 The previous version of k8, v0.2.5, was built on top of v8-3.16.4 released on

+ten years later. It brings ES6 features including but not limited to the "let"
 keyword to define local variables, Java-like classes and back-tick strings.
 
 Due to the lack of the SetIndexedPropertiesToExternalArrayData() API in v8, it
 is not possible to keep full backward compatibility with older k8 versions.
-Nonetheless, we have tried to retain commonly used methods such that the
-several popular k8 scripts can mostly work. We also introduced new file I/O
-functions to avoid clashes with the File classes in other JavaScript runtimes.

 K8 aims to solve this problem. With synchronous I/O APIs, JavaScript can be a
 powerful language for developing command-line tools.
 
+## Installation

+It is recommended to download precompiled binaries. If you want to compile k8,
+you need to compile Node.js which bundles v8 and provides a more convenient way
+build v8. As the v8 APIs are fast changing, both Node.js and k8 only work with
+specific versions of v8. The k8-1.x branch is known to work with node-18.x but
+not 19.x or higher. It is also worth noting that node-18.20.x upgraded
+[c-ares][c-ares] which is now incompatible with older glibc. Node-18.19.1 is
+the most recent version that can be compiled on CentOS 7.
