```python
def note_detail(request, note_id):
    note = Note.objects.get(pk=note_id)

    if request.method == 'POST':
        form = NoteForm(request.POST)
        if form.is_valid():
            title = form.cleaned_data['title']
            content = form.cleaned_data['content']
            note.title = title
            note.content = content
            note.save()
            return redirect('notes')
            
    return render(request, 'note_detail.html', {'note': note})
```

1. `if request.method == 'POST':`: This checks if the HTTP request method is POST, which is typically used for submitting form data;

2. `form = NoteForm(request.POST)`: This creates an instance of the `NoteForm` form class, using the data submitted in the POST request (`request.POST`);

3. `if form.is_valid():`: This checks if the form data is valid according to the form's validation rules;

4. `title = form.cleaned_data['title']`: This retrieves the cleaned (validated and processed) value of the 'title' field from the form;

5. `content = form.cleaned_data['content']`: Similarly, this retrieves the cleaned value of the 'content' field from the form;

6. `note.title = title` and `note.content = content`: These lines update the 'title' and 'content' fields of the `Note` object with the cleaned data obtained from the form;

7. `note.save()`: This saves the changes made to the `Note` object in the database;

8. `return redirect('notes')`: If everything is successful, the user is redirected to the 'notes' page.
