+## Hacking PSE E2E setup instructions on Optimism Sepolia
+
+### Mint top hat and create first hat
+You'll need to mint a top hat and then create your first hat. The hat id of your first hat is the one we'll be assigning to vote participants. Learn more about hats at [the hats documentation](https://docs.hatsprotocol.xyz/)
+1. Go to [the hats contract on op scan](https://sepolia-optimism.etherscan.io/address/0x3bc1a0ad72417f2d411118085256fc53cbddd137#writeContract) and connect your wallet
+2. Call `mintTopHat` - You can take inspriation from [this tx](https://sepolia-optimism.etherscan.io/tx/0x57d6562494335b9ae640e97c4e3fb7f3d80a0141352652a42da6c2d9ed662804)
+3. Call `createHat` - Add the id of the `HatCreated` log from the `mintTopHat` transaction as the admin (`_admin (uint256)`) for this call. Add your own address for `_eligibility (address)` & `_toggle (address)`. You can take inspiration from [this tx](https://sepolia-optimism.etherscan.io/tx/0x45bc3410ceb95cd5c760dd11ffbc99cbd8f5c3b488240612788fcf3674124edb)
+4. Take the hat id from the logs of `HatCreated`, add this hat id the the `.env` files in `backend`, `contracts` and `interface`
+
+
+### Deploy Semaphore contracts gated by Hats
+
+1. Add a rpc url, deployer private key, op scan api key, hats address, and hat id to a `.env` file in `packages/contracts`. The hats address for optimism sepolia is `0x3bc1A0Ad72417f2d411118085256fC53CBdDd137`. That hats id is the value you got in the transaction logs when calling `createHat`
+2. `cd packages/contracts`
+3. Deploy contracts:
+```bash
+# Load the variables in the .env file
+source .env
+
+# To deploy and verify the contract
+forge script --chain sepolia script/Hackathon.s.sol:DeploySemaphore_AndSetGate --rpc-url $SEPOLIA_RPC_URL --etherscan-api-key $ETHERSCAN_API_KEY --broadcast --verify -vvvv
+```
+4. Add the semahore address to `.env` in `interface`
+
+
+### Deploy MACI contracts
+1. Follow installation instructions for MACI if this is your first time running a maci poll https://maci.pse.dev/docs/quick-start/installation. After installing the required dependencies to your machine, setup the maci monorepo: 
+```bash
+# install dependencies and run pnpm build
+git clone https://github.com/privacy-scaling-explorations/maci.git && \
+cd maci && \
+pnpm i && \
+pnpm run build
+```
+
+2. You won't need to compile new circuits, but you will need to download the zkeys
+```bash
+# download zkeys
+pnpm download-zkeys:test
+```
+
+3. Generate and safely store a coordinator key pair https://maci.pse.dev/docs/quick-start/deployment#coordinator-key
+```bash
+# generate a coordinator key pair - save this for later
+cd packages/cli && \
+node build/ts/index.js genMaciKeyPair
+```
+
+4. `cp deploy-config-example.json deploy-config.json`
+    1. go to the `optimism_sepolia` json object in `deploy-config.json`
+    2. set the following values to ensure maci works with the semaphore gatekeeper you deployed. Set your desired poll duration as well
+    ```json
+    "optimism_sepolia": {
+      "FreeForAllGatekeeper": {
+        "deploy": false
+      },
+      "SemaphoreGatekeeper": {
+        "deploy": true,
+        "semaphoreContract": "THE SEMAPHORE ADDRESS YOU DEPLOYED",
+        "groupId": 1
+      },
+      "MACI": {
+        "stateTreeDepth": 10,
+        "gatekeeper": "SemaphoreGatekeeper"
+      },
+      "Poll": {
+        "pollDuration": 3600, 
+        "coordinatorPubkey": "YOUR MACI PUBLIC KEY GENERATED FROM genMaciKeyPair",
+        "useQuadraticVoting": false
+      }
+    }
+    ```
+
+5. `cp default-deployed-contracts.json deployed-contracts.json`
+Fill the `.env` file with the appropriate data (you will find an example in the .env.example file):
+    - your mnemonic
+    - an RPC key
+
+5. `pnpm deploy:optimism-sepolia --incremental`
+6. In this repo, add the maci address to `NEXT_PUBLIC_MACI_ADDRESS` in the interface `.env`
+
+### Deploy the subgraph
+In the same MACI repo, deploy the subgraph
+1. `cd apps/subgraph`
+2. Add the maci address and the block it was deployed in to `apps/subgraph/config/network.json`
+3. `pnpm run build`
+4. if you need to deploy again, remember to increment the version label each time
+```bash
+graph deploy test-maci-vote \                                                                                                                               
+  --version-label v0.0.1 \
+  --node https://subgraphs.alchemy.com/api/subgraphs/deploy \
+  --deploy-key YOUR_DEPLOY_KEY \
+  --ipfs https://ipfs.satsuma.xyz/
+```
+
+### Start frontend + backend
+From the root of this repo
+1. `pnpm install && pnpm build`
+2. `pnpm dev:server`
+3. `pnpm dev:interface`
+
 ## Supported Networks
 
 All networks EAS is deployed to are supported. If a network is not supported, you can follow the EAS documentation to deploy the contracts to the network.
