+## Learn more about this file at 'https://www.gitpod.io/docs/references/gitpod-yml'
+##
+## This '.gitpod.yml' file when placed at the root of a project instructs
+## Gitpod how to prepare & build the project, start development environments
+## and configure continuous prebuilds. Prebuilds when enabled builds a project
+## like a CI server so you can start coding right away - no more waiting for
+## dependencies to download and builds to finish when reviewing pull-requests
+## or hacking on something new.
+##
+## With Gitpod you can develop software from any device (even iPads) via 
+## desktop or browser based versions of VS Code or any JetBrains IDE and
+## customise it to your individual needs - from themes to extensions, you
+## have full control.
+##
+## The easiest way to try out Gitpod is install the browser extension:
+## 'https://www.gitpod.io/docs/browser-extension' or by prefixing
+## 'https://gitpod.io#' to the source control URL of any project.
+##
+## For example: 'https://gitpod.io#https://github.com/gitpod-io/gitpod'
+
+
+## The 'image' section defines which Docker image Gitpod should use. 
+## By default, Gitpod uses a standard Docker Image called 'workspace-full'
+## which can be found at 'https://github.com/gitpod-io/workspace-images'
+##
+## Workspaces started based on this default image come pre-installed with
+## Docker, Go, Java, Node.js, C/C++, Python, Ruby, Rust, PHP as well as
+## tools such as Homebrew, Tailscale, Nginx and several more.
+##
+## If this image does not include the tools needed for your project then
+## a public Docker image or your own Docker file can be configured.
+## 
+## Learn more about images at 'https://www.gitpod.io/docs/config-docker'
+
+#image: node:buster                        # use 'https://hub.docker.com/_/node'
+#
+#image:                                    # leave image undefined if using a Dockerfile
+#  file: .gitpod.Dockerfile                # relative path to the Dockerfile from the
+#                                          # root of the project
+
+## The 'tasks' section defines how Gitpod prepares and builds this project
+## or how Gitpod can start development servers. With Gitpod, there are three
+## types of tasks:
+##
+## - before: Use this for tasks that need to run before init and before command. 
+## - init: Use this to configure prebuilds of heavy-lifting tasks such as
+##         downloading dependencies or compiling source code.
+## - command: Use this to start your database or application when the workspace starts.
+##
+## Learn more about these tasks at 'https://www.gitpod.io/docs/config-start-tasks'
+
+#tasks:
+#  - before: |
+#      # commands to execute...
+#

-/bin/configs/python*` to update the Python-related samples under [`samples`](https://github.com/openapitools/openapi-generator/tree/master/samples).

- Run the tests in the sample folder using maven `mvn integration-test -f /path/to/pom.xml`, e.g. `mvn integration-test -f samples/client/petstore/python/pom.xml`.

 OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs,  documentation and configuration automatically given an [OpenAPI Spec](https://github.com/OAI/OpenAPI-Specification) (both 2.0 and 3.0 are supported).

-* [Java 8](https://www.oracle.com/technetwork/java/index.html)
+* [Java 11](https://adoptium.net/)

-* [Apache Maven 3.3.4 or greater](https://maven.apache.org/)

+After cloning the project, you can build it from source using [maven wrapper](https://github.com/takari/maven-wrapper):
+
+- Linux: `./mvnw clean install`
+- Windows: `mvnw.cmd clean install`
+
+#### Nix users
+
+If you're a nix user, you can enter OpenAPI Generator shell, by typing:
 ```sh
-mvn clean install
+nix develop
 ```
+It will enter a shell with Java 11 installed.

-If you don't have maven installed, you may directly use the included [maven wrapper](https://github.com/takari/maven-wrapper), and build with the command:
+Direnv supports automatically loading of the nix developer shell, so if you're using direnv too, type:
 ```sh
-./mvnw clean install
+direnv allow
 ```
+and have `java` and `mvn` set up with correct versions each time you enter project directory.

 The default build contains minimal static analysis (via CheckStyle). To run your build with PMD and Spotbugs, use the `static-analysis` profile:

-```sh
-mvn -Pstatic-analysis clean install
-```
+- Linux: `./mvnw -Pstatic-analysis clean install`
+- Windows: `mvnw.cmd -Pstatic-analysis clean install`

 ## [6 - About Us](#table-of-contents)

+What's the design philosophy or principle behind OpenAPI Generator?
+
+We focus on developer experience. The generators should produce code, config, documentation, and more that are easily understandable and consumable by users. We focused on simple use cases to start with (bottom-up approach). Since then the project and the community have grown a lot: 300k weekly downloads via NPM CLI wrapper, 20M downloads via openapi-generator-cli docker image just to highlight a few. We've gradually supported more features (e.g. oneOf, anyOf introduced in OpenAPI 3.0) in various generators and we will continue this approach to deliver something based on our understanding of user demand and what they want, and continue to add support of new features introduced in OpenAPI specification (such as v3.1 and future versions of the OpenAPI specification).
