<p>This flow is composed of a standard chatbot with the <strong>Chat Input</strong>, <strong>Prompt</strong>, <strong>OpenAI</strong>, and <strong>Chat Output</strong> components, but it also incorporates a <strong>File</strong> component, which loads a file from your local machine. <strong>Parse Data</strong> is used to convert the data from <strong>File</strong> into the <strong>Prompt</strong> component as <code>{Document}</code>. The <strong>Prompt</strong> component is instructed to answer questions based on the contents of <code>{Document}</code>. This gives the <strong>OpenAI</strong> component context it would not otherwise have access to.</p>
