+## Basic Building Blocks
+### Rust and Anchor
+Solana supports writing on-chain programs using the Rust programming language.
+Anchor is a framework for Solana's Sealevel runtime providing several convenient developer tools for writing smart contracts.
+### Typescript
+When we created this project using the Anchor framework, it generated a tests/programs.ts file. So we use typescript to write test file for contract.
