See https://github.com/o1-labs/mina-rust/pull/1173. Goal: move as much as possible to the website. Clean issues if the doc is closing some (e.g. RPC endpoints). - [ ] Section "Add New RPC endpoints" ([here](https://github.com/tizoc/openmina/blob/b1a204dfc3444129af8d3d6eb84e66fc9d00af2a/docs/handover/adding-rpc-endpoints.md) - add to doc
