Which connections needed to Flash new Firmware?

Q: Which connections are needed to flash new firmware?

I made this little sketch to remind me to the connections needed to Flash new firmware to the ESP modules. look at the note "flash" and this pin should be grounded during the reboot of the ESP. This puts the ESP in "flash" mode.

TX (blue) and Rx (white) are for the serial connections.
