 * 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 <http://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.

-### Non-GitHub forks
-
-ESP-IDF uses relative locations as its submodules URLs ([.gitmodules](.gitmodules)). So they link to GitHub.
-If ESP-IDF is forked to a Git repository which is not on GitHub, you will need to run the script
-[tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh) after git clone.
-The script sets absolute URLs for all submodules, allowing `git submodule update --init --recursive` to complete.
-If cloning ESP-IDF from GitHub, this step is not needed.

-The latest support policy for ESP-IDF can be found at [https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md](https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md)
-
-Support Period Policy
-=====================
-
-Each ESP-IDF major and minor release (V4.0, V4.1, etc) is supported for
-18 months after the initial stable release date.
-
-Supported means that the ESP-IDF team will continue to apply bug fixes,
-security fixes, etc to the release branch on GitHub, and periodically
-make new bugfix releases as needed.
-
-Users are encouraged to upgrade to a newer ESP-IDF release before the
-support period finishes and the release becomes End of Life (EOL). It is
-our policy to not continue fixing bugs in End of Life releases.
-
-Pre-release versions (betas, previews, `-rc` and `-dev` versions, etc)
-are not covered by any support period. Sometimes a particular feature is
-marked as \"Preview\" in a release, which means it is also not covered
-by the support period.
-
-The ESP-IDF Programming Guide has information about the
-[different versions of ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/versions.html)
-(major, minor, bugfix, etc).
-
-Long Term Support releases
---------------------------
-
-Some releases (starting with ESP-IDF V3.3) are designated Long Term
-Support (LTS). LTS releases are supported for 30 months (2.5 years)
-after the initial stable release date.
-
-A new LTS release will be made at least every 18 months. This means
-there will always be a period of at least 12 months to upgrade from the
-previous LTS release to the following LTS release.
-
-Example
--------
-
-ESP-IDF V3.3 was released in September 2019 and is a Long Term Support
-(LTS) release, meaning it will be supported for 30 months until February
-2022.
-
-- The first V3.3 release was `v3.3` in September 2019.
-- The ESP-IDF team continues to backport bug fixes, security fixes,
-  etc to the release branch `release/v3.3`.
-- Periodically stable bugfix releases are created from the release
-  branch. For example `v3.3.1`, `v3.3.2`, etc. Users are encouraged to
-  always update to the latest bugfix release.
-- V3.3 bugfix releases continue until February 2022, when all V3.3.x
-  releases become End of Life.
-
-Existing Releases
------------------
-
-ESP-IDF release V3.3 and all newer releases will follow this support
-period policy.  The support period for each release will be announced
-when the release is made.
-
-For releases made before the support period policy was announced,
-the following support periods apply:
-
-- ESP-IDF V3.1.x and V3.2.x will both be supported until October 2020.
-- ESP-IDF V3.0.9 (planned for October 2019) will be the last V3.0
-  bugfix release. ESP-IDF V3.0.x is End of Life from October 2019.
-- ESP-IDF versions before V3.0 are already End of Life.

-// Target is not allowed to perform other RTT operations while string still has not been stored completely.
-// Otherwise we would probably end up with a mixed string in the buffer.
-// If using  RTT from within interrupts, multiple tasks or multi processors, define the SEGGER_RTT_LOCK() and SEGGER_RTT_UNLOCK() function here.
-//
-// SEGGER_RTT_MAX_INTERRUPT_PRIORITY can be used in the sample lock routines on Cortex-M3/4.
-// Make sure to mask all interrupts which can send RTT data, i.e. generate SystemView events, or cause task switches.
-// When high-priority interrupts must not be masked while sending RTT data, SEGGER_RTT_MAX_INTERRUPT_PRIORITY needs to be adjusted accordingly.
-// (Higher priority = lower priority number)
-// Default value for embOS: 128u
-// Default configuration in FreeRTOS: configMAX_SYSCALL_INTERRUPT_PRIORITY: ( configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY << (8 - configPRIO_BITS) )
-// In case of doubt mask all interrupts: 1 << (8 - BASEPRI_PRIO_BITS) i.e. 1 << 5 when 3 bits are implemented in NVIC
-// or define SEGGER_RTT_LOCK() to completely disable interrupts.
-//
-
-#define SEGGER_RTT_MAX_INTERRUPT_PRIORITY         (0x20)   // Interrupt priority to lock on SEGGER_RTT_LOCK on Cortex-M3/4 (Default: 0x20)
