# Tag Management

Tags are identifiers of DeHs and can help you quickly identify your DeHs.

You can add a tag to a DeH during the DeH creation. Alternatively, you can add a tag to a DeH on the Tags tab of the DeH details page. A maximum of 10 tags can be added to a DeH.

A tag consists of a tag key and a tag value. Table 1 lists the naming requirements for keys and values.
