 World Explorer is a GUI tool designed for visually exploring and manipulating the state of worlds.
 For the full information about it, [see the docs](http://mud.dev/world-explorer).
 
-## Installation
+## Getting started
 
-Starting with MUD 2.2, the MUD templates come with the World Explorer installed. See [Getting started](https://mud.dev/quickstart) guide for MUD for more information. 
+### Prerequisites
 
-If you have an existing MUD project you'd like to use World Explorer for, you can create a project with the new template and then use World Explorer from that project with your existing one:
+World Explorer is not intended to be used alone, and includes the following prerequisites to be set up and running:
 
-1. Create a project with the new template, which has World Explorer. Then, delete the files you no longer need.

+- Development chain (e.g. Hardhat, Foundry)

-   ```sh copy
-   pnpm create mud@main explorer --template vanilla
-   cd explorer
-   rm -rf packages/client packages/contracts
-   ```
-
-2. Edit `mprocs.yaml` to remove the definitions for `client`, `contracts`, and `anvil`.
-
-   ```yaml filename="mprocs.yaml" copy
-   procs:
-     indexer:
-       cwd: packages/contracts
-       shell: rimraf $SQLITE_FILENAME && pnpm sqlite-indexer
-       env:
-         RPC_HTTP_URL: "http://127.0.0.1:8545"
-         FOLLOW_BLOCK_TAG: "latest"
-         SQLITE_FILENAME: "indexer.db"
-     explorer:
-       cwd: packages/contracts
-       shell: pnpm explorer
-   ```
+### Installation
 
-3. Replace `packages/contracts/worlds.json` with a link to the original project's `worlds.json`.
+```sh
+pnpm add @latticexyz/explorer
+pnpm explorer
+```
 
-   ```sh copy
-   cp packages/contracts
-   rm worlds.json
-   ln -s <the original project>/packages/contracts/worlds.json .
-   cd ../..
-   ```
+Or, can be executed with a package bin directly:
 
-4. Run the new project.
+```sh
+npx @latticexyz/explorer
+```
 
-   ```sh copy
-   pnpm dev
-   ```
+### Example setup
 
-5. Browse to [World Explorer](http://localhost:13690).
