An introduction to authoring with LaTeX for the sciences. The text assumes no prior knowledge of LaTeX. It is intended for students and professionals who wants a brief introduction as a basis for further self-learning. It should be sufficient for writing any document that is based on a template or specific class.

v.2: Added appendix on how to install LaTeX locally on a personal computer. Minor typos in v.1 corrected. Adjusted for Overleaf v2 upgrade.
