+# Experimental features
+
+ZoKrates supports some experimental features.
+
+## Nova
+
+ZoKrates supports the `nova` proof system using the `bellperson` backend. Nova is accessed with the subcommand `nova`.
+
+### API
+
+To use Nova, programs must have the following signature, for any types `State` and `StepInput`:
+
+```
+def main(public State state, private StepInput step_input) -> State
+```
+
+Then, using Nova lets the user prove many steps of this program, given an initial state.
+
+For example:
+
+```
+{{#include ../../../zokrates_cli/examples/book/nova_step.zok}}
+```
+
+We compile this program using the Pallas curve:
+
+```bash
+zokrates compile -i sum.zok --curve pallas
+```
+
+Then we can prove three iterations as follows:
+
+```bash
+echo "\"0\"" > init.json
+echo "[\"1\", \"7\", \"42\"]" > steps.json
+zokrates nova prove
+```
+
+The proof created at `proof.json` proves the statement `0 + 1 + 7 + 42 == 50`.
+
+### Limitations
+
+- The step circuit must be compiled with `--curve pallas`
+- The resulting recursive proof cannot currently be verified on the EVM
+- The public parameters are currently computed for each proof
