-# Controlnet
+# Controlnet - *Canny Version*
 
-Controlnet is an auxiliary model which augments pre-trained diffusion models with an additional conditioning.
+ControlNet is a neural network structure to control diffusion models by adding extra conditions. 
+This checkpoint corresponds to the ControlNet conditioned on **Canny edges**.
 
-Controlnet comes with multiple auxiliary models, each which allows a different type of conditioning
+It can be used in combination with [Stable Diffusion](https://huggingface.co/docs/diffusers/api/pipelines/stable_diffusion/text2img).
 
-Controlnet's auxiliary models are trained with stable diffusion 1.5. Experimentally, the auxiliary models can be used with other diffusion models such as dreamboothed stable diffusion.

-The auxiliary conditioning is passed directly to the diffusers pipeline. If you want to process an image to create the auxiliary conditioning, external dependencies are required.

-## HED Boundary
+## Introduction
 
-### Diffusers
+Controlnet was proposed in [*Adding Conditional Control to Text-to-Image Diffusion Models*](https://arxiv.org/abs/2302.05543) by 
+Lvmin Zhang, Maneesh Agrawala.
 
-Install the additional controlnet models package.
+The abstract reads as follows:
+
+*We present a neural network structure, ControlNet, to control pretrained large diffusion models to support additional input conditions. 
+The ControlNet learns task-specific conditions in an end-to-end way, and the learning is robust even when the training dataset is small (< 50k). 
+Moreover, training a ControlNet is as fast as fine-tuning a diffusion model, and the model can be trained on a personal devices. 
+Alternatively, if powerful computation clusters are available, the model can scale to large amounts (millions to billions) of data. 
+We report that large diffusion models like Stable Diffusion can be augmented with ControlNets to enable conditional inputs like edge maps, segmentation maps, keypoints, etc. 
+This may enrich the methods to control large diffusion models and further facilitate related applications.*
+
+## Released Checkpoints
+
+The authors released 8 different checkpoints, each trained with [Stable Diffusion v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) 
+on a different type of conditioning:

+## Example
+
+It is recommended to use the checkpoint with [Stable Diffusion v1-5](https://huggingface.co/runwayml/stable-diffusion-v1-5) as the checkpoint 
+has been trained on it.
+Experimentally, the checkpoint can be used with other diffusion models such as dreamboothed stable diffusion.
+
+**Note**: If you want to process an image to create the auxiliary conditioning, external dependencies are required as shown below:
+
+1. Install https://github.com/patrickvonplaten/controlnet_aux
 
 ```sh
-$ pip install git+https://github.com/patrickvonplaten/controlnet_aux.git
+$ pip install controlnet_aux
 ```
 
+2. Let's install `diffusers` and related packages:
+
+```
+$ pip install diffusers transformers accelerate
+```
+
+3. Run code:
+
 ```py
 from PIL import Image
 from diffusers import StableDiffusionControlNetPipeline, ControlNetModel, UniPCMultistepScheduler
