+# License Scanning
+
+The VMR is regularly scanned for license references to ensure that only open-source license are used where relevant.
+
+License scanning pipline: https://dev.azure.com/dnceng/internal/_build?definitionId=1301 (internal only)
+
+License scanning test: https://github.com/dotnet/dotnet/blob/main/test/Microsoft.DotNet.SourceBuild.SmokeTests/LicenseScanTests.cs
+
+By default, running the pipeline will scan all repos within the VMR which takes several hours to run.
+The pipeline can be triggered manually to target a specific repo within the VMR by setting the `specificRepoName` parameter.
+This value should be the name of the repo within the VMR (i.e. a name of a directory within https://github.com/dotnet/dotnet/tree/main/src).
+To test source modifications intended to resolve a license issue, apply the change in an internal branch of the VMR.
+Run this pipeline, targeting your branch, and set the `specificRepoName` parameter to the name of the repo containing the change.
+
+The output of the pipeline is a set of test results and logs.
+The logs are published as an artifact and can be found at test/Microsoft.DotNet/SourceBuild.SmokeTests/bin/Release/netX.0/logs.
+It consists of the following:
+  * `UpdatedLicenses.<repo-name>.json`: This is the output of that gets compared to the stored baseline.
+    If they're the same, the test passes; if not, it fails. By comparing this file to the baseline, one can determine which new license
+    references have been introduced.
+    If everything is deemed to be acceptable, the developer can either update the allowed licenses, update the exclusions file, update the
+    baseline, or any combination.
+  * `scancode-results.json`: This is the raw output that comes from scancode. This file is useful for diagnostic purposes because it tells you
+    the exact line number of where a license has been detected in a file.

+/// <remarks>
+/// Each sub-repo of the VMR is scanned separately because of the amount of time it takes.
+/// When scanning is run, the test provides a list of files for the scanner to ignore. These include binary file types. It also includes
+/// .il/.ildump file types which are massive, causing the scanner to choke and don't include license references anyway.
+/// Once the scanner returns the results, a filtering process occurs. First, any detected license that is in the allowed list of licenses
+/// is filtered out. The test defines a list of such licenses that all represent open-source licenses. Next, a license exclusions file is
+/// applied to the filtering. This file contains a set of paths for which certain detected licenses are to be ignored. Such a path can be
+/// defined to ignore all detected licenses or specific ones. These exclusions are useful for ignoring false positives where the scanning
+/// tool has detected something in the file that makes it think it's a license reference when that's not actually the intent. Other cases
+/// that are excluded are when the license is meant as configuration or test data and not actually applying to the code. These exclusions
+/// further filter down the set of the detected licenses for each file. Everything that's left at this point is reported. It gets compared
+/// to a baseline file (which is defined for each sub-repo). If the filtered results differ from what's defined in the baseline, the test fails.
+/// 
+/// Rules for determining how to resolve a detected license:
+///   1. If it's an allowed open-source license, add it to the list of allowed licenses in LicenseScanTests.cs.
+///   2. If the file shouldn't be scanned as a general rule because of its file type (e.g. image file), add it to the list of excluded file types in LicenseScanTests.cs.
+///   3. Add it to LicenseExclusions.txt if the referenced license is one of the following:
+///     a. Not applicable (e.g. test data)
+///     b. False positive
+///   4. If the license is not allowed for open-souce, the license needs to be fixed. Everything else should go in the baseline file.
