Instructions missing

[Manamama]

I am "semi-tech savvy" and I have been using mvt-android for some time now, which has helped me here.
Still, I spent close to half hour troubleshooting the upgrades etc., so my tips:

1. Instead of "here are the install" do tell the users what to do with them, as they are not that obvious - a one-liner or another script would help.
2. As I thought it would be quicker to just clone and compile I went this route, but then I have run into small snags, so here are solutions the other potential users:
   A. Probably the quickest and most fool-proof way to upgrade one's Go is via

git clone https://github.com/udhos/update-golang
cd update-golang
sudo ./update-golang.sh

B. If you then have run into:
bash: /usr/bin/go: No such file or directory
then the most elegant
hash -r
may help.

C. The obvious:

go: updates to go.mod needed; to update it:
	go mod tidy
make: *** [Makefile:70: linux] Error 1

->
go mod tidy
, another line which may be good to also include in this script here.
