5		-except that where it mentions port 80, you **must** use port 443.  You should be using Python3. You will also probably need to install "npm" in addition to the packages he mentions. You **must** use https to connect, which means you need a certificate.  Everything else seems pretty straight-forward and I have verified that it works, pulling numbers from Dexcom share, if you configure BRIDGE_USER_NAME, BRIDGE_PASSWORD, and "bridge" under the Enable options.  Everywhere pages mention changing the "Config Vars", this maps directly to the environment variables in the "start.sh" file.

10	10	* The reason MongoDB 2.4 is installed under Raspian, seems to be because later versions of MongoDB are 64 bit and Raspian is 32 bit.  You would need to install a 64 bit version of Linux, such as [[Ubuntu>>https://pimylifeup.com/ubuntu-server-raspberry-pi/]], onto your Raspberry Pi and then you can follow the instructions above.
11		-** You can't install a 64 bit Ubuntu onto a Raspberry PI Zero or Zero W, because it requires ARMv7 processor and the Zero series is based on ARMv6.
12		-*** Probably the smallest choice would be Raspberry Pi Model 3 A+.
13		-
14		-I finally ended up using a Raspberry Pi model 3 A+.  This is an ARMv7 processor, so it can do 64 bit Linux, it has built-in Wifi, and it's still small and cheap.  I installed Ubuntu 19 from here:
