Improve the documentation by moving the README.md "Usage example" section to a standalone GETTING_STARTED.md file

[fabiobrz]

In order to improve the project documentation, the main README.md file should be as simple as possible, and provide links to standalone *.md files which document specific topics.

This issue is tracking the work for updating the README.md file so that:

• the Usage example section is migrated to a new, standalone GETTING_STARTED.md file
• The contents of the new GETTING_STARTED.md file are improved in terms of wording and readability
• a link to GETTING_STARTED.md is added to the main README.md file for reading about how to get started with Intersmash easily.

---

• Environment: project repository documentation
• Steps to reproduce: N/A

@dosu could you please create a PR that implements the changes required by this issue?

Hey @fabiobrz! 👋 I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. Let's squash those bugs together!

# Create a new branch for the changes
git checkout -b move-usage-example-to-getting-started

# Create the new GETTING_STARTED.md file and move the "Usage example" section to it
cat <<EOL > GETTING_STARTED.md
# Getting Started

## Usage Example

The following outlines a simple test scenario in which PostgresSql and Wildfly are used.

```java
@Intersmash({ // 1
        @Service(PostgresqlApp.class),
        @Service(WildflyOpenShiftApp.class)
    }
)
public class SampleTest {
    @ServiceUrl(WildflyOpenShiftApp.class) // 2
    private String wildflyRouteUrl;

    @ServiceProvisioner(WildflyOpenShiftApp.class) // 3
    private OpenShiftProvisioner wildflyOpenShiftProvisioner;

    @ServiceProvisioner(PostgresqlApp.class) 
    private OpenShiftProvisioner postgresqlProvisioner;

    @Test
    public void test() {
        // Do your thing.
    }
}

1. By decorating the class with the Intersmash annotation, the user registers their interface implementation classes of the services to be used in this test.
2. Injects into the field a string containing the URL to communicate with Wildfly.
3. Injects into the field the provisioner for Wildfly and PostgreSQL. These classes enable the test code to, scale the deployment up and down, for example.

An example implementation of PostgreSQLTemplateOpenShiftApplication, which leverages templates to describe a PostgreSql service, would look like this. For this service the user needs to identify the template to use; POSTGRESQL_EPHEMERAL in this case and provides the name of the service.

import org.jboss.intersmash.application.openshift.PostgreSQLTemplateOpenShiftApplication;
import org.jboss.intersmash.application.openshift.template.PostgreSQLTemplate;

public class PostgresqlApp implements PostgreSQLTemplateOpenShiftApplication {
    static String NAME = "postgresql";

    @Override
    public PostgreSQLTemplate getTemplate() {
        return PostgreSQLTemplate.POSTGRESQL_EPHEMERAL;
    }

    @Override
    public String getName() {
        return NAME;
    }
}

An example implementation of WildflyImageOpenShiftApplication, which leverages s2i build to deploy a WildFly application service, would look like this. The application's name is declared and the build of the Wildfly image to deploy is retrieved and provided to the framework.

import org.jboss.intersmash.application.openshift.WildflyImageOpenShiftApplication;

public class WildflyOpenShiftApp implements WildflyImageOpenShiftApplication {
  @Override
  public String getName() {
    return "wildfly-app";
  }

  @Override
  public BuildInput getBuildInput() {
    return new BuildInputBuilder().archive(app).build();
  }
}

EOL

Remove the "Usage example" section from README.md

sed -i '/## Usage Example/,$d' README.md

Add a reference to the new GETTING_STARTED.md file in README.md

echo -e "\nFor usage examples, see Getting Started." >> README.md

Stage the changes

git add README.md GETTING_STARTED.md

Commit the changes

git commit -m "Move 'Usage example' section from README.md to standalone GETTING_STARTED.md file"

Push the changes to the remote repository

git push origin move-usage-example-to-getting-started

Create a pull request

gh pr create --title "Move 'Usage example' section to GETTING_STARTED.md" --body "This PR moves the 'Usage example' section from README.md to a standalone GETTING_STARTED.md file to improve documentation structure."

Thanks @dosu! I have some comments regarding the changes that you suggested:

1. The text which should be injected into the new GETTING_STARTED.md file via the cat command is broken, maybe due to the backtick characters?
2. The sed -i '/## Usage Example/,$d' README.md command would remove all the content after the "Usage example" title, not just the related section.
3. When creating a PR that resolves an Intersmash issue, the feature branch name should be prefixed by the issue identifier, i.e. issues-201 in this very case. Similarly, the PR commit message should be prefixed by the same identifier contained by square brackets, and followed by the commit message.

So, you did quite a good job this time, although as far as this type of request is concerned, there's room for you to improve by taking the above comments into account. Thanks for your help.

Here are the updated steps to address the comments:

1. Fix the text injection into GETTING_STARTED.md: Use a different method to avoid issues with backtick characters.
2. Correct the sed command: Ensure only the "Usage example" section is removed.
3. Use the correct branch name and commit message format: Prefix with the issue identifier.

# Create a new branch for the changes
git checkout -b issues-201-move-usage-example-to-getting-started

# Create the new GETTING_STARTED.md file and move the "Usage example" section to it
cat << 'EOL' > GETTING_STARTED.md
# Getting Started
