+### Migrating from v1
+
+#### What got changed?
+
+- Echo now uses `Engine` interface to abstract `HTTP` server implementation, allowing
+us to use HTTP servers beyond Go standard library, supports standard HTTP server and [FastHTTP](https://github.com/valyala/fasthttp).
+- Context, Request and Response as an interface, enabling adding your own functions and easy testing. [More...](https://github.com/labstack/echo/issues/146)
+- Moved API's for serving static files into middleware.
+    - `Echo#Index`
+    - `Echo#Favicon`
+    - `Echo#Static`
+    - `Echo#ServeDir`
+    - `Echo#ServeFile`
+- Dropped auto wrapping of handler and middleware to enforce compile time check.
+- Handler only accepts `Echo#Handler` interface.
+- Middleware only accepts `Echo#Middleware` interface.
+- `Echo#HandlerFunc` adapter to use of ordinary functions as handlers.
+- `Echo#MiddlewareFunc` adapter to use of ordinary functions as middleware.
+- Middleware is run before hitting the router, which doesn't require `Echo#Hook` API as
+it can be achieved via middleware.
+- Ability to define middleware at route level.
+
+#### How?
+
+##### v1 Handler
+
+```go
+func welcome(c *echo.Context) error {
+	return c.String(http.StatusOK, "Welcome!\n")
+}
+```
+
+##### v2 Handler
+
+```go
+func welcome(echo.HandlerFunc(c echo.Context) error {
+	return c.String(http.StatusOK, "Welcome!\n")
+})
+```
+
+##### v1 Middleware
+
+```go
+func welcome(c *echo.Context) error {
+	return c.String(http.StatusOK, "Welcome!\n")
+}
+```
+
+v2
+
+```go
+func welcome(echo.HandlerFunc(c echo.Context) error {
+	return c.String(http.StatusOK, "Welcome!\n")
+})
