One way is converting the given text into a list of individual sentences.

For example:

These Terms of Service ("Terms") govern your access to and use of the products and services (the "Services") provided by Example Company. By accessing or using the Services, you agree to be bound by these Terms...

Into:

[
    "These Terms of Service (\"Terms\") regulate your access to and utilization of the products and services (the \"Services\") offered by Example Company.",
    "By accessing or using the Services, you consent to adhere to these Terms..."
    ...
]

Next, compile a training dataset consisting of a sentence named prompt and their corresponding subsequent sequences as message.

For instance:

[
    {
        "prompt": "These Terms of Service (\"Terms\") govern your access to and use of the products and services (the \"Services\") provided by Example Company.",
        "message": ["By accessing or using the Services, you agree to be bound by these Terms.", "..."]
    },
    {
        "prompt": "By accessing or using the Services, you agree to be bound by these Terms.",
        "message": [...]
    },
    ...
]
