# Ignore actual env files .env .env.local .env.production .env.staging
# Copy the sample configuration cp .env.sample .env .env.sample
New developers spend hours figuring out why the application isn't starting, only to find they are missing a specific API key. # Ignore actual env files
A well-crafted .env.sample serves as living documentation for your application's configuration. Using comments above each variable, you can document what the variable does, what format it expects, and any constraints or defaults. When environment variables change, the sample file changes with the code. This keeps documentation synchronized with implementation, preventing outdated wikis or READMEs. When environment variables change, the sample file changes
.env.sample answers this question immediately. By providing a complete list of required variables with clear placeholders, new contributors can get the project running in minutes rather than hours, reducing the well-known "missing .env file" frustration. When a sample file is included, developers can simply copy it to .env and fill in their own values, eliminating significant time spent deciphering the required configuration.
