You tie it to ground to boot from flash. If you don't ever need to boot from a boot loader or SDRAM, you can permanently solder it to ground. But in my case when I fucked up and needed to prevent my flash code from running, I could either hold the reset low or pull BOOT0 high to avoid executing bad code from flash, before I could erase/reprogram the chip. Thats how you unbrick it.
