 And here comes SWCompression: no Objective-C, pure Swift.
 
 ### Features
-- Deflate decompression
-- GZip unarchiving
-- Zlib unarchiving
+- Decompress data which were compressed with DEFLATE algorithm.
+- Extract data from GZip archives.
+- Unarchive zlib compressed data.
 - _Swift only_
 
 By the way, it seems like GZip and Deflate decompressor implementations are specification compliant.

 ### Usage
+If you'd like to decompress "deflated" data just use:
+```swift
+let data = try! Data(contentsOf: URL(fileURLWithPath: "path/to/file"))
+let decompressedData = try? Deflate.decompress(compressedData: data)
+```
+**Note:** you should properly handle possible errors in loading data from file
+and define yourself if you need any `Data.ReadingOptions`.
+
+However, it is unlikely that you will encounter deflated data outside of any archive.
+So, in case of GZip archive you should use:
+```swift
+let decompressedData = try? GzipArchive.unarchive(archiveData: data)
+```
+
+And, finally, for zlib the corresponding code is:
+```swift
+let decompressedData = try? ZlibArchive.unarchive(archiveData: data)
+```
+
+One final note: every unarchive/decompress function can throw an error and
+you are responsible for handling them.
