+To build the main circuits of MACI, run the following command (`-c` postfix for c++ witness gen, and `-wasm` postfix for WASM witness gen only):
 
 ```
-circom --r1cs --sym --wasm --output ./build circom/test/processMessages_10-2-1-2_test.circom

For more information on the parameters and how to configure them, please refer to the individual circuit documentation within this page. Also, within the [configure-circomkit](https://maci.pse.dev/docs/installation#configure-circomkit) section of the `installation` page, you'll see how you can update the config file with new params.

+To compile a single circuit, you can run:
+
+```
+pnpm circom:build $CIRCUIT_NAME
