+##
+## 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 extenion:
+## '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'

+#                                         # prebuild completes thus Gitpod recommends moving

+#                                         # to a custom Dockerfile to make prebuilds faster
+#                                         # and to keep your codebase DRY.

+
+## The 'vscode' section defines a list of Visual Studio Code extensions from
+## the OpenVSX.org registry to be installed upon workspace startup. OpenVSX
+## is an open alternative to the proprietary Visual Studio Code Marketplace
+## and extensions can be added by sending a pull-request with the extension
+## identifier to https://github.com/open-vsx/publish-extensions
+##
+## The identifier of an extension is always ${publisher}.${name}.

+## For example: 'vscodevim.vim'

+## The 'github' section defines configuration of continuous prebuilds
