 # Polkadot-API SDKs
 
-Info coming soon™
+[Polkadot-API](https://github.com/polkadot-api/polkadot-api) is designed to be modular and chain-agnostic, meaning it does not include any business-level logic. It reads the chain metadata to understand how to interact with the chain, but it is up to the developer to define its specific use and purpose.
+
+With its modular design, Polkadot-API enables the creation of additional libraries that add new layers of abstraction, significantly enhancing the developer experience when building dApps. These additional libraries are referred to as "Polkadot-API SDKs."
+
+These SDKs abstract implementation details from the pallets, elevating chain interactions to a higher level of abstraction. They handle complexities such as transaction weight calculation, associated fees, and determining the best transaction (or set of transactions) for performing specific actions.
+
+We have created several SDKs, which are implemented in this repository. The documentation can be found in the [docs site for Polkadot-API](https://papi.how/sdks/intro)
