 The CENNZNet JavaScript SDK for browsers, RN and Node.js.
 
-## Quick Start
-
-You must use **yarn** with @cennznet/api and set the following **resolutions** in your package.json, otherwise your install may break due to breaking changes in downstream package versions.
-
 ## Install
 
 ```
 $> npm i --save @cennznet/api
 ```
 
-At the moment a breaking change in the recent versions of polkadot has prevented us from updating with the recent versions. 
-That's why in package.json there should be a resolution set so we can make sure the right version of polkadot packages are fetched. Therefore you need to have the following lines in your package.json:
-```json
-"dependencies": {
-  "@cennznet/api": "^1.2.1"
-},
-"resolutions": {
-  "@polkadot/types": "1.2.1",
-  "@polkadot/metadata": "1.2.1",

-  "@polkadot/rpc-core": "1.2.1",
-  "@polkadot/rpc-provider": "1.2.1",
-  "@polkadot/jsonrpc": "1.2.1",
-}
-``` 
-Please use yarn as package manager to install the above dependecies.
