If you download an existing project that uses Foundry, it is really easy to get going.
First, get the project from somewhere. In this example, we will clone the
femplate repository from GitHub:
$ git clone https://github.com/abigger87/femplate $ cd femplate $ forge install
forge install to install the submodule dependencies that are in the project.
To build, use
$ forge build Compiling 10 files with 0.8.15 Solc 0.8.15 finished in 4.35s Compiler run successful
And to test, use
$ forge test No files changed, compilation skipped Running 1 test for test/Greeter.t.sol:GreeterTest [PASS] testSetGm() (gas: 107402) Test result: ok. 1 passed; 0 failed; finished in 4.77ms
