+
+1. Make a new account in Metamask (or whichever method you prefer). Copy paste the address into `genesis.json`'s `alloc` field. This account will be allocated 300 ETH at startup.
+
+2. Replace the etherbase in the following with your account (it doesn't really matter though, since mining doesn't require signing). Then, run:
+```bash
+make geth
+./build/bin/geth --datadir ~/.astriageth/ init genesis.json
+./build/bin/geth --datadir ~/.astriageth/ --http --http.port=8545 --ws --ws.port=8545 --networkid=1337 --http.corsdomain='*' --ws.origins='*' --mine --miner.threads 1 --miner.etherbase=0xDB8c0F738639Da247bC67251548a186b2107bf4d
+```
+
+4. Open up Metamask and go to the Localhost 8545 network. You should see your account has 300 ETH. You can now transfer this to other accounts.
