+
+
+## Using helm charts through emcoctl
+
+When you need to use emcoctl for deploying helm
+charts the following steps are required.
+
+1. Make sure that the composite app which you are planning to deploy, the tree structure is as below
+
+```
+
+$  tree collection/app1/
+collection/app1/
+├── helm
+│   └── collectd
+│       ├── Chart.yaml
+│       ├── resources
+│       │   └── collectd.conf
+│       ├── templates
+│       │   ├── configmap.yaml
+│       │   ├── daemonset.yaml
+│       │   ├── _helpers.tpl
+│       │   ├── NOTES.txt
+│       │   └── service.yaml
+│       └── values.yaml
+└── profile
+    ├── manifest.yaml
+    └── override_values.yaml
+
+5 directories, 10 files
+
+$  tree collection/m3db/
+collection/m3db/
+├── helm
+│   └── m3db
+│       ├── Chart.yaml
+│       ├── del.yaml
+│       ├── templates
+│       │   └── m3dbcluster.yaml
+│       └── values.yaml
+└── profile
+    ├── manifest.yaml
+    └── override_values.yaml
+
+4 directories, 6 files
+
+```
+
+### NOTE
+```
+* In the above example, we have a composite app : collection
+The collection composite-app shown has two apps : app1(collectd)
+and m3db
+* Each app has two dirs : a. HELM and b. PROFILE.
+* Helm dir shall have the real helm charts of the app.
+* profile shall have the two files - manifest.yaml and override_values.yaml for creating the customized profile.
+```
+
+### Commands for making the tar files from helm.
+
+```
+    tar -czf collectd.tar.gz -C $test_folder/vnfs/comp-app/collection/app1/helm .
+    tar -czf collectd_profile.tar.gz -C $test_folder/vnfs/comp-app/collection/app1/profile .
+    ----------------------------------------
+    tar -czf m3db.tar.gz -C $test_folder/vnfs/comp-app/collection/m3db/helm .
+    tar -czf m3db_profile.tar.gz -C $test_folder/vnfs/comp-app/collection/m3db/profile .
+```
+
+Once you have generated the tar files, you need to give the path in file which you are applying using the emcoctl. For eg:
+
+```
+#adding collectd app to the composite app
+version: emco/v2
+resourceContext:
+  anchor: projects/proj1/composite-apps/collection-composite-app/v1/apps
+metadata :
+  name: collectd
+  description: "description for app"
+  userData1: test1
+  userData2: test2
+file:
+  /opt/csar/cb009bfe-bbee-11e8-9766-525400435678/collectd.tar.gz
+
+```
+
+```
+#adding collectd app profiles to the composite profile
+version: emco/v2
+resourceContext:
+  anchor: projects/proj1/composite-apps/collection-composite-app/v1/composite-profiles/collection-composite-profile/profiles
+metadata :
+  name: collectd-profile
+  description: test
+  userData1: test1
+  userData2: test2
+spec:
+  app-name: collectd
+file:
+  /opt/csar/cb009bfe-bbee-11e8-9766-525400435678/collectd_profile.tar.gz
+
+```
+
+### Running the emcoctl
+
+```
+* Make sure that the emcoctl is build.You can build it by issuing the 'make' command.
+Dir : $MULTICLOUD-K8s_HOME/src/tools/emcoctl
+```
+* Then run the emcoctl by command:
+```
+./emcoctl --config ./examples/emco-cfg.yaml apply -f ./examples/test.yaml
+
+```
+
+Here, emco-cfg.yaml contains the config/port details of each of the microservices you are using.
+A sample configuration is :
+
+```
+  orchestrator:
+    host: localhost
+    port: 9015
+  clm:
+    host: localhost

+  ncm:
+    host: localhost
+    port: 9016
+  ovnaction:
+    host: localhost
+    port: 9051
+```
