 ### Training with prior-preservation loss
 
 Prior-preservation is used to avoid overfitting and language-drift. Refer to the paper to learn more about it. For prior-preservation we first generate images using the model with a class prompt and then use those during training along with our data.

+# Research projects
+
+This folder contains various research projects using 🧨 Diffusers. 
+They are not really maintained by the core maintainers of this library and often require a specific version of Diffusers that is indicated in the requirements file of each folder. 
+Updating them to the most recent version of the library will require some work.
+
+To use any of them, just run the command
+
+```
+pip install -r requirements.txt
+```
+inside the folder of your choice.
+
+If you need help with any of those, please open an issue where you directly ping the author(s), as indicated at the top of the README of each folder.
