+## DeepNLP Equation
+
+DeepNLP Equation is a repo/website (http://www.deepnlp.org/equation) to host latex code and text explanation of equations in all science and quantitative fields.
+We will continue to collect and grow the size of resources and hopefully this repo of resources can be helpful to research and development of large language model, machine learning and AI4Science communities.
