-# IOST - A Scalable & Developer Friendly Blockchain 
+# IOST - A High-Performance, Developer-Friendly Blockchain
 
-IOST is a smart contract platform focusing on performance and developer friendliness. 
+IOST is a smart contract platform designed with a strong emphasis on performance and developer experience. It provides a robust infrastructure for building complex blockchain applications with ease and efficiency.
 
 # Features
 
-1. The V8 JavaScript engine is integrated inside the blockchain, so you can use JavaScript to write smart contracts!
-2. The blockchain is highly scalable with thousands of TPS. Meanwhile it still has a more decentralized consensus than DPoS.
-3. 0.5 second block, 0.5 minute finality.
-4. Free transactions. You can stake coins to get gas.
+1. **V8 JavaScript Engine**: The V8 JavaScript engine is integrated directly into the blockchain, enabling developers to write smart contracts using JavaScript. This brings about a world of benefits as JavaScript is a universally known language, making the development process easier and quicker. Furthermore, the V8 engine, being Google Chrome's open-source JavaScript engine, is known for its speed, which translates into extremely efficient smart contract execution.
 
-# Development
+2. **High Scalability**: IOST blockchain delivers high throughput with thousands of transactions per second (TPS), making it suitable for large-scale applications. While maintaining this high scalability, it also employs a more decentralized consensus mechanism than DPoS (Delegated Proof of Stake), ensuring a balance between performance and decentralization.
 
-### Environments
+3. **Fast Block Times and Finality**: With a 0.5-second block time and 0.5-minute finality, developers can create responsive, real-time applications. This rapid finality ensures transactions are confirmed quickly, in less than a minute. This is a highly desirable feature for developers as it improves user experience by providing swift, secure transaction confirmations.
 
-OS: Ubuntu 22.04 or later  
-Go: 1.20 or later
+4. **Free Transactions**: IOST offers free transactions. Users can stake coins to acquire gas, eliminating the need for transaction fees and making the platform more user-friendly.
 
-IOST node uses CGO V8 javascript engine, so only x64 is supported now.
+# Development
 
-### Deployment
+### Environment Requirements
 
-build local binary: `make build`  
-start a local devnet: `make debug`     
-build docker: `make image`  
+- OS: Ubuntu 22.04 or later  
+- Go: 1.20 or later
 
+Please note that the IOST node utilizes the CGO V8 JavaScript engine and currently only supports the x64 architecture.
