 ConvertAPI helps in converting various file formats. Creating PDF and Images from various sources like Word, Excel, Powerpoint, images, web pages or raw HTML codes. Merge, Encrypt, Split, Repair and Decrypt PDF files and many other file manipulations. You can integrate it into your application in just a few minutes and use it easily.
 
 The ConvertAPI-Go library makes it easier to use the Convert API from your Go projects without having to build your own API calls.

 This is the bare-minimum to convert a file using the ConvertAPI client, but you can do a great deal more with the ConvertAPI Go library.
-Take special note that you should replace `your-api-secret` with the secret you obtained in item two of the pre-requisites.
+Take special note that you should replace `api-token` with the token you obtained in item two of the pre-requisites.

+
+### Conversion Without Temporarily Storing Files on the ConvertAPI File Server
+By design, the ConvertAPI library uses a temporary file server to store files.
+A temporary file server is useful for conversion chaining and generally improves performance.
+However, the [Vanilla Go Example](examples/direct/main.go) demonstrates how to efficiently convert files without using the ConvertAPI file server.
+
+In this example, both the request and response use the `multipart` content type. This approach allows you to convert multiple files or return conversion results as multiple files.
+Using `multipart` is much more efficient compared to JSON with base64 encoding.
