+# Custom Package Continued
+
+Let's use our new `mystrings` package in `hellogo`
+
+Modify hellogo's `main.go` file:
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"{REMOTE}/{USERNAME}/mystrings"
+)
+
+func main() {
+	fmt.Println(mystrings.Reverse("hello world"))
+}
+```
+
+Don't forget to replace {REMOTE} and {USERNAME} with the values you used before. Then edit hellogo's `go.mod` file to contain the following:
+
+```go
+module example.com/username/hellogo
+
+go 1.20
+
+replace example.com/username/mystrings v0.0.0 => ../mystrings
+
+require (
+	example.com/username/mystrings v0.0.0
+)
+```
+
+Now build and run the new program:
+
+```bash
+go build
+./hellogo
+```
