 ## Installation
 
-```shell
+### With pip
-$ pip install pywidevine
-```
 
-> **Note**
+> Since *pip* is pre-installed with Python, it is the most straight forward way to install pywidevine.
-If pip gives you a warning about a path not being in your PATH environment variable then promptly add that path then
-close all open command prompt/terminal windows, or `pywidevine` CLI won't work as it will not be found.
 
-Voilà 🎉 — You now have the `pywidevine` package installed!  
+Simply run `pip install pywidevine` and it will be ready to use from the CLI or within scripts in a minute.
-You can now import pywidevine in scripts ([see below](#usage)).  
+
-A command-line interface is also available, try `pywidevine --help`.
+### With uv
+
+> This is recommended for those who wish to install from the source code, are working on changes in the source code, or
+just simply prefer it's many handy features.
+
+Go to to the official website and [get uv installed](https://docs.astral.sh/uv/getting-started/installation/). Download
+or clone this repository, go inside it, and run `uv run pywidevine --version`. To run scripts, like a `license.py` that
+is importing pywidevine, do `uv run license.py`. Effectively, put `uv run` before calling whatever is using pywidevine.
+For other ways to run pywidevine with uv, see [Running commands](https://docs.astral.sh/uv/guides/projects/#running-commands).
 
 ## Usage
 
-The following is a minimal example of using pywidevine in a script to get a License for Bitmovin's
+There are two ways to use pywidevine, through scripts, or the CLI (command-line interface).
-Art of Motion Demo.
+Most people would be using it through scripts due to complexities working with license server APIs.

+  test           Test the CDM code by getting Content Keys for Bitmovin's...
+```
+
+Every command has further help information, simply type `pywidevine <command> --help`.
+For example, `pywidevine test --help`:
+
+```plain
