+
+First off, thanks for taking the time to contribute! ❤️
+
+> And if you like the project, but just don't have time to contribute, that's fine. There are other easy ways to support the project and show your appreciation, which we would also be very happy about:
+> - Star the project
+> - Tell a friend about it
+> - Refer this project in your project's readme
+> - Mention the project at local meetups and tell your friends/colleagues
+
+## I Have a Question
+
+> If you want to ask a question, we assume that you have read the available [Documentation](https://smarty-php.github.io/smarty).
+
+Before you ask a question, it is best to search for existing [Issues](https://github.com/smarty-php/smarty/issues) that might help you. 
+In case you have found a suitable issue and still need clarification, you can write your question in this issue. 
+It is also advisable to search the internet for answers first.
+
+If you then still feel the need to ask a question and need clarification, we recommend the following:
+
+- [Open an Issue](https://github.com/smarty-php/smarty/issues/new).
+- Provide as much context as you can about what you're running into.
+- Provide Smarty and PHP versions
+
+We will then take care of the issue as soon as possible.
+
+## I Want To Contribute
+
+> ### Legal Notice
+> When contributing to this project, you must agree that you have authored 100% of the content, 
+> that you have the necessary rights to the content and that the content you contribute may be provided under the project license.
+
+### Reporting Bugs
+
+#### Before Submitting a Bug Report
+
+A good bug report shouldn't leave others needing to chase you up for more information. Therefore, we ask you to 
+investigate carefully, collect information and describe the issue in detail in your report. Please complete the 
+following steps in advance to help us fix any potential bug as fast as possible.
+
+- Make sure that you are using the latest version.
+- Determine if your bug is really a bug and not an error on your side. (Make sure that you have read the [documentation](https://smarty-php.github.io/smarty). If you are looking for support, you might want to check [this section](#i-have-a-question)).
+- To see if other users have experienced (and potentially already solved) the same issue you are having, check if there is not already a bug report existing for your bug or error in the [bug tracker](https://github.com/smarty-php/smarty/issues?q=label%3Abug).
+- Also make sure to search the internet (including Stack Overflow) to see if users outside of the GitHub community have discussed the issue.
+- Collect information about the bug:
+  - For an Exception: please provide the Stack trace
+  - OS (Windows, Linux, macOS)
+  - PHP version
+  - Smarty version
+  - A minimal snippet of (your) code that triggers the bug
+  - Expected output versus actual output
+  - Can you reliably reproduce the issue? And can you also reproduce it with older versions?
+
+#### How Do I Submit a Good Bug Report?
+
+> You must never report security related issues, vulnerabilities or bugs including sensitive information to the issue tracker, or elsewhere in public. 
+> For sensitive bugs, please see [SECURITY.md](SECURITY.md).
+
+We use GitHub issues to track bugs and errors. If you run into an issue with the project:
+
+- Open an [Issue](https://github.com/smarty-php/smarty/issues/new). (Since we can't be sure at this point whether it is a bug or not, we ask you not to talk about a bug yet and not to label the issue.)
+- Explain the behavior you would expect and the actual behavior.
+- Please provide as much context as possible and describe the *reproduction steps* that someone else can follow to recreate the issue on their own. This usually includes your code. For good bug reports you should isolate the problem and create a reduced test case.
+- Provide the information you collected in the previous section.
+
+Once it's filed:
+
+- The project team will label the issue accordingly.
+- A team member will try to reproduce the issue with your provided steps. If there are no reproduction steps or no obvious way to reproduce the issue, the team will ask you for those steps and mark the issue as `needs-repro`. Bugs with the `needs-repro` tag will not be addressed until they are reproduced.
+- If the team is able to reproduce the issue, it will be marked `needs-fix`, as well as possibly other tags (such as `critical`), and the issue will be left to be implemented by someone.
+
+
+
+### Suggesting Enhancements
+
+This section guides you through submitting an enhancement suggestion for CONTRIBUTING.md, **including completely new features and minor improvements to existing functionality**. Following these guidelines will help maintainers and the community to understand your suggestion and find related suggestions.
+
+
+#### Before Submitting an Enhancement
+
+- Make sure that you are using the latest version.
+- Read the [documentation](https://smarty-php.github.io/smarty) carefully and find out if the functionality is already covered, maybe by an individual configuration.
+- Perform a [search](https://github.com/smarty-php/smarty/issues) to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
+- Find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. Keep in mind that we want features that will be useful to the majority of our users and not just a small subset. If you're just targeting a minority of users, consider writing an add-on/plugin library.
+
+
+#### How Do I Submit a Good Enhancement Suggestion?
+
+Enhancement suggestions are tracked as [GitHub issues](https://github.com/smarty-php/smarty/issues).
+
+- Use a **clear and descriptive title** for the issue to identify the suggestion.
+- Provide a **step-by-step description of the suggested enhancement** in as many details as possible.
+- **Describe the current behavior** and **explain which behavior you expected to see instead** and why. At this point you can also tell which alternatives do not work for you.
