+## Tutorial 13: VisualText Version 2
+
+This tutorial shows of verion 2 of the NLP Engine and VisualText. The main difference is the KB View with the new dictionary and KBB files and the great tools for building and maintaining NLP analyzers that feed one into another: [YouTube Video Tutorial 13](https://youtu.be/e-JQTnXEkcg)
+
+### Tutorial 13-a:
+
+This analyzer fetches informational pages from the web on the 50 American states. This is included in one video: [YouTube Video Tutorial 13](https://youtu.be/e-JQTnXEkcg)
+
+### Tutorial 13-b:
+
+This analyzer analyzes the 50 state webpages and creates dictionaries and a knowledge base. This is included in one video: [YouTube Video Tutorial 13](https://youtu.be/e-JQTnXEkcg)
+
+## Tutorial 14: Mod Files
+
+Mod files allow for bundling text, NLP++ code (passes), dictionaries, and knowledge base files into one file that can be easily created and loaded into VisualText (the NLP++ langauge extension for VSCode).: [YouTube Video Tutorial 14](https://youtu.be/dRpGY0SPLSo)
+
+# Tutorial 15: Resolving Ambiguity
+
+This tutorial you will learn about the new mechanisms to help resolve with ambiguity. Ambiguity is when a word in isolation can have more than one meaning. Dealing with ambiguity in NLP++ is a cordinated effort between dictionaries, knowledge bases, and rule matching. [YouTube Video Tutorial 14](https://youtu.be/XLEj1hsS4ME)

+# Tutorial 14 - Mod Files
+
+This tutorial is about Mod files in NLP++. Mod files allow for the bundling of text files, nlp++ files, dictionaries and knowledge base files into one file that can be easily created and loaded. The idea behind mod files is to create useful analyzer capabilities that can be incorporated into exhisting analyzers.
