+## Welcome to the course on diffusion models 🤗 !
+
+## What to expect?
+
+In this free course, you will:
+- 👩‍🎓 Study the theory behind diffusion models
+- 🧨 Learn how to generate images and audio with the popular 🤗 Diffusers library
+- 🏋️‍♂️ Train your own diffusion models from scratch
+- 📻 Fine-tune existing diffusion models on new datasets
+- 🗺 Explore conditional generation and guidance
+- 🧑‍🔬 Create your own custom diffusion model pipelines
+
+
+## Prérequis
+This course requires a good level in Python and a grounding in deep learning and Pytorch.
+If it's not the case yet, you can check these free resources:
+- Python: https://www.udacity.com/course/introduction-to-python--ud1110
+- Intro to Deep Learning with PyTorch: https://www.udacity.com/course/deep-learning-pytorch--ud188
+- PyTorch in 60min: https://pytorch.org/tutorials/beginner/deep_learning_60min_blitz.html
+
+To upload your models to the Hugging Face Hub, you'll need an account. You can create one for free at the following address: [https://huggingface.co/join](https://huggingface.co/join).

+	
+## What is the syllabus?
+
+The course consists in four units. Each unit is made up of a theory section, which also lists resources/papers, and two *notebooks*. More specifically, we have:
+- Unit 1: Introduction to diffusion models  
+Introduction to 🤗 Diffusers and implementation from 0
+- Unit 2: Finetuning and guidance  
+Finetuning a diffusion model on new data and adding guidance.
+- Unit 3: Stable Diffusion  
+Exploring a powerful text-conditioned latent diffusion model
+- Unit 4: Doing more with diffusion  
+Advanced techniques for going further with diffusion
