+# Src-side test specifications
+
+The infra/testing folder in V8 contains test specifications, consumed and
+executed by the continuous infrastructure. Every master has an optional file
+named `<mastername>.pyl`. E.g. `tryserver.v8.pyl`.
+
+The structure of each file is:
+```
+{
+  <buildername>: [
+    {
+      'name': <test-spec name>,
+      'variant': <variant name>,
+      'shards': <number of shards>,
+    },
+    ...
+  ],
+  ...
+}
+```
+The `<buildername>` is a string name of the builder to execute the tests.
+`<test-spec name>` is a label defining a test specification matching the
+[infra-side](https://chromium.googlesource.com/chromium/tools/build/+/master/scripts/slave/recipe_modules/v8/testing.py#58).
+The `<variant name>` is a testing variant as specified in
+`v8/tools/testrunner/local/variants.py`. `<number of shards>` is optional
+(default 1), but can be provided to increase the swarming shards for
+long-running tests.
+
+Example:
+```
+{
+  'v8_linux64_rel_ng_triggered': [
+    {'name': 'v8testing', 'variant': 'nooptimization', 'shards': 2},
+  ],
+}
+```
+
+## Guidelines
+
+Please keep trybots and continuous bots in sync. E.g. add the same configuration
+for the release and debug CI bots and the corresponding trybot (where
+applicable). E.g.
+
+```
+tryserver.v8:
+  v8_linux64_rel_ng_triggered
+client.v8:
+  V8 Linux64
+  V8 Linux64 - debug
+```
