 # @polkadot/rpc-core
 
-This library provides a clean wrapper around all the methods exposed by a Polkadot network client.
-
-## Usage
-
-Installation -
-
-```
-yarn add @polkadot/rpc-core
-```
-
-Initialization -
-
-```js
-import Rpc from '@polkadot/rpc-core';
-import { WsProvider } from '@polkadot/rpc-provider/ws';
-
-const provider = new WsProvider('http://127.0.0.1:9944');
-const rpc = new Rpc(provider);
-```
-
-Retrieving the block header object for a given block header hash (a 0x-prefixed hex string with length of 64) -
-
-```js
-rpc.chain
-  .getHeader('0x1234567890')
-  .subscribe(
-    (header) => console.log(header),
-    (error) => console.error('error:', error)
-  );
-```
-
-Retrieving the best block number, parent hash, state root hash, extrinsics root hash, and digest (once-off) -
-
-```js
-rpc.chain
-  .getHead()
-  .pipe(
-    switchMap((headerHash) => {
-      return rpc.chain.getHeader(headerHash);
-    })
-  )
-  .subscribe(
-    (header) => {
-      console.log(`best #${header.number.toString()}`);
-      console.log(`parentHash: ${header.parentHash.toString()}`);
-      console.log(`stateRoot: ${header.stateRoot.toString()}`);
-      console.log(`extrinsicsRoot: ${header.extrinsicsRoot.toString()}`);
-      console.log(`digest: ${header.digest.toString()}`);
-    },
-    (error) => {
-      console.error('error:', error);
-    }
-  );
-```
-
-Retrieving best header via subscription -
-
-```js
-api.chain
-rpc
-  .subscribeNewHeads()
-  .subscribe(
-    (header) => {
-      console.log(`best #${header.number}`);
-    },
-    (error) => {
-      console.error('error subscribing:', error);
-    }
-  );
-```
+This library provides a clean wrapper around all the methods exposed by a Polkadot network client. It is only used internally to the API.
