 # rfc2gemini
 
-Converts the index of RFCs to gemtext (text/gemini), to be served via Gemini.
\ No newline at end of file
+Converts the index of [RFCs](https://www.rfc-editor.org/) to gemtext (`text/gemini`), to be served via [Gemini](https://en.wikipedia.org/wiki/Gemini_(protocol)).
+
+## Installation
+
+Download the program. Check that the paths in `Makefile` and `rfc-index2gemini.py` are OK for you. Then run the program periodically, for
+instance through cron:
+
+```
+# RFC index
+52 1,5,9,13,17,21 * * *  (cd /path/to/RFC-index; make all)
+```
