 One of the main reasons for this is the abstraction and poor execution of many automation tools. They come with their own configuration (`YAML`_ syntax) specification or limit the user to one specific programming language. Testing is nearly impossible because most automation tools lack the ability to mock services and subsystems. Even tiny things, for example parsing a JSON file, are sometimes really painful because external, outdated libraries were used and not included in the standard framework.
 
-We believe it's time to remove all these abstractions and come back to our roots. Are you tired of writing endless lines of YAML-code? Are you sick of spending days forced to write in a language that does not suit you and is not fun at all? Do you enjoy programming in a language you like? Then Gaia is for you.

 =================
 
 .. begin-architecture
 
-Gaia is based on `HashiCorp's go-plugin`_. It's a `plugin system`_ that uses `gRPC`_ to communicate over `HTTP/2`_. HashiCorp developed this tool initially for `Packer`_ but it's now heavily used by `Terraform`_, `Nomad`_, and `Vault`_ too.

-Plugins, which we named `pipelines <What is a pipeline?_>`_, are applications which can be written in any programming language as long as `gRPC`_ is supported. All functions, which we call `jobs <What is a job?>`_, are exposed to Gaia and can form up a dependency graph which describes the order of execution.

 Pipelines can be compiled locally or simply over the build system. Gaia clones the git repository and automatically builds the included pipeline. If a change (`git push`_) happened, Gaia will automatically rebuild the pipeline for you*.
 
-After a pipeline has been started, all log output are returned back to Gaia and displayed in a detailed overview with their final result status.

 Gaia uses `boltDB` for storage. This makes the installation step super easy. No external database is currently required.

-Gaia is currently in alpha version available. We extremely recommend to not use it for mission critical jobs and for production usage yet. Things will change in the future and essential features may break.
+Gaia is currently available as alpha version. We extremely recommend to not use it for mission critical jobs and for production yet. Things will change in the future and essential features may break.
 
 One of the main issues currently is the lack of unit- and integration tests. This is on our to-do list and we are working on this topic with high priority.
 
-It is planned that other programming languages should be supported in the next few month. It is up to the community which languages will be supported next.

 If you think you found a good first issue, please consider this list as a short guide:
 
-* If the issue is clear and you have no questions, please leave a short comment that you start working on this. The issue will be usually blocked for two weeks to solve it.
-* If something is not clear or you are unsure what to do, please leave a comment so we can add further discription.
-* Make sure that your development environment is configured and setup. You need `Go installed`_ on your machine and also `nodeJS`_ for the frontend. Clone this repository and run the **make** command inside the cloned folder. This will start the backend. To start the frontend you have to open a new terminal window and go into the frontend folder. There you run **npm install** and then **npm run dev**. This should automatically open a new browser window.
