@@ -13,3 +13,57 @@ I made several design choices:
  - Homebrew made Form framework based on the homebrew made ORM. Most forms are ModelForms but always require an service to be saved for sake of consistency and structure.
  - !DRY for HMTL/jinja2 templates. For templates Snek does prefer to repeat itself to implement exceptions for a page easier. For Snek it's preffered do a few updates instead of maintaining a complex generic system that requires maintenance regarding templates.
  - No existing chat backend like `inspircd` (Popular decent IRC server written in the language of angels) because I prefer to know what is exactly going on above performance and concurrency limit. Also, this approach reduces as networking layer / gateway layer.

+# Some internals
+
+A few examples of how the system framework works.
+
+## How to create a user
+```python
+# Save user to the table named 'user'
+# Password gets sha256 encrypted with default a salt string
+# of the snek.system.security module.
+
+new_user_object = await app.service.user.register(
+    username="retoor", 
+    password="retoorded"
+)
+```
+
+## Encrypt string
+```python
+from snek.system import security
+
+# Support for both utf and bytes.
+var1 = security.encrypt("data")
+var2 = security.encrypt(b"data")
+
+# Is correct:
+assert(var1 == var2)
+```
+
+## How to create a basic HTML / Markdown view
+```python
+from snek.system.view import BaseView 
+
+class IndexView(BaseView):
+    
+    async def get(self):
+        # The render function supports markdown.
+        # It will render with syntax highlighting.
+        # Just use the .md file extension in the file name.
+        return await self.render("index.html")
+```
+## How to create a FormView
+```python
+from snek.system.view import BaseFormView
+from snek.form.register import RegisterForm
+
+class RegisterFormView(BaseFormView):
+    
+    form = RegisterForm
+```
+## How to register a class view
+```python
+app.routes.add_view("/your-page.html", YourViewClass)
+```
