-OpenShift CLI for CI/CD
-=======================
+# k8s-deploy-tools
 
-This [Openshift command line tool](https://docs.openshift.com/enterprise/3.0/cli_reference/get_started_cli.html) docker
-image ships `oc` and includes `gettext` so you can use `envsubst` to substitute
-environment variables in your CI/CD pipeline, for example using in
-[Jenkins](https://jenkins.io/) or a job in [GitLab CI .gitlab-ci.yml file](https://docs.gitlab.com/ce/ci/yaml/README.html#gitlab-ci-yml).
+CI/CD deployment tools for Kubernetes
 
-Examples
---------
+## Docker Image
+
+This alpine-based docker image contains next tools:
+
+- [`kubectl`](https://kubernetes.io/docs/reference/kubectl/kubectl/) - Kubernetes CLI
+- [`oc`](https://docs.openshift.com/enterprise/3.0/cli_reference/get_started_cli.html) - OpenShift CLI
+- [`istioctl`](https://istio.io/docs/reference/commands/istioctl/) - Istio cli
+- `gettext` - so you can use `envsubst` to substitute environment variables in your CI/CD pipeline
+
+## Examples
 
 Why should I use `envsubst`? You should never put secrets into your version
 control, so you might want to keep them in secret variables in your CI/CD
@@ -21,49 +25,53 @@ Below I'll show an example of [GitLab CI variables set in the build environment]
 
 Your `app.yaml` could look similar the one below:
 
-    $ cat app.yaml
-    ...
-    - apiVersion: v1
-      kind: DeploymentConfig
-      metadata:
-        labels:
-          app: ${CI_PROJECT_NAME}
-        name: sample
-      spec:
-        replicas: 1
-        selector:
-          app: ${CI_PROJECT_NAME}
-          deployment: ${CI_BUILD_REF_SLUG}
-    ...
+```yaml
+...
+- apiVersion: v1
+  kind: DeploymentConfig
+  metadata:
+    labels:
+      app: ${CI_PROJECT_NAME}

+    replicas: 1
+    selector:
+      app: ${CI_PROJECT_NAME}
+      deployment: ${CI_BUILD_REF_SLUG}
+...
+```
 
 After `cat app.yaml | envsubst > app.yaml` you'll notice the variables have
 been replaced with their actual values:
 
-    $ cat app.yaml
-    ...
-    - apiVersion: v1

-        selector:
-          app: my_awesome_project
-          deployment: f1234d
-    ...