+- You may want to **include screenshots and animated GIFs** which help you demonstrate the steps or point out the part which the suggestion is related to. You can use [this tool](https://www.cockos.com/licecap/) to record GIFs on macOS and Windows, and [this tool](https://github.com/colinkeenan/silentcast) or [this tool](https://github.com/GNOME/byzanz) on Linux.
+- **Explain why this enhancement would be useful** to most CONTRIBUTING.md users. You may also want to point out the other projects that solved it better and which could serve as inspiration.
+
+
+### Improving The Documentation
+
+The [docs](docs/index.md) are written in markdown, configured in [mkdocs.yml](mkdocs.yml) and published 
+to [GitHub pages](https://smarty-php.github.io/smarty) using [mkdocs](https://www.mkdocs.org/) and [mike](https://github.com/jimporter/mike).
+
+To preview the docs while you are writing, run:
+```bash
+mkdocs serve
+```
+This should launch a local web server and give you a link to open in your browser.
+
+When you are finished, commit your changes and provide a [Pull Request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request).
+
+#### Publishing the docs
+If you are a maintainer, you can publish the document using [mike](https://github.com/jimporter/mike). Make sure you provide the correct version.
+
+```bash
+mike deploy 5.x
+```

+## Enabling auto-escaping
+By default, Smarty does not escape anything you render in your templates. If you use
+Smarty to render a HTML-page, this means that you will have to make sure that you do
+not render any characters that have a special meaning in HTML, such as `&`, `<` and `>`,
+or apply the [escape modifier](../designers/language-modifiers/language-modifier-escape.md) 
+to anything you want to render.
+
+If you forget to do so, you may break your HTML page, or even create a vulnerability for 
+attacks known as [XSS or Cross Site Scripting](https://cheatsheetseries.owasp.org/cheatsheets/Cross_Site_Scripting_Prevention_Cheat_Sheet.html).
+
+Luckily, you can tell Smarty to automatically apply the escape modifier to any dynamic part of your template.
+It's like Smarty magically adds `|escape` to every variable you use on a web page.
+
+Enable auto-escaping for HTML as follows:
+```php
+$smarty->setEscapeHtml(true);
+```
+

+## Using modifiers in expressions
+
+Modifiers can also be used in expressions. For example, you can use the [isset modifier](./language-modifier-isset.md)
+to test if a variable holds a value different from null.
+
+```smarty
+{if $varA|isset}
+    <b>variable A is set</b>
+{/if}
+```
+
+You can also use modifiers in expressions in a PHP-style syntax:
+
+```smarty
+{if isset($varA)}
+    <b>variable A is set</b>
+{/if}
+```

+# Upgrading from an older version
+
+## Upgrading from v4 to v5
+
+Smarty 5 adds support for PHP8.2 and drops support for PHP7.1. Smarty also adds support for new features
+such as the ternary operator (`{$test ? $a : $b}` and `{$var ?: $value_if_falsy}`), the null coalescing operator (`{$var ?? $value_if_null}`) 
+and positional parameters for custom tags.
+Smarty 5 also has a brand-new extension architecture that allows you to write neat extension packs.
+
+### Namespaces
+All Smarty code has been moved into the `\Smarty` namespace. This reduces
+the chance of conflicts with other (your) code.
+
+For simple use-cases, you only need to add `use Smarty\Smarty;` to your script and everything will work. 
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->display('homepage.tpl');
+```
+For more information, see [getting started](getting-started.md).
+
+If you extend Smarty or use Smarty plug-ins, please review your code to see if they assume specific class or method names.
+E.g.: `Smarty_Internal_Template` is now `\Smarty\Template\`, `SmartyException` is now `\Smarty\Exception`.
+
+### Variable scope bubbling
+Template variable scope bubbling has been simplified and made more consistent. The global scope now equals the Smarty 
+scope in order to avoid global state side effects. Please read the [documentation on language variable scope](designers/language-variables/language-variable-scopes.md)
+for more details.
+
+Also, `{config_load}` no longer has a `scope` parameter, which means you can no longer load config
+from inside your template into the global scope (again, to avoid global state side effects). If you 
+need to set global config, use the [configLoad API method](api/variables/config-files.md) from your PHP code.
+
+### Using native PHP-functions or userland functions in your templates
+You can no longer use native PHP-functions or userland functions in your templates without registering them. 
+If you need a function in your templates, register it first.
+
+The easiest way to do so is as follows:
+```php
+// native PHP functions used as modifiers need to be registered
+$smarty->registerPlugin('modifier', 'substr', 'substr');
+
+// userland PHP functions used as modifiers need to be registered
+$smarty->registerPlugin('modifier', 'my_special_func', 'my_special_func');
+```
+
+But you may want to consider writing a proper [extension](api/extending/extensions.md).
+
+### Removed undocumented tags
+
+Smarty 4 still supported some tags that have been carried over from previous version, but have never been documented.
