+## Versioning
+
+After publishing, you can publish new versions of datasets if you wish to update the files/data. A version number will be appended to the end of the citation.
+
+**Note:** If you only need to update metadata, you can amend the metadata 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).
+
+### 1. Make Changes in Curation Directory
+
+![](./imgs/guide-versioning-1a.png)
+
+Remove files from a dataset (Experiment, Simulation, Mission, or anything with a DOI) in the **Curation Directory** by removing their relationship to the dataset or the category/collection within the dataset.
+
+![](./imgs/guide-versioning-1b.png)
+
+Add new files by assigning them to a dataset or a category/collection within a dataset.
+
+For **Project Type Other**, new files do not need to be assigned to a specific dataset because entire project is one dataset. Make sure the new files are in the **Curation Directory** so they can be selected for the new version in step 2.
+
+### 2. Prepare to Version
+
+![](./imgs/guide-versioning-2a.png)
+
+Select **Prepare to Publish / Amend / Version** in the **Publication Preview** and you will be given the choice to publish new datasets to your project, amend metadata, or version existing published datasets. Select **Version** to continue.
+
+**Note:** If you only need to update metadata, select **Amend**.
+
+![](./imgs/guide-versioning-2b.png)
+
+Select each published dataset that has been updated and continue. You can version multiple datasets at once. Datasets that have not been published for the first time cannot be selected. 
+
+For **Project Type Other**, select each file to be included in the new version.
+
+### 3. Explain Changes & Publish
+
+![](./imgs/guide-versioning-3a.png)
+
+You will be asked to explain the changes made to this new version. This will help someone viewing your data to understand its history, so be thorough in your explanation.

+Once published, a viewer will be able to toggle between the versions.
