+## Relevant Note :warning::warning:
+We are excited to announce that we have created a new package called [izari-filecoin :link:](https://github.com/zondax/izari-filecoin), 
+which will be the successor to filecoin-signing-tools. Izari Filecoin is an advanced and 
+user-friendly package that includes several new features and improvements that were not 
+available in this project. The new package is also better organized and easier to use. 
+While this project will continue to be maintained, no new features will be added to it. 
+Therefore, we strongly recommend that you switch to Izari Filecoin to take advantage of 
+its new features and benefits.
