+# MarkdownTextBlock
+
+MarkdownTextBlock is a evolution of the existing MarkdownTextBlock in the community toolkit. This new implementation uses the popular [Markdig](https://github.com/xoofx/markdig) library for parsing. This solves some long standing bugs and feature gaps in our existing implementation.
+
+## Templated Controls
+
+The Toolkit is built with templated controls. This provides developers a flexible way to restyle components
+easily while still inheriting the general functionality a control provides. The examples below show
+how a component can use a default style and then get overridden by the end developer.

+
+# COMMENTS
+
+Comments can be added in Markdown, and they won't be rendered to the screen.
+
+To create a comment, enclose in XML style comment tags:
+
+><\!-- Comments are now Implemented -->
+
+There is a Comment below this line.
+<!-- Comments are now Implemented -->
+
+&nbsp;
+
+# PARAGRAPHS
+
+Paragraphs are delimited by a blank line.  Simply starting text on a new line won't create a new paragraph; It will remain on the same line in the final, rendered version as the previous line.  You need an extra, blank line to start a new paragraph.  This is especially important when dealing with quotes and, to a lesser degree, lists.
+
+You can also add non-paragraph line breaks by ending a line with two spaces.  The difference is subtle:
+
+Paragraph 1, Line 1
+Paragraph 1, Line 2
+
+Paragraph 2
+

+
+# FONT FORMATTING
+### Italics
+
+Text can be displayed in an italic font by surrounding a word or words with either single asterisks (\*) or single underscores (\_).
+
+For example:
+
+>This sentence includes \*italic text\*.
+
+is displayed as:
+
+>This sentence includes *italic text*.
+
+
+### Bold
+
+Text can be displayed in a bold font by surrounding a word or words with either double asterisks (\*) or double underscores (\_).
+
+For example:
+
+>This sentence includes \*\*bold text\*\*.
+
+is displayed as:
+
+>This sentence includes **bold text**.
+
+### Bold & Italics
+
+Text can be displayed in a bold font by surrounding a word or words with either triple asterisks (\*) or triple underscores (\_).
+
+For example:
+
+>This sentence includes \*\*\*bold & italic text\*\*\*.
+
+is displayed as:
+
+>This sentence includes ***bold & italic text***.
+
+### Strikethrough
+
+Text can be displayed in a strikethrough font by surrounding a word or words with double tildes (~~).  For example:
+
+>This sentence includes ~ ~strikethrough text~ ~
+
+>*(but with no spaces between the tildes; escape sequences [see far below] appear not to work with tildes, so I can't demonstrate the exact usage).*
+
+is displayed as:
+
+>This sentence includes ~~strikethrough text~~.
+
+### Superscript
+
+Text can be displayed in a superscript font by preceding it with a caret ( ^ ).
+
+>This sentence includes super^ script
+
+>*(but with no spaces after the caret; Like strikethrough, the superscript syntax doesn't play nicely with escape sequences).*
+
+is displayed as:
+
+>This sentence includes super^script.
+
+Superscripts can even be nested: just^like^this .
+
+However, note that the superscript font will be reset by a space.  To get around this, you can enclose the text in the superscript with parentheses.  The parentheses won't be displayed in the comment, and everything inside of them will be superscripted, regardless of spaces:
+
+>This sentence^ (has a superscript with multiple words)
+
+>*Once again, with no space after the caret.*
+
+is displayed as
+
+>This sentence^(has a superscript with multiple words)
+
+### Subscript
+
+Text can be displayed in a subscript font by preceding it with a caret ( <sub></sub> ).
+
+>This sentence includes \<sub>sub\</sub> script
+
+>This sentence includes <sub>sub</sub>script.
+
+### Headers
+
+Markdown supports 6 levels of headers (some of which don't actually display as headers in reddit):
+
+# Header 1
+
+## Header 2
+
+### Header 3
+
+#### Header 4
+
+##### Header 5
+
+###### Header 6
+
+...which can be created in a couple of different ways.  Level 1 and 2 headers can be created by adding a line of equals signs (=) or dashes (\-), respectively, underneath the header text.
