 Import phase 1 by deserializing a .ptau file: `semaphore-mtb-setup p1i <ceremony.ptau> <lastPhase1Contribution.ph1>`.
 
 To get a sample r1cs file from `semaphore-mtb`, checkout the [`semaphore-mtb` repository](https://github.com/worldcoin/semaphore-mtb.git) and run the following command:
 
 ```bash
-git clone https://github.com/worldcoin/semaphore-mtb.git && git checkout wip/mk/r1cs-export
+cd ..
+git clone https://github.com/worldcoin/semaphore-mtb.git

+./gnark-mbu r1cs --mode <insertion/deletion> --tree-depth=<TREE_DEPTH> --batch-size=<BATCH_SIZE> --output=demo_smtb.r1cs
+cd ..
 ```
 
 Move the file into the `semaphore-mtb-setup` directory:
 
 ```bash
-mv semaphore-mtb/demo_smtb.r1cs semaphore-mtb-setup/smtb.r1cs
+mv ./semaphore-mtb/demo_smtb.r1cs ./semaphore-mtb-setup/smtb.r1cs
