 # Substrate Node Template
 
-A new FRAME-based Substrate node, ready for hacking :rocket:

-## Local Development
+## Getting Started
 
-Follow these steps to prepare a local Substrate development environment :hammer_and_wrench:
+Follow these steps to get started with the Node Template :hammer_and_wrench:
 
-### Simple Setup
+### Rust Setup
 
-Install all the required dependencies with a single command (be patient, this can take up to 30
-minutes).
+First, complete the [basic Rust setup instructions](./doc/rust-setup.md).
 
-```bash
-curl https://getsubstrate.io -sSf | bash -s -- --fast
-```
+### Run
 
-### Manual Setup
+Use Rust's native `cargo` command to build and launch the template node:
 
-Find manual setup instructions at the
-[Substrate Developer Hub](https://substrate.dev/docs/en/knowledgebase/getting-started/#manual-installation).
+```sh
+cargo run --release -- --dev --tmp
+```
 
 ### Build
 
-Once the development environment is set up, build the node template. This command will 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:
+The `cargo run` command will perform an initial build. Use the following command to build the node
+without launching it:
 
-```bash
+```sh
 cargo build --release
 ```
 
-## Run
-
-### Single Node Development Chain
+### Embedded Docs
 
-Purge any existing dev chain state:
+Once the project has been built, the following command can be used to explore all parameters and
+subcommands:
 
-```bash
-./target/release/node-template purge-chain --dev
+```sh
+./target/release/node-template -h
 ```
 
-Start a dev chain:
+## Run
 
-```bash
-./target/release/node-template --dev
-```
+The provided `cargo run` command will launch a temporary node and its state will be discarded after
+you terminate the process. After the project has been built, there are other ways to launch the
+node.
+
+### Single-Node Development Chain
 
-Or, start a dev chain with detailed logging:
+This command will start the single-node development chain with persistent state:
 
 ```bash
-RUST_LOG=debug RUST_BACKTRACE=1 ./target/release/node-template -lruntime=debug --dev
+./target/release/node-template --dev
 ```
 
-### Multi-Node Local Testnet
-
-To see the multi-node consensus algorithm in action, run a local testnet with two validator nodes,
-Alice and Bob, that have been [configured](./node/src/chain_spec.rs) as the initial
-authorities of the `local` testnet chain and endowed with testnet units.
-
-Note: this will require two terminal sessions (one for each node).
-
-Start Alice's node first. The command below uses the default TCP port (30333) and specifies
-`/tmp/alice` as the chain database location. Alice's node ID will be
-`12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp` (legacy representation:
-`QmRpheLN4JWdAnY7HGJfWFNbfkQCb6tFf4vvA6hgjMZKrR`); this is determined by the `node-key`.
+Purge the development chain's state:
 
 ```bash
-cargo run -- \
-  --base-path /tmp/alice \
-  --chain=local \
-  --alice \
-  --node-key 0000000000000000000000000000000000000000000000000000000000000001 \
-  --telemetry-url 'ws://telemetry.polkadot.io:1024 0' \
-  --validator
+./target/release/node-template purge-chain --dev
 ```
 
-In another terminal, use the following command to start Bob's node on a different TCP port (30334)
-and with a chain database location of `/tmp/bob`. The `--bootnodes` option will connect his node to
-Alice's on TCP port 30333:
+Start the development chain with detailed logging:
 
 ```bash
-cargo run -- \
-  --base-path /tmp/bob \
-  --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp \
-  --chain=local \
-  --bob \
-  --port 30334 \
-  --ws-port 9945 \
-  --telemetry-url 'ws://telemetry.polkadot.io:1024 0' \
-  --validator
+RUST_BACKTRACE=1 ./target/release/node-template -ldebug --dev
 ```
 
-Execute `cargo run -- --help` to learn more about the template node's CLI options.

