+
+Go package for app configuration. Supports chained configuration sources for multiple levels of defaults.
+Includes APIs for loading Linux style configuration files (name/value pairs) or INI files, map based properties,
+or easily create new configuration sources (e.g. load from database).
+
+Supports monitoring configuration sources for changes, hot loading properties, and notifying listeners of changes.
+
+## Usage
+
+```Go
+config := &cfg.Config{}
+defer config.Shutdown() // stops monitoring
+
+// load file via filespec string, os.File
+src, err := Config.NewSrcFileFromFilespec("./myfile.conf")
+if err != nil {
+    return err
+}
+// add src to top of chain, meaning first searched
+cfg.PrependSource(src)
+
+// fetch prop 'retries', default to 3 if not found
+val := config.Int("retries", 3)
+```
+
+See [example](./example_test.go) for more complete example, including listening for configuration changes.
+
+Config API parses the following data types:
+
+| type    | method | example property values |
+| ------- | ------ | -------- |
+| string  | Config.String  | test, "" |
+| int     | Config.Int     | -1, 77, 0  |
+| int64   | Config.Int64   | -9223372036854775, 372036854775808 |
+| float64 | Config.Float64 | -77.3456, 95642331.1 |
+| bool    | Config.Bool    | T,t,true,True,1,0,False,false,f,F |
+| time.Duration | Config.Duration | "10ms", "2 hours", "5 min" * |
+
+\* Units of measure supported: ms, sec, min, hour, day, week, year.
