+## Knowledge base
+
+Welcome to my knowledge base!
+
+Over the years, I've learned a lot about physics, mathematics, and computing.
+These are vast, difficult subjects, and I've spent many hours of my life
+trying to make sense of obscure, poorly explained concepts.
+To help me remember what I learn, I write notes in LaTeX.
+
+This knowledge base is based on my notes, and
+is freely available to anyone who needs it.
+I hope it helps you in your studies or work.
+Currently there's isn't much here yet,
+but I have over 200 pages of LaTeX waiting to be converted.
+
+Keep in mind that I'm only human,
+so there are probably mistakes in my work.
+I take no responsibility for any injuries incurred as a consequence.
+If you're working on something important,
+you should check things yourself!
+
+The contents of this knowledge base are found here:
+* [List of concepts](/know/concept/)
+* [List of categories](/know/category/)
