# How to view scenario C1 Flow (YAML) in Scenario Builder?

When you need the logic of a section as **plain text** — without walking the canvas node by node — **Scenario Builder** can open **C1 Flow**: a YAML description of states, transitions, and translations. This is **view-only**: edits in the editor are not saved to the scenario.

## When you need this

- Share a section’s structure with a colleague or support.
- Read long state chains and branches more easily than on the canvas.
- Copy a YAML fragment for analysis outside the constructor.

## Before you start

- [x] You are signed in as an integrator or administrator.
- [x] **Scenario Builder** is open for the target bot.
- [x] **C1 Flow projection** is enabled for your instance (an administrator turns it on under **Settings → Feature Flags**). If the menu item is missing, contact your administrator.
- [x] The scenario is **published** (or saved on the server) when you need an up-to-date snapshot: YAML is built from the saved bot state, not from unsaved canvas edits.

---

## Open C1 Flow view

1. Open the target **section** in **Scenario Builder**.
2. On the top toolbar, click the **gear** button (**Settings** menu).
3. Choose **View C1 Flow (YAML)**.
4. The **C1 Flow** window opens with a text editor.

While data loads, you see **Loading projection...**.

## Using the window

| Element | Purpose |
|--------|---------|
| **File** | Projection YAML files: `bot.c1.yaml` (bot metadata) and `sections/…c1.yaml` (per section). |
| Editor | Text of the selected file; scrolling and syntax highlighting. Edits are **not saved**. |
| **Version hash** | Short snapshot id (useful when contacting support). |
| **Copy** | Copies the full current file to the clipboard. |

By default, the YAML for the **current section** is selected when available.

## If view is unavailable

| Symptom | What to do |
|--------|------------|
| **View C1 Flow (YAML)** is missing under **Settings** | Ask an administrator to enable C1 Flow projection on the instance. |
| Message that projection is unavailable | Same — setting is off or not applied on the instance. |
| Load error | Check connectivity; **publish** the scenario and try again. If it persists, contact support. |
| Empty file list | Save or publish the scenario, then open the view again. |

---

## Limitations

- **View only.** YAML changes in the window **do not** update the canvas or publish the scenario.
- The snapshot reflects the **saved** bot state; unsaved canvas edits are **not** included in YAML.
- C1 Flow is a **text view** of logic; not every canvas detail maps one-to-one to YAML.

To change the scenario, keep working on the canvas or use your usual publish flow. See [What is C1 Flow (YAML)?](/en/scenariobuilder/explanation/what-is-c1-flow-yaml.md) for more on the format.
