+## List item spacing
+
+If your list items, task list items or paragraphs need special space between them 
+(increasing spacing between them, but keeping the original line height), 
+`LastLineSpacingSpan` <Badge text="4.0.0" /> can be used:
+
+```java
+final Markwon markwon = Markwon.builder(context)
+        .usePlugin(new AbstractMarkwonPlugin() {
+            @Override
+            public void configureSpansFactory(@NonNull MarkwonSpansFactory.Builder builder) {
+                // or Paragraph, or TaskListItem
+                builder.addFactory(ListItem.class, new SpanFactory() {
+                    @Override
+                    public Object getSpans(@NonNull MarkwonConfiguration configuration, @NonNull RenderProps props) {
+                        return new LastLineSpacingSpan(spacingPx);
+                    }
+                });
+            }
+        })
+        .build();

+## Softbreak new-line
+
+If you want to add a new line when a `softbreak` is used:
+
+```java
+final Markwon markwon = Markwon.builder(context)
+        .usePlugin(new AbstractMarkwonPlugin() {
+            @Override
+            public void configureVisitor(@NonNull MarkwonVisitor.Builder builder) {
+                builder.on(SoftLineBreak.class, new MarkwonVisitor.NodeVisitor<SoftLineBreak>() {
+                    @Override
+                    public void visit(@NonNull MarkwonVisitor visitor, @NonNull SoftLineBreak softLineBreak) {
+                        visitor.forceNewLine();
+                    }
+                });
+            }
+        })
+        .build();
+```
