 These are instructions for making a new Remotion project and composition.

 ## Scaffold a project
 
 If a project already exists, skip this.
 Ensure Node.js and Git is installed, and the current folder is appropriate for starting a new project.
 
-Scaffold one using:
+Inspect the current folder, including hidden files, before choosing where to scaffold.
+
+### Empty folder
+
+If it is empty, or contains only disposable operating-system metadata such as `.DS_Store`, create the project directly in the current folder.
+Remove only those disposable metadata files first, since `create-video` rejects non-empty folders.
+Do not treat all hidden files as disposable: files such as `.env` and directories such as `.git` are meaningful contents.
+
+Scaffold in existing folder:
 
 ```bash
-npx create-video@latest --yes --blank --no-tailwind my-video
-cd my-video
+npx create-video@latest --yes --blank --no-tailwind .
 npm i
 ```
 
+### Non-empty folder
+
+If the current folder contains meaningful contents and no project already exists, scaffold into a new subfolder.
 Replace `my-video` with a suitable project name.
 
+```bash
+npx create-video@latest --yes --blank --no-tailwind my-video
+cd my-video
+npm i
+```
+
 ## Designing a video
 
 Keep the scaffold and add React Markup.
-Follow [Remotion React Markup Best Practices](../remotion-markup/SKILL.md) and [Video Layout Rules](video-layout.md) for video-first layout and text sizing guidance.

+
+Before writing the root that registers `<Composition>` or `<Still>` elements,
+follow Compositions and stills.
+
+## Is this a timeline of clips?
+
+If the video arranges multiple video or audio clips on a timeline, follow
+Video editing before writing the
+timeline. Give every clip that should be edited independently its own authored
+JSX node.
 
 ## Is this a multi-scene video?
 
-If this is a video with multiple subsequence videos, follow guidance at [Multi-scene videos](../remotion-markup/multi-scene-video.md).
+If this is a video with multiple subsequent scenes, follow guidance at Multi-scene videos.
 
 ## Interactivity Best Practices
 
-By structuring the React Markup following [Remotion Interactivity Best Practices](../remotion-interactivity/SKILL.md), you allow the user to make edits in the Studio which write back to code.

 ## TailwindCSS
 
 If Tailwind is requested, see [tailwind.md](tailwind.md) for using TailwindCSS in Remotion.
 
-## Open the preview
-
-After creating or updating the video, start the preview server by default:
-
-```bash
-npx remotion studio --no-open
-```
-
-This will start a long-running process and print the server URL for the preview.  
-If the server is already started, it will print the URL.
-Open the exact URL in the Codex in-app browser. If no browser tool is available yet, use `tool_search` for the in-app browser control tool, then navigate to the local URL.
-You can visit a specific composition by navigating to `/[composition-id]`, for example `http://localhost:3000/MapAnimation`.
-
-## Render the video
-
-Only render if the user explicitly asks for it.
-
-```
-npx remotion render
-```
-
-For more options, see [Rendering](../remotion-render/SKILL.md).
-
 ## Follow-up
 
 The video creation process has finished.
-For follow-up prompts, use [Remotion Best Practices](../remotion-best-practices/SKILL.md)
