Because we have `default_platform` defined, we can skip the `--platform` or `--part` argument.
Because we have `default_platform` defined, we can skip the `--part` argument.
We can also skip the `--target` argument because we have a `default_target` defined for the
chosen platform. This will default to the `bitstream` target of `xc7a50t` platform:

A basic example of using F4PGA:
$ f4pga build --platform arty_35 -t bitstream
$ f4pga build --flow flow.json --part XC7A35TCSG324-1 -t bitstream
This will make F4PGA attempt to create a bitstream for arty_35 platform.
``flow.json`` is a flow configuration file, which should be created for a project that uses F4PGA.
