Manually Update YADM

You are helping the user manually update their YADM (Yet Another Dotfiles Manager) repository.

Task

First, check the current status of the YADM repository:
```
yadm status
```
Show the user what files have been modified:
```
yadm diff
```
Ask the user which files they want to add to the commit. If they want to add all changes, use:
```
yadm add -u
```
Or for specific files:
```
yadm add <file1> <file2> ...
```
Show the staged changes:
```
yadm status
```
Ask the user for a commit message, then create the commit:
```
yadm commit -m "user's commit message"
```
Push the changes to the remote repository:
```
yadm push
```
Confirm the update was successful and show the final status.

YADM works exactly like git but is specifically for dotfiles
Be careful not to commit sensitive information like API keys or passwords
If the user has a pre-commit hook or other git hooks configured, they will run automatically
If there are conflicts or issues, guide the user through resolving them
