 ## Requirements
 
 - python 3.8+
 - requests
+- setuptools (for installation)
 
-## How to install
+## How to run/install
 
-- Windows (standalone): Download the latest EXE from [GitHub](https://github.com/derrod/legendary/releases/latest)
+### Standalone
-- Linux/Windows (requires setuptools to be installed): `python3.8 setup.py install`
+Download the latest `legendary` or `legendary.exe` binary from [the latest release](https://github.com/derrod/legendary/releases/latest)
+and move it to somewhere in your `$PATH`/`%PATH%`. Don't forget to `chmod +x` it on Linux.
 
-A PyPI package will follow once it has gotten more testing.
+The Windows .exe and Linux executable were created with PyInstaller and will run standalone even without python being installed.
+Note that on Linux glibc >= 2.25 is required, so older distributions such as Ubuntu 16.04 or Debian stretch will not work.
 
-The Windows .exe was created with PyInstaller and will run standalone without python being installed.
+### Python package
+
+(A PyPI package will follow once it has gotten more testing.)
+
+- Install python3.8, setuptools and requests
+- Clone the git repository
+- Run `python3.8 setup.py install`
+
+#### Ubuntu 20.04 example
+
+Ubuntu 20.04's standard repositories include everything needed to install legendary:
+````bash
+sudo apt install python3 python3-requests python3-setuptools-git
+git clone https://github.com/derrod/legendary.git
+cd legendary
+sudo python3 setup.py install
+````
+
+Note that in this example we used `sudo` to install the package on the system, this may not be advisable depending on your setup.
+
+### Directly from the repo (for dev/testing)
+
+- Install python3.8 and requests (optionally in a venv)
+- cd into `legendary/` (the folder with `cli.py`)
+- run `PYTHONPATH=.. python3.8 cli.py`
