-Do you maintain [a monorepo](https://tomasvotruba.com/blog/2019/10/28/all-you-always-wanted-to-know-about-monorepo-but-were-afraid-to-ask/) with more packages?
+Do you maintain a monorepo with multiple packages?
 
 **This package has few useful tools, that will make that easier**.
 
 ## Install
 
 ```bash
+# Latest version (PHP 8.2+)
 composer require symplify/monorepo-builder --dev
+
+# For PHP 8.1 (legacy version, no longer maintained)
+composer require "symplify/monorepo-builder:^11.2" --dev
 ```
 
+**Requirements:**
+- PHP 8.2 or higher (for version 12.x)
+
+**For older PHP versions:**
+- Use version 11.x (no longer maintained)
+
 ## Usage
 
 ### 1. Are you New to Monorepo?
 
-The best to lean-in fast is to read basic intro at blog post [All You Always Wanted to Know About Monorepo](https://www.tomasvotruba.com/blog/2019/10/28/all-you-always-wanted-to-know-about-monorepo-but-were-afraid-to-ask/#what-is-monorepo).
-We also made a simple command to make that easy for you:
+If you're new to monorepos, you can start with a basic setup using our initialization command:
 
 ```bash
 vendor/bin/monorepo-builder init
 ```
 
-And the basic setup is done!
+This creates a basic monorepo structure with the necessary configuration files.
+
 
 ### 2. Merge local `composer.json` to the Root One
 
 Merges configured sections to the root `composer.json`, so you can only edit `composer.json` of particular packages and let script to synchronize it.
 
-Sections that are needed for monorepo to work will be merged:
+Sections that will be merged from packages to root:
 
-- 'require'
-- 'require-dev'
-- 'autoload'
-- 'autoload-dev'
-- 'repositories'
-- 'extra'
+- `require` - Dependencies needed by packages
+- `require-dev` - Development dependencies  
+- `autoload` - PSR-4 autoloading configuration
+- `autoload-dev` - Development autoloading configuration
+- `repositories` - Package repositories
+- `extra` - Extra configuration data
+- `provide` - Virtual packages provided
+- `authors` - Package authors information
+- `minimum-stability` - Minimum package stability
+- `prefer-stable` - Prefer stable packages
+- `replace` - Packages replaced by this one

 ### 6. Split Directories to Git Repositories
 
-Thanks to GitHub Actions, this was never simpler to set up. Use [symplify/github-action-monorepo-split](https://github.com/symplify/github-action-monorepo-split).
+You can split packages from your monorepo into separate repositories using GitHub Actions. Use [symplify/github-action-monorepo-split](https://github.com/symplify/github-action-monorepo-split) for this purpose.
 
-How to configure it? See our local setup at [.github/workflows/split_monorepo.yaml](https://github.com/danharrin/monorepo-split-github-action/blob/main/.github/workflows/split.yaml)
