 # bt-decode
 A python wrapper around the rust scale-codec crate for fast scale-decoding of Bittensor data structures.
+
+## Usage
+
+### DelegateInfo
+#### get_delegates
+```python
+import bittensor
+from bt_decode import DelegateInfo
+
+# Setup subtensor connection
+subtensor = bittensor.subtensor()
+# Grab result from RuntimeAPI
+hex_bytes_result = sub.query_runtime_api(
+    runtime_api="DelegateInfoRuntimeApi",
+    method="get_delegates",
+    params=[ ]
+)
+# Decode scale-encoded DelegateInfo
+delegates_info: List[DelegateInfo] = DelegateInfo.decode_vec(
+    bytes.fromhex(
+        hex_bytes_result
+))
+```
+#### get_delegated
+```python
+import bittensor
+from bt_decode import DelegateInfo
+
+validator_key = bittensor.Keypair(ss58_address="5E9fVY1jexCNVMjd2rdBsAxeamFGEMfzHcyTn2fHgdHeYc5p")
+
+# Setup subtensor connection
+subtensor = bittensor.subtensor()
+# Grab result from RuntimeAPI
+hex_bytes_result = sub.query_runtime_api(
+    runtime_api="DelegateInfoRuntimeApi",
+    method="get_delegated",
+    params=[list( validator_key.public_key )]
+)
+# Decode scale-encoded (DelegateInfo, take)
+delegated_info: List[Tuple[DelegateInfo, int]] = DelegateInfo.decode_delegated(
+    bytes.fromhex(
+        hex_bytes_result
+))
+```
+
+### StakeInfo
+#### get_stake_info_for_coldkey
+```python
+import bittensor
+from bt_decode import StakeInfo
+
+validator_key = bittensor.Keypair(ss58_address="5HBtpwxuGNL1gwzwomwR7sjwUt8WXYSuWcLYN6f9KpTZkP4k")
+
+# Setup subtensor connection
+subtensor = bittensor.subtensor()
+encoded_coldkey = list( validator_key.public_key )
+# Grab result from RuntimeAPI
+hex_bytes_result = sub.query_runtime_api(
+    runtime_api="StakeInfoRuntimeApi",
+    method="get_stake_info_for_coldkey",
+    params=[encoded_coldkey]
+)
+# Decode scale-encoded StakeInfo
+stake_info: List[StakeInfo] = StakeInfo.decode_vec(
+    bytes.fromhex(
+        hex_bytes_result
+))
+```
+
+#### get_stake_info_for_coldkeys
+```python
+import bittensor
+from bt_decode import StakeInfo
+
+validator_key_0 = bittensor.Keypair(ss58_address="5GcCZ2BPXBjgG88tXJCEtkbdg2hNrPbL4EFfbiVRvBZdSQDC")
+validator_key_1 = bittensor.Keypair(ss58_address="5HBtpwxuGNL1gwzwomwR7sjwUt8WXYSuWcLYN6f9KpTZkP4k")
+
+encoded_coldkeys = [
+    list( validator_key_0.public_key ),
+    list( validator_key_1.public_key )
+]
+
+# Setup subtensor connection
+subtensor = bittensor.subtensor()
+# Grab result from RuntimeAPI
+hex_bytes_result = sub.query_runtime_api(
+    runtime_api="StakeInfoRuntimeApi",
+    method="get_stake_info_for_coldkeys",
+    params=[encoded_coldkeys]
+)
+# Decode scale-encoded (AccountId, StakeInfo)
+stake_info: List[Tuple[bytes, List["StakeInfo"]]] = StakeInfo.decode_vec_tuple_vec(
+    bytes.fromhex(
+        hex_bytes_result
+))
+```
