-You can use `snoop.setup()` method to configure and get a new snoop object, then use it globally or in scope. Any parameters passing to `setup()` method should be supported by snoop.
-```python
-import pysnooper.snoop
-
-# use my_snoop to debug. my_snoop will always be enabled, stderr will redirect output to a file
-my_snoop = snoop.setup(output='/my/log/file.log', disable=False)
-
-@my_snoop()
-def foo():
-    x = 5
-    y = 10
-    return x + y

-Notice that `PYSNOOPER_DISABLED` will be invalid if `disable` parameter is specified in `setup()`
+`PYSNOOPER_DISABLED` as an environment variable, can be used to activate or deactivate pysnooner. Pysnooper is deactivated by setting the parameter to a non-empty value, and active by default.
