 Extensibility API for Zowe Explorer is a collection of APIs that can be used to extend the [Zowe Explorer](https://github.com/zowe/zowe-explorer-vscode) VS Code extension with alternative z/OS interaction protocols and new capabilities.
 
-The current state of this API is experimental, but the goal is provide a stabilized version that can be used for Zowe Conformance certifications in the future. See this issue for more details: <https://github.com/zowe/zowe-explorer-vscode/issues/837>.
+The API is used by extenders of the Zowe Explorer VS Code extension, including the [IBM z/OS FTP for Zowe Explorer](https://github.com/zowe/zowe-explorer-vscode/tree/main/packages/zowe-explorer-ftp-extension) and [IBM CICS for Zowe Explorer](https://github.com/zowe/cics-for-zowe-client/tree/main/packages/vsce) VS Code extensions, as well as several commercial extensions.
 
-However, the current API is being used by other extensions already, such as for Zowe Explorer with the [Zowe Explorer FTP Extension](../zowe-explorer-ftp-extension) that you can find in this same Git repository, as well as for commercial extensions maintained by Zowe's contributors and available on their company websites.

-Currently, the API is organized into two modules, which both are rolled up into the top-level `index.ts` file for convenient access.

 - `/profiles`: Provides access to common Zowe CLI profile management APIs, as well as abstractions for providing alternative z/OS interactions that use protocols other than z/OSMF, based on alternative Zowe CLI profile types.
 - `/tree`: Provides abstractions for accessing and extending the Zowe Explorer VS Code tree views.

-The main API provided by the `/profiles` module is called `ZoweExplorerApi`. It defines a namespace for interfaces for implementing access to z/OS MVS, USS, and JES. You can see that the Zowe Explorer FTP Extension provides such an alternative implementation for USS using the FTP protocol in [packages/zowe-explorer-ftp-extension/src/ZoweExplorerFtpApi.ts](../zowe-explorer-ftp-extension/src/ZoweExplorerFtpApi.ts).

-Zowe Explorer itself exports a `IApiRegisterClient` object that can be used for an alternative implementation to be registered with Zowe Explorer. You can find an example for doing this in [packages/zowe-explorer-ftp-extension/src/extension.ts](../zowe-explorer-ftp-extension/src/extension.ts).

+- **Insert/overtype modes**: Visual Studio Code v1.96 introduced the ability to toggle between insert and overtype modes by pressing the `Insert` key. Overtype mode can be helpful when working with data sets and members with fixed record lengths.
