 ### Compute Function Specification
 
 You must implement the `AxiomComputeFn` on your input struct. There is only one trait function that you must implement:
+
 ```rust
 fn compute(
     api: &mut AxiomAPI,
     assigned_inputs: AccountAgeCircuitInput<AssignedValue<Fr>>,
 ) -> Vec<AxiomResult>
 ```
+
 where `AccountAgeCircuitInput` should be replaced with your derived circuit input struct.
 
 The `AxiomAPI` struct gives you access to subquery calling functions in addition to a `RlcCircuitBuilder` to specify your circuit. Your compute function should then return any values that you wish to pass on-chain in the `Vec<AxiomResult>` -- an `AxiomResult` is either an enum of either `HiLo<AssignedValue<Fr>>` or `AssignedValue<Fr>` (in which case it is converted to hi-lo for you).
 
 Here is an example:

 ```rust
 impl AxiomComputeFn for AccountAgeInput {

 ### Running The Circuit
 
 To run your circuit, create a `main` function call the `run_cli` function with your input struct as the generic parameter:
+
 ```rust
 fn main() {
     env_logger::init();
     run_cli::<AccountAgeInput>();
 }
 ```

 The `main` function will run a CLI that allows you to run mock proving, key generation, and proving of your circuit. The CLI has the following commands:

+Note that for the above example to work with the provied `data/account_age_input.json`, the `PROVIDER_URI` needs to be a JSON-RPC URI for Sepolia Testnet.
