+
+# Auto Glossary
+
+The documentation system includes an automatic glossary linker that converts marked terms into links pointing to the glossary page.
+
+## Quick Start
+
+Mark terms in your documentation using the marker format:
+
+```markdown
+Deploy {glossary:Gardenlinux} on {glossary:AWS} using {glossary:KVM}.
+```
+
+After aggregation, this becomes:
+
+```markdown
+Deploy [Gardenlinux](/reference/glossary#gardenlinux) on [AWS](/reference/glossary#aws) using [KVM](/reference/glossary#kvm).
+```
+
+## Function
+
+During aggregation (`make aggregate`), the system:
+
+1. Parses `docs/reference/glossary.md` to extract all level-3 headers as terms
+2. Extracts aliases from terms with parenthesized expansions (e.g., `ADR (Architecture Decision Record)`)
+3. Scans all markdown files for glossary markers
+4. Replaces markers with markdown links to glossary anchors
+5. Preserves code blocks, inline code, and existing links
+
+## Marking Terms
+
+Use the format where the term name matches a glossary entry:
+
+```markdown
+{glossary:AWS}
+{glossary:Garden Linux}
+{glossary:ADR (Architecture Decision Record)}
+```
+
+Term matching is case-insensitive but preserves your original formatting:
+
+- Input: `{glossary:aws}` produces `[aws](/reference/glossary#aws)`
+- Input: `{glossary:AWS}` produces `[AWS](/reference/glossary#aws)`
+
+::: details Developer Information
+The auto glossary system is designed to accept a new custom `entry_format` through which
+the shortcode `{glossary:*}` can be replaced with a new custom pattern.
+
+Check the source code for more information.
+:::
+
+## Protected Regions
+
+The system leaves certain content unchanged:
+
+- Fenced code blocks (triple backticks)
+- Inline code (single backticks)
+- Existing markdown links
+
+Glossary markers inside these regions are not processed.
+
+## Adding Glossary Terms
+
+To add a new term:
+
+1. Edit `docs/reference/glossary.md`
+2. Add a level-3 header:
+
+```markdown
+### New Term Name
+
+Definition of the term.
+```
+
+The anchor is generated automatically (lowercase, hyphens replace spaces). Reference it with the marker format in your documentation.
+
+## Alias Support
+
+Terms with parenthesized expansions create aliases automatically.
+
+Given this glossary entry:
+
+```markdown
+### ADR (Architecture Decision Record)
+```
+
+The system creates:
+- Main term: `ADR (Architecture Decision Record)`
+- Alias: `Architecture Decision Record`
+- Alias: `ADR`
+
+All three can be used in markers and link to the same glossary entry.
+
+## Auto-Linking
+
+
+
+Auto-linking creates links for glossary terms without requiring explicit markers. This feature is disabled by default.
+
+With auto-linking enabled, input text:
+
+```
+Deploy Gardenlinux on AWS using KVM virtualization.
+```
+
+Becomes:
+
+```markdown
+Deploy [Garden Linux](/reference/glossary#garden-linux) on [AWS](/reference/glossary#aws) using [KVM](/reference/glossary#kvm) virtualization.
+```
+
+Auto-linking rules:
+- Links only the first occurrence of each term
+- Matches longer terms first (`Garden Linux` before `Linux`)
+- Case-insensitive matching
+- Respects word boundaries
+- Preserves code blocks and inline code
+- Does not modify existing links
+
+::: warning
+This feature is disabled by default as it is highly experimental and intended for research work only.
+
+**Contributors must not rely on this feature when contributing documentation.**
+:::
+
+## Makefile Targets
+
+Process glossary links manually:
+
+```bash
+make glossary
+```
+
+Validate glossary structure:
+
+```bash
+make glossary-check
+```
+
+## Warnings
+
+**Term not found:**
+
+```
+[Warning][auto-glossary] Term 'xyz' not found in glossary (referenced in file.md)
+```
+
+The marker remains unchanged. Add the term to the glossary, fix the spelling, or remove the marker.
+
+**Anchor collision:**
+
+```
+[Warning][auto-glossary] Anchor collision detected:
+  'Term 1' and 'Term 2' both generate anchor 'term-1-2'
+```
+
+Rename one of the terms in the glossary.
+
+## Anchor Generation
+
+Terms are converted to VitePress-compatible anchors:
+
+- Convert to lowercase
+- Replace spaces and special characters with hyphens
+- Collapse consecutive hyphens
+- Strip leading and trailing hyphens
+- Normalize Unicode to ASCII
+
+Examples:
+- `AWS` becomes `aws`
+- `Garden Linux` becomes `garden-linux`
+- `ADR (Architecture Decision Record)` becomes `adr-architecture-decision-record`
+
+## Technical Reference
+
+Module location: `src/aggregation/auto_glossary.py`
+
+Main components:
+- `AutoGlossary` class for glossary processing
+- `process_glossary_links()` function for batch processing
+- `GLOSSARY_ENTRY_FORMAT` constant defining the default marker format
+
+Integration points:
+- Runs as part of `src/aggregate.py` after release notes generation
+- Makefile provides `glossary` and `glossary-check` targets
+
+## Testing
+
+Run the test suite:
+
+```bash
+python3 -m pytest tests/unit/test_auto_glossary*.py tests/unit/test_generate_anchor.py -v
+```
+
+Test coverage includes format validation, anchor generation, alias extraction, auto-linking, and integration tests.
