+## Firmware Installation / Firmware Update
 
 If a previous version of the TCD firmware is installed on your device, you can update easily using the pre-compiled binary. Enter the [Config Portal](#the-config-portal), click on "Update" and select the pre-compiled binary file ("xxx.bin") provided in the Release package.

 ### Sound-pack installation
 
-The firmware comes with a sound-pack which needs to be installed separately. The sound-pack is not updated as often as the firmware itself. If you have previously installed the latest version of the sound-pack, you normally don't have to re-install it when you update the firmware. Only if the TCD displays "PLEASE INSTALL SOUND PACK" during boot, a re-installation/update is needed.

If you have previously installed the latest version of the sound-pack, you normally don't have to re-install it when you update the firmware. There will be a message in the Config Portal and the TCD will display "PLEASE INSTALL SOUND PACK" during boot when a new sound-pack needs to be installed.
 
 _Note that installing the sound-pack requires an [SD card](#sd-card)._
 
->A10001986 and CircuitSetup use different sound-packs. If you switch from one version to the other, the matching sound-pack must be re-installed. [A10001986-releases](https://github.com/realA10001986/Time-Circuits-Display/releases) use "sound-pack-twXX", while [CircuitSetup's](https://github.com/CircuitSetup/Time-Circuits-Display/releases) are named "sound-pack-csXX".

The Config Portal will tell you which version is required to be installed.
 
 The first step is to extract the zipped sound-pack (which is included in every Release package). It contains one file named "TCDA.bin".
 
 Next, head to the [Config Portal](#the-config-portal), click on *Update*, select the "TCDA.bin" file in the bottom file selector and click on *Upload*.
