 # summary
 
-Enable a sourceBehaviorOption in sfdx-project.json and update your project source to use it.
+Enable a behavior of your project source files, and then update your Salesforce DX project to implement the behavior.
 
 # description
 
-Makes local changes to your project based on the chosen sourceBehaviorOption.
+Specifically, this command updates the "sourceBehaviorOption" option in the "sfdx-project.json" file and then converts the associated local source files in your project as needed.
+
+For example, run this command with the "--behavior decomposePermissionSet" flag to start decomposing permission sets when you deploy or retrieve them. Decomposing means breaking up the monolithic metadata API format XML file that corresponds to a metadata component into smaller XML files and directories based on its subtypes. Permission sets are not decomposed by default; you must opt-in to start decomposing them by using this command. When the command finishes, your "sfdx-project.json" file is updated to always decompose permission sets, and the existing permission set files in your local package directories are converted into the new decomposed format. You run this command only once for a given behavior change.
+
+For more information about the possible values for the --behavior flag, see the "sourceBehaviorOptions" section in the https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_ws_config.htm topic.
 
 # flags.behavior.summary
 
-Which sourceBehaviorOption to enable.
+Behavior to enable; the values correspond to the possible values of the "sourceBehaviorOption" option in the "sfdx-project.json" file.
