 ### PEAR
 If you use PEAR, you can install PHP_CodeSniffer using the PEAR installer. This will make the `phpcs` and `phpcbf` commands immediately available for use. To install PHP_CodeSniffer using the PEAR installer, first ensure you have [installed PEAR](http://pear.php.net/manual/en/installation.getting.php) and then run the following command:
-
-    pear install PHP_CodeSniffer
-
+```bash
+pear install PHP_CodeSniffer
+```
 ### Git Clone
 You can also download the PHP_CodeSniffer source and run the `phpcs` and `phpcbf` commands directly from the Git clone:
-
-    git clone https://github.com/squizlabs/PHP_CodeSniffer.git
-    cd PHP_CodeSniffer
-    php bin/phpcs -h
-    php bin/phpcbf -h
-
+```bash
+git clone https://github.com/squizlabs/PHP_CodeSniffer.git
+cd PHP_CodeSniffer
+php bin/phpcs -h
+php bin/phpcbf -h
+```
 ## Getting Started
 
 The default coding standard used by PHP_CodeSniffer is the PEAR coding standard. To check a file against the PEAR coding standard, simply specify the file's location:
-
-    $ phpcs /path/to/code/myfile.php
-
+```bash
+phpcs /path/to/code/myfile.php
+```
 Or if you wish to check an entire directory you can specify the directory location instead of a file.
-
-    $ phpcs /path/to/code-directory
-
+```bash
+phpcs /path/to/code-directory
+```
 If you wish to check your code against the PSR-12 coding standard, use the `--standard` command line argument:
-
-    $ phpcs --standard=PSR12 /path/to/code-directory
+```bash
+phpcs --standard=PSR12 /path/to/code-directory
+```
 
 If PHP_CodeSniffer finds any coding standard errors, a report will be shown after running the command.
