1. Open the deposit interface
Log in on SONAR. On your account, you have a link to the administration. From there, you can use the "Deposits" menu in the header. You must be attached to an organisation with a "submitter" or "moderator" role in order to be able to deposit documents.
2. Upload your file(s), and then follow the steps to complete the process
For text documents, use preferably the PDF format.
Note that you can fill in the metadata form (steps 2 and 3 of the deposit) by automatically extracting data from the deposited PDF file. For that, use the button "Import metadata" in step 2, then "Analyze uploaded PDF". This process retrieves fields like title, abstract, authors and corresponding affiliations, etc. but it does not guarantee 100% accuracy in all cases, it strongly depends on how contents are coded within the PDF. The extracted data can then be manually completed or corrected.
Other metadata import methods are being prepared.
3. Click on "Submit"
If you are a submitter, your submission will be validated by a moderator, to ensure that data is entered completely and correctly. If you are a validator, the document can be directly made visible.

The "Sherpa Romeo" site lists in detail the conditions of a large number of publishers. The local head of your organisation and the moderators should also be able to provide assistance in this matter.
