+# ADM-ZIP for NodeJS
+
+ADM-ZIP is a pure JavaScript implementation for zip data compression for [NodeJS](https://nodejs.org/).
+
+<a href="https://github.com/cthackers/adm-zip/actions/workflows/ci.yml">
+  <img src="https://github.com/cthackers/adm-zip/actions/workflows/ci.yml/badge.svg" alt="Build Status">
+</a>
+
+# Installation
+
+With [npm](https://www.npmjs.com/) do:
+
+    $ npm install adm-zip
+
+**Electron** file system support described below.
+
+## What is it good for?
+
+The library allows you to:
+
+-   decompress zip files directly to disk or in memory buffers
+-   compress files and store them to disk in .zip format or in compressed buffers
+-   update content of/add new/delete files from an existing .zip
+
+# Dependencies
+
+There are no other nodeJS libraries that ADM-ZIP is dependent of
+
+# Examples
+
+## Basic usage
+
+```javascript
+var AdmZip = require("adm-zip");
+
+// reading archives
+var zip = new AdmZip("./my_file.zip");
+var password = "1234567890";
+var zipEntries = zip.getEntries(); // an array of ZipEntry records - add password parameter if entries are password protected
+
+zipEntries.forEach(function (zipEntry) {
+    console.log(zipEntry.toString()); // outputs zip entries information
+    if (zipEntry.entryName == "my_file.txt") {
+        console.log(zipEntry.getData().toString("utf8"));
+    }
+});
+// outputs the content of some_folder/my_file.txt
+console.log(zip.readAsText("some_folder/my_file.txt"));
+// extracts the specified file to the specified location
+zip.extractEntryTo(/*entry name*/ "some_folder/my_file.txt", /*target path*/ "/home/me/tempfolder", /*maintainEntryPath*/ false, /*overwrite*/ true);
+// extracts everything
+zip.extractAllTo(/*target path*/ "/home/me/zipcontent/", /*overwrite*/ true);
+
+// creating archives
+var zip = new AdmZip();
+
+// add file directly
+var content = "inner content of the file";
+zip.addFile("test.txt", Buffer.from(content, "utf8"), "entry comment goes here");
+// add local file
+zip.addLocalFile("/home/me/some_picture.png");
+// get everything as a buffer
+var willSendthis = zip.toBuffer();
+// or write everything to disk
+zip.writeZip(/*target file name*/ "/home/me/files.zip");
+
+// ... more examples in the wiki
+```
+
+For more detailed information please check out the [wiki](https://github.com/cthackers/adm-zip/wiki).
+
+## Electron original-fs
+
+ADM-ZIP has supported electron **original-fs** for years without any user interractions but it causes problem with bundlers like rollup etc. For continuing support **original-fs** or any other custom file system module. There is possible specify your module by **fs** option in ADM-ZIP constructor.
+
+Example:
+
+```javascript
+const AdmZip = require("adm-zip");
+const OriginalFs = require("original-fs");
+
+// reading archives
+const zip = new AdmZip("./my_file.zip", { fs: OriginalFs });
+.
+.
+.
