 Keystore.swift makes it easy to extract private keys from Ethereum keystore files and generate keystore files from existing private keys.    
 This library belongs to our Swift Crypto suite. For a pure Swift Ethereum Web3 library check out [Web3.swift](https://github.com/Boilertalk/Web3.swift)!
 
+This library also supports EIP 2335 (BLS/ETH2) keystores.

 ## Example
 
 Check the usage below or look through the repositories tests.
 
 ## Installation
 
-### CocoaPods
-
-Keystore is available through [CocoaPods](http://cocoapods.org). To install
-it, simply add the following line to your `Podfile`:
-
-```ruby
-pod 'Keystore'
-```
-
-### Carthage
-
-Keystore is compatible with [Carthage](https://github.com/Carthage/Carthage), a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To install it, simply add the following line to your `Cartfile`:
-
-```
-github "Boilertalk/Keystore.swift"
-```
-
-You will also have to install the dependencies, which can be found in our [Cartfile](Cartfile).
+We only support Swift Package Manager. Everything else is outdated.
 
 ### Swift Package Manager
 
-Keystore is compatible with Swift Package Manager v4 (Swift 4 and above). Simply add it to the dependencies in your `Package.swift`.
+Keystore is compatible with Swift Package Manager v5 (Swift 5 and above). Simply add it to the dependencies in your `Package.swift`.
