NOTE: if a directory is found in both the allowed and disallowed lists, the disallowed list
takes preference, _i.e._ the .env file will never be sourced.
### ZSH_DOTENV_RECURSIVE, ZSH_DOTENV_ROOT
Set `ZSH_DOTENV_RECURSIVE=true` in your zshrc file to enable recursive search for the `ZSH_DOTENV_FILE` up to
`ZSH_DOTENV_ROOT` (default `$HOME`) and source from `$ZSH_DOTENV_ROOT` to `$PWD`.
```zsh
# in ~/.zshrc, before Oh My Zsh is sourced:
ZSH_DOTENV_RECURSIVE=true
ZSH_DOTENV_ROOT=/path/to/root
```
## Version Control
**It's strongly recommended to add `.env` file to `.gitignore`**, because usually it contains sensitive information such as your credentials, secret keys, passwords etc. You don't want to commit this file, it's supposed to be local only.
