Working on an Existing Project

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

We run forge install to install the submodule dependencies that are in the project.

To build, use forge build:

$ 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:

$ 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
