 # PgExport
 
-CLI for exporting PostgreSQL database dump to FTP.
+CLI for creating and exporting PostgreSQL dumps to FTP.
 
 Can be used for backups or synchronizing databases between production and development environments.
 
-Configurable by ENV variables and (partially) by command line options.
+Example:
 
+    pg_export --database database_name -keep 5
+    
+Above command will perform database dump, gzip it, upload it to FTP and remove old dumps from FTP, keeping newest 5.
+
+FTP connection params are configured by env variables.
+
+Features:
+
+- uses shell command pg_dump
+- no external gem dependencies
+- uses ruby tempfiles, so local dumps are garbage collected automatically
+
