+# GM
+GraphicsMagick for node
+
+## getting started
+First download and install "GraphicsMagick":http://www.graphicsmagick.org/
+
+## example:
+     
+    gm.convert(image.tempfile)
+      .size(120,120)
+      .resize(120,120)
+      .noProfile()
+      .name('/path/to/thumbnails/'+image.filename)
+      .write(function(err){
+        if (!err) print('done!')
+      }
+    
+or
+
+    gm.mogrify(image.tempfile)
+      .resize(250,400)
+      .format("png")
+      .size(250,400)
+      .dir('/path/to/out')
+      .noProfile()
+      .write(function(err){
+        if (!err) print('success!')
+      })
+
+## methods
+gm includes light support for the GraphicsMagick `convert` and `mogrify` commands.
+
+  - convert
+    - name
+    - size
+    - resize
+    - noProfile
+    - write
+    - makeArgs
+    - cmd
+    
+  - mogrify
+    - format
+    - dir
+    - createDir
+    - size
+    - resize
+    - noProfile
+    - write
+    - makeArgs
+    - cmd
+  
+  More docs coming soon.
