+### TIPS
+If your service is going to run behind nginx or any other proxy in your kubernetes cluster then passing on `proxy-path` variable becomes a must to avoid to avoid errors by webend, by-default it is blank.
+dont add prefix '/' for the path.
+Ex: if your kubernetes ingress piece of routing yaml is like this
+```yaml
+...
+spec:
+  rules:
+  - host: api.myhost.mysite.com
+    http:
+      paths:
+      - backend:
+          serviceName: transfersh
+          servicePort: 80
+        path: /filemanager
+...
+```
+=> PROXY_PATH arg must be set to 'filemanager' & not /filemanager.
 
-##  HOW TO? Kubernetes helm chart
 
+##  Helm chart
+```sh
 cd charts/transfersh
 helm install --debug --name=transfersh transfersh/
+```
+
+### NOTE:
+- All variables are same as mentioned [here](https://github.com/dutchcoders/transfer.sh#usage-1) with below mentioned operations done on them.
+- Operations applied on Usage params
+  - UPPERCASING them
+  - replacing hyphens by underscores
+- Ex: http-auth-user => HTTP_AUTH_USER, s3-region => S3_REGION
+- Every arg needed by the transfer.sh binary is passed via environment variable in deployment yaml injected via the secrets/configmaps at runtime.
+- Deployment fails in case of non-availability of secrets/configMaps in your cluster, as selected via values.yaml file.
