+## Using Matchkits
+
+While the repository does not contain a direct reference to "matchkits," users can interact with the repository's functionality through the CLI or programmatically. 
+
+For CLI usage, you can execute scripts within the repository. For example, to run a script from the command line, you might use:
+
+```
+php src/Snps/EnsemblRestClient.php --argument1 value1 --argument2 value2
+```
+
+For programmatic access, include and utilize classes within your PHP scripts. Here's a simple example:
+
+```php
+require_once 'src/Snps/EnsemblRestClient.php';
+$ensemblClient = new Dna\Snps\EnsemblRestClient();
+$result = $ensemblClient->someMethod();
+```
+
+Explore the `src/Snps/` directory for more scripts and classes that can be used from the CLI or programmatically.
