Description

Hi, I found that the relevant documents of LCEL do not have a separate document page in langchain. Moreover, through the search box or by asking the AI within the langchain site, the documents provided by the AI within the site still cannot be accessed. Later, after using Google search, I found the relevant documents and usage of LCEL in the community and the documents of various bloggers. May I ask if you are considering adding it in the future? Looking forward to your reply. Thank you!

LCEL is no longer a recommended pattern. I think much of what you may want is still accessible via the reference docs for Runnable and its related classes: https://reference.langchain.com/python/langchain_core/runnables/
