-## Self-hosted knowledge base {#self-hosted}
-
-For self-hosted / on-premises deployments, you can enable the knowledge base features by setting `SELF_HOSTED_KNOWLEDGE_BASE=true` in the environment variables for your self-hosted docker image.
-
-You must also be running ChromaDB. Use image `chromadb/chroma:0.5.20`. In your CodeRabbit docker image environment variables, set `CHROMADB_URL` to point to the hostname where ChromaDB can be reached. For persistance of your ChromaDB data, mount `/chroma/chroma` in the container to a volume mount. For more information on ChromaDB docker deployment, including how to set up authentication, refer to the [official documentation](https://docs.trychroma.com/deployment/docker). CodeRabbit will use `CHROMA_CLIENT_AUTH_CREDENTIALS` if it is set.
 
-By default, CodeRabbit will store its data in the `coderabbitai/data` branch, unless you set a value for `SELF_HOSTED_KNOWLEDGE_BASE_BRANCH=<branch_name>`.

-### Walkthrough
-
-- Set up a ChromaDB service on your cloud provider of choice. There is extensive documentation for generic Docker deploys, as well as cloud native deployments, in the [official Chroma documentation](https://docs.trychroma.com/deployment)
-- Configure your environment variables for your CodeRabbit self-hosted deploy to be able to access Chroma. Documentation is available for [GitHub](/self-hosted/github#prepare-an-env-file).
-- Restart your CodeRabbit service so it has access to the new environment variable settings.
-- Create a new PR in your SCM platform.
-- Add a comment to the PR to tell CodeRabbit to remember something.

-- CodeRabbit should respond that it has added a learning.
-- Check out the branch called `coderabbit/data` in the repository (or whatever branch name you have set for `SELF_HOSTED_KNOWLEDGE_BASE_BRANCH`). It should contain a file called learnings.json with an entry containing what you told it to remember.
-- Future PRs should utilize the contents of this learnings file. Congratulations! You have configured the CodeRabbit Self-hosted knowledge base.
