 To initiate a submission of data to GHGA, please contact us via the [contact form](https://www.ghga.de/about-us/contact) by using the topic *“Data Submission”*. A GHGA Data Steward will be assigned and guide you through the process, which consists of the following steps:
 
 1. Signing of a Data Processing Contract, see [here](dpc_preparation.md).
-1. Preparation of the non-personal metadata
-1. Research Data File submission
+2. Preparation of the non-personal metadata
+3. Research Data File submission
 
 The signing of a DPC has to be finalized before a Data Steward is allowed to interact with the non-personal metadata. Preparation of the metadata and file submission can be done on the submitter side in parallel.
 
 ## 2. Metadata preparation
-The GHGA metadata model aims at facilitating comprehensive submissions that maximize the amount of collected metadata in a FAIR manner. To provide a streamlined submission of metadata, the model is designed to closely resemble a bottom-up-omics experiment:
-
-  ![OmicsWF](../../assets/img/OmicsWF.png){ width="500" }
-
-Submissions can be either prepared in JSON format or by using a [submission spreadsheet](https://github.com/ghga-de/ghga-metadata-schema/tree/main/spreadsheets). An example submission can be found in our [Github repository containing example data](https://github.com/ghga-de/example-data). The provided metadata are categorized as **Research Metadata** and **Administrative Metadata**, whereas the former collect information about the experimental and data acquisition process and the latter about data access, rights management and disposition. It is crucial, that only non-personal metadata are submitted to GHGA.

 ### Research Metadata
+To provide a streamlined submission of metadata, the model is designed to closely resemble a bottom-up-omics experiment:

+  ![OmicsWF](../../assets/img/OmicsWF.png){ width="800" }
 
 Similar to an experimental procedure, [**Individuals**](https://docs.ghga.de/metadata/entities/#individual) that are subject to investigation should be defined first. 
 In order to describe an individual, data submitters are required to provide information about sex and are recommended to provide information about phenotypic features and diagnoses.
