 # Quickstart
+
+`FastAPI-Admin` is easy to mount your `FastAPI` app, just need a few configs.
+
+## Mount Admin App
+
+First, you need mount the app from `FastAPI-Admin` as a sub application of `FastAPI`.
+
+```python
+from fastapi_admin.app import app as admin_app
+from fastapi import FastAPI
+
+app = FastAPI()
+app.mount("/admin", admin_app)
+
+```
+
+## Configure Admin App
+
+There are some configs to configure the admin app, and you need to configure it on startup of `FastAPI`.
+
+```python
+from fastapi_admin.app import app as admin_app
+from fastapi_admin.providers.login import UsernamePasswordProvider
+
+login_provider = UsernamePasswordProvider(user_model=User, enable_captcha=True)
+
+
+@app.on_event("startup")
+async def startup():
+    redis = await aioredis.create_redis_pool("redis://localhost", encoding="utf8")
+    admin_app.configure(
+        logo_url="https://preview.tabler.io/static/logo-white.svg",
+        login_logo_url="https://preview.tabler.io/static/logo.svg",
+        template_folders=[os.path.join(BASE_DIR, "templates")],
+        login_provider=login_provider,
+        maintenance=False,
+        redis=redis,
+    )
+```
+
+The full list of configs can be found in
