+# About Settings
+Various settings exist in the build of alteriso.  
+The user can change some of these settings with arguments, but some of them only can be changed by editing the configuration file.  
+Also, channel developers may wish to prohibit some values from being changed.  
+This section explain the changeable values and the order in which the configuration files are loaded.  
+
+# Syntax
+All the configuration file is written in bash scripts. Also, all settings are read by the `source` command.  
+
+# Values can be set
+The full list of changeable values are in `default.conf`.  
+It is recommended that copy the comments with it when you copy the configuration into a separate file and make changes.  
+
+# List of files to be read
+They are read in order from the top. Please replace with architecture and channel name when read the `<architecture>` and `<channel_name>`  
+If the same variable is set, it is overwritten each time the configuration file is read.
