You can download the latest version of Tree Project by clicking here
Tree Project is written in the Python programming language (version 2.7), so you will need to have it installed. Most *nix operating systems have Python pre-installed, so you are good to go, but others like Windows do not.
You can download Python for your operating system here
Inside the zip file a text file (requirements.txt) can be found, which includes all the required Python libraries that you need to install in order for the Tree daemon to run properly.
Instead of manually installing each library, you can install all of them at once, using pip. PIP is a package manager for Python packages (libraries,modules). You can read more about pip here. Issues might come up for Windows users, so for you convenience, watch the video below.
