# Custom Layers

You can write your own custom layers, and integrate them into your Tensorleap model.

To set up your custom layer, open the [Integration Scripts](/user-interface/resources-management/integration-scripts.md) editor and add a class that describes your custom layer.\
\
Then, register your custom layer with the `@tensorleap_custom_layer` decorator to support your layer.\
\
For example, here we add a custom dense layer:

```python
from code_loader.inner_leap_binder.leapbinder_decorators import tensorleap_custom_layer

# This class must inherit from tf.keras.layers.Layer
@tensorleap_custom_layer(name='CustomDense')
class CustomDense(tf.keras.layers.Layer):
    def __init__(self, n, **args):
        super(CustomDense, self).__init__()
        self.n = n
        self.dense = tf.keras.layers.Dense(self.n)

    def call(self, inputs):
        return self.dense(inputs)

    def get_config(self):
        config = super().get_config()
        config.update({
            "n": self.n,
        })
        return config
```

Now, you can upload a model that includes these layers by following the [Import Model](/user-interface/project/versions/import-model.md) guide.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.tensorleap.ai/tensorleap-integration/writing-integration-code/custom-layers.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
