-Welcome to MS Entropy's documentation!
-======================================
+Introduction to MS Entropy!
+===========================
 
-Welcome to use this package, you can download the code from `MS Entropy Github repository <https://github.com/YuanyueLi/MSEntropy>`_.
-If you have any question, please send E-mail to :email:`Yuanyue Li <liyuanyue@gmail.com>`
+Thank you for using the MS Entropy package, you can download the code from `MS Entropy Github repository <https://github.com/YuanyueLi/MSEntropy>`_.
+If you encounter any issues, queries or need support, don't hesitate to contact :email:`Yuanyue Li <liyuanyue@gmail.com>`
 
-You can find the documentation of this package at `Read the Docs <https://msentropy.readthedocs.io>`_.
+This package comprises the following modules:
+
+1.  **Classical entropy calculation functions:** These functions are ideal for calculating the classical spectral entropy and entropy similarity for a small set of spectrum pairs.
+
+3.  **Flash Entropy Search Algorithm Functions:** If your task involves searching spectra against a large spectral library, this algorithm will significantly improve the speed of the search process.
+
+
+For a comprehensive understanding of the package, refer to our documentation hosted on `Read the Docs <https://msentropy.readthedocs.io>`_.
+Additionally, you may find practical examples in the `examples <https://github.com/YuanyueLi/MSEntropy/tree/main/examples>`_ folder on our Github repository.
 
-You can also find some examples in the `examples <https://github.com/YuanyueLi/MSEntropy/tree/main/examples>`_ folder.
