-# Usage
+## Usage
+
+First, determine the paths to your files (datafile & lockfile, see below):
+
+```php
+<?php
+
+require_once('vendor/autoload.php');
+
+use S1SYPHOS\Thx;
+
+$pkgFile = 'path/to/composer.json';                # or 'package.json' for NPM / Yarn
+$lockFile = 'path/to/composer.lock'                # or 'package-lock.json' for NPM / 'yarn.lock' for Yarn
+$cacheDriver = 'file';                             # Optional: Cache driver, see below
+$cacheSettings = ['storage' => '/path/to/cache'];  # Optional: Cache settings, see below
+```
+
+**Note:**
+For available cache drivers & settings, see [here](https://github.com/terrylinooo/simple-cache)!
+
+Passing these options to `Thx::giveBack()` creates an instance:
+
+```php
+$obj = Thx::giveBack($pkgFile, $lockFile, $cacheDriver, $cacheSettings);
+```
+
+.. which you may configure to your liking by using:
+
+- `setTimeout(int $seconds)`
+- `setCacheDuration(int $days)`
+- `setUserAgent(string $userAgent)`
+- `setBlockList(array $blockList)`
+
+```php
+# For example:
+
+$obj->setCacheDuration(7);                    # Cache results for one week
+$obj->setBlockList(['php', 'some/library']);  # Block from being processed
+```
+
+After setting everything up, `spreadLove()` makes some API calls:
+
+- Composer packages @ https://repo.packagist.org
+- Node packages @ https://api.npms.io
+
+```php
+$obj->spreadLove();
+```
+
+Currently there are three methods you can use:
+
+- `data()` returns raw data from lockfile for all used packages
+- `pkgs()` returns processed data for all used packages
+- `packages()` returns the names of all used packages
+
+```php
+# Alternative 1:
+# Process data
+$obj->spreadLove();
+
+# Work with it
+$raw = $obj->data();
+$processed = $obj->pkgs();
+
+# Alternative 2:
+# Since `spreadLove` allows chaining, you could also do it like this:
+$obj->spreadLove()->data();
+
+# The second call provides cached data, no performance penalty there
+$obj->spreadLove()->pkgs();
+```
+
+
