 Loro draws inspiration from the innovative work of the following projects and individuals:
 
-- [Ink & Switch](https://inkandswitch.com/): The principles of Local-first Software have greatly influenced this project. The [Peritext](https://www.inkandswitch.com/peritext/) project has also shaped our approach to rich text CRDTs.
 - [Diamond-types](https://github.com/josephg/diamond-types): The [Event Graph Walker (Eg-walker)](https://loro.dev/docs/advanced/event_graph_walker) algorithm from @josephg has been adapted to reduce the computation and space usage of CRDTs.
 - [Automerge](https://github.com/automerge/automerge): Their use of columnar encoding for CRDTs has informed our strategies for efficient data encoding.
 - [Yjs](https://github.com/yjs/yjs): We have incorporated a similar algorithm for effectively merging collaborative editing operations, thanks to their pioneering work.
