From 04cd62022c8eb1c82736aa3f8fae17c1510dabc3 Mon Sep 17 00:00:00 2001 From: Pon easwaran Date: Wed, 18 Jun 2025 22:26:55 +0530 Subject: [PATCH 1/4] add running instructions & note extended --period fix (closes #58) What was added: A new Running Locally section in README.md with step-by-step instructions: Clone the repo Build/install via perl Makefile.PL, make, and make install Example usage with --author, --all, and an extended --period value (e.g., --period=-36) A note under Fixes explaining the removal of the hardcoded --since="13 months" cap to support longer history visualization. Why it was done: The missing setup and usage examples caused confusion among users testing the extended-period functionality. Explicit documentation ensures users can verify and utilize the feature fix (#58) immediately.
