3. To generate a new `username:password`, use `htpasswd -nb user pass`, then copy user to `DASHBOARD_USER` and pass to `DASHBOARD_PASSWORD` in .env file

describes how to generate a BasicAuth password. The above method does not work as Traefik basicuth explains:

# Note: when used in docker-compose.yml all dollar signs in the hash need to be doubled for escaping.
# To create user:password pair, it's possible to use this command:
# echo $(htpasswd -nB user) | sed -e s/\\$/\\$\\$/g

Request to update

• Readme.md with the above note on escaping the $ dollar signs in the password by adding the echo-sed.
• env.example with a password generated by: echo $(htpasswd -nb user pass) | sed -e s/\$/\$\$/g
