+# Quick Start Guide for zkSync Node
+
+## Prerequisites
+
+- **Installations Required:**
+  - [Docker](https://docs.docker.com/get-docker/)
+  - [Docker Compose](https://docs.docker.com/compose/install/)
+
+## Setup Instructions
+
+1. Clone the zkSync Era repository and navigate to the external node guide:
+
+   ```
+   git clone https://github.com/matter-labs/zksync-era.git
+   cd zksync-era/docs/guides/external-node
+   ```
+
+## Running a zkSync Node Locally
+
+### Starting the Node
+
+- **For a Mainnet instance:**
+
+  ```sh
+  cd docker-compose-examples
+  docker compose --file mainnet-external-node-docker-compose.yml up
+  ```
+
+- **For a Testnet instance:**
+
+  ```sh
+  cd docker-compose-examples
+  docker compose --file testnet-external-node-docker-compose.yml up
+  ```
+
+### Resetting the Node State
+
+- **For a Mainnet instance:**
+
+  ```sh
+  cd docker-compose-examples
+  docker compose --file mainnet-external-node-docker-compose.yml down --volumes
+  ```
+
+- **For a Testnet instance:**
+
+  ```sh
+  cd docker-compose-examples
+  docker compose --file testnet-external-node-docker-compose.yml down --volumes
+  ```
+
+### Monitoring Node Status
+
+Access the local Grafana dashboard to see the node status after recovery:
+[Local Grafana Dashboard](http://localhost:3000/d/0/external-node).
+
+### API Access
+
+- **HTTP JSON-RPC API:** Port `3060`
+- **WebSocket API:** Port `3061`
+
+### Important Notes
+
+- **Initial Recovery:** The node will recover from a snapshot on its first run, which may take up to 10 hours. During this period, the API server will not serve any requests.
+- **Historical Data:** For access to historical transaction data, consider recovery from DB dumps. Refer to the Advanced Setup section for more details.
+- **DB Dump:** For nodes that operate from a DB dump, which allows starting a zkSync node with a full historical transactions history, refer to the documentation on running from DB dumps at [03_running.md](https://github.com/matter-labs/zksync-era/blob/main/docs/guides/external-node/03_running.md).
+
+## System Requirements
+
+The following are minimal requirements:
+
+- **CPU:** A relatively modern CPU is recommended.
+- **RAM:** 32 GB
+- **Storage:**
+  - **Testnet Nodes:** 30 GB
+  - **Mainnet Nodes:** 300 GB, with the state growing about 1TB per month.
+- **Network:** 100 Mbps connection (1 Gbps+ recommended)
+
+## Advanced Setup
+
+For additional configurations like monitoring, backups, recovery from DB dump or snapshot, and custom PostgreSQL settings, please refer to the [ansible-en-role repository](https://github.com/matter-labs/ansible-en-role).
