+# Runtime
+
+ℹ️ The runtime (in other words, a state transition function), refers to the core logic of the teyrchain that is
+responsible for validating blocks and executing the state changes they define.
+
+💁 The runtime in this template is constructed using ready-made FRAME pallets that ship with
+[Pezkuwi SDK](https://github.com/pezkuwichain/pezkuwi-sdk), and a [template for a custom pallet](../pallets/README.md).
+
+👉 Learn more about FRAME
+[here](https://docs.pezkuwichain.io/sdk/master/polkadot_sdk_docs/polkadot_sdk/frame_runtime/index.html).
