 # CGManifest Files
 This directory contains CGManifest (cgmanifest.json) files.
-See [here](https://docs.opensource.microsoft.com/tools/cg/cgmanifest.html) for details.
-
-## `cgmanifests/generated/cgmanifest.json`
-This file contains generated CGManifest entries.
-
-It covers these dependencies:
-- git submodules
-- dependencies from the Dockerfile `tools/ci_build/github/linux/docker/Dockerfile.manylinux2014_cuda11`
-- the entries in [../cmake/deps.txt](../cmake/deps.txt)
-
-If any of these dependencies change, this file should be updated.
-**When updating, please regenerate instead of editing manually.**
-
-### How to Generate
-1. Change to the repository root directory.
-2. Ensure the git submodules are checked out and up to date. For example, with:
-    ```
-    $ git submodule update --init --recursive
-    ```
-3. Run the generator script:
-    ```
-    $ python cgmanifests/generate_cgmanifest.py --username <xxx> --token <your_access_token>
-    ```
-
-Please supply your github username and access token to the script. If you don't have a token, you can generate one at https://github.com/settings/tokens. This is for authenticating with Github REST API so that you would not hit the rate limit.
-
-## `cgmanifests/cgmanifest.json`
-This file contains non-generated CGManifest entries. Please edit directly as needed.
+See [here](https://docs.opensource.microsoft.com/tools/cg/cgmanifest.html) for details.
