+## Versioning
+
+This repository does not use semantic versioning. MAJOR version tracks which Echo version should be used. MINOR version
+tracks API changes (possibly backwards incompatible) and PATCH version is incremented for fixes.
+
+> **Always add at least one integration test in your project.**
+
+For Echo `v5` use `v5.x.y` releases.
+Minimal needed Echo versions:
+
+* `v5.x.y` needs Echo `v5.0.0+`, use `go get github.com/labstack/echo-contrib@v5`
+* `v0.18.0` needs Echo `v4.15.0+`, use `go get github.com/labstack/echo-contrib@v0.18.0`
+
+For `v0.x.y` releases the code is located in `v4` branch.
