My First Contribution to an Open Source Project: A story

Although I have been programming for a while (~10 years since I first learn programming), I have not yet made any (significant) contributions to existing works. I have done many projects, but all of them are either myself only or me and another designer. This changed last October, when I start contributing to AviSynth+, a modern fork of original AviSynth project, seriously. For a note, AviSynth is a script-based, non-linear video editing program/library.
