+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:
+
+.. code-block:: python
+
+   llms_txt_full_max_size = 10000  # Maximum 10,000 lines
+
+If the generated file would exceed this limit, the extension will skip its generation and show a warning, allowing the build to complete.
+
+.. tip:: Use :ref:`excluding_content` to remove less relevant pages.
+
+.. _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
+^^^^^^^^^^^^^^^^^
+
+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.
+
+.. _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.
+
+.. _integration_examples:
+
+Integration Examples
+^^^^^^^^^^^^^^^^^^^^
+
+Complete Configuration Example
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here's a complete example showing multiple :ref:`configuration-values`:
+
+.. code-block:: python
+
+   # File names and generation options
+   llms_txt_filename = "ai-summary.txt"
+   llms_txt_full_filename = "ai-full-docs.txt"
+   llms_txt_full_max_size = 50000
+
+   # Content customization
+   llms_txt_title = "Project Documentation for AI Assistants"
+   llms_txt_summary = """
+   This is a comprehensive documentation set for our project.
+   It includes API references, usage examples, and tutorials.
+   """
+
+   # Path handling
+   html_baseurl = "https://docs.example.com/"
+   llms_txt_directives = ["custom-image", "custom-include"]
+
+   # Content filtering
+   llms_txt_exclude = ["search", "genindex", "404", "private_*"]

+Getting Started
+===============
+
+Demo
+----
+
+You can see this Sphinx project's `llms.txt`_ and `llms-full.txt`_ files as a simple example.
+
+Installation
+------------
+
+Directly install via ``pip`` by using:
+
+.. code-block:: bash
+
+    pip install sphinx-llms-txt
+
+Usage
+-----
+
+Add the extension to your Sphinx configuration (``conf.py``):
+
+.. code-block:: python
+
+    extensions = [
+        'sphinx_llms_txt',
+    ]
+
+Once added, the extension will automatically generate the LLMs.txt files during the build process.
+
+See :doc:`advanced-configuration` for more information about how to use **sphinx-llms-txt**.
+
+How It Works
+-----------
+
+During the Sphinx build process:
+
+1. **Content Collection**: Scans all of your documentation's ``_source`` pages and collects their content
+2. **Directive Processing**: Resolves ``include`` directives by automatically incorporating their content
+3. **Path Resolution**: Transforms relative paths in directives to full paths
+4. **Output Generation**: Creates two optional files:
+
+   - ``llms.txt``: A concise summary of your documentation, in Markdown
+   - ``llms-full.txt``: A comprehensive version with all documentation content, in reStructuredText
+
+5. **Content Filtering**: Allows you to exclude specific pages from the generated files
