To start a new project with Foundry, use forge init:
$ forge init hello_foundry
This creates a new directory hello_foundry from the default template. This also initializes a new git repository.
Use forge build to compile the project
forge build

This will create a folder out with compiled information like the abi and bytecode
Anvil is a local testnet node shipped with Foundry. You can use it for testing your contracts from frontends or for interacting over RPC.
To use Anvil, simply type anvil. You should see a list of accounts and private keys available for use, as well as the address and port that the node is listening on.
$ anvil

Use forge create to deploy a smart contract to the specified blockchain
forge create SimpleStorage --rpc-url <rpc url>
Example of deploying to a local Anvil network with a dummy private key
forge create SimpleStorage --rpc-url 127.0.0.1:8545 --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
We can create an .env file to store our parameters, and run source .env
export PRIVATE_KEY=0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80
export RPC_URL=127.0.0.1:8545
The we can run the command like this
forge create SimpleStorage --rpc-url $RPC_URL --broadcast --private-key $PRIVATE_KEY
To deploy to Sepolia, we simply need to run the same script command with a Sepolia private key and rpc-url with a Sepolia address and node
forge script script/DeploySimpleStorage.s.sol --rpc-url $SEPOLIA_RPC_URL --broadcast --private-key $SEPOLIA_PRIVATE_KEY
