 \subsection{Configuration file}
 \par
 It's worth starting with the configuration file. This is a file in which the user can manually turn rules on and off or configure the rules settings. Below is one of the rules in the configuration file.
-

-\begin{center}
-\begin{tabular}{@{}l@{}}
- name: FILE\underline{ }IS\underline{ }TOO\underline{ }LONG\\ 
- \hspace{1cm}enabled: true\\
- \hspace{1cm}configuration:\\
- \hspace{2 cm}maxSize: '2000'\\
- \hspace{2 cm}ignoreFolders: ' '\\
-\end{tabular}
-\end{center}
-
+\\
+\begin{lstlisting}[caption={Part of configuration file.},
+label={lst:example1}, language=Kotlin]
+- name: DIKTAT_COMMON
+  configuration:
+    # put your package name here - it will be autofixed and checked
+    domainName: your.name.here
+- name: COMMENTED_OUT_CODE
+  enabled: true
+- name: HEADER_MISSING_OR_WRONG_COPYRIGHT
+  enabled: true
+  configuration:
+    isCopyrightMandatory: true
+    copyrightText: 'Copyright (c) Your Company Name Here. 2010-2020'
+    testDirs: test
+- name: FILE_IS_TOO_LONG
+  enabled: true
+  configuration:
+    maxSize: '2000'
+    ignoreFolders: ' '
+\end{lstlisting}
 Each rule in this file has 3 fields: name - the name of the rule, enabled - whether the rule is enabled or disabled (all rules are enabled by default), configuration - parameters for the rule. With the first two, everything is obvious. The third parameter is less obvious. The configuration is a set of "properties" to configure this rule. For example, for a rule "FILE\underline{ }IS\underline{ }TOO\underline{ }LONG", that checks the number of lines in a Kotlin file, the user can configure the maximum number of lines allowed in the file - by changing the "maxSize" in the configuration, or the user can specify paths to folders that do not need to be checked - by writing the path in "ignoreFolders". \\
