+Advanced Configuration
+======================
+
+This page covers advanced configuration options for the sphinx-llms-txt extension.
+
+.. _customizing_llms_files:
+
+Customizing the LLMs Files
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, the extension generates two files:
+
+1. ``llms.txt`` - A summary file in Markdown format
+2. ``llms-full.txt`` - A complete documentation file in reStructuredText format
+
+You can customize these files in several ways:
+
+.. _changing_filenames:
+
+Changing Filenames
+~~~~~~~~~~~~~~~~~~
+
+You can change the default filenames by setting these values in your ``conf.py``:
+
+.. code-block:: python
+
+   llms_txt_filename = "custom-summary.txt"
+   llms_txt_full_filename = "custom-docs.txt"
+
+.. _disabling_file_generation:
+
+Disabling File Generation
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you only want one of the files, you can disable generation of the other:
+
+.. code-block:: python
+
+   # Disable summary file
+   llms_txt_file = False
+
+   # Disable full documentation file
+   llms_txt_full_file = False
+
+.. _custom_summary:
+
+Adding a Custom Summary
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The summary file can include a custom description of your project:
+
+.. code-block:: python
+
+   llms_txt_summary = """
+   This documentation explains how to use MyProject to build amazing
+   applications. The project provides a comprehensive API for handling
+   data processing and visualization.
+   """
+
+.. note:: The summary can span multiple lines and will be properly formatted in the output file.
+
+.. _custom_title:
+
+Custom Title
+~~~~~~~~~~~~
+
+By default, the project name from Sphinx is used as the title in ``llms.txt``. You can override this:
+
+.. code-block:: python
+
+   llms_txt_title = "My Custom Project Documentation"
+
+.. _handling_large_documentation:
+
+Handling Large Documentation
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+For very large documentation sets, generating the full documentation file might exceed reasonable size limits.
+You can set a maximum line count and control what happens when that limit is exceeded:
+
+.. code-block:: python
+
+   llms_txt_full_max_size = 10000  # Maximum 10,000 lines
+   llms_txt_full_size_policy = "warn_skip"  # Default behavior
+
+The ``llms_txt_full_size_policy`` setting controls both the log level and action taken when the size limit is exceeded.
+It uses the format ``"<loglevel>_<action>"``:
+
+**Log levels:**
+- ``warn``: Log as a warning (default)
+- ``info``: Log as informational message
+
+**Actions:**
+- ``skip``: Don't create the file (default)
+- ``keep``: Create the file anyway, ignoring the size limit
+- ``note``: Create a placeholder file explaining why the full file wasn't generated
+
+.. tip:: Use :ref:`excluding_content` to remove less relevant pages and reduce the file size.
+
+.. _custom_directive_handling:
+
+Custom Directive Handling
+^^^^^^^^^^^^^^^^^^^^^^^^^
+
+.. _path_resolution:
+
+Path Resolution
+~~~~~~~~~~~~~~~
+
+The extension resolves paths in the common directives ``[ 'image', 'figure']`` by default.
+You can add custom directives to this list:
+
+.. code-block:: python
+
+   llms_txt_directives = [
+       "my-custom-image-directive",
+       "another-directive-with-paths",
+   ]
+
+This ensures that paths in your custom directives are properly resolved in the generated files.
+
+.. _excluding_content:
+
+Excluding Content
+^^^^^^^^^^^^^^^^^
+
+There are several ways to exclude content from the generated ``llms-full.txt`` file:
+
+.. _global_exclusion:
+
+Global Page Exclusion
+~~~~~~~~~~~~~~~~~~~~~~
+
+You can exclude specific pages from being included in the generated files:
+
+.. code-block:: python
+
+   llms_txt_exclude = [
+       "search",  # Exclude the search page
+       "genindex",  # Exclude the index page
+       "private_*",  # Exclude all pages starting with 'private_'
+   ]
+
+This is useful for excluding auto-generated pages, indexes, or content that isn't relevant for LLM consumption.
+It can also be used to reduce the size of llms-full.txt.
+
+.. _page_level_ignore:
+
+Page-Level Ignore Metadata
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can exclude individual pages by adding metadata at the top of any reStructuredText file:
+
+.. code-block:: restructuredtext
+
+   :llms-txt-ignore: true
+
+   Page Title
+   ==========
+
+   This entire page will be excluded from llms-full.txt
+
+When this metadata is present, the entire page is skipped during processing.
+
+.. _block_level_ignore:
+
+Block-Level Ignore Directives
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can exclude specific sections within a page using ignore directives:
+
+.. code-block:: restructuredtext
+
+   Page Title
+   ==========
+
+   This content will be included in llms-full.txt.
+
+   .. llms-txt-ignore-start
+
+   This content will be excluded from llms-full.txt.
+
+   Section To Ignore
+   -----------------
+
+   This entire section and any nested content will be ignored.
+
+   .. code-block:: python
+
+      # This code block will also be ignored
+      def ignored_function():
+          pass
+
+   .. llms-txt-ignore-end
+
+   This content will be included again.
+
+Block-level ignores can be useful for:
+
+- Removing internal notes or TODOs
+- Hiding implementation details while keeping user-facing documentation
+
+.. note::
+   - Multiple ignore blocks can be used within the same file
+   - Ignore directives work with any indentation level
+
+.. _including_code_files:
+
+Including Source Code Files
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+You can include source code files from your project at the end of :confval:`llms_txt_full_filename`.
+
+Use include/exclude syntax to precisely control which files are included:
+
+.. code-block:: python
+
+   llms_txt_code_files = [
+       "+:src/**/*.py",           # Include all Python files in src
+       "-:src/**/__pycache__/**", # Exclude Python cache files
+   ]
+
+Pattern syntax:
+
+- **+:pattern**: Include files matching the pattern. Processed first to collect matching files.
+- **-:pattern**: Exclude files matching the pattern. Applied to filter out unwanted files.
+
+Code files are processed as follows:
+
+- **Glob patterns**: Use standard glob patterns (``*``, ``**``, ``?``) to match files
+- **Relative paths**: Patterns are resolved relative to your Sphinx source directory
+- **Formatting**: Each file is presented with a title and syntax-highlighted code block
+
+.. _customizing_code_paths:
+
+Customizing Code File Paths
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default, the extension automatically detects the relative path from your Sphinx source directory to the git root and strips that prefix from displayed file paths. You can customize this behavior:
+
+.. code-block:: python
+
+   # Manually specify base path to strip
+   llms_txt_code_base_path = "../../"
+
+   # Disable path stripping entirely
+   llms_txt_code_base_path = ""
+
+This helps create cleaner, more readable file paths in the generated documentation.
+
+.. _using_html_baseurl:
+
+Using HTML Base URL
+^^^^^^^^^^^^^^^^^^^
+
+If you want to include absolute URLs for resources in your documentation, you can use Sphinx's built-in ``html_baseurl`` configuration:
+
+.. code-block:: python
+
+   html_baseurl = "https://example.com/docs/"
+
+When this option is set, all resolved paths in directives will be prefixed with this URL, creating absolute paths in the generated files.
+
+.. _customizing_uri_links:
+
+Customizing URI Links in llms.txt
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+By default, the ``llms.txt`` file links to source files in the ``_sources`` directory when available, falling back to HTML pages when sources aren't available.
+You can customize this behavior using URI templates with :confval:`llms_txt_uri_template`:
+
+.. code-block:: python

