    1. **Enter Your Text**:
    - Type or paste the text you want to annotate in the text area provided.
    
    2. **Submit Your Text**:
    - Click the "Submit Text" button to process your input. This will split your text into individual words.

    3. **Annotate the Words**:
    - For each word, you can provide a label (e.g., "Emotion", "Priority", "Verb").
    - Choose a color for each label using the color picker.

    4. **Generate Annotated Text**:
    - Once you have labeled and colored the words you want to annotate, click the "Generate Annotated Text" button.
    - The annotated text will be displayed, showing your labels and chosen colors.

    5. **Take a Screenshot**:
    - To use the annotated text, take a screenshot of the displayed text.

    6. **Adjust Text Width** (Optional):
    - If you want to adjust the width of the sentences for a better screenshot, minimize or resize your browser window accordingly before taking the screenshot.
