With deltangle you can do three things:

1. Store a text file. You will get a unique hash that will allow anyone to download the file.
2. Update a text file. You will get a unique hash that will allow anyone to download the new version.
3. Control the published version of a text file. You will get a unique hash that will allow anyone to download the version of the file that you want.

Deltangle updates files by storing the difference in a new bundle, so it minimizes the number of transactions required to be stored.

In addition, it uses MAIA, which allows you to create a unique address for an updatable text file.
