+# 213_21 Fix typo and update outdated repository links in README.md
+
+## 2025/02/27 Fix README.md typo and links
+
+### What
+Fixed a typo in the image alt text and updated all outdated GitHub repository links in `README.md`.
+
+### Why
+1. The image alt text `hesis-level Edits PRE` was missing the leading "T", it should be `Thesis-level Edits PRE`.
+2. Multiple links in `README.md` still pointed to the old repository `github.com/XmacsLabs/mogan` instead of the current `github.com/MoganLab/mogan`. This includes the releases link, clone URL, and repository reference in the documentation section.
+
+### How
+- Fixed typo: `hesis-level` → `Thesis-level` in image alt text
+- Updated GitHub releases link: `XmacsLabs/mogan` → `MoganLab/mogan`
+- Updated git clone URL: `XmacsLabs/mogan` → `MoganLab/mogan`
+- Updated repository reference link: `XmacsLabs/mogan` → `MoganLab/mogan`
