 # freeCodeCamp Guides
 The freeCodeCamp community is building a massive, searchable "Guide." This reference tool will eventually include thousands of articles that cover all areas of development, design, and data science - all written to be easily understood by people new to coding.
 
-This repo is where we plan and maintain these guide articles, which we then host on our community's wiki-like [guides website](guide.netlify.com).
