 The default behavior is to output the secondary structure visualization to both svg and png. The png requires Inkscape, whose directory must be set by environmental variable `INKSCAPEDIR`.
 
 ## Install
+`draw_rna` is [available on PyPI](https://pypi.org/project/draw-rna/).
 
-Clone this repository to your hard drive and install as follows:
+`pip install draw_rna`
 
-```
-git clone git@github.com:DasLab/draw_rna.git
-cd draw_rna/
-python setup.py install
-```
+Alternatively, clone the Github repository to your hard drive as follows:
+
+`git clone git@github.com:DasLab/draw_rna.git`
 
-*Warning* if you see errors in using the repository, it maybe due to your `draw_rna` directory sitting in a folder like `src/` which already is in your Python Path. in that case, *rename* `draw_rna` to `draw_rna_directory` and/or move it to another spot in your system.
