+## Foundry
+
+**Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.**
+
+Foundry consists of:
+
+-   **Forge**: Ethereum testing framework (like Truffle, Hardhat and DappTools).
+-   **Cast**: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
+-   **Anvil**: Local Ethereum node, akin to Ganache, Hardhat Network.
+-   **Chisel**: Fast, utilitarian, and verbose solidity REPL.
+
+## Documentation
+
+https://book.getfoundry.sh/
+
+## Usage
+
+### Build
+
+```shell
+$ forge build
+```
+
+### Test
+
+
+```shell
+$ forge test -vv
+```
+
+To learn more about logs and traces, check out the documentation [here](https://book.getfoundry.sh/forge/tests?highlight=-vv#logs-and-traces).
+
+To view all of the supported logging methods, check out the documentation [here](https://book.getfoundry.sh/reference/ds-test#logging).
+
+### Gas Snapshots
+
+```shell
+$ forge snapshot
+```
+
+### Anvil
+You can start the local EVM test network at any time:
+
+```shell
+$ anvil
+```
+
+### Deploy
+
+```shell
+export PRIVATE_KEY=<your-private-key>
+
+$ forge script script/CallService.s.sol:CallServiceScript --rpc-url <your_rpc_url> --private-key <your_private_key>
+
+For Example: (deploying the contract on localnet) 
+$ forge script script/CallService.s.sol:CallServiceScript --fork-url http://localhost:8545 \
+--private-key $PRIVATE_KEY --broadcast
+
+```
+
+
+### Cast
+Set the CONTRACT_ADDRESS variable in your terminal:
+
+```sh
+export CONTRACT_ADDRESS=<your-contract-address>
+```
+
+Call initialize on the contract
+
+```sh
+cast send $CONTRACT_ADDRESS "initialize(string)" "ENTER Chain NID HERE" --private-key $PRIVATE_KEY
+```
+
+We can then use cast to interact with it.
+
+For read operations, we can use cast call: For Example:
+
+```sh
+cast call $CONTRACT_ADDRESS "admin()(address)"
+```
+
+For transactions, we can use cast send, passing in a private key and any arguments:
+
+```sh
+cast send $CONTRACT_ADDRESS "setAdmin(address)" 0x9965507D1a55bcC2695C58ba16FB37d819B0A4dc --private-key $PRIVATE_KEY
+```
+
+To test that the greeting has been updated, run the `call` command again:
+
+```sh
+cast call $CONTRACT_ADDRESS "admin()(address)"
+```
+
+
+## Installing packages
+
+You can install packages using the `forge install` command.
+
+To try this out, let's install OpenZeppelin Contracts, then we'll use them to create an ERC721 token:
+
+> You may need to add and commit any changes to your code to `git` in order to run the install script.
+
+```sh
+forge install OpenZeppelin/openzeppelin-contracts
+```
+
+Next, create a file named `remappings.txt` in the root of the project and add the following configuration:
+
+```
+@openzeppelin/=lib/openzeppelin-contracts/
+```
+
+This will allow us to easily import with the following syntax:
+
+```solidity
+import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
+```
+
+You can view all of the automatically inferred remappings for the project by running the following command:
+
+```sh
+forge remappings
+```
+
+
+### Test coverage
+
+You can check for test coverage by running the `coverage` command:
+
+```sh
+forge coverage
+```
+
+To debug in more details what has not been covered, use the `debug` report:
+
+```sh
+forge coverage --report debug
+```
+
+
+
+### Help
+
+```shell
+$ forge --help
+$ anvil --help
+$ cast --help
+```
