\subsubsection{Maintainers}
We consider the author of each commit that changed a community profile document
as a maintainer of the document.
For each community profile document in a project,
We consider the author of each commit that changed a community profile file
as a maintainer of the documentation.
For each profile document in a project,
we got all the commits on it and counted the number of different maintainers (\ie commit authors) of the document.
Table~\ref{fig:main_matner} presents the distribution of maintainers for each type of documentation in the studied projectors.
Overall,
community profile documentation was usually maintained by a relatively small group of developers.
Specifically,
the number of maintainers of \LIC, \CON, \COD and \TMP
the numbers of maintainers of the \LIC, \CON, \COD and \TMP documentation
are 1.31 (median: 1), 2.52 (median: 1), 1.27 (median: 1), and 1.79 (median: 1), respectively.
Exceptionally,
\RDM files are maintained by more developers than other documentation;
the average number of maintainers is 4.84 (median: 3).
the average number of its maintainers is 4.84 (median: 3).
This is might be explained by the same reasons for the high update frequency of \RDM files
as shown in Section~\ref{interval}.
