+> **WARNING:** As a user of Reloader there is no need to build containers, these are freely available here: https://hub.docker.com/r/stakater/reloader/
+
+Multi-architecture approach is based on original work by @mdh02038: https://github.com/mdh02038/Reloader
+
+Images tested on linux/arm, linux/arm64 and linux/amd64.
+
+# Install Pre-Reqs
+The build environment requires the following packages (tested on Ubuntu 20.04):
+* golang
+* make
+* qemu (for arm, arm64 etc. emulation)
+* binfmt-support
+* Docker engine
+
+## Docker
+Follow instructions here: https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository
+
+Once installed, enable the experimental CLI:
+```
+export DOCKER_CLI_EXPERIMENTAL=enabled
+```
+Login, to enable publishing of packages:
+```
+sudo docker login
+```
+## Remaining Pre-Reqs
+Remaining Pre-Reqs can be installed via:
+```
+sudo apt install golang make qemu-user-static binfmt-support -y

+# Publish Multi-Architecture Image
+To build/ publish multi-arch Docker images clone repository and execute from repository root:

+# Helm2 to Helm3 Migration
+
+Follow below mentioned instructions to migrate reloader from Helm2 to Helm3
+
+## Instrcutions:
+
+There are 3 steps involved in migrating the reloader from Helm2 to Helm3.
+
+### Step 1:
+Install the helm-2to3 plugin
+
+```bash
+helm3 plugin install https://github.com/helm/helm-2to3
+
+helm3 2to3 convert <release-name>
+
+helm3 2to3 cleanup --release-cleanup --skip-confirmation
+```
+
+### Step 2:
+Add the following Helm3 labels and annotations on reloader resources.
+
+Label:
+
+```yaml
+app.kubernetes.io/managed-by=Helm
+```
+Annotations:
+```yaml
+meta.helm.sh/release-name=<release-name>
+meta.helm.sh/release-namespace=<namespace>
+```
+
+For example, to label and annotate the ClusterRoleBinding and ClusterRole:
+
+```bash
+KIND=ClusterRoleBinding
+NAME=reloader-reloader-role-binding
+RELEASE=reloader
+NAMESPACE=kube-system
+kubectl annotate $KIND $NAME meta.helm.sh/release-name=$RELEASE
+kubectl annotate $KIND $NAME meta.helm.sh/release-namespace=$NAMESPACE
+kubectl label $KIND $NAME app.kubernetes.io/managed-by=Helm
+
+KIND=ClusterRole
+NAME=reloader-reloader-role
+RELEASE=reloader
+NAMESPACE=kube-system
+kubectl annotate $KIND $NAME meta.helm.sh/release-name=$RELEASE
+kubectl annotate $KIND $NAME meta.helm.sh/release-namespace=$NAMESPACE
+kubectl label $KIND $NAME app.kubernetes.io/managed-by=Helm
+```
+
+### Step 3:
+Upgrade to desired version
+```bash
+helm3 repo add stakater https://stakater.github.io/stakater-charts
+
+helm3 repo update
+
+helm3 upgrade <release-name> stakater/reloader --version=v0.0.72
+```
