-Type: `boolean`  
+#### options
+
+Type: `object`
+
+##### interlaced
+
+Type: `boolean`\
 Default: `false`
 
 Interlace gif for progressive rendering.
 
+##### optimizationLevel

+Type: `number`\
+Default: `1`
 
-MIT © [imagemin](https://github.com/imagemin)
+Select an optimization level between `1` and `3`.
+
+> The optimization level determines how much optimization is done; higher levels take longer, but may have better results.
+
+1. Stores only the changed portion of each image.
+2. Also uses transparency to shrink the file further.
+3. Try several optimization methods (usually slower, sometimes better results)
+
+##### colors
+
+Type: `number`
+
+Reduce the number of distinct colors in each output GIF to num or less. Num must be between 2 and 256.
