 ## redborder-serverspec-manager
+
 Infrastructure integration testing for a redborder manager machine. The idea is to run the tests in a machine that is the validator local machine, so the target machine is affected by the tests.
 
 ## Installation
+
 First, clone this repository on your workstation. Then install the gemes by executing this:
-```ssh
+
+```cmd
 bundle install
 ```
+
 Sometimes you need to make sure that you share your public ssh key to target machine:
-```
+
+```cmd
 ssh-copy-id root@<target_ip>
 ```
 
 ## Running Tests
+
 To run all tests, use the following command:
-```
+
+```cmd
 rake spec
 ```
 
 Optional parameters:
-* TARGET_HOST: Machine where the tests will run via SSH.
-* LOGIN_USERNAME: Username for SSH connection to the test machine.
-* LOGIN_PASSWORD: Password for SSH connection to the test machine.
-* IS_CLUSTER: Boolean to indicate if the target machine is a cluster.
-* -j 10 -m: To run tests in pararell
-Example with optional parameters:
-```
-TARGET_HOST="10.1.209.50" LOGIN_USERNAME="root" LOGIN_PASSWORD="redborder" rake spec
+
+- **TARGET_HOST**: Machine where the tests will run via SSH.
+- **LOGIN_USERNAME**: Username for SSH connection to the test machine.
+- **LOGIN_PASSWORD**: Password for SSH connection to the test machine.
+- **IS_CLUSTER**: Boolean to indicate if the target machine is a cluster.
+- **-j 10 -m**: To run tests in pararell
+  Example with optional parameters:
+
+```cmd
+IS_CLUSTER="false" TARGET_HOST="10.1.209.50" LOGIN_USERNAME="root" LOGIN_PASSWORD="redborder" rake spec
 ```
 
 To run a specific test type, use the following command:
-```
+
+```cmd
 rake spec:configuration
 ```
 
 To run a specific test in a spec file, better use tags:
-```
+
+```cmd
 rspec --tag tag_name
-To run a specific script test, use the following command:
 ```
-rspec spec/services/cgroup_spec.rb 
+
+To run a specific script test, use the following command:
+
+```cmd
+rspec spec/services/cgroup_spec.rb
 ```
 
 List of Available Rake Tasks:
-To view the list of available Rake tasks, use the following command:
-```
+
+```cmd
 rake -T
 ```
 
 ## Developing tests
 
-On creating a new test, is important to follow the Rakefile structure as the directory structure.
+When creating a new test, it is important to follow the directory structure outlined in the Rakefile. This structure helps maintain organization and clarity within the test suite.
 
 Directory structure:
-```
-└── spec/
-    ├── spec_helper.rb
-    │
-    ├── services/
-    │   ├── ... > PUT YOUR TESTS HERE
-    │
-    ├── configuration/
-    │   ├── ... > OR HERE
-    │
-    ├── modules/
-    │   ├── monitor
-    |       ├── ... > OR HERE
-    │
-    └── helpers/
-        ├── ...         
-```
 
-Tag a describe to run by specific command ie:
-```
-describe ("Any test for this"), :tagname do
-```
+```conf
+spec/
+├── spec_helper.rb
+├── services/
+│   ├── ...  # Place your service-related tests here
+├── configuration/
+│   ├── ...  # Place your configuration-related tests here
+├── modules/
+│   ├── monitor/
+│   ├── ...  # Place your module-related tests here
+└── helpers/
+    ├── ...  # Place your helper-related tests here
