 The simplest way to use `ini` is with the `parse` function:
 
-```mbt test
-let config_str =
-  #|[server]
-  #|host=localhost
-  #|port=3000
-let ini = @ini.parse(config_str)
-let host = ini.get(section="server", "host").unwrap()
-inspect(host, content="localhost")
+```mbt check
+///|
+test {
+  let config_str =
+    #|[server]
+    #|host=localhost
+    #|port=3000
+  let ini = @ini.parse(config_str)
+  let host = ini.get(section="server", "host").unwrap()
+  inspect(host, content="localhost")
+}
 ```