+
+However, *all* types of headers can be created with a second method.  Simply prepend a number of hashes (#) corresponding to the header level you want, so:
+
+>\# Header 1
+
+>\#\# Header 2
+
+>\#\#\# Header 3
+
+>\#\#\#\# Header 4
+
+>\#\#\#\#\# Header 5
+
+>\#\#\#\#\#\# Header 6
+
+results in:
+
+># Header 1
+
+>## Header 2
+
+>### Header 3
+
+>#### Header 4
+
+>##### Header 5
+
+>###### Header 6
+
+Note: you can add hashes after the header text to balance out how the source code looks without affecting what is displayed. So:
+
+>\#\# Header 2 ##
+
+also produces:
+
+>## Header 2 ##
+
+
+*****
+# LISTS
+
+Markdown supports two types of lists: ordered and unordered.
+
+### Unordered Lists
+
+Prepend each element in the list with either a plus (+), dash (-), or asterisk (*) plus a space.  Line openers can be mixed.  So
+
+>\* Item 1
+
+>\+ Item 2
+
+>\- Item 3
+
+results in
+
+>* Item 1
+>+ Item 2
+>- Item 3
+
+
+
+### Ordered Lists
+
+Ordered lists work roughly the same way, but you prepend each item in the list with a number plus a period (.) plus a space.  The number will increment by 1 starting from the number from the number of the first list item. So
+
+>7\. Item 1
+
+>2\. Item 2
+
+>5\. Item 3
+
+results in
+
+>7. Item 1
+>2. Item 2
+>5. Item 3
+
+Also, you can nest lists, like so:
+
+1. Ordered list item 1
+
+2. * Bullet 1 in list item 2
+    * Bullet 2 in list item 2
+
+3. List item 3
+
+Note: If your list items consist of multiple paragraphs, you can force each new paragraph to remain in the previous list item by indenting it by one tab or four spaces.  So
+
+>\* This item has multiple paragraphs.
+>
+>(*four spaces here*)This is the second paragraph
+>
+>\* Item 2
+
+results in:
+
+>* This item has multiple paragraphs.
+>
+>    This is the second paragraph
+>* Item 2
+
+
+### Task List
+You can also use the GitHub style task list. The syntax is the following:
+
+- [ ] Task 1
+- [x] Task 2
+- [ ] Task 3
+
+
+Notice how the spaces in my source were stripped out?  What if you need to preserve formatting?  That brings us to:
+
+*****
+
+# CODE BLOCKS AND INLINE CODE
+
+Inline code is easy.  Simply surround any text with backticks (\`), **not to be confused with apostrophes (')**.  Anything between the backticks will be rendered in a fixed-width font, and none of the formatting syntax we're exploring will be applied.  So
+
+>Here is some `` ` ``inline code with \*\*formatting\*\*`` ` ``
+
+is displayed as:
+
+>Here is some `inline code with **formatting**`
+
+Note that this is why you should use the normal apostrophe when typing out possessive nouns or contractions.  Otherwise you may end up with something like:
+
+>I couldn`t believe that he didn`t know that!
+
+Sometimes you need to preserve indentation, too.  In those cases, you can create a block code element by starting every line of your code with four spaces (followed by other spaces that will be preserved).  You can get results like the following:
+
+    public void main(Strings argv[]){
+        System.out.println(""Hello world!"");
+    }
+
+Starting with Windows Community Toolkit v1.4, you can also use GitHub code notification by creating a block surrounded by 3x\` (3 backticks). This can also be used with Language Identifiers on the entering backticks, such as:
+
+\`\`\`csharp
+
+public static void Main(string[] args)
+{
+  Console.WriteLine(""Hello world!"");
+}
+
+\`\`\`
+
+will produce:
+
+```csharp
+public static void Main(string[] args)
+{
+  Console.WriteLine(""Hello world!"");
+}
+```
+
+*****
+
+# LINKS
+
+There are a couple of ways to get HTML links.  The easiest is to just paste a valid URL, which will be automatically parsed as a link.  Like so:
+
+>http://en.wikipedia.org
+
+However, usually you'll want to have text that functions as a link.  In that case, include the text inside of square brackets followed by the URL in parentheses. So:
+
+>\[Wikipedia\]\(http\://en.wikipedia.org).
