### 🕸️ Run a local network
You will need a compatible release of [Polkadot](https://github.com/paritytech/polkadot) to run a local network. You may also want to use [Zombienet](https://github.com/paritytech/zombienet/releases) (available for Linux and MacOS), for spinning up a full fledged relay chain - parachain environment. You can find more information about running a local test network [HERE](./docs/zombienet.md)

You can download executables of the Zombienet CLI from [paritytech/zombienet/releases](https://github.com/paritytech/zombienet/releases)


- Download the Zombienet CLI according to your operating system.
- Download the latest Zombienet CLI according to your operating system.

💡 Tip: If you want the executable to be available system-wide then make sure you place it in one of your `$PATH` directories.
```sh
wget https://github.com/paritytech/zombienet/releases/download/v1.3.30/zombienet-macos
wget https://github.com/paritytech/zombienet/releases/download/v1.3.71/zombienet-macos
chmod +x zombienet-macos
cp zombienet-macos /usr/local/bin
```
Then invoke it anywhere like :
```sh
# Mac Os
zombienet-macos --help
```
Otherwise you can just place it in your working directory.

```sh
./zombienet-macos --help
```sh
# Linux
zombienet-linux-x64 --help
```
You should see some similar output:

## Setting up Zombienet config:

You may use a reference implementation from the folder `zombienet-config` or make your own. We provide a simple configuration for you called [zombienet-config.toml](../zombienet-config.toml) which spins up two validators for the relay chain, and one collator for your parachain to get you quickly upto speed.

⚠️ Take note: the path of the polkadot executable used there is `../bin/polkadot` which means you need to have a folder called `bin` outside the repository directory which contains your compiled polkadot binary which must be named as `polkadot`. Also please take care to compile the correct version of `polkadot` when testing out on your machine. You can do so by cloning `polkadot` and then checking out the appropriate branch that corresponds to the substrate/cumulus version used to build the template.
⚠️ Note: The path of the polkadot executable used there is `./bin/polkadot` which means you need to have a folder called `bin` inside the repository directory which contains your compiled polkadot binary named as `polkadot`. In addition to that since version 1.1.0, you will also need to place the `polkadot-execute-worker` and the `polkadot-prepare-worker` binaries to be inside `bin`. As a user you don't need to interact with these but these are required to start up the main relay chain `polkadot` software. You can find all three [here](https://github.com/paritytech/polkadot-sdk/releases/tag/polkadot-v1.1.0)
