+# Core plugin <Badge text="3.0.0" />
+
+Since <Badge text="3.0.0" /> with introduction of _plugins_, Markwon
+**core** functionality was moved to a dedicated plugin.
+
+```java
+CorePlugin.create();
+```
+
+## Node visitors
+
+`CorePlugin` registers these `commonmark-java` node visitors:
+* `Text`
+* `StrongEmphasis`
+* `Emphasis`
+* `BlockQuote`
+* `Code`
+* `FencedCodeBlock`
+* `IndentedCodeBlock`
+* `BulletList`
+* `OrderedList`
+* `ListItem`
+* `ThematicBreak`
+* `Heading`
+* `SoftLineBreak`
+* `HardLineBreak`
+* `Paragraph`
+* `Link`
+
+## Span factories
+
+`CorePlugin` adds these `SpanFactory`s:
+* `StrongEmphasis`
+* `Emphasis`
+* `BlockQuote`
+* `Code`
+* `FencedCodeBlock`
+* `IndentedCodeBlock`
+* `ListItem`
+* `Heading`
+* `Link`
+* `ThematicBreak`
+
+
+:::tip
+By default `CorePlugin` does not register a `Paragraph` `SpanFactory` but
+this can be done in your custom plugin:
+
+```java
+Markwon.builder(context)
+        .usePlugin(new AbstractMarkwonPlugin() {
+            @Override
+            public void configureSpansFactory(@NonNull MarkwonSpansFactory.Builder builder) {
+                builder.setFactory(Paragraph.class, (configuration, props) -> 
+                        new ForegroundColorSpan(Color.RED));
+            }
+        })
+```
+:::
+
+## Props
+These props are exported by `CorePlugin` and can be found in `CoreProps`:
+* `Prop<ListItemType> LIST_ITEM_TYPE` (BULLET | ORDERED)
+* `Prop<Integer> BULLET_LIST_ITEM_LEVEL`
+* `Prop<Integer> ORDERED_LIST_ITEM_NUMBER`
+* `Prop<Integer> HEADING_LEVEL`
+* `Prop<String> LINK_DESTINATION`
+* `Prop<Boolean> PARAGRAPH_IS_IN_TIGHT_LIST`
+
+:::warning List item type
+Before <Badge text="3.0.0" /> `Markwon` had 2 distinct lists (bullet and ordered). 
+Since <Badge text="3.0.0" /> a single `SpanFactory` is used, which internally checks 
+for `Prop<ListItemType> LIST_ITEM_TYPE`.
+Beware of this if you would like to override only one of the list types. This is
+done to correspond to `commonmark-java` implementation.
+:::
+
+---
+
+:::tip Soft line break
+Since <Badge text="3.0.0" /> Markwon core does not give an option to
+insert a new line when there is a soft line break in markdown. Instead a
+custom plugin can be used:
+
+```java
+final Markwon markwon = Markwon.builder(this)
+        .usePlugin(new AbstractMarkwonPlugin() {
+            @Override
+            public void configureVisitor(@NonNull MarkwonVisitor.Builder builder) {
+                builder.on(SoftLineBreak.class, (visitor, softLineBreak) ->
+                        visitor.forceNewLine());
+            }
+        })
+        .build();
+```
+:::
+
+:::warning
+Please note that `CorePlugin` will implicitly set a `LinkMovementMethod` on a TextView
+if one is not present. If you wish to customize a MovementMethod that is used, apply
+one manually to a TextView (before applying markdown) or use the [MovementMethodPlugin](/docs/core/movement-method-plugin.md)
+which accepts a MovementMethod as an argument.

+# Movement method plugin
+
+`MovementMethodPlugin` can be used to apply a `MovementMethod` to a TextView
+(important if you have links inside your markdown). By default `CorePlugin`
+will set a `LinkMovementMethod` on a TextView if one is missing. If you have
+specific needs for a `MovementMethod` and `LinkMovementMethod` doesn't answer

 Please note, that _by default_ tables have limitations. For example, there is no support
 for images inside table cells. And table contents won't be copied to clipboard if a TextView
 has such functionality. Table will always take full width of a TextView in which it is displayed.
