Using fontspec to configure variable fonts can clutter a document's preamble with a lot of setup code. In this step, we show how to create a simple package to contain fontspec’s configuration code—simplifying the document preamble and making it easier to make further font changes.

## How to create and use a simple LaTeX package

Follow these steps to create a simple LaTeX package for the fontspec configuration code we have created for this tutorial.

1. Select the **New File** icon (![Overleaf icon representing adding a file](/files/HJNN59c59UNhVEzgUq96)) to create a new project file. Give it the name `myfontsettings.sty` and select **Create**.

![Image showing Overleaf's Add Files modal window](/files/QHpevu5i1kYpW4ZnbJjS)

3. Paste the fontspec configuration code into the file `myfontsettings.sty`. Here, we are using fontspec configuration code for Noto Serif, Noto Sans and Roboto Mono added during the variable fonts tutorial. You must modify the fontspec settings if you use different variable fonts.

```latex
% myfontsettings.sty
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{myfontsettings}[2024/06/13 v1.0 My custom font settings]

% This simple package contains your fontspec configuration
% It keeps your document's preamble clean and tidy

% Load fontspec package
\RequirePackage{fontspec}

% Set the main text font for the document
\setmainfont{NotoSerif-VariableFont-wdth-wght.ttf}[
Weight=400,
ItalicFont=NotoSerif-Italic-VariableFont-wdth-wght.ttf,
FontFace = {b}{n}{Font =NotoSerif-VariableFont-wdth-wght.ttf,Weight=600},
FontFace = {b}{it}{Font =NotoSerif-Italic-VariableFont-wdth-wght.ttf,Weight=600}
]

% Document family sans serif font
\setsansfont{NotoSans-VariableFont-wdth-wght.ttf}[
Weight=400,
ItalicFont=NotoSans-Italic-VariableFont-wdth-wght.ttf,
FontFace = {b}{n}{Font = NotoSans-VariableFont-wdth-wght.ttf,Weight=600},
FontFace = {b}{it}{Font = NotoSans-Italic-VariableFont-wdth-wght.ttf,Weight=600}
]

% Document family monospaced font
\setmonofont{RobotoMono-VariableFont-wght.ttf}[
NFSSFamily=RobotoMono,
Weight=300,
ItalicFont=RobotoMono-Italic-VariableFont-wght.ttf,
FontFace = {b}{n}{Font =RobotoMono-VariableFont-wght.ttf,Weight=550},
FontFace = {b}{it}{Font = RobotoMono-Italic-VariableFont-wght.ttf, Weight=550}
]

\endinput
```

5. To use this package, add the line `\usepackage{myfontsetting}` to your document preamble.

## 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/in-depth-articles/44-step-8-how-to-create-a-simple-latex-package-to-configure-your-variable-fonts.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.
