+`gpt-disk-rs` is a collection of three libraries related to [GPT](https://en.wikipedia.org/wiki/GUID_Partition_Table) (GUID Partition Table) disk data. The crates are no-std by default, have minimal dependencies, and include a lot of documentation. I'm hoping they'll be a suitable base for any project that wants to read or write GPT data.
+
+* [`uguid`](https://crates.io/crates/uguid): GUID data type.
+* [`gpt_disk_types`](https://crates.io/crates/gpt_disk_types): all the GPT types defined by the UEFI specification
+* [`gpt_disk_io`](https://crates.io/crates/gpt_disk_io): types for reading and writing GPT data to an abstract block IO device.