+
+results in:
+
+>[Wikipedia](http://en.wikipedia.org).
+
+You can also provide tooltip text for links like so:
+
+>\[Wikipedia\]\(http\://en.wikipedia.org ""tooltip text""\).
+
+results in:
+
+>[Wikipedia](http://en.wikipedia.org ""tooltip text"").
+
+There are other methods of generating links that aren't appropriate for discussion-board style comments.  See the [Markdown Syntax](http://daringfireball.net/projects/markdown/syntax#link) if you're interested in more info.
+
+&nbsp;
+
+Relative links are also supported
+
+>\[Relative Link\]\(/Assets/Photos/Photos.json\)
+
+results in:
+
+>[Relative Link](/Assets/Photos/Photos.json)
+
+&nbsp;
+
+>\[Relative Link 2\]\(../Photos/Photos.json\)
+
+results in:
+
+>[Relative Link 2](../Photos/Photos.json)
+
+**Note:** Relative Links has to be Manually Handled in `LinkClicked` Event.
+
+Custom Scheme's can be added now using `SchemeList` Property. Scheme's should be separated by a comma( , )
+
+*Example*:
+
+If `SchemeList=""companyportal,randomscheme""` then markdown will render
+
+`companyportal://mycompanyportal.com` to companyportal://mycompanyportal.com
+
+and
+
+`randomscheme://www.randomscheme.render` to randomscheme://www.randomscheme.render
+
+*****
+
+# Email Links
+
+Emails can be used as Masked Links.
+
+>\[Email\]\(email@email.com)
+
+will be rendered to [Email](email@email.com)
+
+
+*****
+
+# IMAGES
+
+To add an image, it is almost like a link. You just need to add a \! before.
+
+So inline image syntax looks like this:
+
+>\!\[Helpers Image](https\://raw.githubusercontent.com/CommunityToolkit/WindowsCommunityToolkit/main/Microsoft.Toolkit.Uwp.SampleApp/Assets/Helpers.png)
+
+which renders in:
+
+![Helpers Image](https://raw.githubusercontent.com/CommunityToolkit/WindowsCommunityToolkit/main/Microsoft.Toolkit.Uwp.SampleApp/Assets/Helpers.png)
+
+Rendering Images is now supported through prefix. use property **UriPrefix**
+
+&nbsp;
+
+Example: if you set **UriPrefix** to **ms-appx://** then
+
+>\!\[Local Image](/Assets/NotificationAssets/Sunny-Square.png)
+
+&nbsp;
+
+renders in
+
+![Local Image](/Assets/NotificationAssets/Sunny-Square.png)
+
+You can also specify image width like this:
+
+>\!\[SVG logo](https\://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg =32) (width is set to 32)
+
+>\!\[SVG logo](https\://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg =x64) (height is set to 64)
+
+>\!\[SVG logo](https\://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg =128x64) (width=128, height=64)
+
+which renders in:
+
+![SVG logo](https://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg =32)
+![SVG logo](https://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg =x64)
+![SVG logo](https://upload.wikimedia.org/wikipedia/commons/0/02/SVG_logo.svg =128x64)
+
+MarkdownTextblock supports links wrapped with Images.
