# Editing documents in DocInject

> Use the document editor to build and refine a node tree of sections, steps, and sub-steps with rich text content, drag-and-drop reordering, and auto-save.

The document editor is where you write and structure your document content. It is divided into two areas: a left sidebar showing the document tree, and a main editor area where you write content for the selected node. Changes save automatically as you work.

## The document tree

The left sidebar displays your document as a collapsible tree. The tree represents the full structure of your document and is where you manage nodes, adding, reordering, indenting, and deleting them.

At the top of the sidebar are two controls:

* **Document outline.** Toggle a full read-only outline of all sections, steps, and sub-steps in the main panel.
* **Add section.** Create a new top-level section at the bottom of the document.

## Node types

Documents use a three-level hierarchy. The levels are fixed. You cannot nest deeper than three levels.

| Level | Node type | Contains                 |
| ----- | --------- | ------------------------ |
| 1     | Section   | Steps and/or content     |
| 2     | Step      | Sub-steps and/or content |
| 3     | Sub-step  | Content only             |

Each node has a **title** and optional **rich text content**.

## Working with nodes

### Adding nodes

* Click **Add section** in the sidebar to add a new top-level section.
* To add a step inside a section, or a sub-step inside a step, use the add controls that appear when you hover over a node in the tree.

### Renaming nodes

Click into the title field at the top of the main editor area (below the node type label) and type the new name. The title saves automatically after a short pause.

You can also rename the document itself by clicking the document title in the top bar.

### Reordering nodes

Drag and drop nodes within the tree to reorder them. You can only reorder nodes within the same level. Drag a section to reorder among sections, a step to reorder among its siblings within the same section, and so on.

### Indenting and outdenting nodes

Use **indent** (demote) and **outdent** (promote) to change a node's level in the hierarchy.

* **Outdent (promote):** moves a step up to become a section, or a sub-step up to become a step. Right-click or use the node's context controls in the tree.
* **Indent (demote):** moves a section down to become a step inside the preceding section, or a step down to become a sub-step inside the preceding step.

<Warning>
  You cannot demote a section that has steps with sub-steps. Doing so would create a fourth level, which is not supported. Remove the sub-steps first.

  You cannot demote a step that already has sub-steps, for the same reason.
</Warning>

### Deleting nodes

Right-click a node in the tree and choose the delete option, or use the delete button that appears on hover. Deleting a node also deletes all of its children.

<Warning>
  Deletion is permanent and cannot be undone. A confirmation prompt appears before the node is removed.
</Warning>

## Writing content

Clicking a node in the tree opens it in the main editor area. The editor supports rich text formatting through a toolbar at the top of the content area.

**Available formatting:**

* **Bold** and **italic** text
* **Bullet lists**, **numbered lists**, and **checklists**
* **Images.** Upload via the image button in the toolbar, or paste an image directly into the editor

The editor also supports markdown shortcuts. For example, typing `**` around text applies bold.

## Auto-save

The editor saves continuously as you work. A status indicator in the top bar shows **Saving…** while a save is in progress and **Saved** once it completes. You do not need to manually save.

## Document outline view

Click **Document outline** at the top of the sidebar to switch the main panel to a read-only outline of the entire document. The outline displays all sections, steps, and sub-steps with their titles in a structured layout, useful for reviewing the overall structure before publishing.

Click **Document outline** again to return to the editing view.

## Image uploads

To add an image to a node's content:

* Click the image icon in the toolbar and select a file from your computer, or
* Paste an image directly into the editor content area.

Images are uploaded to DocInject and stored as part of the document.

## Video frames panel

If you created the document from a video, a frames panel is available in the editor. Click the camera icon in the toolbar to open it. The panel shows key frames extracted from your video, organized by timestamp. Click a frame to insert it as an image into the current node's content.
