### Local bins
If your projects include dependencies with binaries, this ensures that they take precedence on your `$PATH` over globally installed ones.
For example, if you are using antigen, you would put the following in your `.zshrc`:
```shell
export NVM_PREFER_LOCAL_BINS=true
antigen bundle lukechilds/zsh-nvm
```
## Installation
### Using [Antigen](https://github.com/zsh-users/antigen)
