+# Official Sentry Echo Handler for Sentry-go SDK
+
+**go.dev:** https://pkg.go.dev/github.com/getsentry/sentry-go/echo
+
+**Example:** https://github.com/getsentry/sentry-go/tree/master/_examples/echo
+
+## Installation
+
+```sh
+go get github.com/getsentry/sentry-go/echo
+```
+
+```go
+import (
+    "fmt"
+    "net/http"
+
+    "github.com/getsentry/sentry-go"
+    sentryecho "github.com/getsentry/sentry-go/echo"
+    "github.com/labstack/echo/v4"
+	"github.com/labstack/echo/v4/middleware"
+)
+
+// To initialize Sentry's handler, you need to initialize Sentry itself beforehand
+if err := sentry.Init(sentry.ClientOptions{
+    Dsn: "your-public-dsn",
+}); err != nil {
+    fmt.Printf("Sentry initialization failed: %v\n", err)
+}
+
+// Then create your app
+app := echo.New()
+
+app.Use(middleware.Logger())
+app.Use(middleware.Recover())
+
+// Once it's done, you can attach the handler as one of your middleware
+app.Use(sentryecho.New(sentryecho.Options{}))
+
+// Set up routes
+app.GET("/", func(ctx echo.Context) error {
+    return ctx.String(http.StatusOK, "Hello, World!")
+})
+
+// And run it
+app.Logger.Fatal(app.Start(":3000"))
+```
+
+## Configuration
+
+`sentryecho` accepts a struct of `Options` that allows you to configure how the handler will behave.
+
+Currently it respects 3 options:
+
+```go
+// Repanic configures whether Sentry should repanic after recovery, in most cases it should be set to true,
+// as echo includes its own Recover middleware that handles http responses.
+Repanic bool
+// WaitForDelivery configures whether you want to block the request before moving forward with the response.
+// Because Echo's `Recover` handler doesn't restart the application,
+// it's safe to either skip this option or set it to `false`.
+WaitForDelivery bool
+// Timeout for the event delivery requests.
+Timeout time.Duration
+```
+
+## Usage
+
+`sentryecho` attaches an instance of `*sentry.Hub` (https://pkg.go.dev/github.com/getsentry/sentry-go#Hub) to the `echo.Context`, which makes it available throughout the rest of the request's lifetime.
+You can access it by using the `sentryecho.GetHubFromContext()` method on the context itself in any of your proceeding middleware and routes.
+And it should be used instead of the global `sentry.CaptureMessage`, `sentry.CaptureException`, or any other calls, as it keeps the separation of data between the requests.
+
+**Keep in mind that `*sentry.Hub` won't be available in middleware attached before to `sentryecho`!**
+
+```go
+app := echo.New()
+
+app.Use(middleware.Logger())
+app.Use(middleware.Recover())
+
+app.Use(sentryecho.New(sentryecho.Options{
+	Repanic: true,
+}))
+
+app.Use(func(next echo.HandlerFunc) echo.HandlerFunc {
+	return func(ctx echo.Context) error {
+		if hub := sentryecho.GetHubFromContext(ctx); hub != nil {
+			hub.Scope().SetTag("someRandomTag", "maybeYouNeedIt")
+		}
+		return next(ctx)
+	}
+})
+
+app.GET("/", func(ctx echo.Context) error {
+	if hub := sentryecho.GetHubFromContext(ctx); hub != nil {
+		hub.WithScope(func(scope *sentry.Scope) {
+			scope.SetExtra("unwantedQuery", "someQueryDataMaybe")
+			hub.CaptureMessage("User provided unwanted query string, but we recovered just fine")
+		})
+	}
+	return ctx.String(http.StatusOK, "Hello, World!")
+})
+
+app.GET("/foo", func(ctx echo.Context) error {
+	// sentryecho handler will catch it just fine. Also, because we attached "someRandomTag"
+	// in the middleware before, it will be sent through as well
+	panic("y tho")
+})
+
+app.Logger.Fatal(app.Start(":3000"))
+```
+
+### Accessing Request in `BeforeSend` callback
+
+```go
+sentry.Init(sentry.ClientOptions{
+    Dsn: "your-public-dsn",
+    BeforeSend: func(event *sentry.Event, hint *sentry.EventHint) *sentry.Event {
+        if hint.Context != nil {
+            if req, ok := hint.Context.Value(sentry.RequestContextKey).(*http.Request); ok {
+                // You have access to the original Request here
+            }
+        }
+
+        return event
+    },
+})
+```
