+# substrate-contracts-node
+
+This repository contains Substrate's [`node-template`](https://github.com/paritytech/substrate/tree/master/bin/node-template)
+configured to include Substrate's [`pallet-contracts`](https://github.com/paritytech/substrate/tree/master/frame/contracts)
+‒ a smart contract module.
+
+This repository is tracking Substrate's `master`.
+
+## Installation
+
+Follow the [official installation steps](https://substrate.dev/docs/en/knowledgebase/getting-started/) 
+to set up all Substrate prerequisites.
+
+Afterwards you can install this node via
+
+```bash
+cargo install substrate-contracts-node --git https://github.com/paritytech/substrate-contracts-node.git --force
+```
+
+### Build Failure?
+
+Since this repository is tracking Substrate's `master` it might not yet have been adjusted to support
+the super-recent Substrate changes.
+
+Thus, if you get an error when building or installing add the cargo `--locked` flag. The installation process
+will then use the same versions as the `Cargo.lock` in this repository to ensure that the
+most recent working version of Substrate will be used.
+
+The latest confirmed working Substrate commit which will then be used is
+[852bab073407b65b5e3e461baaa0541c4e0bc3d6](https://github.com/paritytech/substrate/tree/852bab073407b65b5e3e461baaa0541c4e0bc3d6).
+
+## Usage
+
+To run a local dev node execute
+```
+substrate-contracts-node --dev --tmp
+```
+The `--tmp` implies that a new chain will be created each time the command
+is executed. If you want to persist chain state across runs leave it out.
+
+### Show only Errors and Contract Debug Output
+
+To have only errors and contract debug output show up on the console you can
+supply `-lerror,runtime::contracts=debug` when starting the node. 
+
+Important: Debug output is only printed for RPC calls or off-chain tests ‒ not for transactions!
+
+See our FAQ for more details: 
+[How do I print something to the console from the runtime?](https://paritytech.github.io/ink-docs/faq/#how-do-i-print-something-to-the-console-from-the-runtime).
