+# Docs
 
-> This is a minimal template for creating a blockchain based on Polkadot SDK.
->
-> This template is automatically updated after releases in the main [Polkadot SDK monorepo](https://github.com/paritytech/polkadot-sdk).
-
-</div>
-
-🤏 This template is a minimal (in terms of complexity and the number of components) template for building a blockchain node.
-
-🔧 Its runtime is configured of a single custom pallet as a starting point, and a handful of ready-made pallets
-such as a [Balances pallet](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/index.html).
-
-👤 The template has no consensus configured - it is best for experimenting with a single node network.
-
-## Template Structure
-
-A Polkadot SDK based project such as this one consists of:
-
-* 💿 a [Node](./node/README.md) - the binary application.
-* 🧮 the [Runtime](./runtime/README.md) - the core logic of the blockchain.
-* 🎨 the [Pallets](./pallets/README.md) - from which the runtime is constructed.
-
-## Getting Started
-
-🦀 The template is using the Rust language.
-
-👉 Check the
-[Rust installation instructions](https://www.rust-lang.org/tools/install) for your system.
-
-🛠️ Depending on your operating system and Rust version, there might be additional
-packages required to compile this template - please take note of the Rust compiler output.
-
-### Build
-
-🔨 Use the following command to build the node without launching it:
+You can generate and view the [Rust
+Docs](https://doc.rust-lang.org/cargo/commands/cargo-doc.html) for this template
+with this command:
 
 ```sh
-cargo build --release
+cargo doc -p minimal-template --open
 ```
-
-🐳 Alternatively, build the docker image:
-
-```sh
-docker build . -t polkadot-sdk-minimal-template
-```
-
-### Single-Node Development Chain
-
-👤 The following command starts a single-node development chain:
-
-```sh
-./target/release/minimal-template-node --dev
-
-# docker version:
-docker run --rm polkadot-sdk-minimal-template --dev
-```
-
-Development chains:
-
-* 🧹 Do not persist the state.
-* 💰 Are preconfigured with a genesis state that includes several prefunded development accounts.
-* 🧑‍⚖️ Development accounts are used as `sudo` accounts.
-
-### Connect with the Polkadot-JS Apps Front-End
-
-🌐 You can interact with your local node using the
-hosted version of the [Polkadot/Substrate
-Portal](https://polkadot.js.org/apps/#/explorer?rpc=ws://localhost:9944).
-
-🪐 A hosted version is also
-available on [IPFS](https://dotapps.io/).
-
-🧑‍🔧 You can also find the source code and instructions for hosting your own instance in the
-[`polkadot-js/apps`](https://github.com/polkadot-js/apps) repository.
-
-## Contributing
-
-🔄 This template is automatically updated after releases in the main [Polkadot SDK monorepo](https://github.com/paritytech/polkadot-sdk).
-
-➡️ Any pull requests should be directed to this [source](https://github.com/paritytech/polkadot-sdk/tree/master/templates/minimal).
-
-😇 Please refer to the monorepo's
-[contribution guidelines](https://github.com/paritytech/polkadot-sdk/blob/master/docs/contributor/CONTRIBUTING.md) and
-[Code of Conduct](https://github.com/paritytech/polkadot-sdk/blob/master/docs/contributor/CODE_OF_CONDUCT.md).
-
-## Getting Help
-
-🧑‍🏫 To learn about Polkadot in general, [Polkadot.network](https://polkadot.network/) website is a good starting point.
-
-🧑‍🔧 For technical introduction, [here](https://github.com/paritytech/polkadot-sdk#-documentation) are
-the Polkadot SDK documentation resources.
-
-👥 Additionally, there are [GitHub issues](https://github.com/paritytech/polkadot-sdk/issues) and
-[Substrate StackExchange](https://substrate.stackexchange.com/).

-# Runtime
-
-ℹ️ The runtime (in other words, a state transition function), refers to the core logic of the blockchain that is
-responsible for validating blocks and executing the state changes they define.
-
-💁 The runtime in this template is constructed using ready-made FRAME pallets that ship with
-[Polkadot SDK](https://github.com/paritytech/polkadot-sdk), and a [template for a custom pallet](../pallets/README.md).
-
-👉 Learn more about FRAME
-[here](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/polkadot_sdk/frame_runtime/index.html).
