 ### Text watermarking
 
-> Note : Text watermarking is not completed yet.
+```bash

+#### Allowed font identifiers 
+
+Currently the following font names are supported:
+- **Courier**:	`courier`, `courier_bold`, `courier_oblique`, `courier_bold_oblique`
+- **Helvetica**:	`helvetica`, `helvetica_bold`, `helvetica_oblique`, `helvetica_bold_oblique`
+- **Times Roman**:	`times`, `times_bold`, `times_italic`, `times_bold_italic`
 
 ### Additional notes
 
 - **Specifying Colors**: write them as 6 or 3 digit hexadecilal as used in CSS, without the #
-- Allowed font specifiers
-- Negaive offset will set content positioning from opposite side (right for offsetX and botom from offsetY)
-- Text with opacity is not supported at this moment. Instead, you can create a transperent background PNG image with your text and then use it for watermarking.
+
+- `--color`, `--font` and `--font-size` flag has no impact for Image watermarking
+- `--scale-*` and `--opacity` flag has no impact for Text watermarking
+- Negative offset will set content positioning from opposite side (right for offsetX and botom from offsetY)
+- Text with opacity is not supported at this moment. Instead, you can [create a transperent background PNG image](http://www.picturetopeople.org/text_generator/others/transparent/transparent-text-generator.html) with your text and then use it for watermarking.