-## Generate a Custom Node Template
+### Run in Docker
 
-Generate a Substrate node template based on a particular commit by running the following commands:
+First, install [Docker](https://docs.docker.com/get-docker/) and
+[Docker Compose](https://docs.docker.com/compose/install/).
+
+Then run the following command to start a single node development chain.
 
 ```bash
-# Clone from the main Substrate repo
-git clone https://github.com/paritytech/substrate.git
-cd substrate
+./scripts/docker_run.sh
+```
 
-# Switch to the branch or commit to base the template on
-git checkout <branch/tag/sha1>
+This command will firstly compile your code, and then start a local development network. You can
+also replace the default command (`cargo build --release && ./target/release/node-template --dev --ws-external`)
+by appending your own. A few useful ones are as follow.
 
-# Run the helper script to generate a node template. This script compiles Substrate, so it will take
-# a while to complete. It expects a single parameter: the location for the script's output expressed
-# as a relative path.
-.maintain/node-template-release.sh ../node-template.tar.gz
-```
+```bash
+# Run Substrate node without re-compiling
+./scripts/docker_run.sh ./target/release/node-template --dev --ws-external
+
+# Purge the local dev chain
+./scripts/docker_run.sh ./target/release/node-template purge-chain --dev
 
-Custom node templates are not supported. Please use a recently tagged version of the
-[Substrate Developer Node Template](https://github.com/substrate-developer-hub/substrate-node-template)
-in order to receive support.
+# Check whether the code is compilable

+title: Installation
+---
+
+This page will guide you through the steps needed to prepare a computer for development with the
+Substrate Node Template. Since Substrate is built with
+[the Rust programming language](https://www.rust-lang.org/), the first thing you will need to do is
+prepare the computer for Rust development - these steps will vary based on the computer's operating
+system. Once Rust is configured, you will use its toolchains to interact with Rust projects; the
+commands for Rust's toolchains will be the same for all supported, Unix-based operating systems.
+
+## Unix-Based Operating Systems
+
+Substrate development is easiest on Unix-based operating systems like macOS or Linux. The examples
+in the Substrate [Tutorials](https://substrate.dev/tutorials) and [Recipes](https://substrate.dev/recipes/)
+use Unix-style terminals to demonstrate how to interact with Substrate from the command line.
+
+### macOS
+
+Open the Terminal application and execute the following commands:
+
+```bash
+# Install Homebrew if necessary https://brew.sh/
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
+
+# Make sure Homebrew is up-to-date, install openssl and cmake
+brew update
+brew install openssl cmake
+```
+
+### Ubuntu/Debian
+
+Use a terminal shell to execute the following commands:
+
+```bash
+sudo apt update
+# May prompt for location information
+sudo apt install -y cmake pkg-config libssl-dev git build-essential clang libclang-dev curl
+```
+
+### Arch Linux
+
+Run these commands from a terminal:
+
+```bash
+pacman -Syu --needed --noconfirm cmake gcc openssl-1.0 pkgconf git clang
+export OPENSSL_LIB_DIR="/usr/lib/openssl-1.0"
+export OPENSSL_INCLUDE_DIR="/usr/include/openssl-1.0"
+```
+
+### Fedora/RHEL/CentOS
+
+Use a terminal to run the following commands:
+
+```bash
+# Update
+sudo dnf update
+# Install packages
+sudo dnf install cmake pkgconfig rocksdb rocksdb-devel llvm git libcurl libcurl-devel curl-devel clang
+```
+
+## Rust Developer Environment
+
+This project uses [`rustup`](https://rustup.rs/) to help manage the Rust toolchain. First install
+and configure `rustup`:
+
+```bash
+# Install
+curl https://sh.rustup.rs -sSf | sh
+# Configure
+source ~/.cargo/env
+```
+
+Finally, configure the Rust toolchain:
+
+```bash
+rustup default stable
+rustup update nightly
+rustup update stable
+rustup target add wasm32-unknown-unknown --toolchain nightly
+```
