+Common Cure Rights Commitment
+Version 1.0
+
+Before filing or continuing to prosecute any legal proceeding or claim
+(other than a Defensive Action) arising from termination of a Covered
+License, we commit to extend to the person or entity ('you') accused
+of violating the Covered License the following provisions regarding
+cure and reinstatement, taken from GPL version 3. As used here, the
+term 'this License' refers to the specific Covered License being
+enforced.
+
+    However, if you cease all violation of this License, then your
+    license from a particular copyright holder is reinstated (a)
+    provisionally, unless and until the copyright holder explicitly
+    and finally terminates your license, and (b) permanently, if the
+    copyright holder fails to notify you of the violation by some
+    reasonable means prior to 60 days after the cessation.
+
+    Moreover, your license from a particular copyright holder is
+    reinstated permanently if the copyright holder notifies you of the
+    violation by some reasonable means, this is the first time you
+    have received notice of violation of this License (for any work)
+    from that copyright holder, and you cure the violation prior to 30
+    days after your receipt of the notice.
+
+We intend this Commitment to be irrevocable, and binding and
+enforceable against us and assignees of or successors to our
+copyrights.
+
+Definitions
+
+'Covered License' means the GNU General Public License, version 2
+(GPLv2), the GNU Lesser General Public License, version 2.1
+(LGPLv2.1), or the GNU Library General Public License, version 2
+(LGPLv2), all as published by the Free Software Foundation.
+
+'Defensive Action' means a legal proceeding or claim that We bring
+against you in response to a prior proceeding or claim initiated by
+you or your affiliate.
+
+'We' means each contributor to this repository as of the date of
+inclusion of this file, including subsidiaries of a corporate
+contributor.

+# GlusterFS project Contribution guidelines
+
+## Development Workflow
+
+We follow most of the details as per the [document here](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests). If you are not aware of the github workflow, it is recommended to go through them before continuing here.
+
+
+#### Get the Repository setup
+
+0. Fork Repository
+   - Fork [GlusterFS repository](https://github.com/gluster/glusterfs/fork).
+
+1. Clone Repository
+   - Clone the glusterfs repo freshly from github using below steps.
+
+```
+   git clone git@github.com:${username}/glusterfs.git
+   cd glusterfs/
+   git remote add upstream git@github.com:gluster/glusterfs.git
+```
+
+About two tasks are one time for the life time. You can continue to use the same repository for all the work in future.
+
+#### Development & Other flows
+
+0. Issue:
+   - Make sure there is an issue filed for the task you are working on.
+   - If it is not filed, open the issue with all the description.
+   - If it is a bug fix, add label "Type:Bug".
+   - If it is an RFC, provide all the documentation, and request for "DocApproved", and "SpecApproved" label.
+
+1. Code:
+   - Start coding
+   - Build and test locally
+   - Make sure clang-format is installed and is run on the patch.
+
+2. Keep up-to-date
+   - GlusterFS is a large project with many developers, so there would be one or the other patch everyday.
+   - It is critical for developer to be up-to-date with `devel` repo to be Conflict-Free when PR is opened.
+   - Git provides many options to keep up-to-date, below is one of them
+```
+   git fetch upstream
+   git rebase upstream/devel
+```
+   - It is recommended you keep pushing to your repo every day, so you don't loose any work.
+     - It can be done by `./rfc.sh` (or `git push origin HEAD:issueNNN`)
+
+2. Commit Message / PR description:
+   - The name of the branch on your personal fork can start with issueNNNN, followed by anything of your choice.
+   - PRs continue to have the title of format "component: \<title\>", like it is practiced now.
+   - When you open a PR, having a reference Issue for the commit is mandatory in GlusterFS.
+   - Commit message can have, either `Fixes: #NNNN` or `Updates: #NNNN` in a separate line in the commit message.
+     - Here, NNNN is the Issue ID in glusterfs repository.
+   - Each commit needs the author to have the "Signed-off-by: Name \<email\>" line.
+     - Can do this by `-s` option for `git commit`.
+   - If the PR is not ready for review, apply the label `work-in-progress`.
+     - Check the availability of "Draft PR" is present for you, if yes, use that instead.
+
+3. Tests:
+   - All the required smoke tests would be auto-triggered.
+     - Developers get a chance to retrigger the smoke tests using **"/recheck smoke"** as comment.
+   - The "regression" tests would be triggered by a comment **"/run regression"** from developers in the [@gluster-maintainers](https://github.com/orgs/gluster/teams/gluster-maintainers) group.
+     - Ask for help as comment in PR if you have any questions about the process!
+
+4. Review Process:
+   - `+2` : is equivalent to "Approve" from the people in the maintainer's group.
+   - `+1` : can be given by a maintainer/reviewer by explicitly stating that in the comment.
+   - `-1` : provide details on required changes and pick "Request Changes" while submitting your review.
+   - `-2` : done by adding the `DO-NOT-MERGE` label.
+
+   - Any further discussions can happen as comments in the PR.
+
+5. Making changes:
+   - There are 2 approaches to submit changes done after addressing review comments.
+     - Commit changes as a new commit on top of the original commits in the branch, and push the changes to same branch (issueNNNN)
+     - Commit changes into the same commit with `--amend` option, and do a push to the same branch with `--force` option.
+
+6. Merging:
+   - GlusterFS project follows 'Squash and Merge' method
+     - This is mainly to preserve the historic Gerrit method of one patch in `git log` for one URL link.
+     - This also makes every merge a complete patch, which has passed all tests.
+   - The merging of the patch is expected to be done by the maintainers.
+     - It can be done when all the tests (smoke and regression) pass.
+     - When the PR has 'Approved' flag from corresponding maintainer.
+   - If you feel there is delay, feel free to add a comment, discuss the same in Slack channel, or send email.

