+`pio lib install <https://docs.platformio.org/en/latest/userguide/lib/cmd_install.html>`__ command.

+
+Use the ``type`` configuration variable to select the method used. The additional configuration
+settings vary by method:
+
+- **bit_bang**: The simplest method and available on all platforms. However, it can produce quite a bit of flickering,
+  and so is not recommended for use. On ESP8266, supports pins GPIO0-GPIO15, on ESP32 pins GPIO0-GPIO31.
+
+- **esp8266_dma**: The recommended method for ESP8266s. Only available on pin GPIO3.
+
+- **esp8266_uart**: An alternative method for ESP8266s that uses the UART peripheral to send data.
+  Available on pin GPIO1 for bus 0, and GPIO2 for bus 1. Additional options:
+
+  - **bus** (*Optional*, int): The UART bus to use. If 0, the logger ``baud_rate`` option must 
+    be set to 0 and logs over USB/serial won't work.
+  - **async** (*Optional*, boolean): Use an asynchronous transfer. Defaults to ``false``. If enabled,
+    the logger must be disabled even if bus 1 is used.
+
+- **esp32_i2s**: The recommended method for ESP32. Available on all output pins. Additional options:
+
+  - **bus** (*Optional*): The I2S bus to use. The ESP32 has bus 0 or 1 available, but the ESP32-S2 only bus 0.
+    One of ``0``, ``1``, ``dynamic``.
+
+- **esp32_rmt**: An alternative method for ESP32 that uses the RMT peripheral to send data.
+  Available on all output pins. Additional options:
+
+  - **channel** (*Optional*): The RMT channel to use. The ESP32 has channels 0-7, ESP32-S2 0-3 and ESP32-C3 0-1.
+    Defaults to 6 on ESP32, and 1 on other ESP32 variants.
+
+The following method is available only for two-wire chips (specify ``data_pin`` and ``clock_pin``):
+
+- **spi**: Uses the hardware SPI interface to transmit the data. Available on both ESP platforms.
+  Additional options:
+
+  - **bus** (*Optional*, string): On ESP32s the SPI bus to be used can be selected. One of ``vspi`` and ``hspi``.
+  - **speed** (*Optional*, int): The frequency to send data with. Defaults to ``10MHz``. One of
+    ``40MHz``, ``20MHz``, ``10MHz``, ``5MHz``, ``2MHz``, ``1MHz``, ``500KHz``.
+  
+  On ESP8266 only GPIO13 can be used for ``data_pin`` and only GPIO14 can be used for ``clock_pin``.
+
+The ``method`` key also accepts a short-hand syntax consisting of a single value for historic reasons. Usage of
+this method is no longer recommended, but documented here for reference purposes. Possible values were:
+
+- ``ESP8266_DMA`` (for ``esp8266_dma``)

+- ``ESP8266_ASYNC_UART1`` (for ``esp8266_uart`` on bus 1 with async enabled)
+- ``ESP32_I2S_0`` (for ``esp32_i2s`` on bus 0)

Users with a manually calibrated setup are encouraged to check their the installations to ensure proper output.
