+#### \_\_init\_\_.py
+    from flask import Blueprint
+    from flaschengeist.modules import Plugin
+    
+        
+    example_bp = Blueprint("example", __name__, url_prefix="/example")
+    permissions = ["example_hello"]
+    
+    class PluginExample(Plugin):
+        def __init__(self, conf):
+            super().__init__(blueprint=example_bp, permissions=permissions)
+
+        def install(self):
+            from flaschengeist.system.database import db
+            import .model
+            db.create_all()
+            db.session.commit()
+
+
+    @example_bp.route("/hello", methods=['GET'])
+    @login_required(roles=['example_hello'])
+    def __hello(id, **kwargs):
+        return "Hello"
+
+#### model.py
+Optional, only needed if you need your own models (database)
+
+    from flaschengeist.system.database import db
+    
+    
+    class ExampleModel(db.Model):
+        """Example Model"""
+        __tablename__ = 'example'
+        id = db.Column(db.Integer, primary_key=True)
+        description = db.Column(db.String(240))
+
+#### setup.py
+    from setuptools import setup, find_packages
+    
+    setup(
+        name="flaschengeist-example-plugin",
+        version="0.0.0-dev",
+        packages=find_packages(),
+        install_requires=[
+            "flaschengeist >= 2",
+        ],
+        entry_points={
+            "flaschengeist.plugin": [
+                "example = flaschengeist-example-plugin:ExampleModel"
+            ]
+        },
+    )
+
+## Tips and Tricks
+### Code formatting
+We use [Black](https://github.com/psf/black) as the code formatter.
+
+Installation:
+
+    $ pip install black
+
+Usage:
+
+    $ black -l 120 DIRECTORY_OR_FILE
+
+
+### Git blame
+When using `git blame` use this to ignore the code formatting commits:
+
+    $ git blame FILE.py --ignore-revs-file .git-blame-ignore-revs
+Or if you just want to use `git blame`, configure git like this:
+
+    $ git config blame.ignoreRevsFile .git-blame-ignore-revs
+
+#### Ignore changes on config
+    git update-index --assume-unchanged flaschengeist/flaschengeist.toml
