+# World Explorer
+
+World Explorer is a GUI tool designed for visually exploring and manipulating the state of worlds.
+
+## Getting started
+
+##### 1. **Install the package**
+
+```sh
+pnpm add @latticexyz/explorer
+```
+
+##### 2. **Start a local development chain**
+
+Ensure you have a local development chain running.
+
+##### 3. **Run the World Explorer**
+
+```sh
+npx @latticexyz/explorer --worldAddress <YOUR_WORLD_ADDRESS>
+```
+
+Alternatively, if you have a worlds configuration file:
+
+```sh
+npx @latticexyz/explorer --worldsConfigPath <PATH_TO_WORLDS_CONFIG>
+```
+
+Note: You can use `@latticexyz/store-indexer` for indexing your world's data.
+
+## CLI arguments
+
+The World Explorer accepts the following CLI arguments:
+
+| Argument          | Description                                                                      | Default value |
+| ----------------- | -------------------------------------------------------------------------------- | ------------- |
+| `worldAddress`    | The address of the world to explore                                              | None          |
+| `worldsFile`      | Path to a worlds configuration file (used to resolve world address)              | None          |
+| `indexerDatabase` | Path to your SQLite indexer database                                             | "indexer.db"  |
+| `chainId`         | The chain ID of the network                                                      | 31337         |
+| `port`            | The port on which to run the World Explorer                                      | 13690         |
+| `env`             | The environment to run the World Explorer in (e.g., "development", "production") | "production"  |
+
+## Example setup
+
+An example setup is provided in the `examples/local-explorer` directory, demonstrating a full setup for using the World Explorer in a local development environment:
+
+##### 1. **Setup**
+
+```sh
+cd examples/local-explorer && pnpm install
+```
+
+##### 2. **Run**
+
+```sh
+pnpm dev
+```
+
+This command starts all necessary processes, including a local chain, indexer, and the explorer.
+
+## Contributing
+
+To contribute to or modify the World Explorer, the easiest way is to run the example setup in `development` mode:
+
+##### 1. **Setup**
+
+Navigate to the `examples/local-explorer` directory and locate the `mprocs.yaml` file.
+
+##### 2. **Configure**
+
+In `mprocs.yaml`, ensure the `explorer` command is set up correctly. For example:
+
+```yaml
+explorer:
+  shell: pnpm explorer --worldsConfigPath packages/contracts/worlds.json --env development
+```
+
+##### 3. **Run**
+
+```sh
+pnpm dev
+```
+
+Files can now be edited in the `packages/explorer` directory, and changes will be reflected in the running World Explorer instance.
