 Alternative setup composer local zip file repot:
 `composer config repositories.composer.egplusww.jp composer http://composer.egplusww.jp`
 
+> [!notice]
+> Requires mbstring extension installed, will not use the symfony/polyfill-mbstring
+
 ## Install package
 
-`composer require egrajp/smarty-extended:^4.3`
+`composer require egrajp/smarty-extended:^5`
 
 ## How to update
 
-1) update the original composer for ^4.3
-2) copy over the src/sysplugins and all base files in src/
-3) check either function.html_checkboxes.php and function.html_options.php have changed
-4) copy src/plugins except the above two files, be sure to keep the block.t.php and function_popup*.php
-5) Create new release version as official relase number
+1) Alternative is to checkout master branch from git
+   1) Located in `Smarty/Smarty-git/src/`
+   2) Run `git pull smarty master`
+2) Copy the `src/` folder as is over the `Smarty/Smarty-Extended/src` folder
+3) From the `update/` folder copy
+   1) copy over the following into `src/BlockHandler/`:
+      1) T.php
+   2) copy over the following into `src/FunctionHandler`:
+      1) Popup.php
+      2) PopupInit.php
+   3) Upate the global `src/Extensions/DefaultExtension.php`:
+      1) `getFunctionHandler`: popup_init, popup
+      2) `getBlockHandler`: t
+   4) check either `src/FunctionHander/HtmlCheckboxes.php`, `src/FunctionHander/HtmlOptions.php` and `src/FunctionHander/HtmlBase.php` have changed
+      1) Update and leep the label/pos changes
+4) Create new release version as official relase number
+
+## Test
+
+After any update run `tools/phpunit` to test the compare output, also a visual check can be done by accessing the `test/` folder
+
+- Translations should work
+- pos/label names for checkbox/options should work
+- get var output should work
+- plugin test load should work
+
+### For intelephense users when phpunit was installed as phar
+
+Intelephense cannot directly access the phar file, if phpunit was installed as a phar file (eg via phive) then the following commands must be used to setup the intelephense parser
+
+In the base folder:
+
+```sh
+php -r "(new Phar('/path/to/phive/folder/.phive/phars/phpunit-X.Y.Z.phar'))->extractTo('tools-libs/phpunit');"
+// Example, must point to the .phar file itself
+php -r "(new Phar('/storage/home/clemens/.phive/phars/phpunit-11.5.46.phar'))->extractTo('tools-libs/phpunit');"
+```
+
+Then open the vscode settings and set for the Folder (if multiple folders are in the workspace) or the Workspace the following setting
+
+```txt
+"intelephense.environment.includePaths": [
+  "/tools-libs/phpunit/"
+]
+```
 
 ## Updated files (different from master)
 
 ### New
 
-`src/plugins/block.t.php`
-`src/plugins/function_popup.php`
-`src/plugins/function_popup.init.php`
+- `src/BlockHandler/T.php`
+- `src/FunctionHandler/Popup.php`
+- `src/FunctionHandler/PopupInit.php`
 
 ### Changed
