hi
all doc we need are in 3 files:
stm32f10x_md.pp
cortexm3_start.inc
cd00171190-stm32f101xx-stm32f102xx-stm32f103xx-stm32f105xx-and-stm32f107xx-advanced-armbased-32bit-mcus-stmicroelectronics.pdf
not simple, but there you can find all needed info
i repeat, not simple and just for silly boys like me..
