 A simple proxy server created by [@NBTX](https://github.com/NBTX/) for [Postwoman](https://github.com/liyasthomas/postwoman/) and hosted by [Apollo Software](https://apollosoftware.xyz/).
 
+## Installation 📦
+**Proxywoman require `zenity` on Linux. This is available in most distribution package managers.**
+
+We're still working on automated installers. For now, copy the binary to a user-writeable location and launch the application.  
+A dialog will open and explain the certificate installation process - there are more detailed instructions in our [wiki](https://github.com/postwoman-io/proxywoman/wiki).

 *These are bash scripts. In order to execute them on Windows, you will need to use some form of bash shell on Windows. We recommend [Git Bash](https://gitforwindows.org/).*
