+Rikiki is a small Wiki engine in python3 I built for [Shortest Wiki Contest](http://wiki.c2.com/?ShortestWikiContest).
+
+Rikiki means "tiny" in french.
+
+Fun fact: Rikiki source code is *three times smaller* than this readme file.
+
+
+# Usage
+
+**YOU SHALL NOT USE THIS CODE IN PRODUCTION!**
+
+This code is **NOT SECURE** and it is based onto CGI technology which is **OBSOLETE** for production.
+
+To run this wiki, you need python3 only :
+
+1. Create a folder named "wiki"
+2. Create a sub-folder named "cgi-bin"
+3. Copy rikiki.py inside the "cgi-bin" folder
+4. Run this command from the wiki folder :
+    PYTHONWARNINGS="ignore" python -m http.server --cgi
+
+Now, you can go and visit : http://localhost:8000/cgi-bin/rikiki.py?p=HomePage
+
+
+# Features
+
+As stated in the Shortest Wiki Contest consraints,there are some [Wiki Principles](http://wiki.c2.com/?WikiPrinciples)
+to obey :
+
+* Automatic Link Generation: Each page is in CamelCase. As soon as you write it in source, it is available via a link.
+* Content Editable By All: Totally open, **everyone** can change sources and create more pages.
+* EasyTextInput: Paragraphs are done with breaking lines, link to other pages are done in CamelCase.
+* Back Links: If a page A links to a page B, this page B will display a link to page A.
+
+
+## Constraints
+
+In order to gain bytes, you can't do a lot :
+
+* Only ASCII characters are managed
+* Formating text is *highly* limited ;o)
+* Input textarea should be resized before typing
+* No versioning of sources
