+# Apache SkyWalking committer
+SkyWalking Project Management Committee(PMC) takes the responsibilities to assess the contributions of candidates.
+
+In the SkyWalking, like many Apache projects, we treat contributions including, but not limited to, code contributions.
+Such as writing blog, guiding new users, give public speak, prompting project in various ways, are all treated as significant 
+contributions.
+
+## Committer
+### New committer nomination
+In the SkyWalking, **new committer nomination** could only be started by existing PMC members officially. The new contributor
+could contact any existing PMC member if he/she feels he/she is qualified. Talk with the PMC member, if some members agree,
+they could start the process.
+
+The following steps are recommended, and could only be started by existing PMC member.
+1. Send the `[DISCUSS] Promote xxx as new committer` mail to `private@skywalking.a.o`. List the important contributions of the candidates,
+in order to help the PMC members supporting your proposal.
+2. Keep discussion open in more than 3 days, but not more than 1 week, unless there is any explicit objection or concern.
+3. Send the `[VOTE] Promote xxx as new committer` mail to `private@skywalking.a.o`, when the PMC seems to agree the proposal.
+4. Keep vote more than 3 days, but not more than 1 week. Consider the result as `Consensus Approval` if there 3 +1 votes and
++1 votes > -1 votes
+5. Send the `[RESULT][VOTE] Promote xxx as new committer` mail to `private@skywalking.a.o`, and list the vote detail including
+the voters.
+
+### Invite new committer
+The PMC member, who start the promotion, takes the responsibilities to send the invitation to new committer and guide him/her to set
+up the ASF env.
+
+You should send the mail like the following template to new committer
+```
+To: JoeBloggs@foo.net
+Cc: private@skywalking.apache.org
+Subject: Invitation to become SkyWalking committer: Joe Bloggs
+
+Hello [invitee name],
+
+The SkyWalking Project Management Committee] (PMC) 
+hereby offers you committer privileges to the project . These privileges are
+offered on the understanding that you'll use them
+reasonably and with common sense. We like to work on trust
+rather than unnecessary constraints.
+
+Being a committer enables you to more easily make 
+changes without needing to go through the patch 
+submission process. 
+
+Being a committer does not require you to 
+participate any more than you already do. It does 
+tend to make one even more committed.  You will 
+probably find that you spend more time here.
+
+Of course, you can decline and instead remain as a 
+contributor, participating as you do now.
+
+A. This personal invitation is a chance for you to 
+accept or decline in private.  Either way, please 
+let us know in reply to the [private@skywalking.apache.org] 
+address only.
+
+B. If you accept, the next step is to register an iCLA:
+    1. Details of the iCLA and the forms are found 
+    through this link: http://www.apache.org/licenses/#clas
+
+    2. Instructions for its completion and return to 
+    the Secretary of the ASF are found at
+    http://www.apache.org/licenses/#submitting
+
+    3. When you transmit the completed iCLA, request 
+    to notify the Apache SkyWalking and choose a 
+    unique Apache id. Look to see if your preferred 
+    id is already taken at 
+    http://people.apache.org/committer-index.html     
+    This will allow the Secretary to notify the PMC 
+    when your iCLA has been recorded.
+
+When recording of your iCLA is noticed, you will 
+receive a follow-up message with the next steps for 
+establishing you as a committer.
+```
+
+### Invitation acceptance process
+And the new committer should reply the mail to `private@skywalking.apache.org`(Choose `reply all`), and express the will to accept the invitation explicitly.
+Then this invitation will be treated as accepted by project PMC. Of course, the new committer could just say NO, and reject the invitation.
+
+If they accepted, then they need to do the following things.
+1. Make sure they have subscribed the `dev@skywalking.apache.org`. Usually they already have.
+1. Sign the ICLA(Individual Contributor License Agreement), which could be found [here](http://www.apache.org/licenses/contributor-agreements.html#clas).
+1. If you are going to contribute to the project as day job, CCLA  is expected.
+1. About the ICLA sign, you need to print the ICLA, sign it manually(by hand), and scan it as an pdf. 
+1. Choose your Apache ID and fill it into the ICLA, all existing Apache IDs could be found [here](http://people.apache.org/committer-index.html)
+1. Sign the gpg to your icla.pdf.
