+# Contributing to msm8916-mainline/linux
+Thanks for your interest in contributing to msm8916-mainline/linux! :tada:
+
+## About
+[msm8916-mainline/linux] is a fork of the [mainline Linux kernel](https://kernel.org)
+(released by Linus Torvalds). Goal of the repository is to **temporarily** host
+**work-in-progress** changes for various devices based on the
+Qualcomm Snapdragon 410/412 (MSM8916) SoC.
+
+Once ready, changes should be [submitted upstream](https://www.kernel.org/doc/html/latest/process/submitting-patches.html)
+through the appropriate mailing lists.  
+**Changes submitted in this repository will not automatically land upstream!**
+
+**Note:** This fork is **unofficial** and not (directly) affiliated to the mainline
+Linux project. As such, it is entirely **optional** to submit your changes as
+pull request to this repository. You can also immediately send your changes
+upstream to the appropriate mailing lists. Submitting your changes here (before
+sending them upstream) has the following advantages:
+
+  - **Preliminary review:** You get early feedback on your patches which may
+    speed up submission of your patch upstream later.
+    **Note:** Acceptance of your patch in this repository does not mean that
+    the upstream maintainers will accept it!
+
+  - **Kept up-to-date:** All patches in this repository will be rebased to newer
+    upstream Linux releases, so your device will be always up-to-date even with
+    some work-in-progress changes.
+
+  - **Packaged in [postmarketOS]:** This fork is the source of the
+    `linux-postmarketos-qcom-msm8916` package in postmarketOS, which is used by
+    all MSM8916 devices based on the mainline kernel. Your changes will be
+    included in the next release and therefore show up in postmarketOS.
+
+## Patch Requirements
+Goal for all patches in this repository is to upstream them eventually. Therefore,
+the formal requirements are similar to upstream, e.g.:
+
+  - No compile warnings/errors
+  - Clean code style
+  - Changes separated into clean commits (one per logical change/subsystem)
+  - Appropriate commit message that explains the motivation for the change
+
+If you want to contribute to this repository, you should be willing to bring your
+patches into suitable shape for upstreaming. Most of this is documented upstream
+in [Submitting patches]. Don't worry if you don't get it exactly right the first time. :)
+
+### Sign off your patches - the Developer's Certificate of Origin
+Upstream contributions to the Linux kernel are required to have the following
+tag in the commit message:
+
+```
+Signed-off-by: FirstName LastName <[email protected]>
+```
+
+These tags are also required when contributing to this repository. Reason for
+this is that you might become busy at some point, or your interests change. Then
+it is important that someone else can pick up your work and finish it up.
+
+Please read [Sign your work - the Developer’s Certificate of Origin](https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin)
+**carefully** to understand the meaning of the `Signed-off-by:`.
+It also explains how to add it easily when creating new commits.
+
+## Upstreaming
+Upstreaming changes takes time. And sometimes, changes cannot be submitted
+upstream yet because they are work-in-progress or because there are fundamental
+open problems that cannot be solved immediately, e.g.:
+
+  - Weird issues where the actual cause cannot be determined at the moment ("hacks").
+  - New drivers with problems in some edge cases.
+  - Panel drivers that are mostly auto-generated and that are hard to document
+    properly because of lack of documentation.
+  - Battery/charging drivers that are hard to validate without expert knowledge.
+
+If you have something (mostly) working and the [formal patch requirements](#patch-requirements)
+are met, then it's good to share it with others in this repository.
+
+However, keep in mind that maintaining a large amount of patches in this
+repository consumes a significant amount of time, especially when breaking
+changes are made upstream. This means less time to review new patches
+or to work on improvements everyone can benefit from.
+
+**Please help to keep maintenance time at an acceptable level by submitting your
+patches upstream when they are ready.** If you are not sure if your patches are
+ready, just ask and we can discuss it.
+
+### Patches that touch upstream files
+Patches that touch upstream files which are frequently updated
+(e.g. existing, shared drivers instead of files specific to your device)
+should be submitted upstream before they are merged into this repository.
+This is because those tend to cause conflicts much more frequently when updating
+to newer kernel versions.
+
+This is just a guideline to reduce maintenance, exceptions can be made if necessary.
+
+## Questions
+If you have any questions, feel free to ask in the [postmarketOS mainline channel
+on Matrix or IRC](https://wiki.postmarketos.org/wiki/Matrix_and_IRC).
