Request Decryption Password for Config File

While attempting to build the Simplenote Electron client, I need to decrypt the `config.json.enc` file to generate `config-local.json`, but I don’t know the decryption password. When executing `make decrypt_conf` as per project documentation, I encountered the following issues:

1. The command prompts for an AES-256-CBC decryption password, but no related password information was found.
2. Checked project documentation (e.g., `README.md`) and existing Issues, but found no clues about the password.

Execute the decryption command:
make decrypt_conf
The system prompts for a password:
enter aes-256-cbc decryption password:

I'm a beginner exploring open-source projects, and Simplenote Electron is my first attempt to build from source. I would appreciate it if someone could address my concerns.

Start with README.md and the make decrypt_conf command, then inspect how config.json.enc is used to produce config-local.json. Confirm where a contributor should obtain the decryption password or whether the setup instructions are incomplete. Done means a beginner can follow the documented build steps without an unanswered password prompt.