+1. Send both `icla.pdf` and `icla.pdf.asc` to `secretary@apache.org` and `private@skywalking.apache.org`.
+
+Then the PMC will wait the Apache secretary confirmed the ICLA filed. The new committer and PMC will receive the mail like following
+```
+Dear XXX,
+
+This message acknowledges receipt of your ICLA, which has been filed in the Apache Software Foundation records.
+
+Your account has been requested for you and you should receive email with next steps
+within the next few days (can take up to a week).
+
+Please refer to https://www.apache.org/foundation/how-it-works.html#developers
+for more information about roles at Apache.
+```
+
+If in some case, the account has not be requested(rarely to see), the PMC member should contact the project V.P..
+The V.P. could request through the [Apache Account Submission Helper Form](https://whimsy.apache.org/officers/acreq).
+
+After several days, the new committer will receive the account created mail, as this title, `Welcome to the Apache Software Foundation (ASF)!`.
+At this point, congratulate! You have the official Apache ID.
+
+The PMC member should add the new committer to official committer list through [roster](https://whimsy.apache.org/roster/committee/skywalking). 
+
+### Set up the Apache ID and dev env
+1. Go to [Apache Account Utility Platform](https://id.apache.org/), initial your password, set up your personal mailbox(`Forwarding email address`) 
+and GitHub account(`Your GitHub Username`).
+1. If you want to use `xxx@apache.org` to send mail, you need to use GMail, and following [this guide](https://reference.apache.org/committer/email).
+1. Use [GitBox Account Linking Utility](https://gitbox.apache.org/setup/) to make your GitHub account to join Apache GitHub org.
+Notice, if never got your GitHub invitation? Visit github.com/apache to see if you have an invitation pending. Also, your GitHub MFA Status is required.
+
+If you want others could see you are in the Apache GitHub org, you need to go to [Apache GitHub org people page](https://github.com/orgs/apache/people), 
+search for yourself, and choose `Organization visibility` to `Public`.
+
+### Committer right, duty and responsibility
+SkyWalking project doesn't require the continue contributions after you become a committer, but we hope and truly want you could.
+
+Being a committer, you could
+1. Review and merge the pull request to the master branch in the Apache repo. For new committer, we hope you could request some senior committer to recheck the pull request.
+1. Create and push codes to new branch in the Apache repo.
+1. Follow the [Release process](../How-to-release.md) to process new release. Of course, you need to ask committer team
+to confirm it is the right time to release.
+
+The PMC hope the new committer to take part in the release and release vote, even still be consider `+1 no binding`.
+But be familiar with the release is one of the key to be promoted as a PMC member.
+
+## Project Management Committee
+Project Management Committee(PMC) member has no special rights in code contributions. 
+They just cover and make sure the project following the Apache requirement, 
+including 
+1. Release binding vote and license check
+1. New committer and PMC member recognition
+1. Identify branding issue and do branding protection.
+1. Response the ASF board question, take necessary actions.
+
+V.P. and chair of the PMC is the secretary, take responsibility of initializing the board report.
+
+In the normal case, the new PMC member should be nominated from committer team. But this is forbidden, if the PMC could
+agree and be confidence that the candidate is ready, such as he/she has been a PMC member of another project, Apache member
+or Apache officer.
+
+The process of new PMC vote should also follow the same `[DISCUSS]`, `[VOTE]` and `[RESULT][VOTE]` in private mail list as [new committer vote](#new-committer-nomination).
+One more step before sending the invitation, the PMC [need to send NOTICE mail to Apache board](http://www.apache.org/dev/pmc.html#newpmc).
+```
+To: board@apache.org
+Cc: private@skywalking.apache.org
+Subject: [NOTICE] Jane Doe for SkyWalking PMC
+
+SkyWalking proposes to invite Jane Doe (janedoe) to join the PMC.
+
+(include if a vote was held) The vote result is available here: https://lists.apache.org/...
+```
+
+After 72 hours, if the board doesn't object(usually it wouldn't be), send the invitation.
+
+After the committer accepted the invitation, 
+The PMC member should add the new committer to official PMC list through [roster](https://whimsy.apache.org/roster/committee/skywalking).
