 ## What This Project Does
 
-`pulp-docs` is a documentation aggregation tool for the Pulp Project ecosystem. It is a custom MkDocs plugin that builds a unified documentation website by pulling content from ~30+ separate Pulp component repositories (pulpcore, pulp_ansible, pulp_container, etc.) into a single site at https://pulpproject.org/.
+`pulp-docs` is a documentation tool for the Pulp Project ecosystem.
+Its main feature is aggregating repositories to build a single website.
 
-## Commands
+## Useful Commands
 
-**Linting:**
 ```bash
-make lint          # Run pre-commit hooks (ruff, yamllint, typos)
-```
-
-**Testing:**
-```bash
-pytest -sv         # Run all tests
-pytest -sv tests/test_openapi_generation.py  # Run a single test file
-```
-
-**Building the distribution:**
-```bash
-make dist-build    # Build wheel via python -m build
-make dist-test     # Test wheel in a venv with twine
-```
+make lint  # always run this after significant changes
+make docs-ci COMPONENT=pulpcore
 
-**Running the docs locally** (requires cloned component repos):
-```bash
-# 1. Clone required repos into a flat workspace (e.g., sibling of this repo)
-pulp-docs fetch --dest "../"
+uv run pytest -sv
+uv run pytest -svk tests/test_openapi_generation.py
 
-# 2. Serve or build (--path points to the directory containing all cloned repos)
+TMPDIR=$(mktemp -d)
+pulp-docs fetch --dest "$TMPDIR"
 pulp-docs serve --path ".."
 pulp-docs build --path ".." --blog --docstrings
 ```
-
-**Building docs for a single component's CI:**
-```bash
-make docs-ci COMPONENT=pulpcore        # Build component-specific docs
-```
-
-## Code Architecture
-
-### Entry Points
-- `pulp-docs` CLI → `pulp_docs.cli:main` (Click-based, wraps MkDocs CLI)
-- MkDocs plugin → `pulp_docs.plugin:PulpDocsPlugin` (registered as `PulpDocs` in pyproject.toml)
-
-### Core Modules (`src/pulp_docs/`)
-
-- **`plugin.py`** — The heart of the project. Contains the MkDocs plugin and all supporting classes:
-  - `PulpDocsPlugin` — MkDocs lifecycle hooks (`on_config`, `on_files`, `on_page_context`, `on_page_markdown`, `on_pre_page`)
-  - `ComponentLoader` — Discovers and loads component repos from configured lookup paths using `RepositoryFinder`
-  - `ComponentNav` — Builds per-component navigation (Tutorials, How-to Guides, Learn More, Reference sections)
-  - `DataExtractor` — Reads version from `pyproject.toml` and git metadata from component repos
-
-- **`cli.py`** — Click CLI that sets context variables (`ctx_path`, `ctx_blog`, `ctx_docstrings`, `ctx_draft`, `ctx_dryrun`) before delegating to MkDocs
-
-- **`context.py`** — `ContextVar` globals that pass CLI state into the MkDocs plugin without coupling them directly
-
-- **`openapi.py`** — Generates OpenAPI JSON schemas by creating a venv per plugin and running `pulpcore-manager openapi`
-
-### Configuration Flow
-
-```
-CLI flags (--path, --blog, --draft) → ContextVars → PulpDocsPlugin.on_config()
-→ ComponentLoader (finds repos on disk) → ComponentNav (builds navigation)
-→ MkDocs file/nav structure
-```
-
-### Component Discovery
-
-Components are defined in `mkdocs.yml` under the `plugins.PulpDocs` section. At build time, `ComponentLoader` uses `RepositoryFinder` to locate each component on disk by searching the configured `--path` lookup directories (format: `name@/path/to/dir:name2@/path2`).
-
-### Documentation Structure
-
-Static content lives in `pulpproject.org/` (home page, blog posts, admin docs, dev docs). Per-component docs are loaded dynamically from each component's own repository. The `custom/` directory holds MkDocs theme overrides.
-
-## Code Style
-
-- Python 3.12+, line length 100, double quotes
-- Ruff enforces `E`, `F`, `I` (isort), and `T100` (no breakpoints)
-- Run `make lint` before committing; pre-commit hooks enforce ruff, yamllint, and typo checks
