It allows you to take a measurement at a much lower frequency/periodicity than your regularly scheduled group of measurements. Say you have a set of 12 measurements you take at 50 Hz, you set up the ADC/DMA/TIM to automate that, and you have a 13th measurement you need to take every 2 minutes, instead of interfering with your other measurements, you just inject that request periodically.

STM32F10x_StdPeriph_Lib_V3.5.0\Project\STM32F10x_StdPeriph_Examples\ADC\TIMTrigger_AutoInjection\main.c

There is a windows help file for the firmware library, the source is well commented, and there are examples. The reference manuals and data sheets have all the functional detail. For the processor ARM has manuals, and Joseph Yiu has a good collection of books on the Cortex-Mx parts. The business focus is on commercial customers, with profession engineers. For videos and tutorials you'll probably want to search YouTube and the blogosphere.
