Examples

There are many things that can go wrong in your .env files:

# Next line has leading space which will be removed:
 SPACED=

# Equal signs should not be spaced:
KEY = VALUE

# Quotes won't be preserved after parsing, do not use them:
SECRET="my value"

# Beware of duplicates!
SECRET=Already defined ;(

# Respect the convention, use `UPPER_CASE`:
kebab-case-name=1
snake_case_name=2