+
+.. _available_template_variables:
+
+Available Template Variables
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Your URI template can use the following variables:
+
+- ``{base_url}`` - The base URL from ``html_baseurl`` configuration (includes trailing slash)
+- ``{docname}`` - The document name (e.g., ``index``, ``guide/intro``)
+- ``{suffix}`` - The source file suffix (e.g., ``.rst``, ``.md``) - may be empty if no source file exists
+- ``{sourcelink_suffix}`` - The suffix from ``html_sourcelink_suffix`` configuration (e.g., ``.txt``)
+
+.. tip::
+   Instead of using the default of linking to ``_sources``, you can generate Markdown and/or reStructuredText files from your documentation and link to those in ``llms.txt``.
+   See :ref:`cmake_workflow` for an example of building both HTML and Markdown and/or reStructuredText in parallel.
+   Note that ``_sources`` is still needed for ``llms-full.txt`` at this time.
+
+.. _cmake_workflow:
+
+CMake Workflow
+^^^^^^^^^^^^^^
+
+This project uses CMake to orchestrate documentation builds across multiple output formats, serving as a simple demo of the functionality.
+This approach enables parallel builds and integrates well with CI/CD platforms like Read the Docs.
+
+Building multiple formats allows you to compare what works best for your docs, as well as allows users to choose which format to feed to their LLM.
+Use :confval:`llms_txt_uri_template` to configure links to point to your preferred format.

+Sphinx llms.txt Generator
+=========================
+
+A `Sphinx`_ extension that generates a summary ``llms.txt`` file, written in Markdown, and a single combined documentation ``llms-full.txt`` file, written in reStructuredText.
+
+|PyPI version| |Conda Version| |Downloads| |Parallel Safe| |GitHub Stars|
+
+Demo
+----
+
+This Sphinx project's `llms.txt`_ and `llms-full.txt`_ files as an example of the default output format.
+
+Alternative :ref:`output formats <choosing-output-format>` are also available. For example: `Markdown`_ and `reStructuredText`_.
+
+Highlights
+----------
+
+**Zero Configuration**
+   Add the extension to your ``conf.py`` and you're done.
+   The extension automatically collects your documentation and generates both ``llms.txt`` and ``llms-full.txt`` during your normal Sphinx build.
+
+**Intelligent Content Processing**
+   Automatically resolves ``include`` directives, transforms relative paths, and handles your documentation structure without manual intervention.
+
+**Customizable When Needed**
+   Filter content, include source code files, or integrate with alternative output formats like Markdown for even better LLM compatibility.
+   See :doc:`getting-started` for output format options and :doc:`configuration-values` for all settings.
+
+.. seealso::
+
+   For better default output without configuration, see `sphinx-llm <https://github.com/NVIDIA/sphinx-llm>`_ from NVIDIA.
+   sphinx-llms-txt is best when customized with alternative output formats, content filtering, or source code inclusion.

 """
-Sphinx extension to create a combined sources file (llms-full.txt)
+Sphinx extension that generates llms.txt and llms-full.txt files for LLM consumption.
+
+This extension collects documentation content from Sphinx projects and generates
+two output files:
+- llms.txt: A concise Markdown summary with project overview and page links
+- llms-full.txt: A comprehensive reStructuredText file containing all documentation
+  content with resolved includes and path references
+
+The extension processes content during the build phase, handles page-level and
+block-level ignore directives, and can optionally include source code files.
