+## How to use
+
+1. Define a config structure, like below:
+
+```go
+type RestfulConf struct {
+	Host         string        `json:",default=0.0.0.0"`
+	Port         int
+	LogMode      string        `json:",options=[file,console]"`
+	Verbose      bool          `json:",optional"`
+	MaxConns     int           `json:",default=10000"`
+	MaxBytes     int64         `json:",default=1048576"`
+	Timeout      time.Duration `json:",default=3s"`
+	CpuThreshold int64         `json:",default=900,range=[0:1000]"`
+}
+```
+
+2. Write the yaml, toml or json config file:
+
+- yaml example
+
+```yaml
+# most fields are optional or have default values
+Port: 8080
+LogMode: console
+# you can use env settings
+MaxBytes: ${MAX_BYTES}
+```
+
+- toml example
+
+```toml
+# most fields are optional or have default values
+Port = 8_080
+LogMode = "console"
+# you can use env settings
+MaxBytes = "${MAX_BYTES}"
+```
+
+3. Load the config from a file:
+
+```go
+// exit on error
+var config RestfulConf
+conf.MustLoad(configFile, &config)
+
+// or handle the error on your own
+var config RestfulConf
+if err := conf.Load(configFile, &config); err != nil {
+  log.Fatal(err)
+}
+
+// enable reading from environments
+var config RestfulConf
+conf.MustLoad(configFile, &config, conf.UseEnv())
+```
