# Build Page Walkthrough
Once your Dimensions project is set up, you'll land in the **Build** tab — the central workspace for scripting, reviewing, and managing your survey. This guide introduces the key panels and features you'll use day-to-day.
***
### Script Panel
The left side of the screen displays your survey script, split into two tabs:
* **Metadata** — defines your questions, answer lists, and variable types.
* **Routing** — controls survey flow and logic.
You can use the **split screen** feature to view or edit metadata and routing scripts side-by-side — either vertically or horizontally.
***
### Quotas Panel
At the top, you'll find the **Quotas** panel. It starts empty and populates once quotas are generated through the AI agent.
***
### Design Files & Agent
The right side of the screen gives you access to two key panels:
* **Design File** — displays your uploaded questionnaire as a constant reference while you work.
* **AI Assistant** — chat-based agent that helps you program questions, quotas, and logic.
***
### Edit History
View a timeline of all file changes and versions, so you can track what was modified and when.
#### Saving Checkpoints
You can manually save a checkpoint at any point to bookmark your progress. Give it a descriptive name and click **Save Checkpoint**.
***
### Save, Sync & Test
When you're ready to push your work back to your Dimensions project directory:
1. Click **Save and Sync** at the top to write your code changes back to the project directory.
2. Click **Test** to launch the Unicorn app and preview your survey build directly.
