First, we need to install Ubuntu on WSL (Windows Subsystem for Linux).

1. Open PowerShell as Administrator (Search for PowerShell, right-click, and select Run as Administrator).

2. Run this command to install WSL with Ubuntu:

   wsl --install Ubuntu

3. Restart your computer when asked.

4. After restarting, open Ubuntu from the Start Menu.

Success Check: You should see a terminal asking you to create a username and password.

Now, we will install Podman, which is an alternative to Docker.

1. In your Ubuntu terminal, update your system:

   sudo apt update && sudo apt upgrade -y

2. Install Podman:

   sudo apt install podman -y

3. Verify Podman is installed:

   podman --version

   If you see a version number, Podman is installed correctly!

Since most guides use Docker, we can make Podman respond to Docker commands.
Run this in Ubuntu:

sudo ln -s /usr/bin/podman /usr/bin/docker

Now you can use Docker commands, but they will actually run with Podman.

Now, let's download the container image we need.

1. Open Ubuntu and run:

   podman pull ghcr.io/unionlabs/union/mpc-client:v1.2

   This downloads the container image from GitHub Container Registry (GHCR).

2. Check if the image was downloaded:

   You should see something like:

   REPOSITORY                               TAG   IMAGE ID   CREATED   SIZE  
   ghcr.io/unionlabs/union/mpc-client      v1.2  abc123xyz  2 days ago  500MB

Now that we have the container image, let's run it.

1. Create a folder for the ceremony data:

   mkdir -p ~/ceremony

2. Run the container:

   podman run -v ~/ceremony:/ceremony -w /ceremony -p 4919:4919 --rm -it ghcr.io/unionlabs/union/mpc-client:v1.2

   This starts the container and makes it ready to use.

To check if the container is running, open another Ubuntu terminal and type:

If it’s running, you will see the container ID and details.
