+# Creating Custom StreamField Blocks 
+
+## Define Your Custom Block
+
+```python
+from wagtail.core import blocks
+
+# Extend StructBlock 
+class TitleAndTextBlock(blocks.StructBlock):
+    title = blocks.CharBlock(required=True, help_text="Add your title")
+    text = blocks.TextBlock(required=True, help_text="Add additional text")
+
+    class Meta:
+        template = "blocks/title_and_text_block.html"
+        icon = "edit"
+        label = "Title & Text"
+```
+
+## Create a Template for Your Block
+
+This template should be located in your templates directory under a `blocks/` subdirectory.
+
+```html
+# blocks/title_and_text_block.html
+<div class="title-and-text-block">
+    <h2>{{ self.title }}</h2>
+    <p>{{ self.text }}</p>
+</div>
+```
+
+## Add Custom Block to a `StreamField`
+
+```python
+from wagtail.core.models import Page
+from wagtail.core.fields import StreamField
+from wagtail.admin.edit_handlers import FieldPanel, StreamFieldPanel
+
+class MyCustomPage(Page):
+    body = StreamField([
+        ('title_and_text', TitleAndTextBlock()),
+        #  add more block types here as needed
+    ])
+
+    content_panels = Page.content_panels + [
+        StreamFieldPanel('body'),
+    ]
+```
+
+## Migrations
+
+```bash
+python manage.py makemigrations
+python manage.py migrate
+```
+
+## Register Your Block (If Necessary)
+
+Some blocks, like those intended for use with `Snippets` or specific functionalities, may need to be registered with Wagtail's admin to appear in the interface. This is not typically required for blocks used directly in `StreamFields`.
+
+### Tips for Advanced Custom Block Development
+
+- **JavaScript Integration**: For blocks that require dynamic user interaction in the Wagtail admin, consider adding JavaScript enhancements using the `media` class property.
+- **Block Methods**: Override methods like `clean`, `value_from_datadict`, and `get_context` to customize the behavior and context data of your blocks.
+- **Nested Blocks**: Custom blocks can contain other blocks, including more instances of custom blocks, allowing for highly complex data structures.
