-You can obtain the package files by running LaTeX over the file `textualicomma.ins`:

-For compiling the documentation, run **LuaLaTeX** twice over the docstrip source file `textualicomma.dtx`:
+### Installation
+Extract the *package* file first:
+
+  1. Run LaTeX over the file `textualicomma.ins`
+  2. Move the resulting `.sty` file to `TEXMF/tex/latex/textualicomma/`
+
+Then, you can compile the *documentation* yourself by executing
+
+    lualatex textualicomma-doc.dtx
+    makeindex -s gind.ist textualicomma-doc.idx
+    makeindex -s gglo.ist -o textualicomma-doc.gls textualicomma-doc.glo
+    lualatex textualicomma-doc.dtx
+    lualatex textualicomma-doc.dtx
+    
+
+or just use the precompiled documentation shipped with the source files.  
+In both cases, copy the files `textualicomma-doc.pdf` and `README.md` to `TEXMF/doc/latex/textualicomma/`.

+    \section{Introduction}
+    Using the comma as decimal separator in ordinary \LaTeX\ has always been proble\-matic: since the comma is treated as punctuation,\TeX\ adds some space after it. \\
+    The solution was defining an \enquote*{intelligent} comma recognizing whether it's used as decimal separator or punctuation character.
+    
+    \medskip
+    The common package implementing this solution is \sty{icomma} by Walter Schmidt~\cite{icomma}.
+    However, some fonts, e.g. Source Serif Pro, don't provide any math support. \\
+    Although there are fonts looking very similar to Source Serif and providing math support (like Utopia and its ‘clones’ Fourier and Erewhon), more or less obvious differences are visible (compare \enquote*{$,$} to~\enquote*{,} at high magnifications). The only solution solving this \enquote*{problem} is escaping to text mode.
+    
+    
+    
+    \section{The \sty{textualicomma} package}
+    \subsection{\sty{textualicomma}'s behaviour}
+    \sty{textualicomma} makes some changes and additions to \sty{icomma}'s code in order to provide automated escaping to text mode.
+    The behaviour remains the same:
+    \begin{itemize}
+        \item
+            The comma is treated as decimal separator if it is directly followed by a number.
+            Thus, a number is to be entered as, for instance, \\
+            "3,142"
+        \item
+            whereas mathematical expressions like $(x\text{,}\,y)$ are to be written with a space after the comma: \\
+            \verb*|(x, y)|
+    \end{itemize}
+
+    Also, the period is redefined so that it adapts to the used font.
+    This feature might be useful with \LaTeX\ \cls{beamer}'s sans-serif math.
+    
+    
+    \subsection{Package options}
+    By default, the font used for typesetting the comma is the current roman text font. This behavior can be modified by using package options:
+    
+    \medskip\leavevmode%
+    \DescribeOption{sffamily}%
+    Passing the \opt{sffamily} option to \sty{textualicomma} results in the comma character being taken from the current sans serif text font
+    
+    \medskip\leavevmode%
+    \DescribeOption{ttfamily}%
+    Passing the \opt{ttfamily} option to \sty{textualicomma} results in the comma character being taken from the current mono-spaced text font
+    
+    
+    \bigskip
+    \DescribeMacro{\textualicommafont}
+    Both options change the used font family \textit{for the whole document}.
+    Changes \emph{inside} the document can be made using the "\textualicommafont" command: \\[\smallskipamount]
+    "\textualicommafont{\rmfamily}" \qquad\rightarrow~~ roman comma in math mode \\
+    "\textualicommafont{\sffamily}" \qquad\rightarrow~~ sans-serif comma in math mode \\
+    "\textualicommafont{\ttfamily}" \qquad\rightarrow~~ monospaced comma in math mode
+    
+    
+    
+    \section{Bugs and problems}
+    Generally, since the comma is made ‘active’, problems are not unlikely.
+    
+    \medskip
+    For example, when using the ‘intelligent comma’ together with the \sty{dcolumn} package, a comma to be \textit{printed} as the decimal separator in a column of type "D" is to be specified as "{\mathord\mathcomma}", rather than "{,}", since the latter leads to an error. For example:
+    \begin{center}
+        \verb|\begin{tabular}{... D{,}{\mathord\mathcomma}{2} ...}|
+    \end{center}
+
+    Note that specifying the comma as the related input character works as usual.
