 ### Platform Support
 
-`somesy` is now compatible with MacOS, Ubuntu, and Windows. For Windows users, it's important to use a version `0.3.0` or higher of somesy to ensure compatibility.
+Starting with version **0.3.0**, `somesy` supports Linux, MacOS and Windows.

+While `somesy` is modifying existing files for most supported formats and implements
+features such as person identification and merging,
 [CodeMeta](https://codemeta.github.io/) is implemented differently.
 
-
-Other formats implement person identification and merging, but for codemeta.json, there's a notable exception: person data gets overwritten by the source file. Given that `codemeta.json` is a `JSON-LD file`, it inherently represents data as a graph, allowing for diverse information storage methods. To navigate this complexity and ensure accurate data representation, we opt to regenerate the `codemeta.json` file directly from the source file.
+As that `codemeta.json` is a [**JSON-LD**](https://json-ld.org/) file, it actually represents a graph,
+has various equally valid representations in a JSON file.
+Thus, supporting the same features as for other formats is technically much more
+challenging, if at all feasible. Therefore, for the time being, we regenerate the
+`codemeta.json` file directly from the source file, in order to avoid data inconsistency
+due to many pitfalls hiding in the details of the format.

 As `codemeta.json` is considered a technical "backend-format" derived from other

 ## Using somesy to insert metadata into project documentation
 
 While `somesy` can synchronize structured metadata files and formats, there is a common case that cannot be covered by the `sync` command - when project metadata should appear in plain text documents, such as documentation files and web pages.
