 # Simple ROFL Oracle Contract
 
-See the ROFL tutorial for some examples on how to use this project.
+For the ROFL Oracle smart contract delpoyment you will need the following
+information:
+
+- the ROFL app ID (rofl1...)
+- the deployer's private key
+- the network you're deploying to (sapphire-testnet, sapphire-localnet,
+  sapphire)
+
+First install dependencies and compile the smart contract:
+
+```shell
+npm install
+npx hardhat compile
+```
+
+Then, prepare your hex-encoded private key for paying the deployment gas fee
+and store it as an environment variable:
+
+```shell
+export PRIVATE_KEY=0x...
+```
+
+Finally, deploy the contract, provide the ROFL App ID and the network:
+
+```shell
+npx hardhat deploy rofl1... --network sapphire-localnet
+```
+
+Once your Oracle ROFL is running, it will submit the observations to the smart
+contract deployed above. You can fetch the data stored on-chain by running:
+
+```shell
+npx hardhat oracle-query 0xbdEd0D2bf404bdcBa897a74E6657f1f12e5C6fb6 --network sapphire-localnet
+```
