-## Dependencies
+## Official host
+
+We currently host the client at [https://app.fosscord.com](https://app.fosscord.com).
+You can use it to connect to our official instance by default,
+or you can use it to connect to your own by editing your local storage to include the `routeSettings` key with the below example content:
+```json
+{
+	"api":"https://staging.fosscord.com/api/v9",
+	"cdn":"https://cdn.staging.fosscord.com",
+	"gateway":"wss://gateway.staging.fosscord.com",
+	"invite":"https://staging.fosscord.com/invite",
+	"template":"https://staging.fosscord.com/template",
+	"gift":"https://staging.fosscord.com/gift",
+	"scheduledEvent":"https://staging.fosscord.com/events"
+}
+```
+
+Replace the above endpoints with your own. If your domain name is `https://whatever.notasite`, then you'll most likely want to enter
+`https://whatever.noasite/api/v9` for the API endpoint, etc.
