Sure, here is a step-by-step guide on how to use StandardScaler to standardize your data in Python using the sklearn library.

1. Import the necessary libraries:
```python
from sklearn.preprocessing import StandardScaler
import numpy as np
```

2. Create your data. For this example, let's use a simple numpy array:
```python
data = np.array([[0, 0], [0, 0], [1, 1], [1, 1]])
```

3. Initialize the StandardScaler:
```python
scaler = StandardScaler()
```

4. Fit the scaler to your data. This will calculate the mean and standard deviation to be used for scaling:
```python
scaler.fit(data)
```

5. Transform the data using the fitted scaler. This will standardize the data by subtracting the mean and scaling to unit variance:
```python
standardized_data = scaler.transform(data)
```

Now, `standardized_data` is your standardized version of `data`. The mean of `standardized_data` should be close to 0 and its standard deviation should be close to 1.
