+# Deployment Guide for Kafka Connect Plugins
+
+This guide walks you through the steps to deploy our Kafka Connect plugins, release a new version of the plugins and how to update that version in kafka-ops.
+
+## Prerequisites
+
+- Ensure you have GitHub [personal access token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/managing-your-personal-access-tokens) with full access to Culture Amp private repos
+
+## Deployment Steps
+
+### 1. Make sure tests, linter and dependencies' vulnerability checks are passing
+
+Run the following commands:
+```
+./gradlew test
+./gradlew lintKotlin
+./gradlew dependencyCheckAnalyze
+```
+
+### 2. Update package version in `build.gradle.kts`
+
+Update this line in the aforementioned file
+```
+// Package version
+version = "X.X.X"
+```
+
+### 3. Create build
+
+This project is built using Gradle. To build the project run:
+```
+./gradlew build
+```
+
+This will create a jar:
+```
+./build/libs/kafka-connect-plugins-${version}.jar
+```
+
+Create [md5sum hash](https://www.md5hashgenerator.com/) by running:
+```
+md5sum kafka-connect-plugins-X.X.X.jar
+```
+
+Save that output because it will be used to update correspondent value in kafka-ops dockerfile [further](#5-update-kafka-connect-plugins-version-in-kafka-ops)
+
+## Releasing a New Version
+
+### 1. Tag the Release
+
+After successful deployment, tag the release using the following commands:
+
+\```bash
+git tag -a vX.X.X -m "Release message"
+\```
+
+Replace `vX.X.X` with your version number and `"Release message"` with your release message.
+
+### 2. Push the tag
+
+Push the tag to the remote repository:
+
+\```bash
+git push origin vX.X.X
+\```
+
+Again, replace `vX.X.X` with your version number.
+
+### 3. Create release in GitHub repo of [kafka-connect-plugins](https://github.com/cultureamp/kafka-connect-plugins/releases/new)
+
+Prepare release notes summarizing the changes in this version. Please note if release contains any breaking changes.
+
+## Continue with the deployment steps
+
+### 4. Merge your PR
+
+As above.
+
+### 5. Update kafka-connect-plugins version in kafka-ops
+
+Create new kafka-ops PR with changes in [containers/connect/Dockerfile](https://github.com/cultureamp/kafka-ops/blob/main/containers/connect/Dockerfile). Those changes should include: `CA_PLUGINS_VERSION` env version bump and CA_PLUGINS_MD5SUM env should now include that md5sum hash we generated [earlier](#3-create-build)
+
+### 6. Merge kafka-ops PR
+
+As above.
+
+### 7. Deploy kafka-ops-platform-cluster and kafka-ops-platform-services in  [kafka-ops-infrastructure](https://buildkite.com/culture-amp/kafka-ops-infrastructure/)
+
+Merge of the kafka-ops PR in the previous step will kick-off the pipeline, however you will need to manually deploy master in the following order:
+
+1. Find the branch for the kafka-ops PR and deploy it to `development-us` env
+2. Deploy to `Production-US`
+3. Deploy to `Production-EU`
+4. Deploy to `Staging-US`
+
+### 8. Post-deploy steps
+
+Verify cluster health by looking at the [Kafka Cluster](https://app.datadoghq.com/dashboard/nu9-eun-dpj/kafka-cluster-overview?refresh_mode=sliding&from_ts=1694325305136&to_ts=1696917305136&live=true) and [Connect Cluster](https://app.datadoghq.com/dashboard/nny-trn-iq6/kafka-connect-summary-v2?refresh_mode=sliding&from_ts=1696312530072&to_ts=1696917330072&live=true) Dashboards and announce the release in #kafka_announcements channel