+# Gluster
+  Gluster is a software defined distributed storage that can scale to several
+  petabytes. It provides interfaces for object, block and file storage.
 
-*GlusterFS does not follow the [GitHub: Fork & pull](https://help.github.com/articles/using-pull-requests/) workflow but use [Gerrit](http://review.gluster.org) for code review.*
+## Development
+  The development workflow is documented in [Contributors guide](CONTRIBUTING.md)
 
-The development guidelines are detailed in [Development Workflow.](http://www.gluster.org/community/documentation/index.php/Simplified_dev_workflow)
+## Documentation
+  The Gluster documentation can be found at [Gluster Docs](http://docs.gluster.org).
 
-The GlusterFS documentation can be found at [Documentation](http://gluster.readthedocs.org/en/latest)
+## Deployment
+  Quick instructions to build and install can be found in [INSTALL](INSTALL) file.
 
-For more info, please visit http://www.gluster.org/.
+## Testing
+
+  GlusterFS source contains some functional tests under `tests/` directory. All
+  these tests are run against every patch submitted for review. If you want your
+  patch to be tested, please add a `.t` test file as part of your patch submission.
+  You can also submit a patch to only add a `.t` file for the test case you are
+  aware of.
+
+  To run these tests, on your test-machine, just run `./run-tests.sh`. Don't run
+  this on a machine where you have 'production' glusterfs is running, as it would
+  blindly kill all gluster processes in each runs.
+
+  If you are sending a patch, and want to validate one or few specific tests, then
+  run a single test by running the below command.
+
+```
+  bash# /bin/bash ${path_to_gluster}/tests/basic/rpc-coverage.t
+```
+
+  You can also use `prove` tool if available in your machine, as follows.
+
+```
+  bash# prove -vmfe '/bin/bash' ${path_to_gluster}/tests/basic/rpc-coverage.t
+```
+

