 The config is a large dictionary. First keys within the dictionary are Stack Names. The global Environment Parameters is a common ground to deduplicate parameter entries that are used in each Stack. Stack parameters overwrite global parameters. 
+When deployer is run, it creates a DynamoDB Table called CloudFormation-Deployer if it does not already exist. The stack configuration in the config file is saved into DynamoDB, and any future changes result in a new entry with an updated timestamp. 
 
 ## Required
 The following are required for each stack, they can be specified specifically to the stack or in the global config.

+Parameters can be overridden from the command line in several different ways. 
+
+The first (which takes precedence) is the -P option. Parameters can be specified in the following form:
+```
+deployer -P 'Param1=Value1'
+``` 
+deployer will set the value of parameter 'Param1' to 'Value1', even if it is also specified in the config file. -P can be specified multiple times for multiple parameters
+
+The second is the -J option. Parameters can be specified in the following form:
+```
+deployer -J '{"Param1":"Value1"}'
+```
+This option allows the user to specify multiple parameter values as a single JSON object. This will override parameters of the same name as those specified in the config file as well.
+
+It is important to note that since a stack's configuration is saved in the DynamoDB state table, specifying these overrides without sending a config file will use the existing configuration for the stack retrieved from the table, but with the overridden parameter values swapped in.
+If it is desirable to send a config file to update some of the parameter values but keep some of the existing values from the previous configuration, it can be done like this:
+```
+    parameters:
+      Monitoring: 'True'
+      NginxAMI:
+        UsePreviousValue: True
+      NginxInstanceType: t2.medium
+```
+Notice that for the NginxAMI parameter, the value is now a dictionary instead of a string, and the UsePreviousValue key is set to True. This indicates to deployer to use the existing value in the configuration for the NginxAMI parameter.
+
+
 ## Lookup Parameters
 
 These are parameters that can be pulled from another stack's output. `deployer` tolerates but logs parameters that exist within the configuration but do not exist within the template.

 ```
 
+## Versions
+There are several command line options that allow the user to view and set the configuration based on version number.
+
+When a new configuration is saved automatically to the DynamoDB table, a version number is generated and assigned to it. These versions can be viewed like this:
+```
+./deployer -s <Stack Name> --config-version list
+```
+This will output a list of config version numbers and creation timestamps. Viewing a specific configuration based on the number can be done like this:
+```
+./deployer -s MyStack --config-version get --config-version-number 1
+```
+In the above example, the output will return the configuration for stack MyStack with the version number 1, the original configuration for the stack. We can then effectively roll back to that configuration with this command:
+```
+./deployer -s MyStack --config-version set --config-version-number 1
+```
+This will set the configuration for MyStack back to version 1, reverting the values for parameters, tags, etc.  
+
+## Exports
+The configuration for a stack can be exported to a file as well. Two formats are supported, JSON and YAML. An example for each is shown here:
+```
+./deployer -s MyStack --export-yaml ../mystack-config.yaml
+./deployer -s MyStack --export-json configs/mystack-config.json

 You can add your own templates under the `cloudformation` directory to deploy your own stacks. Each stack will also need an entry in your deployer config file to specify which directories should be uploaded, the name of the stack, and any required parameters.

+# Upgrade path to 1.0.0
+
+A breaking change is made in the 1.0.0 release. The stack_name attribute in the stack configuration is now deprecated. The resulting CloudFormation stack that is created is now the name of the stack definition. For example, consider the following stack definition:
+
+```
+deployer:
+  stack_name: shared-deployer
+  template: cloudformation/deployer/top.yaml
+  parameters: 
+    Environment: Something
+```
+
+In previous versions, the CloudFormation stack that gets deployed from this is called `shared-deployer`. In 1.0.0+, the CloudFormation stack that gets deployed is called `deployer`. 
+
+This means that for existing configurations, the top level stack definition name must be changed to match the stack_name attribute, like this:
+
+```
+shared-deployer:
+  stack_name: shared-deployer
