 1. Install Codeception if it's not yet installed:
 
-```
-composer global require "codeception/codeception=2.0.*"
-composer global require "codeception/specify=*"
-composer global require "codeception/verify=*"
-```
+   ```
+   composer global require "codeception/codeception=2.0.*"
+   composer global require "codeception/specify=*"
+   composer global require "codeception/verify=*"
+   ```
 
-If you've never used Composer for global packages run `composer global status`. It should output:

-Changed current directory to <directory>

+   ```
+   Changed current directory to <directory>

-Then add `<directory>/vendor/bin` to you `PATH` environment variable. Now we're able to use `codecept` from command
-line globally.

 2. Install faker extension by running the following from template root directory where `composer.json` is:
 
-```
-composer require --dev yiisoft/yii2-faker:*
-```
+   ```
+   composer require --dev yiisoft/yii2-faker:*
+   ```
 
 3. Create `yii2_basic_tests` database and update it by applying migrations:
 
-```
-codeception/bin/yii migrate
-```
+   ```
+   codeception/bin/yii migrate
+   ```
 
 4. Build the test suites:
 
-```
-codecept build
-```
+   ```
+   codecept build
+   ```
 
 5. In order to be able to run acceptance tests you need to start a webserver. The simplest way is to use PHP built in
 webserver. In the `web` directory execute the following:
 
-```
-php -S localhost:8080
-```
+   ```
+   php -S localhost:8080
+   ```
 
 6. Now you can run the tests with the following commands:
 
-```
-# run all available tests
-codecept run
-# run acceptance tests
-codecept run acceptance
-# run functional tests
-codecept run functional
-# run unit tests
-codecept run unit
-```
+   ```
+   # run all available tests
+   codecept run
+   # run acceptance tests
+   codecept run acceptance
+   # run functional tests
+   codecept run functional
+   # run unit tests
+   codecept run unit
+   ```
