     title: Documentation that simply works
@@ -22,6 +20,34 @@ We present a database repository system that allows researchers to ingest data i
 through common interfaces, provides efficient access to arbitrary subsets of data even when the underlying data store is
 evolving, allows reproducing of query results and supports findable-, accessible-, interoperable- and reusable data.
 
+## Features
+
+### Built-in search
+
+DBRepo makes your dataset searchable without extra effort: most metadata is generated automatically for data in your 
+databases. The fast and powerful OpenSearch database allows a fast retrieval of any information. Adding semantic mapping
+through a suggestion-feature, allows machines to properly understand the context of your data. [Learn more.](../system-services-search/)
+
+### Citable datasets
+
+Adopting the recommendations of the RDA-WGDC, arbitrary subsets can be precisely, persistently identified using
+system-versioned tables of MariaDB and the DataCite schema for minting DOIs. External systems i.e. metadata harvesters
+(OpenAIRE, Google Datasets) can access these datasets through OAI-PMH, JSON-LD and FAIR Signposting protocols.
+[Learn more.](../system-services-metadata/)
+
+### Powerful API for Data Scientists
+
+With our strongly typed Python Library, Data Scientists can import, export and work with data from Jupyter Notebook or
+Python script, optionally using Pandas DataFrames. For example: the AMQP API Client can collect continuous data from
+edge devices like sensors and store them asynchronous in DBRepo. [Learn more.](../usage-python/)
+
+### Cloud Native
+
+Our lightweight Helm chart allows for installations on any cloud provider or private-cloud setting that has an
+underlying PV storage provider. DBRepo can be installed from the Artifacthub repository. Databases are managed as 
+MariaDB Galera Cluster with high degree of availability ensuring your data is always accessible.
+[Learn more.](../deployment-helm/)

-### Build

-Install the build dependencies under Debian 
-12 ([Instructions for Docker Engine](https://docs.docker.com/engine/install/debian/#install-using-the-repository)):
+Recommended for getting familiar with the system.
 
-```console
-$ apt install -y bash maven openjdk-17-jdk nodejs && npm install --global yarn
-$ node --version
-v18.19.0
-```
-
-Build the Docker containers:
-
-```console
-./bin/build-docker.sh
-```
-
-### Test
-
-Install the [build dependencies](#build) as they also cover the test dependencies.
-
-Test the backend and frontend:
-
-```console
-./bin/test.sh
-```
-
-## Run
+### Run
 
 After [building the docker containers](#build) you can run them using the default `docker-compose.yml` in the root of
 the sourcecode directory. This starts all services in the background (as daemons hence the `-d` flag).
 
-```console
-$ docker compose up -d
+```shell
+make start-dev
 ```
 
 Optionally view all logs in real-time:
 
-```console
-$ docker compose logs -f
+```shell
+docker compose logs -f
 ```
 
+## Kubernetes
+
+Recommended for operational deployment.
+
+See the [Helm Chart](https://artifacthub.io/packages/helm/dbrepo/dbrepo) on Artifact Hub.

+id;author;abstract
+1;George Orwell;The setting of 1984 is a dystopia: an imagined world that is far worse than our own, as opposed to a utopia, which is an ideal place or state. Other dystopian novels include Aldous Huxley's Brave New World, Ray Bradbury's Fahrenheit 451, and Orwell's own Animal Farm. When George Orwell wrote 1984, the year that gives the book its title was still almost 40 years in the future. Some of the things Orwell imagined that would come to pass were the telescreen, a TV that observes those who are watching it, and a world consisting of three megastates rather than hundreds of countries. In the novel, the country of Eastasia apparently consists of China and its satellite nations; Eurasia is the Soviet Union; and Oceania comprises the United States, the United Kingdom, and their allies. Another of Orwell's creations for 1984 is Newspeak, a form of English that the book's totalitarian government utilizes to discourage free thinking. Orwell believed that, without a word or words to express an idea, the idea itself was impossible to conceive and retain. Thus Newspeak has eliminated the word "bad," replacing it with the less-harsh "ungood." The author's point was that government can control us through the words.
+2;George Orwell;Animal Farm is an allegory, which is a story in which concrete and specific characters and situations stand for other characters and situations so as to make a point about them. The main action of Animal Farm stands for the Russian Revolution of 1917 and the early years of the Soviet Union. Animalism is really communism. Manor Farm is allegorical of Russia, and the farmer Mr. Jones is the Russian Czar. Old Major stands for either Karl Marx or Vladimir Lenin, and the pig named Snowball represents the intellectual revolutionary Leon Trotsky. Napoleon stands for Stalin, while the dogs are his secret police. The horse Boxer stands in for the proletariat, or working class. The setting of Animal Farm is a dystopia, which is an imagined world that is far worse than our own, as opposed to a utopia, which is an ideal place or state. Other dystopian novels include Aldous Huxley's Brave New World, Ray Bradbury's Fahrenheit 451, and Orwell's own 1984. The most famous line from the book is "All animals are equal, but some are more equal than others." This line is emblematic of the changes that George Orwell believed followed the 1917 Communist Revolution in Russia. Rather than eliminating the capitalist class system it was intended to overthrow, the revolution merely replaced it with another hierarchy. The line is also typical of Orwell's belief that those in power usually manipulate language to their own benefit.

+    XML Schema which can be used to validate replies to all OAI-PMH 
+    v2.0 requests. Herbert Van de Sompel, 2002-05-13.
+    Validated with XML Spy v.4.3 on 2002-05-13.
+    Validated with XSV 1.203.2.45/1.106.2.22 on 2002-05-13.
+    Added definition of protocolVersionType instead of using anonymous 
+    type. No change of function. Simeon Warner, 2004-03-29.
+    Tightened definition of UTCdatetimeType to enforce the restriction 
+    to UTC Z notation. Simeon Warner, 2004-09-14.
+    Corrected pattern matches for setSpecType and metadataPrefixType
+    to agree with protocol specification. Simeon Warner, 2004-10-12.
+    Spelling correction. Simeon Warner, 2008-12-07.
