 ##### CocoaPods
 Add to your Podfile `pod 'SWCompression'`.
 
+Since 1.1.0 version of SWCompression there are several sub-podspecs
+if you need only parts of functionality of SWCompression.
+There are `pod 'SWCompression/GZip'`, `pod 'SWCompression/Zlib'`, `pod 'SWCompression/Deflate'` and `pod 'SWCompression/BZip2'` subspecs. You can add some or all of them instead of `pod 'SWCompression'`
+
 Also, do not forget to have `use_frameworks!` line in the Podfile.
 
 To complete installation, run `pod install`.
 
+_Note:_ Actually, there is one more subspec (SWCompression/Common) but it does not contain any end-user functions. This subspec is included in other subspecs such as SWCompression/GZip and should not be specified directly in Podfile.

 ##### Carthage
 Add to  your Cartfile `github "tsolomko/SWCompression"`.
