 # Ego2mix
 
 This Go library calls the Eco2mix API from RTE and returns data about the French electricity grid.
+
+## Usage
+
+```go
+package main
+
+import (
+	"fmt"
+
+	ego2mix "github.com/nmasse-itix/ego2mix"
+)
+
+func main() {
+	client := ego2mix.NewEco2mixClient("", nil)
+	records, err := client.FetchNationalRealTimeData(1) // we want only the last result
+	if err != nil {
+		panic(err)
+	}
+	fmt.Printf("Intensité carbone à %s en France: %d gCO2eq / kWh\n", records[0].DateHeure, records[0].TauxCo2)
+}
+```
