 9 | ### Step 1. Clone the repo
10 | ```bash
11 | git clone https://github.com/hussamkhatib/Real-time-collaborative-sandpack.git`
12 | ```
13 | ### Step 2. Set up environment variables
14 | 
15 | Copy the `.env.local.example` file in this directory to `.env.local` (which will be ignored by Git):
16 | 
17 | ```bash
18 | cp .env.local.example .env.local
19 | ```
20 | 
21 | Then set each variable on `.env.local`:
22 | 
23 | ### Step 3. Run in development mode 
24 | ```bash
25 | yarn install
26 | yarn dev
27 | ```
