 ## Setting up the environment
 
-ToDo
+### Requirements
+
+You'll need to have the following tools installed on your machine:
+
+- [Node (>= v18.18)](https://nodejs.org/en/download/)
+- Yarn ([v1](https://classic.yarnpkg.com/en/docs/install/) or [v2+](https://yarnpkg.com/getting-started/install))
+- [Git](https://git-scm.com/downloads)
+
+### Setting up your local testing environment
+
+First, you'll need to clone this repository and install dependencies:
+
+```
+git clone https://github.com/buidlguidl/ctf.buidlguidl.com.git
+cd ctf.buidlguidl.com
+yarn install
+```
+
+Now you will run the following commands in separate terminals:
+
+1. Run a local blockchain:
+
+```
+yarn chain
+```
+
+2. Deploy the challenges contracts locally:
+
+```
+yarn deploy
+```
+
+3. Start Ponder (event indexer):
+
+```
+yarn ponder:dev
+```
+
+> Note: This just runs the ponder indexer locally, which is used to keep track of all the events happening in the blockchain.
+
+4. Start the frontend (NextJS app):
+
+```
+yarn start
+```
+
+Visit the CTF local website at: `http://localhost:3000`. Remember to switch to `hardhat` on `scaffold.config.ts`.
+
+
+> [!NOTE]
+> You can also test with the live data pointing to the Ponder live URL (update `NEXT_PUBLIC_PONDER_URL` env var)
