-parts. 
-
-9. ENTIRE AGREEMENT. This agreement, and any other terms Microsoft may provide for

-shall control. 
-
-10. APPLICABLE LAW AND PLACE TO RESOLVE DISPUTES. If you acquired the software in
-the United States or Canada, the laws of the state or province where you live
-(or, if a business, where your principal place of business is located) govern
-the interpretation of this agreement, claims for its breach, and all other
-claims (including consumer protection, unfair competition, and tort claims),
-regardless of conflict of laws principles. If you acquired the software in any
-other country, its laws apply. If U.S. federal jurisdiction exists, you and
-Microsoft consent to exclusive jurisdiction and venue in the federal court in
-King County, Washington for all disputes heard in court. If not, you and
-Microsoft consent to exclusive jurisdiction and venue in the Superior Court of
-King County, Washington for all disputes heard in court. 
-
-11. CONSUMER RIGHTS; REGIONAL VARIATIONS. This agreement describes certain legal
-rights. You may have other rights, including consumer rights, under the laws of
-your state or country. Separate and apart from your relationship with Microsoft,
-you may also have rights with respect to the party from which you acquired the
-software. This agreement does not change those other rights if the laws of your
-state or country do not permit it to do so. For example, if you acquired the
-software in one of the below regions, or mandatory country law applies, then the
-following provisions apply to you: 
-
-a) Australia. You have statutory guarantees under the Australian Consumer Law and
-nothing in this agreement is intended to affect those rights. 
-
-b) Germany and Austria. 
-
-i. Warranty. The properly licensed software will perform substantially as
-described in any Microsoft materials that accompany the software. However,
-Microsoft gives no contractual guarantee in relation to the licensed software. 
-
-ii. Limitation of Liability. In case of intentional conduct, gross negligence,
-claims based on the Product Liability Act, as well as, in case of death or
-personal or physical injury, Microsoft is liable according to the statutory law.
-
-
-Subject to the foregoing clause ii., Microsoft will only be liable for slight
-negligence if Microsoft is in breach of such material contractual obligations,
-the fulfillment of which facilitate the due performance of this agreement, the
-breach of which would endanger the purpose of this agreement and the compliance
-with which a party may constantly trust in (so-called "cardinal obligations").
-In other cases of slight negligence, Microsoft will not be liable for slight
-negligence. 
-
-12. DISCLAIMER OF WARRANTY. THE SOFTWARE IS LICENSED “AS IS.” YOU BEAR THE RISK OF
-USING IT. MICROSOFT GIVES NO EXPRESS WARRANTIES, GUARANTEES, OR CONDITIONS. TO
-THE EXTENT PERMITTED UNDER APPLICABLE LAWS, MICROSOFT EXCLUDES ALL IMPLIED
-WARRANTIES, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND
-NON-INFRINGEMENT. 
-
-13. LIMITATION ON AND EXCLUSION OF DAMAGES. IF YOU HAVE ANY BASIS FOR RECOVERING
-DAMAGES DESPITE THE PRECEDING DISCLAIMER OF WARRANTY, YOU CAN RECOVER FROM
-MICROSOFT AND ITS SUPPLIERS ONLY DIRECT DAMAGES UP TO U.S. $5.00. YOU CANNOT
-RECOVER ANY OTHER DAMAGES, INCLUDING CONSEQUENTIAL, LOST PROFITS, SPECIAL,
-INDIRECT, OR INCIDENTAL DAMAGES. 
-
-This limitation applies to (a) anything related to the software, services,
-content (including code) on third party Internet sites, or third party
-applications; and (b) claims for breach of contract, warranty, guarantee, or
-condition; strict liability, negligence, or other tort; or any other claim; in
-each case to the extent permitted by applicable law. 
-
-It also applies even if Microsoft knew or should have known about the
-possibility of the damages. The above limitation or exclusion may not apply to
-you because your state, province, or country may not allow the exclusion or
-limitation of incidental, consequential, or other damages. 
-
- 
-
-Please note: As this software is distributed in Canada, some of the clauses in
-this agreement are provided below in French. 
-
-Remarque: Ce logiciel étant distribué au Canada, certaines des clauses dans ce
-contrat sont fournies ci-dessous en français. 
-
-EXONÉRATION DE GARANTIE. Le logiciel visé par une licence est offert « tel quel
-». Toute utilisation de ce logiciel est à votre seule risque et péril. Microsoft
-n’accorde aucune autre garantie expresse. Vous pouvez bénéficier de droits
-additionnels en vertu du droit local sur la protection des consommateurs, que ce
-contrat ne peut modifier. La ou elles sont permises par le droit locale, les
-garanties implicites de qualité marchande, d’adéquation à un usage particulier

