 Bow OpenAPI is a command line tool to generate a network client written in Swift from an OpenAPI specification that uses the environmental effect type `EnvIO` from [Bow](https://bow-swift.io/). Its main features are:
 
+💡 [Automatic generation](https://openapi.bow-swift.io/docs/generation-examples/basic-generation/) of network clients written in Swift from an OpenAPI / Swagger specification file, in YAML or JSON formats.
+
+📦 Provision of a [Swift Package](https://openapi.bow-swift.io/docs/consuming-generated-code/adding-the-module-to-your-project/) that can be consumed from Swift Package Manager.
+
+🔨 [Integration with Xcode](https://openapi.bow-swift.io/docs/quick-start/integration-in-xcode/) as a build phase to always keep your code in sync with your specification.
+
+💥 Usage of [Environmental Effects](https://openapi.bow-swift.io/docs/consuming-generated-code/running-a-network-request/) from [Bow](https://bow-swift.io) to suspend side-effects, and improve their composition and testability.
+
+✅ [Enhanced test support](https://openapi.bow-swift.io/docs/consuming-generated-code/testing-your-network-calls/) for integration or end-to-end test with no mocks.
+
 ## Parsing of OpenAPI specifications
 
 Bow OpenAPI is able to consume OpenAPI / Swagger specifications as either JSON or YAML files. It relies on the `swagger-codegen` command line tool to parse these files, and then provides a set of templates to customize the output of the tool, together with an additional processing of the result.

+**Bow OpenAPI** is a command-line tool to generate a Swift network client from an OpenAPI / Swagger specification file. Please, refer to the [project website](https://openapi.bow-swift.io) for extensive and detailed documentation about the project.
+
+### Features
+
+💡 [Automatic generation](https://openapi.bow-swift.io/docs/generation-examples/basic-generation/) of network clients written in Swift from an OpenAPI / Swagger specification file, in YAML or JSON formats.
+
+📦 Provision of a [Swift Package](https://openapi.bow-swift.io/docs/consuming-generated-code/adding-the-module-to-your-project/) that can be consumed from Swift Package Manager.
+
+🔨 [Integration with Xcode](https://openapi.bow-swift.io/docs/quick-start/integration-in-xcode/) as a build phase to always keep your code in sync with your specification.
+
+💥 Usage of [Environmental Effects](https://openapi.bow-swift.io/docs/consuming-generated-code/running-a-network-request/) from [Bow](https://bow-swift.io) to suspend side-effects, and improve their composition and testability.

+
+## 💻 Installation
+
+You can [install Bow OpenAPI](https://openapi.bow-swift.io/docs/quick-start/installation-guide/) using [Homebrew](https://brew.sh/index_es). Its formula is not still in the main repository; therefore, you need to tap it first, before installing it:
+
+```bash
+brew tap bow-swift/bow
+brew install bow-openapi
+```
+
+## ⚙️ Usage
+
+You can [invoke the tool](https://openapi.bow-swift.io/docs/quick-start/how-to-run-bow-openapi/) with the following parameters:
+
+```bash
+bow-openapi --name <NAME> --schema <YAML | JSON> --output <FOLDER>
+```
+
+- `name` is the name for the generated module in the resulting Swift Package. You will have to import it in your code using `import <NAME>`.
+- `schema` is the path to the OpenAPI / Swagger specification file. It accepts both YAML or JSON formats.
+- `output` is the folder where the result will be saved.
