-You can read about the [MACI requirements here](https://maci.pse.dev/docs/quick-start/installation). To install MACI run the following commands:
+In order to run MACI polls, a coordinator is required to publish their MACI public key. You will need to generate a MACI keypair, and treat the private key just as your Ethereum private keys. Please store them in a safe place as you won't be able to finish a round if you lose access, or if compromised a bad actor could decrypt the vote and publish them online. You can generate a new key pair by running the following commands:
 
 ```bash
-git clone https://github.com/privacy-scaling-explorations/maci.git && \
-cd maci && \
-git checkout v2.4.0 && \
-pnpm i && \
-pnpm run build
+cd packages/coordinator

-> The circuits of MACI version ^2.0.0 are audited, and the zKeys have undergone a trusted setup ceremony.

-### Download .zkey files
+### Download the zero knowledge artifacts
 
 Download ceremony artifacts for production:
 
 ```bash
-pnpm download:ceremony-zkeys

 or the test keys for testnet only:
 
 ```bash
-pnpm download:test-zkeys

-Generate a new key pair and save it in a secure place.
+For the frontend to know what metadata has each Poll we need to generate and upload a JSON file that then is stored on-chain. The best way to do it is using the following command:

+1. Name of the round
+2. Brief description of the round
+3. Start time of the round, and how long will last the application and voting periods.

+This command will upload the JSON file to your configured vercel account and will print a link which you need to add in the Set the configuration file section.

 Once the voting time has ended, as a coordinator, first you need to merge signups and messages (votes). Head to **MACI** repository and run the merge command with the deployed poll:
 
 ```bash

 pnpm merge:[network] --poll [poll-id]
 ```

-> For version 1.2 you need to deploy a new MACI contract for a new round.

 Then the coordinator generates proofs for the message processing, and tally calculations. This allows to publish the poll results on-chain and then everyone can verify the results when the poll is over:
 
 ```bash
 pnpm run prove:[network] --poll [poll-id] \
     --coordinator-private-key [coordinator-maci-private-key] \

 ```
 
 > [!IMPORTANT]
-> We suggest including the --start-block flag, proving requires fetching all events from the smart contracts and by default starts from block zero, this would take a lot of time and is error-prone due to RPC provider limitations.

+Now it's time to submit the poll results on-chain so that everyone can verify the results:
 
-Once you have the `tally.json` file you can rename it (`tally-{pollId}.json`), upload it and add it as an environment variable `NEXT_PUBLIC_TALLY_URL` to show the results.