+
+- `{block_parent}` should be replaced with `{$smarty.block.parent}`
+- `{parent}` should be replaced with `{$smarty.block.parent}`
+- `{block_child}` should be replaced with `{$smarty.block.child}`
+- `{child}` should be replaced with `{$smarty.block.child}`
+
+- `{make_nocache}` is no longer supported
+- `{insert}` is no longer supported
+
+### Removed Smarty API properties
+
+In Smarty 4, you could make many configuration changes by directly accessing public properties on the Smarty object in PHP.
+In many cases, these properties have been made private, and you should now use the appropriate setter method:
+
+- `$smarty->left_delimiter` should be replaced with `$smarty->getLeftDelimiter()`/`$smarty->setLeftDelimiter()`
+- `$smarty->right_delimiter` should be replaced with `$smarty->getRightDelimiter()`/`$smarty->setRightDelimiter()`
+- `$smarty->autoload_filters` should be replaced with `$smarty->registerFilter()`
+- `$smarty->template_dir` should be replaced with `$smarty->setTemplateDir()`
+- `$smarty->cache_dir` should be replaced with `$smarty->setCacheDir()`
+- `$smarty->compile_dir` should be replaced with `$smarty->setCompileDir()`
+
+Other public properties have been removed altogether, and you should no longer access them:
+
+- `$smarty->_current_file`
+- `$smarty->allow_ambiguous_resources` (ambiguous resources handlers should still work)
+- `$smarty->registered_filters`
+- `$smarty->direct_access_security`
+- `$smarty->trusted_dir`
+- `$smarty->allow_php_templates`
+- `$smarty->php_functions`
+- `$smarty->php_modifiers`
+
+### Backwards incompatible changes to custom plugins
+
+We have dropped support for `$smarty->plugins_dir` and `$smarty->use_include_path`.
+Use `$smarty->addPluginsDir()` or consider writing a proper [extension](api/extending/extensions.md).
+
+The 'insert' plugin type is no longer supported.
+
+The `$cache_attrs` parameter for registered plugins is no longer supported.
+
+### Removed Smarty API methods
+
+Search your code for the following changes:
+
+- `$smarty->getTags()` is no longer supported
+- `$smarty->appendByRef()` should be replaced with `$smarty->append()`
+- `$smarty->assignByRef()` should be replaced with `$smarty->assign()`
+- `$smarty->loadPlugin()` should be replaced with `$smarty->registerPlugin()`
+
+### Removed PHP constants
+
+The following constants have been removed to prevent global side effects.
+
+- `SMARTY_DIR`
+- `SMARTY_SYSPLUGINS_DIR`
+- `SMARTY_PLUGINS_DIR`
+- `SMARTY_MBSTRING`
+- `SMARTY_HELPER_FUNCTIONS_LOADED`
+
+### Other changes
+
+- Smarty now always runs in multibyte mode. Make sure you use the [PHP multibyte extension](https://www.php.net/manual/en/book.mbstring.php) in production for optimal performance.
+- Generated `<script>` tags lo longer have deprecated `type="text/javascript"` or `language="Javascript"` attributes
+- Smarty will throw a compiler exception instead of silently ignoring a modifier on a function call, like this: `{include|dot:"x-template-id" file="included.dot.tpl"}`
+- The ::getFile() method of a CompilerException will now return the full path of the template being compiled, if possible. This used to be 'file:relative_dir/filename.tpl'.
+
+## Upgrading from v3 to v4
+
+Smarty 4 is mostly identical to Smarty 3. Most notably, it adds support for PHP8 and drops support for PHP7.0 and below.
+Additionally, some deprecated features that have long been discouraged have been dropped from the language.
+
+### Muting PHP8 warnings
+If you simultaneously upgrade Smarty to v4 van PHP to v8, you may notice your error logs filling up with warnings about undefined or null template vars 
+due to a change in how PHP handles these. This may be helpful to spot errors, but if you find this annoying, you can use
+`$smarty->muteUndefinedOrNullWarnings()` to make Smarty convert these warnings into notices.
+
+### ASP tags
+You can no longer user ASP-style tags like `<% %>` and `<%= %>` in your templates.
+Replace them with `{...}` tags.
+
+### SmartyBC
+Check your codebase for `SmartyBC`.
+We have dropped deprecated API calls that where only accessible through the SmartyBC class.
+
+### No more embedded PHP
+We have completely dropped support for `{php}` and `{include_php}` tags and embedded PHP in templates.
+Check your templates for this, and rewrite any embedded PHP blocks, by moving logic to your PHP files or by
+creating a [custom tag](./api/extending/tags.md). 
+
+### Other changes
+
+Search your code for the following changes: 
+
+- `SMARTY_RESOURCE_CHAR_SET` and `SMARTY_RESOURCE_DATE_FORMAT` constants have been removed
+- `Smarty::muteExpectedErrors` and `Smarty::unmuteExpectedErrors` API methods have been removed
+- `Smarty::getVariable` method has been removed. Use [Smarty::getTemplateVars](designers/language-builtin-functions/language-function-assign.md) instead.
+- [Smarty::registerResource](api/resources.md) no longer accepts an array of callback functions
