+## Setup/Usage Tips - MUTN CLI
+Most information relevant to the usage of MUTN can be viewed with `mutn help`, in [the man page](https://raw.githubusercontent.com/rwinkhart/MUTN/main/docs/man), and in the demo animation from the README.
+
+Because of this, this wiki page will focus on initial setup as well as some tips that may not be immediately obvious.
+
+### Initial Setup
+libmutton operates on a client-server model, and thus sync support requires you to have access to your own server (whether it be a physical home server or a cloud rental) with remote access via SSH.
+
+For security reasons, libmutton deliberately does not support password-based SSH authentication; you must use key-based authentication to connect to your server (password-protected keys are also supported). You are responsible for setting up SSH connectivity on your own.
+
+The libmutton server software is shipped as its own dedicated binary and must be installed on the server and configured with `libmuttonserver init`.
+
+Once this has been done, you may proceed with the client setup:
+    1. Install MUTN
+    2. Run `mutn init` and follow the prompts
+    3. If you already have entries on the server, sync them using `mutn sync`
+    4. Optionally, shell completions (Bash, ZSH, and PowerShell 7+) can be [enabled with your shell's respective method](https://github.com/rwinkhart/MUTN/blob/main/wiki/MUTN/completions.md)
+
+### Tips
+#### Operating on Passwords
+Any action that operates on the password attached to an entry (copying, editing, adding a new password-focused entry) does not require the user to specify the `password` or `-pw` options. In all cases, `password` is the assumed target when no other option is specified.
+
+#### Granular Help
+Argument-specific help can be obtained by running `mutn <argument>` without an entry name or any options. For example, `mutn edit` will display help for the `edit` argument.
