+# Simple SQLite Notes Server
+
+A basic MCP server implementation that demonstrates note-taking functionality using the three core MCP primitives: Resources, Prompts, and Tools.
+
+## Core Concepts
+
+### Resources
+Resources are how clients access data from the server. In this case, they're notes stored in SQLite.
+
+```python
+# Access notes through a custom URI scheme
+note:///example_note   # Gets the content of 'example_note'
+```
+
+### Prompts
+Prompts allow generating text based on server state. Our server has a note summarization prompt that can be styled.
+
+```python
+# Example prompt with style argument
+{
+    "name": "summarize-notes",
+    "arguments": {
+        "style": "academic"  # Can be any style descriptor
+    }
+}
+```
+
+### Tools
+Tools modify server state. We have a simple tool to add new notes.
+
+```python
+# Adding a new note
+{
+    "name": "add-note",
+    "arguments": {
+        "name": "my_note",
+        "content": "This is my note content"
+    }
+}
+```
+
+## Key Implementation Details
+
+### Handler Registration
+All decorated handlers must be inside `__init__`:
+```python
+def __init__(self):
+    super().__init__("sqlite")
+    
+    @self.list_resources()
+    async def handle_list_resources():
+        # Handler code here
+
+    @self.read_resource()
+    async def handle_read_resource():
+        # Handler code here
+```
+
+### Storage
+- Uses SQLite for persistent storage
+- Helper methods handle database operations
+- Clients are notified of state changes
