 The easiest way to contribute is to work on a checkout of your own fork.
 When working on the `core` repository, it makes sense to rename your fork to `php-telegram-bot`.
 
-Before you contribute code, please make sure it conforms to the PSR-2 coding standard and that the unit tests still pass.
+Before you contribute code, please make sure it conforms to the PSR-12 coding standard and that the unit tests still pass.
 You can run the following commands to check if everything is ready to submit:
 
-    cd php-telegram-bot
-    composer install
-    composer check-code
+```bash
+cd php-telegram-bot
+composer install
+composer check-code

 Which should give you no output, indicating that there are no coding standard errors.
 And then (remember to set up your test database!):
 
-    composer test
+```bash
+composer test
+```
 
 Which should give you no failures or errors. You can ignore any skipped tests as these are for external tools.
