-# Requirements
+# KorAP-Docker
+
+KorAP consists of several components,
+but they can easily be installed together using
+[Docker](https://www.docker.com/).
+This repository contains a recipe to install all
+components needed to run KorAP on a local machine
+with a single command.
+
+In addition, all relevant tools are installed and
+made available that are necessary for data conversion
+and indexing of corpora in the widely used TEI-P5/i5
+format for KorAP.
+For different options of the tools we refer to the
+respective repositories.
+
+## Requirements
 
 Install [docker](https://www.docker.com/) and [docker compose](https://github.com/docker/compose).
 
-# Starting
+## Starting
 
 To download, intialize and run KorAP pointing to a certain directory index
-(in this example `myindex` in the local directory), run
+(in this example `index` in the local directory), run
 
 ```shell
-$ INDEX=./myindex docker-compose up
+$ INDEX=./index docker-compose up
 ```
 
 This will make the frontend be available at
 `localhost:64543`.

+## Corpus Conversion
 
 Depending on the corpus data to be indexed, it must first be converted.
 In the case of a conversion from TEI p5/i5 format, the tools

 into individual Krill JSON, the following command ...
 
 ```shell
+$ mkdir json
 $ docker run --rm -u root \
   -v ${PWD}/:/kalamar/data/ korap/kalamar korapxml2krill archive \
-  -z -i /kalamar/data/mycorpus.zip -o ./data/

 ```
 
 ... will use [korapxml2krill](https://github.com/KorAP/KorAP-XML-Krill).
 
 Depending on how the source data is designed, different parameters must be specified for the conversion.

+
+## Index Creation
+
+[Krill](https://github.com/KorAP/Krill)'s indexer tool can now
+be used to index the json files:
+
+```shell
+$ mkdir index
+$ docker run -u root --rm -v ${PWD}/:/data/ korap/kustvakt \
+  Krill-Indexer.jar -c kustvakt-lite.conf \
+  -i /data/json -o /data/index/
+```
