 ## Versioning
 
-After publishing, you can publish new versions of datasets (Datasets contain a DOI, such as an Experiment, Simulation, or Mission) if you wish to update the files/data. A version number will be appended to the end of the citation, but the DOI will not change.
+If after publishing a dataset with a DOI you wish to make changes to the content of files, upload new and/or remove files, you can version the dataset. The version number will be appended to the end of the citation, but the DOI will not change, and it will always be possible for users to view the previous versions. 
 
-If you only need to update metadata, you can amend without creating a new version. Simply change the metadata in the **Curation Directory**, then select **Amend** after selecting **Prepare to Publish / Version / Amend** (See step 2).
