+
+## Running The Web Application
+
+Please edit the first line in `web.lua`.
+```
+local ROOT = '/path/to/waifu2x/dir'
+```
+Run.
+```
+th web.lua
+```
+
+View at: http://localhost:8812/
+
+## Command line tools
+
+### Noise Reduction
+```
+th waifu2x.lua -m noise -noise_level 1 -i input_image.png -o output_image.png
+```
+```
+th waifu2x.lua -m noise -noise_level 2 -i input_image.png -o output_image.png
+```
+
+### 2x Upscaling
+```
+th waifu2x.lua -m scale -i input_image.png -o output_image.png
+```
+
+### Noise Reduction + 2x Upscaling
+```
+th waifu2x.lua -m noise_scale -noise_level 1 -i input_image.png -o output_image.png
+```
+```
+th waifu2x.lua -m noise_scale -noise_level 2 -i input_image.png -o output_image.png
+```
+
+See also `images/gen.sh`.
+
+## Training Your Own Model
+
+### Data Preparation
+
+Genrating a file list.
+```
+find /path/to/image/dir -name "*.png" > data/image_list.txt
+```
+(You should use PNG! In my case, waifu2x is trained by 3000 PNG images.)
+
+Converting training data.
+```
+th convert_data.lua
+```
+
+### Training a Noise Reduction(level1) model
+
+```
+th train.lua -method noise -noise_level 1 -test images/miku_noise.png
+th cleanup_model.lua -model models/noise1_model.t7 -oformat ascii
+```
+You can check the performance of model with `models/noise1_best.png`.
+
+### Training a Noise Reduction(level2) model
+
+```
+th train.lua -method noise -noise_level 2 -test images/miku_noise.png
+th cleanup_model.lua -model models/noise2_model.t7 -oformat ascii
+```
+You can check the performance of model with `models/noise2_best.png`.
+
+### Training a 2x Upsclaing model
+
+```
+th train.lua -method scale -scale 2 -test images/miku_small.png
+th cleanup_model.lua -model models/scale2.0x_model.t7 -oformat ascii
+```
+You can check the performance of model with `models/scale2.0x_best.png`.
