-## HTML Diff
-
-This is a diffing library that understands HTML. Best suited for cases when you want to show a diff of user-generated HTML.
-
-- The implementation is a port of JavaScript (https://github.com/alaorneto/htmldiffer, no license defined)
-- which is a port of CoffeeScript (https://github.com/tnwinc/htmldiff.js, MIT license)
-- which is a port of the original Ruby (https://github.com/myobie/htmldiff, MIT license)
-
-An enhancement was made so the code can also produce the diff of two texts (tags are treated like text).

 ## Diff3 Utils
 
 This is a library to find differences between two string tables, generate and apply patches, and perform 3-way merging between an original and two changed string tables. It contains similar functionality to the [GNU Diffutils](https://www.gnu.org/software/diffutils/manual/diffutils.html) tools.

-
-## Usage: HTML Diff
-
-**Diffing HTML**
-
-The following produces the diff of two example HTML snippets:
-
-```abap
-DATA:
-  lv_original TYPE string,
-  lv_modified TYPE string,
-  lv_diff     TYPE string,
-  li_htmldiff TYPE REF TO zif_htmldiff.
-
-lv_original = '\n'
-  && '    <p>First paragraph.</p>\n'
-  && '    <ul>\n'
-  && '        <li>Item A</li>\n'
-  && '        <li>Item B</li>\n'
-  && '        <li>Item C</li>\n'
-  && '    </ul>\n'
-  && '    <img src="previous.jpg">\n'
-  && '    <span>This is some interesting text.</span>\n'.
-
-lv_modified = '\n'
-  && '    <p>First paragraph.</p>\n'
-  && '    <ul>\n'
-  && '        <li>Item A</li>\n'
-  && '        <li>Item B</li>\n'
-  && '        <li>Item D</li>\n'
-  && '    </ul>\n'
-  && '    <img src="next.jpg">\n'
-  && '    <span>This is some new text.</span>\n'.
-
-REPLACE ALL OCCURRENCES OF '\n' IN lv_original WITH cl_abap_char_utilities=>newline.
-REPLACE ALL OCCURRENCES OF '\n' IN lv_modified WITH cl_abap_char_utilities=>newline.
-  
-CREATE OBJECT li_differ TYPE zcl_htmldiff.
-  
-lv_diff = li_htmldiff->htmldiff(
-  iv_before   = lv_original
-  iv_after    = lv_modified
-  iv_with_img = abap_false ).
-```
-
-Result:
-
-```html
-    <p>First paragraph.</p>
-    <ul>
-        <li>Item A</li>
-        <li>Item B</li>
-        <li>Item <del>C</del><ins>D</ins></li>
-    </ul>
-    <img src='previous.jpg'><img src='next.jpg'>
-    <span>This is some <del>interesting</del><ins>new</ins> text.</span>
-```
-
-By setting the image parameter to true, you can also mark changed images as deletions or insertions:
-
-```abap
-lv_diff = li_htmldiff->htmldiff(
-  iv_before   = lv_original
-  iv_after    = lv_modified
-  iv_with_img = abap_true ).
-```  
-
-Result:
-
-```html
-    <p>First paragraph.</p>
-    <ul>
-        <li>Item A</li>
-        <li>Item B</li>
-        <li>Item <del>C</del><ins>D</ins></li>
-    </ul>
-    <del><img src='previous.jpg'></del><ins><img src='next.jpg'></ins>
-    <span>This is some <del>interesting</del><ins>new</ins> text.</span>
-```
-
-There are a few other options you can set in the `constructor`:
-
-- `iv_inserts`: Show `<ins>` tags (default: on)
-- `iv_deletes`: Show `<del>` tags (default: on)
-- `iv_css_classes`: Add CSS classes to `<ins>` and `<del>` tags (default: off)
-- `iv_support_chinese`: Treat Chinese characters as individual words (default: off)
-
-Using CSS classes, the result will distinguish between inserts (class `diffins`), deletes (class `diffdel`), and updates (class `diffmod`).
-
-See the [test classes](https://github.com/Marc-Bernard-Tools/ABAP-Differ/blob/main/src/zcl_htmldiff.clas.testclasses.abap) for more examples.

-**Diffing Text**
-

-
-```abap
-lv_diff = li_htmldiff->textdiff(
-  iv_before = lv_original
-  iv_after  = lv_modified ).
-```  
-
-**Styling**
-
-Here's an examle for styling the insertions and deletions using CSS.
-
-```css
-/* CSS for <ins> and <del> tags */
-ins { background-color: #ddffdd; }
-ins img { border-color: #ddffdd; }
-
-del { background-color: #ffdddd; }
-del img { border-color: #ffdddd; }
-```
