+### Generate a binder
+
+You need to have Python 3 installed.
+
+Install dependencies: `pdfkit`, `weasyprint`, `wkhtmltopdf`
+
+Add links to download to text files. The links in each text file will be downloaded to their own folder.
+
+Run `./mkbinder.py`. It may take a while, depending on how many links to download.
+
+```
+usage: mkbinder.py [-h] [--backend {pdfkit,weasyprint}]
+
+optional arguments:
+  -h, --help            show this help message and exit
+  --backend {pdfkit,weasyprint}, -b {pdfkit,weasyprint}
+                        change the download backend; default: pdfkit
