# Solana Program Use the Solana Program Crate to write on-chain programs in Rust. If writing client-side applications, use the [Solana SDK Crate](https://crates.io/crates/solana-sdk) instead. More information about Solana is available in the [Solana documentation](https://solana.com/docs). [Solana Program Library](https://github.com/solana-labs/solana-program-fork-cleon-00-library) provides examples of how to use this crate. Still have questions?
