# Description

@itsacoyote @MexicanAce 
- Updated the explorer and portal usage to use the new zkstack cli
commands.
- Updated zkstack prover guide to use the new zkstack cli commands.
- Moved "validium in zk stack" higher in dropdown instead of being last.
- Updated some inconsistent titles to match format of others.

Possibly a bit OCD of me to do this, but was playing with zkstack today
and they stayed in my mind bothering me hahahah 😉

-You can run all components together locally and connect to your ZK chain.

-
-### Running block explorer locally
-
-#### Install block explorer
-
-Clone & install the block explorer repository in any folder:
+First, each chain should be initialized:
 
 ```bash
-git clone https://github.com/matter-labs/block-explorer.git
-cd block-explorer
-npm install
+zkstack explorer init
 ```
 
-#### Setting up env variables
+This command creates a database to store explorer data and generates a docker compose file with explorer services
+(`explorer-docker-compose.yml`).
 
-Next you need to set up all the necessary environment and configuration files with your ZK chain settings.
-You can use the available npm script to set them up:
+Next, for each chain you want to have an explorer, you need to start its backend services:
 
 ```bash
-npm run hyperchain:configure
+zkstack explorer backend --chain <chain_name>
 ```
 
-#### Run block explorer
+This command uses previously created docker compose file to start the services (api, data fetcher, worker) required for
+the explorer.
 
-Afterwards you can run the block explorer:
-
-```bash
-# if you are running block explorer for the first time
-npm run db:create
-```
+Finally, you can run the explorer app:
 
 ```bash
-npm run dev
+zkstack explorer run
 ```
 
-#### Verify block explorer is up and running
+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.
 
-By default, you can access the front-end `App` at <http://localhost:3010> in your browser. The  `API` is
- available by default at <http://localhost:3020>, `Worker` at <http://localhost:3001> and `Data Fetcher` at <http://localhost:3040>.
+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.
