## Entrypoints ## Entrypoints
Each LIGO smart contract is essentially a single function, that has the following *(pseudo)* type signature: Each LIGO smart contract is essentially a single main function, referring to the following types:

This means that every smart contract needs at least one entrypoint function, here's an example: Each main function receives two arguments:
- `parameter` - this is the parameter received in the invocation operation
- `storage` - this is the current (real) on-chain storage value
Storage can only be modified by running the smart contract entrypoint, which is responsible for returning a pair holding a list of operations, and a new storage.
Here is an example of a smart contract main function:

Each entrypoint function receives two arguments: A contract entrypoints are the constructors of the parameter type (variant) and you must use pattern matching (`case`, `match`, `switch`) on the parameter in order to associate each entrypoint to its corresponding handler.
- `parameter` - this is the parameter received in the invocation operation
- `storage` - this is the current (real) on-chain storage value
Storage can only be modified by running the smart contract entrypoint, which is responsible for returning a list of operations, and a new storage at the end of it's execution. To access the 'entrypoints' of a contract, we define a main function whose parameter is a variant type with constructors for each entrypoint. This allows us to satisfy the requirement that LIGO contracts always begin execution from the same function. The main function simply takes this variant, pattern matches it to determine which entrypoint to dispatch the call to, then returns the result of executing that entrypoint with the projected arguments.
> The LIGO variant's are compiled to a Michelson annotated tree of union type.
