+#### sh.zip(zipfile, paths, [options], callback)]<a name="zip"></a>
+
+Creates a zip archive named `zipfile` using the paths (files, dirs) listed in `paths`.
+Valid options include `recursive=true`, which when set, causes directories to be followed
+deeply. The `paths` argument must either be a single path (String) or a list of paths
+(Array of String). The zip archive file, named in `zipfile`, must not exist or an error
+will be returned on the callback. The callback receives `(error)`.
+
+Examples:
+
+```javascript
+// Compress a single file
+sh.zip('/data.zip', '/data.txt', function(err) {
+  if(err) throw err;
+  // /data.zip is now the compressed archive of /data.txt
+});
+
+// Compress multiple files
+sh.zip('/data.zip', ['/data.txt', '/data2.txt'], function(err) {
+  if(err) throw err;
+  // /data.zip is now the compressed archive of /data.txt and /data2.txt
+});
+
+// Compress the entire filesystem, starting at the root /
+sh.zip('/fs-backup.zip', '/', { recursive: true }, function(err) {
+  if(err) throw err;
+  // /fs-backup.zip now contains the entire filesystem
+});
+```
+
+#### sh.unzip(zipfile, [options], callback)]<a name="zip"></a>
+
+Extracts files and directories from a zip archive named `zipfile`. If `zipfile` does not
+exist, an error is returned on the callback. Valid options include `destination`, which
+is the path to use when extracting the files (defaults to the shell's current working directory).
+If an optional `destination` path is specified, it must first exist. The callback receives `(error)`.
+
+Examples:
+
+```javascript
+// Extract files in /backup.zip to the current directory
+sh.unzip('/backup.zip', function(err) {
+  if(err) throw err;
+  // The current working directory now contains all files archived in backup.zip
+});
+
+// Extract files in /backup.zip to the /backup directory
+sh.mkdirp('/backup', function(err) {
+  if(err) throw err;
+
+  sh.unzip('/backup.zip', { destination: '/backup' }, function(err) {
+    if(err) throw err;
+    // The current working directory now contains all files archived in backup.zip
+  });
+});
