Missing .env.example file in repo

[emanuelb]

file was removed in commit https://github.com/bithyve/hexa/commit/4840f740cf882bed61cdf83f5280d3b866a9fe4a

but instructions in README.md file say:

Copy the contents on .env.example to a new .env file.

and compiling latest version 2.80 with ./gradlew assembleRelease shows:

Configure project :app
Reading env from: .env

src/bitcoin/HexaConfig.ts picks default dev env even if .env is not present
