000000000000000000000f24ff3a9cf04c71dbc94d0b566f7a27b94566cac0000000000000000000000000000000000000000000000000000000000000000
