+
+Image Editor Plus is a Blender add-on that lets you modify your image in seconds. Clear, fill, flip, rotation, adjusting colors, and applying some filters in just a few clicks without external editors such as PhotoShop or Gimp.
+
+This add-on extends the UV/Image Editor in Blender and provides the following operations.
+
+- Cut/Copy/Paste
+- Clear, Fill
+- Crop
+- Adjust hue/saturation
+- Adjust brightness/contrast
+- Adjust gamma
+- Adjust color curve
+- Replace color
+- Flip, Rotate
+- Canvas size
+- Offset
+- Apply filters
+
+NOTE: Currently, text editing is provided as a separate add-on: [Image Editor+ Text Tool](https://superhivemarket.com/products/imedp-text-tool)
+
+These image operations can be applied to packed/unpacked images, and reflected to the 3D model view immediately.
+
+You can make a selection to edit the desired area on your image (currently only rectangle selection supported).
+
+![Adjust color](doc/images/adjust_color.png)
+
+It's easy to copy/paste a selection or an entire image. The pasted images are displayed as layers, and they can be moved, rotated or scaled.
+
+NOTE: To display pasted layers in the 3D View, you need to use a [Image Layers Node](https://superhivemarket.com/products/image-layers-node) instead of built-in Texture Node.
+
+![Pasted layers](doc/images/pasted_layers_2.png)
+
+## Filters
+
+By applying the some filters, you can add special effects to your images.
+
+- Blur
+- Sharpen
+- Add noise
+- Pixelize (Mosaic)
+- Make seamless
+- Normal map
+
+"Make seamless" filter is useful for making your image tileable. 
+
+![Filters](doc/images/filters.png)
+
+## Normal Map Generator
+
+Normal Map is a texture where every pixel represents a normal vector and is used to add bumps to a surface.
+
+This add-on uses a height map (black: low, white: high) as input and can convert it to a normal map.
