-The script `node index.js` uses the configured goerli bridge to bridge 1 STT on Goerli into 1 SNT on Optimism-Goerli.
+- `$YOUR_MNEMONIC` is the mnemonic that contains the account from which you want to deploy. The deploy script will use

+- `$YOUR_RPC_URL` is the RPC endpoint of the node you're connecting to.
 
-To everything work, .env needs to be created out of .env.example.
+You can omit the `--broadcast` option to simulate the deployment before actually performing it.

 # Differences from regular MiniMeToken
 
+The MiniMeToken used in this repository is a fork of [the original](https://github.com/Giveth/minime). To learn about
+the differences between the fork and the upstream repository, head over to its

 1. There are 2 functions to mint/burn, one is mint() & generateTokens(), and other is burn() & destroyTokens(). One come
    from MiniMeToken inheritance, and other comes from IOptimismMintableERC20 inheritance. See more on point 2.
 2. MiniMeToken controller (SNTPlaceHolder) is also deployed on Optimism, and it _could_ be replaced by another
