 ## Using Private Registries
+Private registries allow us to have repositories to hold containers that need to be private.
+Private registries can be added in the UI and images in the registry can be used
+while creating workloads. Registry can be added by providing a name, specifying
+the scope and credentials for the chosen repositry. The scope of the registry can 
+be the one which is available to all namespaces or which is available to a 
+single namespace. 
+
+In the UI,   
+1. Click on 'Add registry'  
+2. Provide a name  
+3. Choose the scope of the registry    
+4. Choose the Address [DockerHub, Quay.io, Custom]   
+5. Provide credentials of the registry chosen   
+6. Click 'Save'  
+
+Once a registry is added in rancher, the images in the registry can be chosen to
+create a workload
+
+a. From the workloads section, click on deploy a workload  
+b. Provide an image which is in the registry and choose the namespace    
+   Ex: quay.io/username/testubuntu   
+c. Click on 'Launch'. The workload should get deployed successfully

 ## Adding a Secret
 
-Coming Soon
+Secrets are used to hold sensitive information such as passwords.
+Secret can be created in rancher by providing a name along with a keyvalue pair. 
+
+The scope of the secret can be the one which is available to all namespaces or
+which is available to a single namespace. 
+A secret which is created as available to all namespaces can be used to create 
+a workload in any namespace
+A secret which is created as available to a single namespace can be used to 
+create to a workload in that single namespace
+
+
+In the UI,   
+1. Click on 'Add secret'   
+2. Provide a name     
+3. Choose the scope of the secret     
+4. Fill in the key value pair     
+5. Click 'Save'     
+
+Once a secret is created, it can be used in a workload. 
+A secret can be used in a workload in two ways:
+
+1. A workload can be created by using secret as a volume   
+
+a. From the workloads section, click on 'Deploy'    
+b. Provide a docker image and choose the namespace  
+c. Click on volumes   
+d. Provide a volume name and default mode   
+e. Choose a secret which has been added   
+f. Add a mount point (Eg: /test) and subpath if required   
+g. Launch the workload   
+
+
+Once the workload is deployed, right click on the workload and execute the shell.
+In the mount point provided while creating the workload, the secret keys can be
+seen as files. The contents of the file will be the value of the secret
+
+2. A workload can be created by using secret as an env variable
+
+a. From the workloads section, click on 'Deploy'   
+b. Provide a docker image and choose the namespace   
+c. Click on 'Environment variables' and 'add from source'
+d. Choose the type secret, source and keys. All keys or specific keys can be chosen   
+e. Prefix or alias can also be provided   
+g. Launch the workload
