My LaTeX template for math notes with stylized definitions, theorems and lemmas etc. from tcolorbox.
https://github.com/LazzzzyJack/math-notes-template
This is a simple latex template for taking notes. I am still working on improving the commands and environments. Any requests or features do let me know.
This template can be used to produce Lab Guides at Instituto Superior Técnico (IST) of Universidade de Lisboa (UL). The template may be suitable for other similar purposes just changing the logo.
