 # astria-oracle-contracts
 
 Repository of contracts used for Astria's native oracle.
+
+### deploy 
+
+Copy the example .env: `cp local.env.example .env`
+
+Put your private key in `.env` and `source .env`.
+
+To deploy `AstriaOracle.sol`:
+
+```sh
+forge script script/AstriaOracle.s.sol:AstriaOracleScript \
+   --rpc-url $RPC_URL --broadcast --sig "deploy()" -vvvv
+```
+
+### query contract
+
+The script has an example function which calls `getPrice()` for `ETH/USD`. You can update the test for different currency pair strings to get their price.
+
+```sh
+forge script script/AstriaOracle.s.sol:AstriaOracleScript    --rpc-url $RPC_URL --broadcast --sig "getPrice()" -vvvv
+```
