+You're website is now officially online. If you want to make updates on your website, you can do that either locally in your folder (like before) or directly in the GitHub repository. Either way, the important things to remember are:
+
+- Your local folder is now linked to a GitHub repository. The deployment is done over the GitHub repository. Every change you make in your local website folder needs to be **pushed to GitHub** in order to be updated on your website. Don't let yourself be confused by the changes you see when you look at your website locally via the localhost address. ==YOUR CHANGES ARE NOT ONLINE UNLESS THEY ARE DEPLOYED BY GITHUB!==
 
-Deploy your website with GitHub Pages.
+- If you make changes in GitHub and later decide to continue working locally, you need to do a **```git pull```** first to integrate the changes you made in GitHub into your local git repository. 
 
-The developers of Material for Mkdocs wrote a very good documentation about how to deploy your website on GitHub. Thus, I won't add anything to this but redirect you to the section [Publishing your site] on their website.

+This can happen sometimes. Try those things in the given order:

+- kill the current process in your terminal and start ```mkdocs serve``` again.
+- check your ```mkdocs.yml``` file for indentation errors. 
+- check your ```mkdocs.yml``` file for any other errors such as misspelling, invalid variable names, missing parameters etc.

+##### YAML-file

+- Make sure that you considered the indentation rules in your ```mkdocs.yml``` file.

+##### Images and PDFs
+
+**... my pdfs and images are not shown?**
+
+- Make sure you used the correct code for inserting an image. 
+- Is the path to your image correct?
+- Make sure that the folders where you store your pdfs and images are inside the ```docs``` folder. This is important because in your ```mkdocs.yml``` file you configured that the directory for your content (=```docs_dir```) is called ```docs```. So MkDocs expects ==everything you want to have on your website to be somewhere inside ```docs```.==
+
+**... my image shows in the local website but not after I deployed it with GitHub?**
+
+The deployment server is a bit more sensitive than the preview server.

+- Make sure you used the correct code for inserting an image. 
+- Is the path to your image correct?
+- Check the ==extension of your file==. If you changed the extension at some point, the image will not be recognized. E.g., if your image was originally a JPEG (.jpg) and you converted it to a PNG (.png) the image will not be recognized.
