+# Blog
+
+## Purpose
+This folder contains a collection of blog posts documenting the development process of our application. These blogs serve two key purposes:
+
+1. **For External Audiences**
+
+    The blogs provide insights into the internal program flow and the interaction between components without requiring readers to dive into the source code. They offer a mixed-level overview of how different parts of the system work together.
+
+2. **For Our Team**
+
+    The blogs serve as a record of our decision-making process. By documenting what decisions were made and why, we can track the evolution of our design choices and understand the reasoning behind them. This is invaluable for maintaining consistency across the team.
+
+But keep in mind that these blogs **do not replace** the detailed source code documentation.
+
+## Format
+All blog posts follow the naming convention: `<YYYY-MM-DD>_<Title>.md`
