What this PR does

In the readme - step 2

When generating the .env file using Command Prompt (cmd) it outputs a .env file that Docker fails to read when trying to spin up the container.

line 1: unexpected character "\"" in variable name "\"DOMAIN=http://localhost:8080#

.env file produced by cmd

"DOMAIN=http://localhost:8080# Remove 'with_grafana' below if you want to use existing grafana# Add 'with_prometheus' below to optionally enable a local prometheus for oncall metrics# e.g. COMPOSE_PROFILES=with_grafana,with_prometheusCOMPOSE_PROFILES=with_grafana# to setup an auth token for prometheus exporter metrics:# PROMETHEUS_EXPORTER_SECRET=my_random_prometheus_secret# also, make sure to enable the /metrics endpoint:# FEATURE_PROMETHEUS_EXPORTER_ENABLED=TrueSECRET_KEY=my_random_secret_must_be_more_than_32_characters_long" 

However, if using PowerShell on Windows, the output format is readable and the user can start the container.

DOMAIN=http://localhost:8080
# Remove 'with_grafana' below if you want to use existing grafana
# Add 'with_prometheus' below to optionally enable a local prometheus for oncall metrics
# e.g. COMPOSE_PROFILES=with_grafana,with_prometheus
COMPOSE_PROFILES=with_grafana
# to setup an auth token for prometheus exporter metrics:
# PROMETHEUS_EXPORTER_SECRET=my_random_prometheus_secret
# also, make sure to enable the /metrics endpoint:
# FEATURE_PROMETHEUS_EXPORTER_ENABLED=True
SECRET_KEY=my_random_secret_must_be_more_than_32_characters_long
