-Digital research documents disseminated across many channels.
+Read the document "[What is a baseprint?](https://perm.pub/HKSI5NPzMFmgRlb4Vboi71OTKYo)"
+for a definition of _baseprint_. That document itself also serves as an example of a baseprint.
+Baseprints are used as digital objects (or editions) inside a digital succession.
+Visit [try.perm.pub](https://try.perm.pub/) to learn about digital successions of baseprints.
+For technical details and an illustration of a baseprint, see the [Technical Details page](tech.md).
