+Secrets management for today's decentralized world of people, services and devices.
+
+Use Polykey to share secrets (passwords, keys, tokens and certificates) with people, between teams, and across machine infrastructure
+
+Polykey is an open-source peer to peer decentralized application for secrets management. It is intended to be used by both humans and machines. It synthesizes a unified workflow between interactive password management and infrastructure key management.
+
+You have complete end-to-end control and privacy over your secrets, with no third-party data collection.
+
+Polykey runs on distributed keynodes referred to as "nodes". Any computing system can run multiple keynodes. Each node manages one or more vaults which are encrypted filesystems with automatic version history. Vaults are shared between the nodes.
 
 This is the core library for running PolyKey. It provides a CLI `polykey` or `pk` for interacting with the PolyKey system.
 
 For tutorials, how-to guides, reference and theory, see the [wiki](https://github.com/MatrixAI/Polykey/wiki).

 ## Deployment
 
-### Deploying to AWS ECS:
+Image deployments are done automatically through the CI/CD. However manual scripts are available below for deployment.
+
+### Deploying to AWS ECR:
 
-First login to AWS ECR:
+#### Using skopeo
 
 ```sh

+# This will push both the default image tag and the latest tag
+./scripts/deploy-image.sh "$build" "$tag" "$registry_image"
 ```
 
-Proceed to build the container image and upload it:
+#### Using docker
 
 ```sh
-repo="015248367786.dkr.ecr.ap-southeast-2.amazonaws.com" && \
