-### Issue tracker is for bugs
+### The issue tracker is for bugs, not feature requests
-The main purpose of this issue tracker is to track bugs for the Android client. Relevant, concise and to the point comments that help to solve the issue are very welcome.
+The GitHub issue tracker is not used for feature requests, but new ideas can be submitted and discussed on the [community forum](https://community.signalusers.org/c/feature-requests). The purpose of this issue tracker is to track bugs in the Android client. Bug reports should only be submitted for existing functionality that does not work as intended. Comments that are relevant and concise will help the developers solve issues more quickly.

+### Send support questions to support
-Please do **not** ask support questions at the issue tracker. We want to help you using Signal and we have created our support system just for that. You can reach support by sending email to support@whispersystems.org or by going to our [Support Center](http://support.whispersystems.org). You can also search for existing troubleshooting articles at the [Support Center](http://support.whispersystems.org).
+You can reach support by sending an email to support@signal.org or by visiting the [Signal Support Center](https://support.signal.org/) where you can also search for existing troubleshooting articles and find answers to frequently asked questions. Please do not post support questions on the GitHub issue tracker.
 
-##### Not a discussion forum
+### GitHub is not a generic discussion forum
-Please do **not** use this issue tracker as a discussion forum. Discussion related to the bug in question should of course go to the issue itself. However other discussion should take place at the [community forum](https://whispersystems.discoursehosting.net). You can use that forum to discuss any Signal related topics or to just hang out with your fellow users.
+Conversations about open bug reports belong here. However, all other discussions should take place on the [community forum](https://community.signalusers.org). You can use the community forum to discuss anything that is related to Signal or to hang out with your fellow users in the "Off Topic" category.
 
 ### Don't bump issues
-Every time someone comments on an issue, GitHub sends email to [everyone who is watching](https://github.com/WhisperSystems/Signal-Android/watchers) the repository (currently around 500 people). Thus bumping issues with :+1:s, _me toos_ or asking for updates generates a lot of unnecessary email notifications. Moreover bumping an issue does not help solve it. Please be respectful of everyone's time and only comment if you have relevant new information to add.
+Every time someone comments on an issue, GitHub sends an email to [hundreds of people](https://github.com/signalapp/Signal-Android/watchers). Bumping issues with a "+1" (or asking for updates) generates a lot of unnecessary email notifications and does not help anyone solve the issue any faster. Please be respectful of everyone's time and only comment when you have new information to add.
 
 ### Open issues

+#### If it's open, it's tracked
-Have you followed all the points in the [Submitting useful bug reports guide](https://github.com/WhisperSystems/Signal-Android/wiki/Submitting-useful-bug-reports) but nobody has commented on your issue? Is there no milestone or person assigned to it? Don't worry, the developers read every issue and if it's open it means it's tracked and taken into account. It might just take time as other issues have higher priority. And remember that this is an open source project: Everyone is encouraged to take an active role in fixing open issues.
+The developers read every issue, but high-priority bugs or features can take precedence over others. Signal is an open source project, and everyone is encouraged to play an active role in diagnosing and fixing open issues.
 
 ### Closed issues
 
 #### "My issue was closed without giving a reason!"
-Please understand that writing detailed explanations every time for every issue someone comes up with takes time. Sometimes a reason has been posted earlier to another related issue which you can search for. It's also possible that your issue was not in line with the guidelines of the project (see especially the [Development Ideology](https://github.com/WhisperSystems/Signal-Android/blob/master/CONTRIBUTING.md#development-ideology)), or it was decided that the issue is not something that Signal should do at this time.
+Although we do our best, writing detailed explanations for every issue can be time consuming, and the topic also might have been covered previously in other related issues.
 
 
 ## Pull requests
 
-### Sign the Contributor Licence Agreement (CLA)
+### Smaller is better
-You need to sign our CLA before your pull request can be merged. You can sign it at: https://whispersystems.org/cla/
+Big changes are significantly less likely to be accepted. Large features often require protocol modifications and necessitate a staged rollout process that is coordinated across millions of users on multiple platforms (Android, iOS, and Desktop).

+Try not to take on too much at once. As a first-time contributor, we recommend starting with small and simple PRs in order to become familiar with the codebase. Most of the work should go into discovering which three lines need to change rather than writing the code.
