- Similarly to the mvn plugin
- Without this fix, the shell crashes in some cases

+# zsh-interactive-cd
+
+This plugin adds a fish-like interactive tab completion for the `cd` command.
+
+To use it, add `zsh-interactive-cd` to the plugins array of your zshrc file:
+```zsh
+plugins=(... zsh-interactive-cd)
+```
+
+![demo](https://user-images.githubusercontent.com/1441704/74360670-cb202900-4dc5-11ea-9734-f60caf726e85.gif)
+
+## Usage
+
+Press tab for completion as usual, it'll launch fzf automatically. Check fzf’s [readme](https://github.com/junegunn/fzf#search-syntax) for more search syntax usage.
+
+## Requirements
+
+This plugin requires [fzf](https://github.com/junegunn/fzf). Install it by following
+its [installation instructions](https://github.com/junegunn/fzf#installation).
