### Writing the package
|
||||
|
||||
Now that you've initialized your workspace it's time to write a simple package. Package name usually starts with a
|
||||
domain name (as in Go) followed with a descriptive name. In this example we will use my Github domain name and call our
|
||||
package `echo` because it will print a single line to stdout.

domain name (as in Go) followed with a descriptive name. In this example we reuse the Cloud Run example and create a

package from it.

mkdir -p cue.mod/pkg/github.com/tjovicic/echo

mkdir -p cue.mod/pkg/github.com/tjovicic/gcpcloudrun
