+Global tasks
+============
+
+This guide covers how to use poethepoet as a global task runner, for private user level tasks instead of shared project level tasks. Global tasks are available anywhere, and serve a similar purpose to shell aliases or scripts on the ``PATH`` — but as poe tasks.
+
+There are two steps required to make this work:
+
+1. Create a project somewhere central such as ``~/.poethepoet`` where you define tasks that you want to have globally accessible
+2. Configure an alias in your shell's startup script such as ``alias goe="poe -C ~/.poethepoet"``.
+
+The project at ``~/.poethepoet`` can be a regular poetry project including dependencies or just a file with tasks.
+
+You can choose any location to define the tasks, and whatever name you like for the global poe alias.
+
+.. warning::
+
+  For this to work Poe the Poet must be installed globally such as via pipx or homebrew.
+
+
+Shell completions for global tasks
+----------------------------------
+
+If you uze zsh or fish then the usual completion script should just work with your alias (as long as it was created with poethepoet >=0.28.0).
+
+However for bash you'll need to generate a new completion script for the alias specifying the alias and the path to you global tasks like so:
+
+.. code-block:: bash
+
+  # System bash
+  poe _bash_completion goe ~/.poethepoet > /etc/bash_completion.d/goe.bash-completion
+
+  # Homebrew bash
+  poe _bash_completion goe ~/.poethepoet > $(brew --prefix)/etc/bash_completion.d/goe.bash-completion
+
+.. note::
+
+  These examples assume your global poe alias is ``goe``, and your global tasks live at ``~/.poethepoet``.
+
+How to ensure installed bash completions are enabled may vary depending on your system.
