 ## Overview
 
-0G Storage is the storage layer for the ZeroGravity data availability (DA) system. The 0G Storage layer holds three important features:
+0G Storage is a decentralized data storage system designed to address the challenges of high-throughput and low-latency data storage and retrieval, particularly for areas such as AI. 
 
-* Built-in - It is natively built into the ZeroGravity DA system for data storage and retrieval.
-* General purpose - It is designed to support atomic transactions, mutable kv stores as well as archive log systems to enable wide range of applications with various data types.
-* Incentive - Instead of being just a decentralized database, 0G Storage introduces PoRA mining algorithm to incentivize storage network participants.
+## System Architecture
 
-To dive deep into the technical details, continue reading [0G Storage Spec.](docs/)
+0G Storage consists of two main components:
 
-## Integration
+1. **Data Publishing Lane**: Ensures fast Merkle treedata root commitment and verification through 0G Chain.
+2. **Data Storage Lane**: Manages large data transfers and storage using an erasure-coding mechanism for redundancy and sharding for parallel processing.
 
-We provide a [SDK](https://github.com/0glabs/0g-js-storage-sdk) for users to easily integrate 0G Storage in their applications with the following features:
+Across the two lanes, 0G Storage supports the following features:
 
-* File Merkle Tree Class
-* Flow Contract Types
-* RPC methods support
-* File upload
-* Support browser environment
-* Tests for different environments (In Progress)
-* File download (In Progress)
+* **General Purpose Design**: Supports atomic transactions, mutable key-value stores, and archive log systems, enabling a wide range of applications with various data types.
+* **Validated Incentivization**: Utilizes the PoRA (Proof of Random Access) mining algorithm to mitigate data outsourcing issue and to ensure rewards are distributed to nodes who contribute to the storage network.
 
-## Deployment
+For in-depth technical details about 0G Storage, please read our [Intro to 0G Storage](https://docs.0g.ai/og-storage).
 
-Please refer to [Deployment](docs/run.md) page for detailed steps to compile and start a 0G Storage node.
+## Documentation
 
-## Test
+- If you want to run a node, please refer to the [Running a Node](https://docs.0g.ai/run-a-node/storage-node) guide.
+- If you want to conduct local testing, please refer to [Onebox Testing](https://github.com/0glabs/0g-storage-node/blob/main/docs/onebox-test.md) guide.
+- If you want build a project using 0G storage, please refer to the [0G Storage SDK](https://docs.0g.ai/build-with-0g/storage-sdk) guide.
 
-Please refer to the [One Box Test](docs/onebox-test.md) page for local testing purpose.
+## Support and Additional Resources
+We want to do everything we can to help you be successful while working on your contribution and projects. Here you'll find various resources and communities that may help you complete a project or contribute to 0G.
