+## ARTEMIS 3 .SPEC FILES
+
+Artemis 3 .spec files are used by the package **pyinstaller** (https://www.pyinstaller.org/) to build a single standalone executable. The extreme versatility of this package is the fact that every external dependency is already embedded into the bundle. The interpreter of Python 3 is also included. Python 
+
+## Requirements
+- Python 3.7.0+
+- Pyinstaller
+
+## Package Building
+**IMPORTANT:** *To generate the standalone, you must use an operating system that coincides with the target one (pyinstaller doesn't allow cross-compilation).* 
+1. Download a fresh copy of the git repository.
+2. Choose the target OS in `spec_files` folder and copy the whole content into `src`
+3. Open a terminal into `src` and run:
+```
+pyinstaller Artemis.spec
+```
+4. The ready-to-use compiled software is now present into `src/dist` folder.
