-### New ```atInit``` IOC Shell Command Added
+### New `atInit` IOC Shell Command Added
 
-The pull request ```PR #558``` introduces a new IOC shell command `atInit` to EPICS Base, which allows users to schedule arbitrary commands to be executed automatically after the IOC initialization phase (`iocInit`).
+This release incorporates [PR #558](https://github.com/epics-base/epics-base/pull/558) which added a new IOC shell command `atInit`. This command allows startup scripts to schedule arbitrary commands to be executed automatically after the IOC initialization phase (`iocInit`).
 
-The module allows you to write better-structured ioc shell files to include in your startup scripts without tracking where iocInit is located (and how IOC is deployed) e.g.:

+`atInit` allows you to write better-structured IOC shell files to include in your startup scripts without tracking where `iocInit` is located (and how IOC is deployed) e.g.:
+- to achieve the best maintainability (e.g. encapsulation of the context into one file),
 - to improve writing boot sequences,
-- to improve IOC startup flexibility and scripting capabilities.
+- to improve IOC startup flexibility and scripting capabilities,
+- it replaces the community [`afterInit`](https://github.com/paulscherrerinstitute/iocsh_utilities/blob/master/afterInit.c) and [`doAfterIocInit`](https://github.com/epics-modules/std/blob/master/stdApp/src/delayCmd.cpp) IOC shell commands,
+- community usage examples:
+  - [`pf4filters.iocsh`](https://github.com/epics-modules/optics/blob/master/opticsApp/iocsh/pf4filters.iocsh) - enable/disable with a single comment ([full description](https://github.com/epics-base/epics-base/pull/558#issuecomment-2430057167))
+  - [ALS-U autosave managment](https://github.com/epics-base/epics-base/pull/558#issuecomment-2430447220)
 
 #### Features
 
 - Define commands that run after IOC initialization completes.
-- Overwrites ```autosave``` to ensure proper configuration of the required PV.
+- Executes following `iocInit` and `autosave` initialization (important for proper PV configuration).
 - Supports any valid IOC shell command as an argument.
 - Example usages:
   - `atInit "dbpf <PV> <VAL>"`
   - `atInit "date"`
-
-#### Testing
-
-- Unit tests have been added to verify:
-  - Registration and execution of commands scheduled with `atInit`.
-  - Proper handling of empty or invalid commands without crashing the IOC.
-  - Execution order and environment variable effects.
+  - `atInit "dbpf $(P)EvtClkSource-Sel 'Upstream (fanout)'"`
+  - `atInit "dbpf $(P)Enable-Sel Enabled"`
