 With this, your L1 chain should be running at port `8545`, and the `zk_chain_1` node should be running at port `3050`.
 
+## Setting up the portal
+
+The [Portal](https://github.com/matter-labs/dapp-portal) module is a web-app that allows you to:
+
+- Bridge & transfer tokens to your ZK chain.
+- View balances.
+- Add contacts for quick and easy access.
+
+Once you have at least one chain initialized, you can run the portal app locally:
+
+```bash
+zkstack portal
+```
+
+This command will start the dockerized portal app using configuration from `apps/portal.config.json` file inside your
+ecosystem directory. You can edit this file to configure the portal app if needed.
+
+You can now navigate to the portal web-app. By default, portal frontend starts on
+`http://localhost:3030`, you can configure the port in `apps.yaml` file.
+
+## Setting up a block explorer
+
+A block explorer is a web-app that lets you view and inspect transactions, blocks,
+contracts and more. A [free open source block explorer](https://github.com/matter-labs/block-explorer) is available for your ZK chain.
+
+First, each chain should be initialized:
+
+```bash
+zkstack explorer init
+```
+
+This command creates a database to store explorer data and generates a docker compose file with explorer services
+(`explorer-docker-compose.yml`).
+
+Next, for each chain you want to have an explorer, you need to start its backend services:
+
+```bash
+zkstack explorer backend --chain <chain_name>
+```
+
+This command uses previously created docker compose file to start the services (api, data fetcher, worker) required for
+the explorer.
+
+Finally, you can run the explorer app:
+
+```bash
+zkstack explorer run
+```
+
+This command will start the dockerized explorer app using configuration from `apps/explorer.config.json` file inside
+your ecosystem directory. You can edit this file to configure the app if needed.
+
+You can now navigate to the explorer web-app. By default, explorer frontend starts on
+`http://localhost:3010`, you can configure the port in `apps.yaml` file.
