 The Zowe launcher is a part of the Zowe server architecture that was added as an optional program for HA/FT usage in v1.
 In v2, the Zowe laucher became the sole way to start the Zowe servers.
 The launcher's purpose is to start, restart, and stop each Zowe server component which has a `start` command,

 ## Current features
 * Stopping Zowe using the conventional `P` operator command
-* Ability to handle modify commands
+* Ability to handle `MODIFY` commands
 * Stopping and starting specific Zowe components without restarting the entire Zowe
 
 ## Future features
 * Issuing WTOs indicating the start and termination of specific components (this should simplify the integration with z/OS automation)
-* Passing modify commands to Zowe components
+* Passing `MODIFY` commands to Zowe components
 * Clean termination of the components in case if the launcher gets cancelled

+## Architecture
+
+The launcher is a z/OS program which utilizes [configmgr](https://github.com/zowe/zowe-common-c/blob/v3.x/staging/c/configmgr.c) to read the Zowe config in order to determine which components to start, and then prepares Zowe to run, starts the components, and manages their unix processes.
