+# Create an ICS chain with Spawn
+
+## Requirements
+
+- [`go 1.22+`](https://go.dev/doc/install)
+- [`Docker`](https://docs.docker.com/get-docker/)
+
+[MacOS + Ubuntu Setup](https://github.com/rollchains/spawn/blob/release/v0.50/docs/versioned_docs/version-v0.50.x/01-setup/01-system-setup.md)
+
+## Getting Started
+
+**Note:** This tutorial focuses on using the Spawn CLI to create an ICS consumer chain. For more complete documentation on Spawn, see the [Spawn documentation](https://rollchains.github.io/spawn/v0.50/).
+
+In this tutorial, we'll create and interact with a new Interchain security enabled blockchain called "consumer", with the token denomination "uconsu".
+
+1. Clone this repo and install
+
+```shell
+git clone https://github.com/rollchains/spawn.git
+cd spawn
+git checkout v0.50.4
+make install
+```
+
+2. Create your chain using the `spawn` command and customize it to your needs!
+
+```shell
+GITHUB_USERNAME=<your-github-username>
+
+spawn new consumer \
+--consensus=interchain-security \
+--bech32=consu `# the prefix for addresses` \
+--denom=uconsu `# the coin denomination to create` \
+--bin=consumerd `# the name of the binary` \
+--disabled=tokenfactory,globalfee,ibc-packetforward,ibc-ratelimit,cosmwasm,wasm-light-client,optimistic-execution,ignite-cli `# disable features. [tokenfactory,globalfee,ibc-packetforward,ibc-ratelimit,cosmwasm,wasm-light-client,ignite-cli]` \
+--org=${GITHUB_USERNAME} `# the github username or organization to use for the module imports, optional`
+```
+
+> _NOTE:_ `spawn` creates a ready to use repository complete with `git` and GitHub CI. It can be quickly pushed to a new repository getting you and your team up and running quickly.
+
+3. Spin up a local testnet for your chain
+
+```shell
+cd consumer
+
+# Starts 2 networks for the IBC testnet at http://127.0.0.1:8080.
+# - Builds the docker image of your chain
+# - Launches a testnet with IBC automatically connected and relayed
+#
+# Note: you can run a single node, non IBC testnet, with `make sh-testnet`.
+make testnet
+```
+
+4. Open a new terminal window and send a transaction on your new chain
+
+```shell
+# list the keys that have been provisioned with funds in genesis
+consumerd keys list
+
+# send a transaction from one account to another
+consumerd tx bank send acc0 $(consumerd keys show acc1 -a) 1337uconsu --chain-id=localchain-1
+
+# enter "y" to confirm the transaction
+# then query your balances tfor proof the transaction executed successfully
+consumerd q bank balances $(consumerd keys show acc1 -a)
+```
+
+5. (optional) Send an IBC transaction
+
+```shell
+# submit a cross chain transfer from acc0 to the other address
+consumerd tx ibc-transfer transfer transfer channel-0 cosmos1hj5fveer5cjtn4wd6wstzugjfdxzl0xpxvjjvr 7uconsu --from=acc0 --chain-id=localchain-1 --yes
+
+# Query the other side to confirm it went through
+sleep 10
+
+# Interact with the other chain without having to install the cosmos binary
+# - Endpoints found at: GET http://127.0.0.1:8080/info
+local-ic interact localcosmos-1 query 'bank balances cosmos1hj5fveer5cjtn4wd6wstzugjfdxzl0xpxvjjvr' --api-endpoint=http://127.0.0.1:8080
+```
+
+6. Push your new chain to a github repository
+
+```shell
+# Create a new repository on GitHub from the gh cli
+gh repo create ics-consumer --source=. --remote=origin --push
+```
+
+> You can also push it the old fashioned way with https://github.com/new and `git push origin main`.
+
+In this tutorial, we configured a new custom chain, launched a testnet for it, tested a simple token transfer, and confirmed it was successful.
+This tutorial demonstrates just how easy it is to create a brand new custom Cosmos-SDK blockchain from scratch, saving developers time.
+
+## Modify your chain
+
+New module code is usually added in the `x/` directory of your repository.
+Check out the [Cosmos SDK documentation](https://docs.cosmos.network/v0.50/build/building-modules/intro) for more information on how to add modules to your chain.
+
+Once you're ready you can preview your chain using the section below.
+
+## List your chain
+
+You can [list your chain on Forge](https://forge.cosmos.network/list-your-chain), even if it's not finished, in the **pre-launch** stage.
