+
+## Manifest File to Control the Build/Test apps
+
+`.build-test-rules.yml` file is a manifest file to control if the CI is running the build and test job or not. The Supported Targets table in `README.md` for apps would be auto-generated by `pre-commit` from the app's `.build-test-rules.yml`.
+
+### Grammar
+
+#### Operands
+
+- Variables start with `SOC_`. The value would be parsed from components/soc/[TARGET]/include/soc/*_caps.h
+- `IDF_TARGET`
+- `INCLUDE_DEFAULT` (The default value of officially supported targets is 1, otherwise is 0)
+- String, must be double-quoted. e.g. `"esp32"`, `"12345"`
+- Integer, support decimal and hex. e.g. `1`, `0xAB`
+- List with String and Integer inside, the type could be mixed. e.g. `["esp32", 1]`
+
+#### Operators
+
+- `==`, `!=`, `>`, `>=`, `<`, `<=`
+- `and`, `or`
+- `in`, `not in` with list
+- parentheses
+
+#### Limitation:
+
+- all operators are binary operator. For more than two operands, you may use nested parentheses trick. For example,
+  - `A == 1 or (B == 2 and C in [1,2,3])`
+  - `(A == 1 and B == 2) or (C not in ["3", "4", 5])`
+
+### How does it work?
+
+By default, we enable build and test jobs for supported targets. In other words, if an app supports all supported targets, it does not need to be added in a manifest file. The manifest files are files that set the violation rules for apps.
+
+three rules (disable rules are calculated after the `enable` rule):
+- enable: run CI build/test jobs for targets that match any of the specified conditions only
+- disable: will not run CI build/test jobs for targets that match any of the specified conditions
+- disable_test: will not run CI test jobs for targets that match any of the specified conditions
+
+Each key is a test folder. Will apply to all folders inside.
+
+If one sub folder is in a special case, you can overwrite the rules for this folder by adding another entry for this folder itself. Each folder's rules are standalone, and will not inherit its parent's rules. (YAML inheritance is too complicated for reading)
+
+For example in the following codeblock, only `disable` rule exists in `examples/foo/bar`. It's unaware of its parent's `enable` rule. 
+
+```yaml
+examples/foo:
+  enable:
+    - if: IDF_TARGET == "esp32"
+
+examples/foo/bar:
+  disable:
+    - if: IDF_TARGET == "esp32s2"
+```
+
+### Example
+
+```yaml
+examples/foo:
+  enable:
+    - if IDF_TARGET in ["esp32", 1, 2, 3]
+    - if IDF_TARGET not in ["4", "5", 6]
+  # should be run under all targets!
+
+examples/bluetooth:
+  disable:  # disable both build and tests jobs
+    - if: SOC_BT_SUPPORTED != 1
+    # reason is optional if there's no `temporary: true`
+  disable_test:
+    - if: IDF_TARGET == "esp32"
+      temporary: true
+      reason: lack of ci runners  # required when `temporary: true`
+
+examples/bluetooth/test_foo:
+  # each folder's settings are standalone
+  disable:
+    - if: IDF_TARGET == "esp32s2"
+      temporary: true
+      reason: no idea
+  # unlike examples/bluetooth, the apps under this folder would not be build nor test for "no idea" under target esp32s2
+
+examples/get-started/hello_world:
+  enable:
+    - if: IDF_TARGET == "linux"
+      reason: this one only supports linux!
+
+examples/get-started/blink:
+  enable:
+    - if: INCLUDE_DEFAULT == 1 or IDF_TARGET == "linux"
+      reason: This one supports all supported targets and linux
