-Known Issues
-------------
+# Known Issues
 
 - On .NET Core and .NET 5, zip packages do not have a way to stream data. Thus, the working set can explode in certain situations. This is a [known issue](https://github.com/dotnet/runtime/issues/1544).
 - On .NET Core, targeting .NET Framework 4.5+, and .NET 5, `System.Uri` will not parse invalid links. This causes an exception. A workaround in v2.12.0+ of OpenXml SDK is to use `OpenSettings.RelationshipErrorRewriter` to rewrite them to something that can be parsed. A discussion is available [here](https://github.com/dotnet/runtime/issues/26084) to enable something more robust in `System.IO.Packaging`.
 - On .NET Framework, an `IsolatedStorageException` may be thrown under certain circumstances. This generally occurs when manipulating a large document in an environment with an AppDomain that does not have enough evidence. A sample with a workaround is available [here](/samples/IsolatedStorageExceptionWorkaround).
 
-Documentation
--------------
+# Documentation
 
 The functionality of the specific classes in this version of the Open XML SDK is similar to version 2.5, therefore the [Open XML SDK 2.5 for Office](http://msdn.microsoft.com/en-us/library/office/bb448854.aspx) documentation available on MSDN is still accurate.
 
 In addition to open sourcing of the SDK, Microsoft has opened up the conceptual documentation for public review / contributions.  A copy of the documentation is  available for you to edit and review [in GitHub](https://github.com/OfficeDev/office-content).
