 Helix is the distributed test platform that we use to run tests.  We build a helix payload that contains the publish directory of every test project that we want to test

 This will restore, and then publish all the test project including some bootstrapping scripts that will install the correct dotnet runtime/sdk before running the test assembly on the helix machine(s), and upload the job to helix.

 ## Differences from running tests locally
+
 Most tests that don't just work on helix automatically are ones that depend on the source code being accessible. The helix payloads only contain whatever is in the publish directories, so any thing else that test depends on will need to be included to the payload.
 
 This can be accomplished by using the `HelixContent` property like so.

 ## How to skip tests on helix
+
 There are two main ways to opt out of helix
+
 - Skipping the entire test project via `<BuildHelixPayload>false</BuildHelixPayload>` in csproj (the default value for this is IsTestProject).
-- Skipping an individual test via `[SkipOnHelix("url to github issue")]` which might require including a compile reference to: `<Compile Include="$(SharedSourceRoot)test\SkipOnHelixAttribute.cs" />`
+- Skipping an individual test via `[SkipOnHelix("url to github issue")]`.
 
 Make sure to file an issue for any skipped tests and include that in a comment next to either of these
