\section{\class{wxRegKey}}\label{wxregkey}
-wxRegKey is a class representing the Windows Registry.
+wxRegKey is a class representing the Windows registry (it is only available
+under Windows). One can create, query and delete registry keys using this
+class.
+
+The Windows registry is easy to understand. There are five registry keys,
+namely:
+
+\begin{enumerate}\itemsep=0pt
+\item HKEY\_CLASSES\_ROOT (HKCR)
+\item HKEY\_CURRENT\_USER (HKCU)
+\item HKEY\_LOCAL\_MACHINE (HKLM)
+\item HKEY\_CURRENT\_CONFIG (HKCC)
+\item HKEY\_USERS (HKU)
+\end{enumerate}
+
+After creating a key, it can hold a value. The values can be:
+
+\begin{enumerate}\itemsep=0pt
+\item String Value
+\item Binary Value
+\item DWORD Value
+\item Multi String Value
+\item Expandable String Value
+\end{enumerate}
-One can Create, Query and Delete Registry Keys using this class.
