+# Deprecation notice
+
+This project is deprecated in favor of `apt-file` utility. Package `whatprovides` and database file will be removed.
+
+You can install `apt-file` package with next command:
+```
+pkg install apt-file
+```
+
+Depending on Termux version (< 0.118), you may need to fix permission of one file in $PREFIX (known issue):
+```
+chmod +x $PREFIX/lib/apt/apt-helper
+```
+
+Usage example:
+```
+~ $ apt-file update
+~ $ apt-file list termux-tools

 * search for files. Have you ever used `dpkg -S filepath`. 
 Here you need to use like `whatprovides filepath`. 
 You can search for any files which even not exist in your termux.
 it will show you which package provide that file.
