+.SH ENVIRONMENT VARIABLES
+\fInmcli\fP's behavior is affected by the following environment variables.
+.IP "LC_ALL" 13
+If set to a non-empty string value, override the values of all the other
+internationalization variables.
+.IP "LC_MESSAGES" 13
+Determines the locale to be used for internationalised messages.
+.IP "LANG" 13
+Provides a default value for the internationalization variables that are unset
+or null.
+
+.RE
+Notes about localization:
+.br
+Be aware that \fInmcli\fP is localized and that's why the output depends on 
+your environment. It's important to realize that especially when you parse the
+output.
+.br
+Call \fInmcli\fP as \fBLC_ALL=C nmcli\fP to be sure the locale is
+set to "C" while executing in a script.
+
+\fBLC_ALL\fP, \fBLC_MESSAGES\fP, \fBLANG\fP variables specify the LC_MESSAGES
+locale category (in that order), which determines the language that \fInmcli\fP
+uses for messages.  The "C" locale is used if none of these variables are set,
+and this locale uses English messages.
+
 .SH EXIT STATUS
 \fInmcli\fP exits with status 0 if it succeeds, a value greater than 0 is returned if errors occur.
