 # ⚡️ QuickJS - A mighty JavaScript engine
 
-Friendly [QuickJS](https://bellard.org/quickjs) fork focused on reigniting the project.
+Friendly [QuickJS]() fork focused on reigniting the project.
 
-🚧 Work in progress.
+## Overview
 
-test.
+In October 2023 [@bnoordhuis] and [@saghul] decided to fork the [QuickJS] project with
+the aim of reigniting it. They reached out to the original authors ([@bellard] and [@chqrlie])
+about their intentions.
+
+As of December 2023 the initial goal was somewhat accomplished. [@bellard] resumed working on
+the project and both parties have been pulling patches from each other since.
+
+As of early 2024 both projects agree the proper path forward involves merging both projects
+and combining the efforts. While that may take a while, since both projects diverged in certain
+areas, there is willingness to go in this direction from both sides.
