+# Too Many Watch Flags
+
+#### Why This Error Occurred
+
+When you ran the `micro-dev` command with the `--cold` flag (which disables hot reloading), you've defined more flags that are also related to hot reloading. This is not allowed!
+
+#### Possible Ways to Fix It
+
+When using `--cold`, you cannot use `--watch` or `--poll`. To use one of the latter two flags, you need to enable hot reloading (leave the `--cold` flag away).