-## Documentation
+![ThreadX Key Features](./docs/threadx-features.png)
 
-Documentation for this library can be found here: http://docs.microsoft.com/azure/rtos/threadx
+## Getting Started
 
+Eclipse ThreadX has been integrated to the semiconductor's SDKs and development environment. You can develop using the tools of choice from [STMicroelectronics](https://www.st.com/content/st_com/en/campaigns/x-cube-azrtos-azure-rtos-stm32.html), [NXP](https://www.nxp.com/design/software/embedded-software/azure-rtos-for-nxp-microcontrollers:AZURE-RTOS), [Renesas](https://github.com/renesas/azure-rtos) and [Microchip](https://mu.microchip.com/get-started-simplifying-your-iot-design-with-azure-rtos).
 
-# Understanding inter-component dependencies
+We also provide [getting started guide](https://github.com/eclipse-threadx/getting-started) and [samples](https://github.com/eclipse-threadx/samples) using development boards from semiconductors you can build and test with.
 
-The main components of Azure RTOS are each provided in their own repository, but there are dependencies between them--shown in the following graph--that are important to understand when setting up your builds.
+See [Overview of Eclipse ThreadX RTOS](https://github.com/eclipse-threadx/rtos-docs/blob/main/rtos-docs/threadx/overview-threadx.md) for the high-level overview.

-## Prerequisites
-
-Install the following tools:
-
-* [CMake](https://cmake.org/download/) version 3.0 or later
-* [GCC compilers for arm-none-eabi](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
-* [Ninja](https://ninja-build.org/)
-
-## Cloning the repo
-
-```bash
-$ git clone https://github.com/azure-rtos/threadx.git
-```
-
-## Building as a static library
-
-Each component of Azure RTOS comes with a composible CMake-based build system that supports many different MCUs and host systems. Integrating any of these components into your device app code is as simple as adding a git submodule and then including it in your build using the CMake command `add_subdirectory()`.
-
-While the typical usage pattern is to include threadx into your device code source tree to be built & linked with your code, you can compile this project as a standalone static library to confirm your build is set up correctly.
-
-```bash
-$ cmake -Bbuild -DCMAKE_TOOLCHAIN_FILE=cmake/cortex_m4.cmake -GNinja .
-
-$ cmake --build ./build
-```
-
-NOTE: You will have to take the dependency graph above into account when building anything other than threadx itself.

-## Reporting Security Issues
+## Reporting a Vulnerability
 
-**Please do not report security vulnerabilities through public GitHub issues.**
+If you think you have found a vulnerability in <project> you can report it using one of the following ways:
 
-Instead, please report them to the Microsoft Security Response Center (MSRC) at [https://msrc.microsoft.com/create-report](https://msrc.microsoft.com/create-report).
+* Contact the [Eclipse Foundation Security Team](mailto:security@eclipse-foundation.org)
+* [Report a Vulnerability](https://github.com/eclipse-threadx/threadx/security/advisories/new)
 
-If you prefer to submit without logging in, send email to [secure@microsoft.com](mailto:secure@microsoft.com).  If possible, encrypt your message with our PGP key; please download it from the the [Microsoft Security Response Center PGP Key page](https://www.microsoft.com/en-us/msrc/pgp-key-msrc).
+You can find more information about reporting and disclosure at the [Eclipse Foundation Security page](https://www.eclipse.org/security/).
 
-You should receive a response within 24 hours. If for some reason you do not, please follow up via email to ensure we received your original message. Additional information can be found at [microsoft.com/msrc](https://www.microsoft.com/msrc).
+## Security Policy
 
-Please include the requested information listed below (as much as you can provide) to help us better understand the nature and scope of the possible issue:
+This project follows [Eclipse Foundation Vulnerability Reporting Policy](https://www.eclipse.org/security/policy/).
-
-  * Type of issue (e.g. buffer overflow, SQL injection, cross-site scripting, etc.)
-  * Full paths of source file(s) related to the manifestation of the issue
-  * The location of the affected source code (tag/branch/commit or direct URL)
-  * Any special configuration required to reproduce the issue
-  * Step-by-step instructions to reproduce the issue
-  * Proof-of-concept or exploit code (if possible)
-  * Impact of the issue, including how an attacker might exploit the issue
-
-This information will help us triage your report more quickly.
-
-## Preferred Languages
-
-We prefer all communications to be in English.
