-This tutorial requires the fuzzing feature available in Beta 1. To install the
-beta, following these steps:
-
-1. Run the following command to install the beta.
-
-   ```
-   $ go install golang.org/dl/go1.18beta1@latest
-   ```
-
-2. Run the following command to download updates.
-
-   ```
-   $ go1.18beta1 download
-   ```
-
-3. Run `go` commands using the beta instead of a released version of Go (if you
-   have one).
-
-   You can run commands with the beta either by using the beta name or by
-   aliasing the beta to another name.
-
-   - Using the beta name, you can run commands by invoking `go1.18beta1` instead
-     of `go`:
-
-     ```
-     $ go1.18beta1 version
-     ```
-
-   - By aliasing the beta name to another name, you can simplify the command:
-
-     ```
-     $ alias go=go1.18beta1
-     $ go version
-     ```
-
-   Commands in this tutorial will assume you have aliased the beta name.
