+\subsection{Math-Commands}
+All these have to be executed in the math environment.
+\begin{itemize}
+    \item \verb|\R| Prints $\R$. Same goes for \verb|\C| printing $\C$, etc.
+    \item \verb|\floor|\{\textit{math}\} Round down symbol, e.g. $\floor{n}$
+    \item \verb|\ceil|\{\textit{math}\} Round up symbol, e.g. $\ceil{n}$
+    \item \verb|\hastoeq| or \verb|\mbeq| Has to equal symbol (non-standard), $\hastoeq$
+    \item \verb|\Leftrightarrowequiv| Equivalence transformation symbol, $\Leftrightarrowequiv$.
+    \item \verb|\Rightarrowequiv| Equivalence transformation symbol, $\Rightarrowequiv$.
+    \item \verb|\Leftarrowequiv| Equivalence transformation symbol, $\Leftarrowequiv$.
+    \item \verb|\defAs| Define as, i.e. $\defAs$
+    \item \verb|\defEquiv| Define as, but with a two-sided implication instead of equality, i.e. $\defEquiv$
+    \item \verb|\defImplies| Define as, but with one-sided implication, i.e. $\defImplies$
+    \item \verb|\divides| Divider or divides symbol, e.g. $a \divides b$
+    \item \verb|\lcm| Least common multiple, $\lcm$

+\subsection{CS-Commands}
+These commands have to be executed outside the math environment.
+\begin{itemize}
+    \item \verb|\timecomplexity| Prints the word time complexity with a coloured box.
+    \item \verb|\tc| Shorthand for \verb|\tct|. Deprecated
+    \item \verb|\tct| Time complexity in \tct{}-notation (average case)

+    \item \verb|\tcl| Time complexity in \tcl{}-notation (best case / lower bound)

 \subsection{Style}
 General styling commands. All other commands, except these ones require at least \texttt{most} to be the selected \textit{scope}
