+## Adding new dependencies
+
+If you want to add a new dependency to the buildpack, please add it to the [config.yml](https://github.com/cloudfoundry/buildpacks-ci/blob/5a63d13df09f83d5dff7c71d0a12c3e2dc798d39/pipelines/dependency-builds/config.yml#L272) file. For example, if you want to add a new version of Python, add an entry like the following:
+
+```yaml
+python:
+  lines:
+    - line: 3.14.X
+      deprecation_date: 2030-10-07
+      link: https://peps.python.org/pep-0745/
+```
+
+The new dependency will be automatically added to the buildpack [manifest.yml](manifest.yml) file.
