+summary: The Solidity Contract-Oriented Programming Language
+description: |
+  Solidity is a contract-oriented, high-level language whose syntax is similar
+  to that of JavaScript and it is designed to target the Ethereum Virtual
+  Machine (EVM).
+
+  Solidity is statically typed, supports inheritance, libraries and complex
+  user-defined types among other features.
+
+  It is possible to create contracts for voting, crowdfunding, blind auctions,
+  multi-signature wallets and more.
