+# Run a node
+
+For detailed instructions on running a node, please refer to
+[this tutorial](https://tutorials.cosmos.network/tutorials/3-run-node/).
+Below, we provide a quick setup script to get your node up and running.
+
+:::warning
+
+Make sure to remove the `.wasmd` folder before starting this setup. The `.wasmd` folder is usually
+located in your home directory and contains all the data related to the chain. Leaving it might
+cause conflicts or errors.
+  
+:::
+
+## Setup node
+
+Run the following script to initialize and configure your node:
+
+```shell
+# Initialize the node with a moniker (name) and a specific chain ID
+wasmd init demo --chain-id=docs-chain-1
+
+# Add key pairs for alice and bob accounts
+wasmd keys add alice --keyring-backend=test
+wasmd keys add bob --keyring-backend=test
+
+# Add genesis accounts with initial balances
+wasmd genesis add-genesis-account alice "1000000000000stake" --keyring-backend=test
+wasmd genesis add-genesis-account bob "1000000000000stake" --keyring-backend=test
+
+# Create a genesis transaction for the alice account, making alice a validator
+wasmd genesis gentx alice "250000000stake" --chain-id=docs-chain-1 --amount="250000000stake" --keyring-backend=test
+
+# Collect genesis transactions to finalize the genesis file
+wasmd genesis collect-gentxs
+```
+
+## Start node
+
+To start the node, run the following command:
+
+```shell
+wasmd start
+```

+## Install Go
+
+To build and install Wasmd, Go is required. If you haven't installed Go yet, you can set it up by
+visiting the [Go download and install page](https://go.dev/doc/install).
+
+:::tip
+
+The latest version of wasmd requires `go version v1.21`.
+
+:::
+
+
+## Set up Wasmd
+
+Clone the wasmd repository
+
+```shell
+git clone https://github.com/CosmWasm/wasmd.git && cd wasmd
+```
+
+Select the most stable version
+
+```shell
+git checkout v0.52.0 # replace the v0.52.0 with the most stable version
+```
+
+Install wasmd
+
+```shell
+make install
+```
+
+You can verify the version of Wasmd you have once it is installed:
+
+```shell
+wasmd version
+```
+
+:::warning
+
+Running a node on Windows OS is not supported yet. However, you can use WSL (Windows Subsystem for
+Linux) to run a node on Windows. Alternatively, you can build a Wasmd client for Windows with:
+`make build-windows-client`.

+# Introduction
+
+Wasmd is a Cosmos-SDK sample application that integrates the [x/wasm] module, providing full support
+for Wasm smart contracts while maintaining the standard features of a Cosmos-based blockchain.
+[x/wasm] is an essential module for developers looking to build Cosmos SDK-based blockchains where
+they can deploy, execute, and manage Wasm smart contracts. In this section you will learn how to set
+up **wasmd** and integrate [x/wasm] in your blockchain.
