+# Add a notification way
+
+Adding a new notification way is quite simple.
+
+First, you need to think about how you will configure it.
+As example, here’s how gotify notifications are configured:
+```yaml
+gotify:
+  - url: https://example.org
+    tokens:
+      - foo
+      - bar
+```
+
+Feel free to open an issue to discuss about your notification way or its configuration before coding!
+See [#50](https://framagit.org/framasoft/framaspace/argos/-/issues/50) for example.
+
+Then, you’ll need to add the pydantic schema matching your config in [`argos/schemas/config.py`](https://framagit.org/framasoft/framaspace/argos/-/blob/main/argos/schemas/config.py).
+
+For gotify, it’s:
+```python
+class GotifyUrl(BaseModel):
+    url: HttpUrl
+    tokens: List[str]
+```
+
+Add the schema to the `General` schema in the same file (don’t forget to make it optional).
+
+For gotify, we added this:
+```python
+    gotify: Optional[List[GotifyUrl]] = None
+```
+
+Finally, write a function which use your new notification way in [`argos/server/alerting.py`](https://framagit.org/framasoft/framaspace/argos/-/blob/main/argos/server/alerting.py) and use it in the `handle_alert` function of the same file.
