 ## Stable Diffusion Community Pipelines
 
-The release of Stable Diffusion as an open source model has fostered a lot of interesting ideas and experimentation. Our [Community Examples folder](https://github.com/huggingface/diffusers/tree/main/examples/community) contains many ideas worth exploring, like interpolating to create animated videos, using CLIP Guidance for additional prompt fidelity, term weighting, and much more! [Take a look](https://huggingface.co/docs/diffusers/using-diffusers/custom_pipeline_overview) and [contribute your own](https://huggingface.co/docs/diffusers/using-diffusers/contribute_pipeline).

+# Using Diffusers for reinforcement learning
+
+Support for one RL model and related pipelines is included in the `experimental` source of diffusers.

+To try some of this in colab, please look at the following example:
