+	app.Usage = "Use provided environment to update configuration ini"
+	app.Description = `As a helper to allow docker users to update the forgejo configuration
+	through the environment, this command allows environment variables to
+	be mapped to values in the ini.
+
+	Environment variables of the form "FORGEJO__SECTION_NAME__KEY_NAME"
+	will be mapped to the ini section "[section_name]" and the key
+	"KEY_NAME" with the value as provided.
+
+	Environment variables of the form "FORGEJO__SECTION_NAME__KEY_NAME__FILE"
+	will be mapped to the ini section "[section_name]" and the key
+	"KEY_NAME" with the value loaded from the specified file.
+
+	Environment variables are usually restricted to a reduced character
+	set "0-9A-Z_" - in order to allow the setting of sections with
+	characters outside of that set, they should be escaped as following:
+	"_0X2E_" for ".". The entire section and key names can be escaped as
+	a UTF8 byte string if necessary. E.g. to configure:
+
+		"""
+		...
+		[log.console]
+		COLORIZE=false
+		STDERR=true
+		...
+		"""
+
+	You would set the environment variables: "FORGEJO__LOG_0x2E_CONSOLE__COLORIZE=false"
+	and "FORGEJO__LOG_0x2E_CONSOLE__STDERR=false". Other examples can be found
+	on the configuration cheat sheet.`
