-## Supported Go versions
+## Echo

-Latest version of Echo supports last four Go major [releases](https://go.dev/doc/devel/release) and might work with
-older versions.
+High performance, extensible, minimalist Go web framework.

-As of version 4.0.0, Echo is available as a [Go module](https://github.com/golang/go/wiki/Modules).
-Therefore a Go version capable of understanding /vN suffixed imports is required:
+* [Official website](https://echo.labstack.com)
+* [Quick start](https://echo.labstack.com/docs/quick-start)
+* [Middlewares](https://echo.labstack.com/docs/category/middleware)

-Any of these versions will allow you to import Echo as `github.com/labstack/echo/v4` which is the recommended
-way of using Echo going forward.
+Help and questions: [Github Discussions](https://github.com/labstack/echo/discussions)

-For older versions, please use the latest v3 tag.
