+Component/Hub
+-------------
+
+The ``cap1188`` sensor platform allows you to use your CAP1188
+(`datasheet <https://cdn-shop.adafruit.com/datasheets/CAP1188.pdf>`__,
+`Adafruit`_) Capacitive Touch Sensor with ESPHome. The :ref:`I²C <i2c>` bus is
+required to be set up in your configuration for this sensor to work.

+    # Example configuration entry
+    cap1188:
+      id: cap1188_component
+      address: 0x29
+      reset_pin: 14
+      touch_threshold: 0x40
+      allow_multiple_touches: 0x80
+
+    binary_sensor:
+      - platform: cap1188
+        id: touch_key0
+        channel: 0
+        name: "Touch Key 0"
+
+Configuration variables:
+------------------------
+
+The configuration is made up of two parts: The central component, and individual Binary sensors per channel.
+
+- **address** (*Optional*, integer): The I²C address of the sensor. Defaults to ``0x29``.
+- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor.
+- **reset_pin** (*Optional*, :ref:`config-pin`): Set the pin that is used to reset the CAP1188 board on boot.
+- **touch_threshold** (*Optional*, integer): The touch threshold for all channels. This defines the sensitivity for touch detection.
+   - ``0x00``: Maximum sensitivity - Most sensitive to touch
+   - ``0x20``: Default sensitivity
+   - ``0x40``: Medium sensitivity (I used this sensitivity when being used through a 3mm sheet of plastic)
+   - ``0x80``: Minimum sensitivity - Least sensitive to touch
+- **allow_multiple_touches** (*Optional*, boolean): Whether to allow multitouch. Defaults to off.
+
+Binary Sensor
+-------------
+
+The ``cap1188`` binary sensor allows you to use your CAP1188 with ESPHome.
+First, setup a :ref:`cap1188-component` and then use this binary sensor platform to create individual
+binary sensors for each touch sensor.
+
+
+Configuration variables:
+
+
+- **name** (*Optional*, string): The name for the binary sensor.
+- **cap1188_id** (*Optional*, :ref:`config-id`): The ID of the CAP1188 defined above. Useful for multiple CAP1188's on the I²C bus.
+- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
+- **channel** (**Required**, integer): The channel number the CAP1188 the touchkey is connected to.
+- All other options from :ref:`Binary Sensor <config-binary_sensor>`.
+
+.. note::
+
+    SPI is not currently supported. I²C must be used at this time.
