Contribute

We'd love your support in improving MUD! The MUD monorepo (opens in a new tab) includes all of MUD's source code, and pull requests are always welcome. To discuss new features or changes join our Discord (opens in a new tab).

You can find a list of good first issues (that don't require a lot of context on the full system) at contribute.mud.dev (opens in a new tab).

Local development setup

The following steps are only necessary if you want to contribute to MUD. To use MUD in your project, set up a new project with the MUD CLI.

  1. Ensure you have these applications installed:

    SoftwareTested with version
    curl (opens in a new tab)7.74.0
    node (opens in a new tab)18.17.0
    pnpm (opens in a new tab)8.6.11
    Foundry (opens in a new tab)0.2.0
  2. Download the source code for MUD.

    git clone https://github.com/latticexyz/mud.git
    cd mud
  3. Install and build packages.

    pnpm install
    pnpm build

Using your repository in an application

To check the changes in an application, run these commands at the application's root.

pnpm mud set-version --link <link to MUD repository>
pnpm install

While the application's pnpm dev is running, any time you pnpm build the MUD repository the application gets updated automatically.

Pull requests

MUD follows the conventional commit specification (opens in a new tab) for PR titles. Please keep the scope of your PR small (rather open multiple small PRs than one huge PR).
