+## Making changes
+
+### Tests
+
+Whenever possible, changes should be accompanied by non-trivial tests that meaningfully exercise the core functionality of the new code being introduced.
+
+All tests are in the `Test/` directory at the repo root. Fast unit tests are in the `Test/L0` directory and by convention have the suffix `L0.cs`. For example: unit tests for a hypothetical `src/Runner.Worker/Foo.cs` would go in `src/Test/L0/Worker/FooL0.cs`.
+
+Run tests using this command:
+
+```sh
+cd src && ./dev.sh test
+```
+
+### Formatting
+
+After editing .cs files, always format the code using this command:
+
+```sh
+cd src && ./dev.sh format
+```
+
+### Feature Flags
+
+Wherever possible, all changes should be safeguarded by a feature flag; `Features` are declared in [Constants.cs](src/Runner.Common/Constants.cs).

@@ -250,6 +250,42 @@ Two problem matchers can be used:
 }
 ```
 
+#### Default from path
+
+The problem matcher can specify a `fromPath` property at the top level, which applies when a specific pattern doesn't provide a value for `fromPath`. This is useful for tools that don't include project file information in their output.
+
+For example, given the following compiler output that doesn't include project file information:
+
+```
+ClassLibrary.cs(16,24): warning CS0612: 'ClassLibrary.Helpers.MyHelper.Name' is obsolete
+```
+
+A problem matcher with a default from path can be used:
+
+```json
+{
+    "problemMatcher": [
+        {
+            "owner": "csc-minimal",
+            "fromPath": "ClassLibrary/ClassLibrary.csproj",
+            "pattern": [
+                {
+                    "regexp": "^(.+)\\((\\d+),(\\d+)\\): (error|warning) (.+): (.*)$",
+                    "file": 1,
+                    "line": 2,
+                    "column": 3,

+                    "code": 5,
+                    "message": 6
+                }
+            ]
+        }
+    ]
+}
+```
+
+This ensures that the file is rooted to the correct path when there's not enough information in the error messages to extract a `fromPath`.

 #### Mitigate regular expression denial of service (ReDos)
 
 If a matcher exceeds a 1 second timeout when processing a line, retry up to two three times total.

 > IMPORTANT: Building your own runner is critical for the dev inner loop process when contributing changes.  However, only runners built and distributed by GitHub (releases) are supported in production.  Be aware that workflows and orchestrations run service side with the runner being a remote process to run steps.  For that reason, the service can pull the runner forward so customizations can be lost.
