+## Usage
+
+### Using the module in your Bazel project
+
+To use `score_docs_as_code` in your Bazel project, add the following to your `MODULE.bazel`:
+
+```starlark
+bazel_dep(name = "score_docs_as_code", version = "...")
+
+# Use the setup extension to access transitive dependencies
+use_extension("@score_docs_as_code//setup:setup.bzl", "setup")
+use_repo(setup, "score_python_basics")
+```
+
+This pattern allows you to use the `docs()` macro and other utilities without manually declaring all transitive dependencies like `score_python_basics` in your own `MODULE.bazel`.

+# Verification Steps for Setup Extension
+
+This document outlines how to verify that the setup extension works correctly.
+
+## Manual Testing Steps
+
+### 1. Create a test downstream project
+
+Create a new directory with the following structure:
+
+```
+test-downstream-project/
+├── MODULE.bazel
+├── BUILD
+└── test.py
+```
+
+### 2. Add MODULE.bazel content
+
+```starlark
+module(name = "test_downstream", version = "1.0.0")
+
+bazel_dep(name = "score_docs_as_code", version = "0.4.0")
+
+# Use the setup extension to access transitive dependencies
+use_extension("@score_docs_as_code//setup:setup.bzl", "setup")
+use_repo(setup, "score_python_basics")
+```
+
+### 3. Add BUILD content
+
+```starlark
+load("@score_python_basics//:defs.bzl", "score_py_pytest")
+
+score_py_pytest(
+    name = "test",
+    srcs = ["test.py"],
+)
+```
+
+### 4. Add test.py content
+
+```python
+def test_works():
+    assert True
+```
+
+### 5. Verify the build works
+
+Run: `bazel test //:test`
+
+If successful, this confirms that:
+- The setup extension properly exposes score_python_basics
+- Downstream projects don't need to manually declare score_python_basics
+- The transitive dependency resolution works correctly
+
+### 6. Verify documentation macro usage
+
+Create a docs example in the test project:
+
+```starlark
+load("@score_docs_as_code//:docs.bzl", "docs")
+
+docs(
+    conf_dir = "docs",
+    source_dir = "docs", 
+    docs_targets = [{"suffix": ""}],
+    source_files_to_scan_for_needs_links = [],
+)
+```
+
+Run: `bazel run //:ide_support`
+
+This should work without any additional dependencies since score_python_basics is available via the extension.
+
+## Expected Behavior
+
+- ✅ Projects can use the docs() macro without manually declaring score_python_basics
+- ✅ Projects can use score_py_pytest and other utilities from score_python_basics
+- ✅ Projects can use score_virtualenv for IDE support
+- ✅ The extension follows Bazel best practices for modular dependencies

+## Using the Setup Extension for Transitive Dependencies
+
+The `score_docs_as_code` module provides a setup extension that allows downstream consumers to access transitive dependencies without explicitly declaring them. This follows Bazel best practices for modular, reusable modules.
+
+In your downstream project's `MODULE.bazel`:
+
+```starlark
+module(name = "my_project", version = "1.0.0")
+
+bazel_dep(name = "score_docs_as_code", version = "0.4.0")
+
+# Use the setup extension to access transitive dependencies
+use_extension("@score_docs_as_code//setup:setup.bzl", "setup")
+use_repo(setup, "score_python_basics")
+```
+
+This makes `@score_python_basics` available in your BUILD files without needing to add `bazel_dep(name = "score_python_basics")` to your MODULE.bazel. You can then use utilities like `score_py_pytest` and `score_virtualenv` from the `score_python_basics` module.
