 # 3rd
-A script to automate the "off-site copy" in the 3-2-1 Backup strategy with encryption, uploading to AWS S3, and independent definition of compression method and [temporary] archive storage locations for uploading large archives to S3, with support for independent configurations for subdirectories as well.
+A script to automate the 3rd "off-site copy" step in the 3-2-1 Backup strategy. Each directory have independent configuration of compression level, encryption password, AWS S3 destination, and temporary storage location while being uploaded to S3. 
 
 This script is a wrapper for the AWS CLI `aws` and the 7zip CLI `7z` and is meant to be run on Linux. Other operating systems are untested.
 
-## Key features
-- Archive encryption before uploading to AWS S3.
-- Independent compression level, archive location, S3 storage location, for directories and subdirectories.
-
 # Installation
 Make sure you have the following prerequisites before starting:
-- Python 3 installed.
-- The [7zip CLI](https://www.7-zip.org/download.html) installed.
-- The [AWS CLI](https://aws.amazon.com/cli/) installed and configured with write access to your target bucket.
