 On Windows, Micronucleus requires drivers to be installed; this can be done by running the included batch file - but the Arduino IDE will not do that for you. When you install it, the path to the batch file will be printed in the console window. Alternately, the drivers can also be downloaded separately from [https://github.com/digistump/DigistumpArduino/releases/download/1.6.7/Digistump.Drivers.zip](https://github.com/digistump/DigistumpArduino/releases/download/1.6.7/Digistump.Drivers.zip) - unzip, run installer.
 
 ## Uploading to a Micronucleus board
-When you upload to a Micronucleus board, you will be prompted to "Please plug in the device" (there is a 60-second timeout on this). At this point, the board must be reset and/or plugged in. Depending on the bootloader version it is running, only certain types of reset will enter the bootloader (see below); almost all will enter the bootloader on a power-on reset when it detects that it is connected to a USB port (as opposed to just power). About a second after this reset, the computer will recognize the device, and the upload will commence. By scrolling up in the console output, you can also see the maximum sketch size that the bootloader reported was available. Often, this is not the same as what the ATTinyCore part-specific documentation specifies or what the compiler tests against. This is expected because have a different version of the bootloader; as Micronucleus development has progressed, improvements have been made to reduce the size of the bootloader. The bootloader entry mode also has an impact on flash usage. Additionally, "aggressive" versions of the bootloader have been made - these use optimizations to reduce the size of the bootloader which come at the cost of it doing a worse job at USB, which may cause it to malunction on specific chips, or with specific USB hosts (currently we do not supply such firmware with this core). While, as supplied, most of these boards come with recent versions of Micronucleus with (nearly) the same amount of usable space as the ones included with this package *many ATtiny85 based boards in the wild have a primitive version* that leaves only around 6k free for your sketch! Fortunately, upgrading is easy, even if reset has been disabled.

 Currently, where multiple versions of the bootloader are included with different amounts of free space, the currently selected one is used (and if the bootloader actually on the board has less, Micronucleus will stop you); I may revisit this decision in a future version
