+# Spectral / JSON and YAML Linter
+
+JSON and YAML files can be linted with custom rules
+using [Spectral](https://github.com/stoplightio/spectral).
+The goal of using this linter is to ensure that best practice is followed.
+
+## Configuration
+
+Each repo will need one configuration file in the root of the repository.
+
+* `.spectral.yml` - Configures rules, which can be
+used to lint the JSON or YAML files.
+
+There are rules available to be used or customization is possible too.
+For more information, please visit [Spectral Document](https://meta.stoplight.io/docs/spectral/e5b9616d6d50c-rulesets)
+
+## Usage
+
+The linter can be used in different purpose,
+so a `FUNCTION` named `BUILD_SPECTRAL` is implemented
+to make it suit the purpose.
+
+`BUILD_SPECTRAL` contains four main arguments
+
+* `file_type`: the file type that will be lint.
+If it is set to `json`, minifying the JSON files will be performed.
+JSON and YAML linting are not allowed simultaneously to prevent conflicts.
+  Enforcing separate linting
+ensures accurate analysis for each file type in a folder, avoiding errors.
+* `dir`: A directory that contains files to be lint.
+* `src`: The root directory
+* `rule_set`: Rules set that is used
+
+## Example
+
+The example of using the linter can be found in [link](/Earthfile).
+The target `check-lint-openapi` is currently used for linting OpenAPI JSON file.
+The current rules set that is being used are:
+
+* [OWASP TOP 10](https://apistylebook.stoplight.io/docs/owasp-top-10)
+* [Spectral Documentation](https://github.com/stoplightio/spectral-documentation)
+* [OpenAPI](https://docs.stoplight.io/docs/spectral/4dec24461f3af-open-api-rules#openapi-rules)
+
+The example of OpenAPI documentation can be found in [link](/examples/openapi/example.json).
+<!-- markdownlint-disable max-one-sentence-per-line -->
+!!! Warning
+    Please note that this OpenAPI documentation provided
+    in this repository is used for example purposes only.
+<!-- markdownlint-enable max-one-sentence-per-line -->
+For more information about OpenAPI Specification, please visit the
+official [documentation](https://swagger.io/specification/#components-object).
