 One of the build targets of the Solidity repository is ``solc``, the solidity commandline compiler.
 Using ``solc --help`` provides you with an explanation of all options. The compiler can produce various outputs, ranging from simple binaries and assembly over an abstract syntax tree (parse tree) to estimations of gas usage.
-If you only want to compile a single file, you run it as ``solc --bin sourceFile.sol`` and it will print the binary. If you want to get some of the more advanced output variants of ``solc``, it is probably better to tell it to output everything to separate files using ``solc -o outputDirectory --bin --ast --asm sourceFile.sol``.

 Before you deploy your contract, activate the optimizer when compiling using ``solc --optimize --bin sourceFile.sol``.
 By default, the optimizer will optimize the contract assuming it is called 200 times across its lifetime
