+# About
+
+Listed here is a collection of cheatsheet by topic. Those cheatsheets do not
+explain the topics in depth, but rather serve as quick lookup documents.
+Therefore, the course material provided by the lecturer should still be studied
+and understood. Not everything that is tested at the mid-terms or final exams is
+covered and the Author does not guarantee that the cheatsheets are free of
+errors.
+
+* [Number bases](./cheatsheet_number_bases.pdf)
+* [Sequences and Series](./cheatsheet_sequence_series.pdf)
+* [Modular Arithmetic](./cheatsheet_modular_arithmetic.pdf)
+* [Trigonometry](./cheatsheet_trigonometry.pdf)
+* [Graphs of Functions & Kinematics](./cheatsheet_graphs_functions_kinematics.pdf)
+* [Trigonometrical Functions & Identities](./cheatsheet_trigonometrical_functions_identities.pdf)
+* [Exponential & Logarithm Functions](./cheatsheet_exponential_logarithm_funcions.pdf)
+* [Gradients of Curves & Differentiation](./cheatsheet_gradients_curves_differentiation.pdf)
+* [Vectors](./cheatsheet_vectors.pdf)
+* [Matrices](./cheatsheet_matrices.pdf)
+* [Statistics](./cheatsheet_statistics.pdf)
+* [Probability & Combinatorics](./cheatsheet_probability_combinatorics.pdf)
+
+# Building
+
+_NOTE_: This step is only necessary if you chose to modify the base docments.
+
+The base documents are written in [AsciiDoc](https://asciidoc.org/) and can be
+found in the `src/` directory.
+
+The following dependencies must be installed (Ubuntu):
+
+```console
+$ apt install -y ruby-dev wkhtmltopdf
+$ gem install asciidoctor
+$ chmod +x build.sh
+```
+
+To build the documents (PDF version):
+
+```console
+$ ./build.sh pdf
+```
+
+Optionally, for the HTML version:
+
+```console
+$ ./build.sh html
+```
+
+and for the PNG version:
+
+```console
+$ ./build.sh png
+```
+
+The generated output can be deleted with `./build.sh clean`.
+
+# Disclaimer
+
+The Presented Documents ("cheatsheets") by the Author ("Fabio Lama") are
+summaries of specific topics. The term "cheatsheet" implies that the Presented
+Documents are intended to be used as learning aids or as references for
+practicing and does not imply that the Presented Documents should be used for
+inappropriate practices during exams such as cheating or other offences.
+
+The Presented Documents are heavily based on the learning material provided by
+the University of London, respectively the VLeBooks Collection database in the
+Online Library, especially on the books:
+
+* _Foundation maths (Harlow: Pearson, 2016) 6th edition by Croft, A. and R. Davison_
+* _Precalculus with Limits (January 1, 2017) 4th edition by Ron Larson_
+
+The Presented Documents may incorporate direct or indirect definitions,
+examples, descriptions, graphs, sentences and/or other content used in those
+provided materials. **At no point does the Author present the work or ideas
+incorporated in the Presented Documents as their own.**
