+Config file support
+===================
+
+Config files are supported by most subcommands of ``pkgdev`` from any of three
+locations. Listed in order of increasing precedence these include the
+following:
+
+- system config -- /etc/pkgdev/pkgdev.conf
+- user config -- ~/.config/pkgdev/pkgdev.conf
+- custom config -- specified via the --config option
+
+Any settings from a config file with higher precedence will override matching
+settings from a config file with a lower precedence, e.g. user settings
+override system settings. Note that command line options override any matching
+config file setting.
+
+In terms of file structure, basic INI formatting is required and allows
+creating a default section (DEFAULT) for system-wide settings or repo-specific
+sections. The INI key-value pairs directly relate to the available
+long-options supported by the various prefixed by the subcommand name and their
+related values. To find all possible configuration options, run:
+``pkgdev {subcommand} --help``. See the following examples for config settings:
+
+- Run ``pkgcheck scan`` before committing and asks for confirmation (instead of
+  aborting) when creating commits with QA errors::
+
+    [DEFAULT]
+    commit.scan = true
+    commit.ask = true
+
+- Allow pushing commits with QA errors, but only for the 'gentoo' repository::
+
+    [gentoo]
+    push.ask = true
+
+- When committing, stage all files in current working directory (note that this
+  option doesn't expect value, therefore no value is defined post equal sign)::
+
+    [DEFAULT]
+    commit.all =
+
+- All previous config settings combined::
+
+    [DEFAULT]
+    commit.scan = true
+    commit.ask = true
+    commit.all =
+
+    [gentoo]
+    push.ask =
