-zkSync Era Block Explorer
+<h1 align="center">zkSync Era Block Explorer</h1>
+
+<p align="center">Online blockchain browser for viewing and analyzing <a href="https://zksync.io">zkSync Era</a> blockchain.</p>
+
+## 📌 Overview
+This repository is a monorepo consisting of 3 packages:
+- [Worker](./packages/worker) - an indexer service for [zkSync Era](https://zksync.io) blockchain data. The purpose of the service is to read the data from the blockchain in real time, transform it and fill in it's database with the data in a way that makes it easy to be queried by the [API](./packegs/api) service.
+- [API](./packages/api) - a service providing Web API for retrieving structured [zkSync Era](https://zksync.io) blockchain data collected by [Worker](./packages/worker). It connects to the Worker's database to be able to query the collected data.
+- [App](./packages/app) - a front-end app providing an easy-to-use interface for users to view and inspect transactions, blocks, contracts and more. It makes requests to the [API](./packages/api) to get the data and presents it in a way that's easy to read and understand.
+
+## 🏛 Architecture
+The following diagram illustrates how are the block explorer components connected:
+
+```mermaid
+flowchart
+  subgraph blockchain[Blockchain]
+    Blockchain[zkSync Era JSON-RPC API]
+  end
+
+  subgraph explorer[Block explorer]
+    Database[("Block explorer DB<br/>(PostgreSQL)")]
+    Worker(Worker service)
+    API(API service)
+    App(App)
+
+    Worker-.Save processed data.->Database
+    API-.Query data.->Database
+    App-."Request data (HTTP)".->API
+    App-."Request data (HTTP)".->Blockchain
+  end
+
+  Worker-."Request data (HTTP)".->Blockchain
+```
+
+[Worker](./packages/worker) service is responsible for getting data from blockchain using [zkSync Era JSON-RPC API](https://era.zksync.io/docs/api/api.html), processing it and saving into the database. [API](./packages/api) service is connected to the same database where it gets the data from to handle API requests. It performs only read requests to the database. The front-end [App](./packages/app) makes HTTP calls to the Block Explorer [API](./packages/api) to get blockchain data and to the [zkSync Era JSON-RPC API](https://era.zksync.io/docs/api/api.html) for reading contracts, performing transactions etc.
+
+## 🚀 Features
+
+- ✅ View transactions, blocks, transfers and logs.
+- ✅ Inspect accounts, contracts, tokens and balances.
+- ✅ Verify smart contracts.
+- ✅ Interact with smart contracts.
+- ✅ Standalone HTTP API.
+- ✅ Local node support.
+
+## 📋 Prerequisites
+
+- Ensure you have `node >= 18.0.0` and `npm >= 9.0.0` installed.
+
+## 🛠 Installation
+
+```bash
+$ npm install
+```
+
+## ⚙️ Setting up env variables
+
+Make sure you have set up all the necessary env variables. Follow [Setting up env variables for Worker](./packages/worker#setting-up-env-variables) and [Setting up env variables for API](./packages/api#setting-up-env-variables) for instructions.
+
+## 👨‍💻 Running locally
+
+Before running the solution, make sure you have a database server up and running and you have created a database.
+
+To run all the components (`Worker`, `API` and front-end `App`) in `development` mode run the following command from the root directory.
+```bash
+$ npm run dev
+```
+
+For `production` mode run:
+```bash
+$ npm run build
+$ npm run start
+```
+To verify front-end `App` is running open http://localhost:3010 in your browser. `API` should be available at http://localhost:3000. `Worker` - http://localhost:3001.
+
+Each component can also be started individually. Follow individual packages `README` for details.
+
+## 🕵️‍♂️ Testing
+Run unit tests for all packages:
+```bash
+$ npm run test
+```
+Run e2e tests for all packages:
+```bash
+$ npm run test:e2e
+```
+Run tests for a specific package:
+```bash
+$ npm run test -w {package}
+```
+For more details on testing please check individual packages `README`.
