+## Introduction
+
+ * **Nmap** is a free and open source utility for network exploration and security auditing.
+ * **Zenmap** is a multi-platform graphical frontend and results viewer for Nmap.
+ * **Ncat** is a general-purpose network sending and receiving utility, a reimplementation of Netcat.
+ * **Ndiff** is a an Nmap scan comparison utility.
+ * **Nping** is a tool for packet generation and sending.
+
+This package contains Nmap, Zenmap, Ncat, Ndiff, and Nping. It is intended to work on Intel Macs running **Mac OS X 10.8 or later**.
+
+Installation of all packages is optional. Unselect Zenmap to get just the command-line tool. Unselect Nmap if you prefer to use a copy of Nmap that is already installed. Zenmap will not work without Nmap.
+
+The nmap, ncat, ndiff, and nping command-line binaries will be installed in `/usr/local/bin`, and additional support files will be installed in `/usr/local/share`. The Zenmap application bundle will be installed in `/Applications/Zenmap.app`.
+
+For a full description of Nmap's installation on Mac OS, visit the page:
+[https://nmap.org/book/inst-macosx.html](https://nmap.org/book/inst-macosx.html)
+
+## Requirements
+
+In order to compile, build and run Nmap on Mac OS, you will requiere the followings:
+
+1. **Jhbuild** for bundling and dependencies (see the [BUNDLING file](../BUNDLING.md))
+2. **Xcode** for Mac OS 10.8 or later ([https://developer.apple.com/xcode](https://developer.apple.com/xcode/))
+3. **Xcode Command-line Tools** for Mac OS 10.8 or later ([https://developer.apple.com/downloads](https://developer.apple.com/downloads/) — then download the latest version compatible with your OS version)
+
+## Installation
+
+Ideally, you should be able to just type:
+
+ ./configure
+ make
+ make install
+
+from `nmap/` directory (the root folder).
+
+For far more in-depth compilation, installation, and removal notes, read the **Nmap Install Guide** at [https://nmap.org/book/install.html](https://nmap.org/book/install.html).
+
+## Files in this directory
+
+* [openssl.modules](openssl.modules): This is a Jhbuild moduleset that can be used to build dependencies (openssl, libsvn and libapr) as required for building Nmap, Ncat, Nping and nmap-update. Use it like this:
+
+ ~~~~
+ $ jhbuild -m openssl.modules build nmap-deps
+ ~~~~
+
+* [Makefile](Makefile): The Mac OS X Makefile used to build everything specific to this OS.
+* [BUNDLING.md](BUNDLING.md): A manual on how to setup and use Jhbuild on Mac OS X.
+
+## Zenmap
+
+### Files into `zenmap/install_scripts/macosx/`:
+
+All of the files have to do with packaging on Mac OS X. They are useful only for those wanting to build binary distributions of Zenmap for Mac OS X.
+
+* [Info.plist](../zenmap/install_scripts/macosx/Info.plist): A properties list file template that is filled out by [make-bundle.sh](../zenmap/install_scripts/macosx/make-bundle.sh).
+* [make-bundle.sh](../zenmap/install_scripts/macosx/make-bundle.sh): This script builds a .app bundle. It must be run from the root of the Zenmap source tree. The finished bundle is put in `dist/Zenmap.app`.
+* [zenmap.icns](../zenmap/install_scripts/macosx/zenmap.icns): The icon file for the bundle. It was created using the Icon Composer utility (`$ open -a "Icon Composer"`).
+* [zenmap_auth.c](../zenmap/install_scripts/macosx/zenmap_auth.c): This is a simple wrapper program that attempts to run [launcher.sh](../zenmap/install_scripts/macosx/launcher.sh) with privileges.
+* [launcher.sh](../zenmap/install_scripts/macosx/launcher.sh): A launcher script that configures the environment for Zenmap, Python, and GTK before launching the main Zenmap script file.
+* [zenmap.bundle](../zenmap/install_scripts/macosx/zenmap.bundle): An XML configuration file for gtk-mac-bundler which specifies files and metadata for the application bundle ([https://wiki.gnome.org/Projects/GTK%2B/OSX/Building](https://wiki.gnome.org/Projects/GTK%2B/OSX/Building)).
+
+### Authorization Wrapper:
+
+The **bundling** process is as follows:
+
+1. First, the bundler ([make-bundle.sh](../zenmap/install_scripts/macosx/make-bundle.sh)) look at the bundle XML (`zenmap.bundle`) and copy everything over.
+2. The launcher script ([launcher.sh](../zenmap/install_scripts/macosx/launcher.sh)) gets renamed into the app name (`Zenmap`).
+3. The authorization wrapper is compiled to `Zenmap` so that it is the entry point of the app.
+4. The last part is filling in the [Info.plist template file](../zenmap/install_scripts/macosx/Info.plist) based on the current information in `zenmap.ZenmapCore.Version`.
+
+After the bundling process is done and the app is installed, the **execution** path is as follows:
+
+**Zenmap (zenmap_auth) —> zenmap.bin (launcher.sh) —> python zenmap.py**
+
+## Repositories and Troubleshooting
+
+Nmap uses a read-only repository on **Github** for issues tracking and pull requests. You can contribute at the following address: [https://github.com/nmap/nmap](https://github.com/nmap/nmap).
+
+The read-write repository is managed with **Subversion**. Although, all actual commits are made to our Subversion repository on [https://svn.nmap.org](https://svn.nmap.org/).
+
+In order to be always up to date, you can consult the Changelog here: [https://nmap.org/changelog.html](https://nmap.org/changelog.html).
+
+## The CONTRIBUTING file
+
+General information about contributing to Nmap can be found in the [CONTRIBUTING file](../CONTRIBUTING.md). It contains information specifically about Nmap's use of Github and how contributors can use Github services to participate in **Nmap development**.
