So please do not hesitate and open an [issue in GitHub](https://github.com/ethereum/solidity/issues) if you encounter anything strange. +Solidity is a statically-typed curly-braces programming language designed for developing smart contracts +that run on the Ethereum Virtual Machine. Smart contracts are programs that are executed inside a peer-to-peer +network where nobody has special authority over the execution and thus they allow to implement tokens of value, +ownership, voting and other kinds of logics. -## Building -See the [Solidity documentation](https://solidity.readthedocs.io/en/latest/installing-solidity.html#building-from-source) for build instructions. +## Build and Install -## How to Contribute -Please see our [contribution guidelines](https://solidity.readthedocs.io/en/latest/contributing.html) in the Solidity documentation. +Instructions about how to build and install the Solidity compiler can be found in the [Solidity documentation](https://solidity.readthedocs.io/en/latest/installing-solidity.html#building-from-source) + + +## Example + +A "Hello World" program in Solidity is of even less use than in other languages, but still: + +``` +contract HelloWorld { + function f() pure returns (string memory) { + return "Hello, World!"; + } +} +``` + +To get started with Solidity, you can use [Remix](https://remix.ethereum.org/), which is an +browser-based IDE.
