  `ngrok http 80 -config="C:\Users\jagdish\.ngrok2\my-ngrok-2.yml"`
  format of `ngrok.yml`
	```yml
	version: "2"
	authtoken: <AUTH_TOKEN>
	```

- in shell
 ngrok http 80 (here 80 is port number)
- in termux
 to fix "failed get HOME directory"
first you need to type "whoami" without quote in your termux.
that will showed the user
~ $ whoami
u0_a185l
&nbsp;
copy the output (u0_a185l) for me.
than add the user to path by typing "export USER=u0_a185l"
~ $ export USER=u0_a185
enter.
and re-run ngrok
~ $ ./ngrok

- using wifi instead of mobile data in termux

  simply use proot-distro and use ngrok from there, ngrok if installed in termux will work just have to configure auth-token separately