-/* NOTE: Rules for message additions
- * 1) Each instance of a message is _better_ left with a unique message ID, even
- *    if the message format is the same. Reasoning is that, if the message
- *    format needs to change in one instance, the other instances are not
- *    impacted or the new change does not change the ID of the instance being
- *    modified.
- * 2) Addition of a message,
- *       - Should increment the GLFS_NUM_MESSAGES
- *       - Append to the list of messages defined, towards the end
- *       - Retain macro naming as glfs_msg_X (for redability across developers)
- * NOTE: Rules for message format modifications
- * 3) Check acorss the code if the message ID macro in question is reused
- *    anywhere. If reused then then the modifications should ensure correctness
- *    everywhere, or needs a new message ID as (1) above was not adhered to. If
- *    not used anywhere, proceed with the required modification.
- * NOTE: Rules for message deletion
- * 4) Check (3) and if used anywhere else, then cannot be deleted. If not used
- *    anywhere, then can be deleted, but will leave a hole by design, as
- *    addition rules specify modification to the end of the list and not filling
- *    holes.
+/* To add new message IDs, append new identifiers at the end of the list.
+ *
+ * Never remove a message ID. If it's not used anymore, you can rename it or
+ * leave it as it is, but not delete it. This is to prevent reutilization of
+ * IDs by other messages.
+ *
+ * The component name must match one of the entries defined in
+ * glfs-message-id.h.

- * syncop_xxx() calls are executed in two ways, one is inside a synctask where
- * the executing function will do 'swapcontext' and the other is without
- * synctask where the executing thread is made to wait using pthread_cond_wait.
- * Executing thread may change when syncop_xxx() is executed inside a synctask.
- * This leads to errno_location change i.e. errno may give errno of
- * non-executing thread. So errno is not touched inside a synctask execution.
- * All gfapi calls are executed using the second way of executing syncop_xxx()
- * where the executing thread waits using pthread_cond_wait so it is ok to set
- * errno in these cases. The following macro makes syncop_xxx() behave just
- * like a system call, where -1 is returned and errno is set when a failure
- * occurs.

-dnl @synopsis AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEADERS-TO-CHECK])]
-dnl
-dnl the "ISO C9X: 7.18 Integer types <stdint.h>" section requires the
-dnl existence of an include file <stdint.h> that defines a set of 
-dnl typedefs, especially uint8_t,int32_t,uintptr_t.
-dnl Many older installations will not provide this file, but some will
-dnl have the very same definitions in <inttypes.h>. In other enviroments
-dnl we can use the inet-types in <sys/types.h> which would define the
-dnl typedefs int8_t and u_int8_t respectivly.
-dnl
-dnl This macros will create a local "_stdint.h" or the headerfile given as 
-dnl an argument. In many cases that file will just "#include <stdint.h>" 
-dnl or "#include <inttypes.h>", while in other environments it will provide 
-dnl the set of basic 'stdint's definitions/typedefs: 
-dnl   int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t
-dnl   int_least32_t.. int_fast32_t.. intmax_t
-dnl which may or may not rely on the definitions of other files,
-dnl or using the AC_CHECK_SIZEOF macro to determine the actual
-dnl sizeof each type.
-dnl
-dnl if your header files require the stdint-types you will want to create an
-dnl installable file mylib-int.h that all your other installable header
-dnl may include. So if you have a library package named "mylib", just use
-dnl      AX_CREATE_STDINT_H(mylib-int.h) 
-dnl in configure.ac and go to install that very header file in Makefile.am
-dnl along with the other headers (mylib.h) - and the mylib-specific headers
-dnl can simply use "#include <mylib-int.h>" to obtain the stdint-types.
-dnl
-dnl Remember, if the system already had a valid <stdint.h>, the generated
-dnl file will include it directly. No need for fuzzy HAVE_STDINT_H things...

- * Use at your own risk.  As of February 1996, the committee is squarely
- * behind the fixed sized types; the "least" and "fast" types are still being
- * discussed.  The probability that the "fast" types may be removed before
- * the standard is finalized is high enough that they are not currently
- * implemented.
