# Inkhaven Documentation
You are in the project's `Documentation/` directory. This is the canonical
home for everything beyond the source code: how to install Inkhaven, how
to configure it, how to write with it, how to keep its database healthy,
and how to extend its prompt / knowledge-base systems.
The README at the [repository root](../README.md) gives a one-page
overview and the rationale; this folder is where you go after that.
## Start here
If you have never run Inkhaven before, follow these in order:
1. [**FIRST_STEPS.md**](FIRST_STEPS.md) — install the Rust toolchain,
build the binary, create your first project, and learn the bare
minimum needed to write a paragraph.
2. [**Tutorials/**](Tutorials/) — narrative walk-throughs, each focused
on one workflow. See [`Tutorials/README.md`](Tutorials/README.md) for
a guided reading order.
3. [**KEYBINDING.md**](KEYBINDING.md) — keep open in another window;
it is the reference for every keystroke in every pane.
## Reference manuals
These are detail-heavy lookup documents — read once for orientation, then
return whenever you need to remember a specific knob.
| [`CONFIGURATION.md`](CONFIGURATION.md) | Every field in the project's `inkhaven.hjson`: embeddings, LLM providers, editor, theme, keys, hierarchy, backup, language, snowball stemmers. Includes valid value ranges and default values. |
| [`KEYBINDING.md`](KEYBINDING.md) | Every keystroke the TUI honours, organised by pane (Tree / Editor / AI / Search / AI prompt) and overlay (file picker, prompt picker, modal stack). Mouse semantics included. |
| [`KEYS_REASSIGNMENT.md`](KEYS_REASSIGNMENT.md) | Rebind chords via `keys.bindings` in HJSON or via the `ink.key.*` Bund stdlib. Includes the full action table. |
| [`MAINTENANCE.md`](MAINTENANCE.md) | Backup, restore, auto-backup-on-exit, the `reindex` command, log files, recovering from drift, troubleshooting first-run model downloads. |
| [`Bund/`](Bund/README.md) | Bund — the embedded scripting language. Hook lambdas (`hook.on_save`, …), the `ink.*` stdlib, sandbox policy, `.bund` Script nodes. Start at [`Bund/BUND_TUTORIAL.md`](Bund/BUND_TUTORIAL.md). |
## Topic guides
These describe the parts of Inkhaven that have their own mental model.
Read the topic guide when you reach a workflow that depends on it; you
don't need them all up front.
| [`PROMPTS.md`](PROMPTS.md) | Writing reusable prompt templates: the `prompts.hjson` system library, the `Prompts` system book for project-local prompts, `{{selection}}` / `{{context}}` substitutions, and the picker UI. |
| [`LOCATIONS.md`](LOCATIONS.md) | Managing the **Places** system book: how to record locations, how the editor highlights them in your prose, and how to ask the AI about a place via `Ctrl+B P`. |
| [`CHARACTERS.md`](CHARACTERS.md) | Same model as `LOCATIONS.md` but for the **Characters** system book. Yellow-highlight overlay, `Ctrl+B C` RAG inference, multilingual stemming. |

Three leaf kinds live under `books/<...>/`:
- **`.typ`** — Paragraph (default). Typst source; the canonical
form of your prose. Versionable with git, renderable with
`typst compile`.
- **`.hjson`** — Paragraph with `content_type=hjson`. Structured
data nodes (worldbuilding tables, prop catalogs, etc.).
- **`.bund`** — Script node. Bund source evaluated into the Adam
VM at project open. See [`Bund/`](Bund/README.md).
`inkhaven reindex` reconciles disk against the DuckDB blob store
when something drifts (see [`MAINTENANCE.md`](MAINTENANCE.md)).
Images are stored binary in `blobs.db` and shipped to disk as
`.png` / `.jpg` / `.webp` working copies on assembly.
## The hierarchy
```
Book → Chapter → Subchapter → Paragraph
```
Exactly four levels by default. `Paragraph` is the leaf (a `.typ` file on
disk); the other three are directories. Paragraphs can attach to **any**
branch level — that is how prefaces, chapter intros, and afterwords are
represented (paragraphs attached directly to the book or chapter rather
than buried in a subchapter).
To allow arbitrary subchapter nesting, set in `inkhaven.hjson`:
```hjson
hierarchy: { unbounded_subchapters: true }
```
Each node has a stable UUIDv7, a slug, an `order` integer (which controls
both display order in the Tree pane and the on-disk `NN-` filename
prefix), and a parent pointer. Names like `01-preface.typ` and
`02-the-beginning/` sort correctly under `ls`.
### Nine system books
Every project ships with nine pre-seeded books at the top of the tree,
in this order:
| **Notes** | Editorial notes, TODOs, marginalia | Word-matches in prose underlined; `Ctrl+B G` queries this book |
| **Research** | Background research kept alongside the manuscript | Plain user book |
| **Prompts** | Project-local AI prompt templates | Surfaced in the `/` picker (see [PROMPTS.md](PROMPTS.md)) |
| **Places** | Locations referenced by the prose | Names light up in cyan; `Ctrl+B P` queries this book (outside `#image(...)`) ([LOCATIONS.md](LOCATIONS.md)) |
| **Characters** | Characters referenced by the prose | Names light up in yellow; `Ctrl+B C` queries this book ([CHARACTERS.md](CHARACTERS.md)) |
| **Artefacts** | Objects, items, worldbuilding props | Names light up in peach; `Ctrl+B Y` queries this book (added in 1.1) |
| **Typst** | Per-user-book Typst skeleton (globals / settings / index) | Read/write; auto-seeded for every new user book (added in 1.1) |
| **Scripts** | Bund scripts (`.bund`) loaded into the Adam VM at startup | Default home for project-global hooks / chord rebinds; `Ctrl+Z N` creates a new script (added in 1.2) — see [`Bund/`](Bund/README.md) |
| **Help** | Inkhaven's own help manual, queryable from F1 | Read-only; populated via `inkhaven import-help` or `inkhaven import-typst-help` |
User-added books are inserted **above** Notes — the system block stays
pinned at the bottom of the root level so your own work always sits on top.
