+# SSZipArchive
+
+ZipArchive is a simple utility class for zipping and unzipping files on iOS and Mac.
+
+- Unzip zip files;
+- Unzip password protected zip files;
+- Create new zip files;
+- Append to existing zip files;
+- Zip files;
+- Zip-up NSData instances. (with a filename)
+
+## Installation and Setup
+
+### CocoaPods
+
+`pod install SSZipArchive`
+
+### Manual
+
+1. Add the `SSZipArchive` and `minizip` folders to your project.
+2. Add the `libz` library to your target
+
+SSZipArchive requires ARC.
+
+## Usage
+
+### Objective-C
+
+```objective-c
+// Create
+[SSZipArchive createZipFileAtPath: zipPath withContentsOfDirectory: sampleDataPath];
+
+// Unzip
+[SSZipArchive unzipFileAtPath:zipPath toDestination: unzipPath];
+```
+
+### Swift
+
+```swift
+// Create
+SSZipArchive.createZipFileAtPath(zipPath, withContentsOfDirectory: sampleDataPath)
+
+// Unzip
+SSZipArchive.unzipFileAtPath(zipPath, toDestination: unzipPath)
+```

-# SSZipArchive
-
-SSZipArchive is a simple utility class for zipping and unzipping files. Features:
-
-* Unzipping zip files
-* Unzipping password protected zip files
-* Creating zip files
-* Appending to zip files
-* Zipping files
-* Zipping NSData with a filename
-* Works in ARC and non-ARC projects
-
-## Adding to your project
-
-1. Add `SSZipArchive.h`, `SSZipArchive.m`, and `minizip` to your project.
-2. Add the `libz` library to your target
-
-You don't need to do anything regarding ARC. SSZipArchive will detect if you're not using ARC and add the required memory management code.
-
-## Usage
-
-``` 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];
-```

+# China to ban ivory trade
+
+**HONG KONG** — It could be the beginning of the end for the illicit trade in ivory.
+
+Last month, on a state visit to Washington, Chinese President Xi Jinping promised to stop the commercial trade in ivory in his country but gave few details about the timing and extent of such a move.
+
+Now, a senior U.S. government official says that the Chinese ban could be in place within a year or so, with very narrow exceptions, describing it as a “huge” deal.
+
+Such a move, conservationists say, would be a major step toward ending the poaching crisis that is decimating Africa’s elephant herds.

+# Kerry in Syria
+
+**VIENNA** — The war raging in Syria took center stage for Secretary of State John F. Kerry on Friday as he kicked off a series of meetings with diplomats seeking common ground on a strategy to resolve the grinding conflict.
+
+But the foreign ministers of the three countries meeting with Kerry — Russia, Saudi Arabia and NATO-member Turkey — carry sharply competing views on how to proceed.
+
+Saudi Arabia and Turkey, the neighboring country that has been overwhelmed with Syrian refugees, agree with Washington that Syrian President Bashar Al-Assad should eventually leave power.
+
+Moscow is one of Assad’s biggest backers, and in recent weeks has positioned its military in Syria and conducted heavy airstrikes that have allowed Assad’s forces to resume ground offensives. The Russian military intervention also has alarmed the Pentagon, which is leading a separate air campaign against the Islamic State.
