-This example trains a super-resolution network on the [BSD300 dataset](https://www2.eecs.berkeley.edu/Research/Projects/CS/vision/bsds/), using crops from the 200 training images, and evaluating on crops of the 100 test images. A snapshot of the model after every epoch with filename model*epoch*<epoch_number>.pth
+This example trains a super-resolution network on the [BSD300 dataset](https://www2.eecs.berkeley.edu/Research/Projects/CS/vision/bsds/), using crops from the 200 training images, and evaluating on crops of the 100 test images. A snapshot of the model after every epoch with filename `model_epoch_<epoch_number>.pth`.
 
 ## Example Usage:
 
 ### Train
 
-`python main.py --upscale_factor 3 --batchSize 4 --testBatchSize 100 --nEpochs 30 --lr 0.001`
+```bash
+python main.py --upscale_factor 3 --batchSize 4 --testBatchSize 100 --nEpochs 30 --lr 0.001
+```
 
 ### Super Resolve
 
-`python super_resolve.py --input_image dataset/BSDS300/images/test/16077.jpg --model model_epoch_500.pth --output_filename out.png`
+```bash
+python super_resolve.py --input_image dataset/BSDS300/images/test/16077.jpg --model model_epoch_30.pth --output_filename out.png
+```
