 ## Instructions for each participant
 
-TODO
+First, set up a Linux machine and install Rust and Cargo following instructions [here](https://www.rust-lang.org).
+
+Download and compile the required source code:
+
+```bash
+git clone https://github.com/kobigurk/phase2-bn254.git --branch semaphore-setup && \
+cd phase2-bn254/phase2 && \
+cargo build --release
+```
+
+Next, get the `circuit<n>.params` file from the coordinator.
+
+In the `phase2` directory, run:
+
+```bash
+cargo run --release --bin contribute circom<n>.params circom<n+1>.params <random entropy>
+```
+
+Send the `circom<n+1>.params` file to the coordinator.
+
+## Test run
+
+1. Cloned `phase2-bn254` and switched to the `ppot_fix` branch
+
+2. Ran `b2sum -b challenge` on challenge 0023
