 This program depends on NumPy (for arrays and mathematical operations) and Librosa (for audio analysis and beat extraction).
 If you don't have these dependencies installed, they'll be automatically downloaded:
 
-```sh
-pip install git+https://github.com/arkrow/PyMusicLooper.git
+For the full program with tag preservation and direct playing support:
 ```
+pip install git+https://github.com/arkrow/PyMusicLooper.git#egg=pymusiclooper[complete]
+```
+
+The "complete" version requires:
+- [pytaglib](https://github.com/supermihi/pytaglib) for tag preservation (see their [installation notes](https://github.com/supermihi/pytaglib#installation-notes) for problems with libtag dependency on MacOS/Linux)
+- [mpg123](https://www.mpg123.de/download.shtml) to play music endlessly through the terminal.
 
-To play music endlessly through the terminal, the external library `mpg123` is required. Available through the following link: (https://www.mpg123.de/download.shtml).
+For just the essentials (exporting intro/loop/outro sections to WAV, or the loop points in samples):
+```
+pip install git+https://github.com/arkrow/PyMusicLooper.git
