 ### A few useful inbuilt oracles
 
-- [`compute_selector`](https://github.com/AztecProtocol/aztec-packages/blob/master/yarn-project/aztec-nr/aztec/src/selector.nr) - Computes the selector of a function. This is useful for when you want to call a function from within a circuit, but don't have an interface at hand and don't want to hardcode the selector in hex.
 - [`debug_log`](https://github.com/AztecProtocol/aztec-packages/blob/master/yarn-project/aztec-nr/aztec/src/oracle/debug_log.nr) - Provides a couple of debug functions that can be used to log information to the console.
 - [`auth_witness`](https://github.com/AztecProtocol/aztec-packages/blob/master/yarn-project/aztec-nr/authwit/src/auth_witness.nr) - Provides a way to fetch the authentication witness for a given address. This is useful when building account contracts to support approve-like functionality.
 - [`get_l1_to_l2_message`](https://github.com/AztecProtocol/aztec-packages/blob/master/yarn-project/aztec-nr/aztec/src/oracle/get_l1_to_l2_message.nr) - Useful for application that receive messages from L1 to be consumed on L2, such as token bridges or other cross-chain applications.
