### Build

Once you have prepared your local development environment, you can build the node template. Use this
command to build the [Wasm](https://substrate.dev/docs/en/knowledgebase/advanced/executor#wasm-execution)
and [native](https://substrate.dev/docs/en/knowledgebase/advanced/executor#native-execution) code:

```bash
cargo build --release

The Substrate Playground is an online development environment that allows you to take advantage of a pre-configured container with pre-compiled build artifacts 🤸‍♀️

Run

Single Node Development Chain

Purge any existing developer chain state:

./target/release/node-template purge-chain --dev

Start a development chain with:

./target/release/node-template --dev

Detailed logs may be shown by running the node with the following environment variables set: RUST_LOG=debug RUST_BACKTRACE=1 cargo run -- --dev.
