This is a modified beamerposter template based on the Gemini theme (see https://github.com/anishathalye/gemini) and the Beamer seagull color theme. Several colored boxes made with tcolorbox are also added.
This is a template and guide for preparing papers for Monthly Notices of the Royal Astronomical Society using the 'mnras' LaTeX package.
See the mnras_template.tex file (included and used by default when opening the template) for a simple template to help you get started.
The mnras_guide.tex file (also included) provides instructions for using the additional features in the document class. This is not a general guide on how to use LaTeX, and nor does it replace the journal's instructions to authors.
