Software Used

A list of open-source software and components used to build this documentation.

Our goal in building new and comprehensive documentation for XLT was to use open-source components. Below is a list of frameworks, fonts, and their respective licenses used to create this documentation.

Framework

Hugo

The documentation is built with Hugo, which boasts being “one of the most popular open-source static site generators” and, like XLT, is licensed under the Apache 2.0 license.

Theme: Docsy

Hugo can be used with predefined or custom themes. We use the Docsy theme as a base and add our CI flavor to it. Docsy is a theme specifically designed for technical documentation sets and is also licensed under the Apache 2.0 license.

Fonts

Roboto and Ubuntu Mono

The fonts used in this documentation are Roboto and Ubuntu Mono, both originally part of the Google Fonts project but hosted on our own servers. Roboto is licensed under the Apache 2.0 license, while Ubuntu Mono uses the Ubuntu Font License.
