Why are you using a verse environment if you don't want it to be indented?
Also, why are you using paragraph breaks, rather than line breaks?
Why not just this:
Code: Select all
\noindent For developers:
\begin{itemize}
\item how to write the source files,
\item how to test the machine executables.
\end{itemize}
For compiler: how to produce machine executables.\\
For hardware: how to execute the compiler output.\\
For the software users: how to use the resulting software.\\
If you want it to be set off horizontally, you could use something like \bigskip at the beginning and the end.
The itemize bullets will still be indented. If you don't want those indented either then load the
enumitem package, and use "\begin{itemize}[leftmargin=*]".
