+
+A collection of schematic diagrams of lakes for use in LaTeX documents. Diagrams include representations of material budgets, fluxes, and connectivity arrangements.
+
+## Usage
+
+Call diagram commands in your document by setting `tikz-lake-fig.sty` as an input (e.g. `\usepackage{tikz-lake-fig}`). Each command takes a single argument specifiying the scale of the diagram (optionally a second argument for fill color):
+
+```latex
+\documentclass{standalone}
+\usepackage{tikz-lake-fig}
+
+\begin{document}
+	
+\secondarywireframe[1]
+	
+\end{document}
+```
