# Lint sphinx documentation and fix broken links This PR lints multiple warnings shown in generation of the project documentation (using "make docs_linkcheck" and "make docs_build"). Additionally documentation internal links to (now?) non-existent files are modified to point to existing documents as it seemed the new correct target. The documentation is not updated content wise. There are no source code changes. Fixes # (issue) - broken documentation links to other files within the project - sphinx formatting (linting) ## Before submitting No source code changes, so no new tests added. --------- Co-authored-by: Dev 2049 <dev.dev2049@gmail.com>

"# Async API for Chain\n",

"LangChain provides async support for Chains by leveraging the [asyncio](https://docs.python.org/3/library/asyncio.html) library.\n",
|
|
"\n",
|

"Async methods are currently supported in `LLMChain` (through `arun`, `apredict`, `acall`) and `LLMMathChain` (through `arun` and `acall`), `ChatVectorDBChain`, and [QA chains](../index_examples/question_answering.ipynb). Async support for other chains is on the roadmap."
