+## Using Metafacture as a Java library
+
+If you want to use Metafacture in your own Java projects all you need is to add some dependencies to your project. As of Metafacture 5, the single metafacture-core package has been replaced with a number of domain-specific packages. You can find the list of packages on [Maven Central](https://search.maven.org/search?q=g:org.metafacture).
+
+Alternatively, you can simply guess the package names from the top-level folders in the source code repository -- they are the same. 
+
+For instance, if you want to use the `metafacture-io` library in your project, simply add the following dependency to your `pom.xml`:
+
+```xml
+<dependency>
+    <groupId>org.metafacture</groupId>
+    <artifactId>metafacture-io</artifactId>
+    <version>$VERSION</version>
+</dependency>
+```
+
+or if Gradle is your build tool of choice use:
+
+```groovy
+dependencies {
+    implementation 'org.metafacture:metafacture-io:$VERSION'
+}
+```
+
+To use Fix you would declare `metafix` instead of `metafacture-io` as in the example above. Note that `metafix` is not published to maven central but only to [github releases](https://github.com/metafacture/metafacture-fix/releases).
+
+Occasionally, we publish snapshot builds on [Sonatype OSS Repository](https://oss.sonatype.org/index.html#nexus-search;gav~org.metafacture~~~~~kw,versionexpand). The version number is derived from the branch name. Snapshot builds from the master branch always have the version `master-SNAPSHOT`. We also provide sometimes pre releases as github packages.

-For a complete introduction to Metafacture in German, check out the latest iteration of [our Metafacture Workshop](https://slides.lobid.org/2022-12-metafacture-workshop/#/). For different use cases, e.g. using Metafacture as a library, using the Morph language, and more, see [our documentation collection](https://github.com/metafacture/metafacture-documentation).
+Get familar with [FLUX](https://github.com/metafacture/metafacture-documentation/blob/master/Flux-User-Guide.md) and [FIX](https://github.com/metafacture/metafacture-documentation/blob/master/Fix-User-Guide.md). And try out some Metafacture workflows.
+
+If you plan to use Metafacture as a Java library or if you wish to add commands to Flux you should get familar with the [Framework](https://github.com/metafacture/metafacture-documentation/blob/master/Framework-User-Guide.md).
