To create a JSON Web Token (JWT) in Go, you can use a popular library called `jwt-go`. Here's a step-by-step guide to create a JWT token using this library:

1. First, make sure you have Go installed on your system. If you don't, follow the instructions on the official Go website: https://golang.org/doc/install

2. Next, get the `jwt-go` library by running the following command in your terminal:
```
go get github.com/dgrijalva/jwt-go
```

3. Create a new Go file, such as `main.go`, and import the necessary packages:

```go
package main

import (
	"fmt"
	"time"

	"github.com/dgrijalva/jwt-go"
)
```

4. Now, create a function to generate the JWT token:

```go
func createToken(secretKey string) (string, error) {
	// Define the token claims (payload)
	claims := &jwt.StandardClaims{
		ExpiresAt: time.Now().Add(24 * time.Hour).Unix(),
		Issuer:    "MyApp",
	}

	// Create a new token with the claims and signing method
	token := jwt.NewWithClaims(jwt.SigningMethodHS256, claims)

	// Sign the token with the secret key
	signedToken, err := token.SignedString([]byte(secretKey))
	if err != nil {
		return "", err
	}

	return signedToken, nil
}
```

5. Finally, use the `createToken` function in the `main` function to generate a JWT token and print it:

```go
func main() {
	secretKey := "your-secret-key"

	token, err := createToken(secretKey)
	if err != nil {
		fmt.Println("Error creating token:", err)
		return
	}

	fmt.Println("Generated JWT token:", token)
}
```

Make sure to replace `your-secret-key` with your own secret key. This key is used to sign the token and will be required to verify the token later.

Now, when you run the `main.go` file with `go run main.go`, it will generate a JWT token and print it to the console.
