+This guide will walk you through the steps to create a local FireFly development environment running against the preview node.
+
+## Previous steps: Install the FireFly CLI
+
+If you haven't set up the FireFly CLI already, please go back to the Getting Started guide and read the section on how to [Install the FireFly CLI](../../gettingstarted/firefly_cli.md).

+
+## Create the stack
+
+A Cardano stack can be run in two different ways; with a firefly
+
+### Option 1: Use a local Cardano node
+
+> **NOTE**: The cardano-node communicates over a Unix socket, so this will not work on Windows.
+
+Start a local cardano node. The fastest way to do this is to [use mithril](https://mithril.network/doc/manual/getting-started/bootstrap-cardano-node/) to bootstrap the node.
+
+For an example of how to bootstrap and run the cardano node in docker, see [the firefly-cardano repo](https://github.com/hyperledger/firefly-cardano/blob/1be3b08d301d6d6eeb5b79e40cf3dbf66181c3de/infra/docker-compose.node.yaml#L4).
+
+The cardano-node exposes a Unix socket named `node.socket`. Pass that to firefly-cli. The example below uses `firefly-cli` to
+ - Create a new Cardano-based stack named `dev` with 1 member.
+ - Disable `multiparty` mode.
+ - Connect to the local Cardano node, which is running in the [preview network](https://preview.cexplorer.io/).
+
+```sh
+ff init cardano dev 1 \
+    --multiparty false \
+    --network preview \
+    --socket /path/to/ipc/node.socket
+```
+
+### Option 2: Use Blockfrost
+
+The Cardano connector can also use the [paid Blockfrost API](https://blockfrost.io/) in place of a local Cardano node.
+
+The example below uses firefly-cli to
+ - Create a new Cardano-based stack named `dev` with 1 member.
+ - Disable `multiparty` mode.
+ - Use the given block
+
+```sh
+ff init cardano dev 1 \
+    --multiparty false \
+    --network preview \
+    --blockfrost-key previewXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+```
+
+## Start the stack
+
+Now you should be able to start your stack by running:
+
+```sh
+ff start dev
+```
+
+After some time it should print out the following:
+
+```
+Web UI for member '0': http://127.0.0.1:5000/ui
+Sandbox UI for member '0': http://127.0.0.1:5109
+
+
+To see logs for your stack run:
+
+ff logs dev
+```
+
+## Get some ADA
+
+Now that you have a stack, you need some seed funds to get started. Your stack was created with a wallet already (these are free to create in Cardano). To get the address, you can run
+```sh
+ff accounts list dev
+```
+
+The response will look like
+```json
+[
+  {
+    "address": "addr_test1...",
+    "privateKey": "..."
+  }
+]
+```
+
+If you're developing against a testnet such as preview, you can receive funds from the [testnet faucet](https://docs.cardano.org/cardano-testnets/tools/faucet). Pass the `address` from that response to the faucet.
