Follow these steps to setup and run ToolJet on macOS for development purposes. Open terminal and run the commands below. We recommend reading our guide on [architecture](/docs/contributing-guide/setup/architecture) of ToolJet before proceeding.
ToolJet uses a postgres database as the persistent storage for storing data related to users and apps. We do not plan to support other databases such as MySQL.
Create a `.env` file by copying `.env.example`. More information on the variables that can be set is given in the [environment variables reference](/docs/setup/env-vars)
```bash
cp .env.example .env
```
3. Populate the keys in the env file
:::info
`SECRET_KEY_BASE` requires a 64 byte key. (If you have `openssl` installed, run `openssl rand -hex 64` to create a 64 byte secure random key)
`LOCKBOX_MASTER_KEY` requires a 32 byte key. (Run `openssl rand -hex 32` to create a 32 byte secure random key)
