+If the vanity URL is causing issues in your project due to a dependency pulling Mergo - it isn't a direct dependency in your project - it is recommended to use [replace](https://github.com/golang/go/wiki/Modules#when-should-i-use-the-replace-directive) to pin the version to the last one with the old import URL:

+If you need to override pointers, so the source pointer's value is assigned to the destination's pointer, you must use `WithoutDereference`:
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"dario.cat/mergo"
+)
+
+type Foo struct {

+		A: &second,
+		B: 1,
+	}
+
+	mergo.Merge(&dest, src, mergo.WithOverride, mergo.WithoutDereference)
+}
+```

 Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
