# Is there a way to change which LaTeX file is previewed? My project involves several documents

A project can only have one main file at present—it's the one which loads when you visit the document.

A simple way of compiling another file is to put:

```latex
\input{other-file.tex}
```

as the first line in the main file—before even the document class. This will cause us to compile that file instead, and LaTeX will ignore the rest of the "main" file.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://overleaf-pro.ayaka.space/latex/knowledge-base/098-is-there-a-way-to-change-which-latex-file-is-previewed-my-project-involves-several-documents.md?ask=<question>&goal=<endgoal>
```

`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.
