+
+An opinionated plugin to select or create git worktree's and branches, and then open in a new window within the current tmux session.
+
+## Dependencies
+
+ - [fzf](https://github.com/junegunn/fzf)
+
+## Installation with Tmux Plugin Manager (recommended)
+
+Add plugin to the list of [TPM](https://github.com/tmux-plugins/tpm) plugins in your `.tmux.conf`:
+
+```tmux
+set -g @plugin 'NigelGreenway/tmux-git-workflow'
+```
+
+Hit <prefix> + I to fetch the plugin and source it.
+
+## Usage
+
+This is set to the key binding of `C-g` which will trigger a `display-popup` and ask for the worktree name and then the branch.
