 ## Acknowledgments
 
 `nvm.fish` was established in 2016 by [**@jorgebucaran**](https://github.com/jorgebucaran) as the go-to Node.js version manager for Fish. It was inspired by the original [**nvm.sh**](https://github.com/nvm-sh/nvm) created by [**@creationix**](https://github.com/creationix) and [**@ljharb**](https://github.com/ljharb). To use the original nvm in Fish, consider [**@FabioAntunes/fish-nvm**](https://github.com/FabioAntunes/fish-nvm) or [**@derekstavis/plugin-nvm**](https://github.com/derekstavis/plugin-nvm). We appreciate all of our contributors! ❤️
