+### Fund your sBTC wallet address
+In order to deploy the sBTC contract you must first fund your STX address listed above in the `config.json` file.
+
+Download a wallet client:
+
+  - [Leather Wallet Browser Extension](https://leather.io/install-extension)
+  - [Leather Wallet Desktop Client](https://github.com/leather-wallet/desktop/releases)
+
+If you wish to use the desktop client, you *MUST* download the testnet version of the executable.
+
+You can use any one of the wallet mnemonic phrases in the `romeo/asset-contract/settings/Devnet.toml` file for the client.
+
+Now send 100 STX to your STX address you generated with the `sbtc-cli` above.
