These are the techniques that come up across every kind of project. Learn them once and they apply to images, video, and everything you build on top. * [Inpainting and outpainting](/docs/essentials/inpainting-and-outpainting.md): change part of a frame, or extend beyond its edges * [Layers](/docs/essentials/layers.md): isolate and select parts of an image to work on * [Models](/docs/essentials/models.md): train a model on your own material and reuse it *** If you have any trouble or have any questions, feel free to reach out.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://morphic.com/docs/essentials.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