+
+>\[!\[image](https\://raw.githubusercontent.com/CommunityToolkit/WindowsCommunityToolkit/main/build/nuget.png)](https\://docs.microsoft.com/windows/uwpcommunitytoolkit/)
+
+will render into
+
+[![image](https://raw.githubusercontent.com/CommunityToolkit/WindowsCommunityToolkit/main/build/nuget.png)](https://docs.microsoft.com/windows/uwpcommunitytoolkit/)
+
+and when clicked will go to the Linked Page.
+
+MarkdownTextBlock also supports Reference based links.

+
+# BLOCK QUOTES
+
+You'll probably do a lot of quoting of other redditors.  In those cases, you'll want to use block quotes.  Simple begin each line you want quoted with a right angle bracket (>).  Multiple angle brackets can be used for nested quotes.  To cause a new paragraph to be quoted, begin that paragraph with another angle bracket.  So the following:
+
+    >Quote1
+
+    >Quote2.1
+    >>Quote2.Nest1.1
+    >>
+    >>Quote2.Nest1.2
+    >
+    >Quote2.3
+
+    >Quote3.1
+    >Quote3.2
+
+    >Quote4.1
+    >
+    >Quote4.2
+
+    >Quote5.1
+    Quote5.2
+
+    >Quote6
+
+    Plain text.
+
+Is displayed as:
+
+
+>Quote1
+
+>Quote2.1
+>>Quote2.Nest1.1
+>>
+>>Quote2.Nest1.2
+>
+>Quote2.3
+
+>Quote3.1
+>Quote3.2
+
+>Quote4.1
+>
+>Quote4.2
+
+>Quote5.1
+Quote5.2
+
+>Quote6
+
+Plain text.
+

+
+# EMOJIS
+
+You can use nearly all emojis from this [list](https://gist.github.com/rxaviers/7360908). Text like `:smile:` will display :smile:  emoji.
+
+*****
+
+# MISCELLANEOUS
+
+### Yaml Headers
+
+The parsing of YAML metadata is rendered as a form.  For example:
+
+title|date
+:-:|:-:
+Windows Community Toolkit|2018/10/17
+
+Which is produced with the following markdown:
+
+>`---`
+>`title: Windows Community Toolkit`
+>`date: 2018/10/17`
+>`---`
+
+When you use YAML, you should pay attention to:
+
+* Must be written at the beginning of the document.
+
+* The start and end are represented by three short horizontal lines respectively.
+
+* The format should conform to the YAML specification.
+
+
+
+### Tables
+
+Reddit has the ability to represent tabular data in fancy-looking tables.  For example:
+
+some|header|labels
+:---|:--:|---:
+Left-justified|center-justified|right-justified
+a|b|c
+d|e|f
+
+Which is produced with the following markdown:
+
+>`some|header|labels`
+>`:---|:--:|---:`
+>`Left-justified|center-justified|right-justified`
+>`a|b|c`
+>`d|e|f`
+
+All you need to produce a table is a row of headers separated by ""pipes"" (**|**), a row indicating how to justify the columns, and 1 or more rows of data (again, pipe-separated).
+
+The only real ""magic"" is in the row between the headers and the data.  It should ideally be formed with rows dashes separated by pipes.  If you add a colon to the left of the dashes for a column, that column will be left-justified.  To the right for right justification, and on both sides for centered data.  If there's no colon, it defaults to left-justified.
+
+Any number of dashes will do, even just one.  You can use none at all if you want it to default to left-justified, but it's just easier to see what you're doing if you put a few in there.
+
+Also note that the pipes (signifying the dividing line between cells) don't have to line up.  You just need the same number of them in every row.
+
+### Escaping special characters
+
+If you need to display any of the special characters, you can escape that character with a backslash (\\).  For example:
+
+>Escaped \\\*italics\\\*
+
+results in:
+
+>Escaped \*italics\*
+
+###Horizontal rules
+
+Finally, to create a horizontal rule, create a separate paragraph with 5 or more asterisks (\*).
+
+>\*\*\*\*\*
