-## 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

+Contributions Guide
+===================
+
+We welcome contributions to the esp-idf project!
+
+How to Contribute
+-----------------
+
+Contributions to esp-idf - fixing bugs, adding features, adding documentation - are welcome. We accept contributions via `Github Pull Requests <https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests>`_.
+
+Before Contributing
+-------------------
+
+Before sending us a Pull Request, please consider this list of points:
+
+* Is the contribution entirely your own work, or already licensed under an Apache License 2.0 compatible Open Source License? If not then we unfortunately cannot accept it.
+
+* Does any new code conform to the esp-idf :doc:`Style Guide <style-guide>`?
+
+* Have you installed the :doc:`pre-commit hook <install-pre-commit-hook>` for esp-idf project?
+
+* Does the code documentation follow requirements in :doc:`documenting-code`?
+
+* Is the code adequately commented for people to understand how it is structured?
+
+* Is there documentation or examples that go with code contributions? There are additional suggestions for writing good examples in :idf:`examples` readme.
+
+* Are comments and documentation written in clear English, with no spelling or grammar errors?
+
+* Example contributions are also welcome. Please check the :doc:`creating-examples` guide for these.
+
+* If the contribution contains multiple commits, are they grouped together into logical changes (one major change per pull request)? Are any commits with names like "fixed typo" `squashed into previous commits <https://eli.thegreenplace.net/2014/02/19/squashing-github-pull-requests-into-a-single-commit/>`_?
+
+* If you're unsure about any of these points, please open the Pull Request anyhow and then ask us for feedback.
+
+Pull Request Process
+--------------------
+
+After you open the Pull Request, there will probably be some discussion in the comments field of the request itself.
+
+Once the Pull Request is ready to merge, it will first be merged into our internal git system for in-house automated testing.
+
+If this process passes, it will be merged onto the public github repository.
+
+Legal Part
+----------
+
+Before a contribution can be accepted, you will need to sign our :doc:`contributor-agreement`. You will be prompted for this automatically as part of the Pull Request process.
