\bfseries{\LARGE{top.sls}}

The \texttt{top.sls} file is used to map what SLS modules get loaded onto what minions via the state system.\\

Here is an example \texttt{top.sls} file which uses \texttt{pkg}, \texttt{file} and \texttt{service} states:

\begin{verbatim}
apache:
  pkg:
    - installed
    - version: 2.2.23
  service:
    - running
    - enable: True
/var/www/index.html: # ID declaration
  file:              # state declaration
    - managed        # function
    - source: salt://webserver/index.html
    - user: root
    - group: root
    - mode: 644
    - require:       # requisite declaration
      - pkg: apache  # requisite reference
\end{verbatim}


\bfseries{\LARGE{file}}

Manages files.
