 # SSZipArchive
 
-SSZipArchive is a simple utility class for unzipping files based on [ZipArchive](http://code.google.com/p/ziparchive).
+SSZipArchive is a simple utility class for zipping and unzipping files. Features:
 
-Currently it only supports unzipping. In the future, creating zip files will be supported.
+* Unzipping zip files
+* Unzipping password protected zip files
+* Creating zip files
+* Appending to zip files
+* Zipping files
+* Zipping NSData with a filename
 
 ## Adding to your project
 
-1. Add `SSZipArchive.h`, `SSZipArchive.m`, and `minizip` to your project.
+1. Add the `SSZipArchive` and `minizip` folders to your project.
 2. Add the `libz` library to your target
 
+SSZipArchive requires ARC.
+
 ## Usage
 
-```objective-c
-NSString *path = @"path_to_your_zip_file";
-NSString *destination = @"path_to_the_folder_where_you_want_it_unzipped";
-[SSZipArchive unzipFileAtPath:path toDestination:destination];
+``` objective-c
+// Unzipping
+NSString *zipPath = @"path_to_your_zip_file";
+NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
+[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
+
+// Zipping
+NSString *zippedPath = @"path_where_you_want_the_file_created";
+NSArray *inputPaths = [NSArray arrayWithObjects:
+                       [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],
+                       [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]
+                       nil];
+[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];
 ```
 
+## Tests
+
+Simply, open the Xcode 5 or higher project in the Tests directory and press Command-U to run the tests.

+
+    Oct-2009 - Defined ZPOS64_T to fpos_t on windows and u_int64_t on linux. (might need to find a better why for this)
+    Oct-2009 - Change to fseeko64, ftello64 and fopen64 so large files would work on linux.
+               More if/def section may be needed to support other platforms
+    Oct-2009 - Defined fxxxx64 calls to normal fopen/ftell/fseek so they would compile on windows.
+                          (but you should use iowin32.c for windows instead)
