 ## Flashing a binary
 We intend to post pre-compiled binaries with each release and are also available [here](https://arctictracker.no/download/). The complicating factor is that there are more than one way to do it and that the firmware consists of multiple parts: The bootloader, the partition table, the webapp, etc.. The most flexible option is probably to use *esptool* or a similar program, but you will need to know some technical details. It is also possible to convert the binary to the UF2 format using *uf2conv* and use a uf2 bootloader.
 
-Download the proper *ArcticTracker_xx.zip* file and unpack it in a directory. Go to that directory and use *esptool* or a similar tool (on Windows, we may use the [*flash download tool*](https://www.espressif.com/en/support/download/other-tools). The *flash_all.sh* script shows how to use *esptool*. The same parameters can be used in the Windows *flash download tool*. On a Linux system you may just run the *flash_all.sh* script to flash everything.
