 If these env vars are not present, then depending on configuration, stubs will be used for the endpoints or the program will crash

+## Usage
+```go
+package main
+
+import (
+	"os"
+
+	"github.com/gin-contrib/sessions"
+	"github.com/gin-contrib/sessions/memstore"
+	"github.com/gin-gonic/gin"
+	"github.com/janishutz/oidclogin"
+)
+
+func main() {
+	r := gin.Default()
+
+	// TODO: Better secret
+	store := memstore.NewStore([]byte("secret"))
+	r.Use(sessions.Sessions("jhid", store))
+
+	oidclogin.Configure(r, os.Getenv("APP_BASE_URL"), "/account", false)
+	r.LoadHTMLGlob("public/*")
+
+	r.GET("/account", oidclogin.EnsureLogin(false), func(ctx *gin.Context) {
+		ctx.HTML(200, "main.tmpl", gin.H{})
+	})
+
+	r.Run()
+}
+```
+This example further needs the environment variable `APP_BASE_URL` set to something like `https://app.example.org`.
+Further, you should create a template file called `main.tmpl` and also copy over the template files in the `public` directory here and edit them.
