+有时在你致力于一个较长周期才能完成的分支时，其它人提交的变更会与你提交的pull request中的变更发生冲突。我们将这种多个人编辑同一个模块同一个文件时产生的场景叫做 *合并冲突*
+
+?> 本文中的场景基于[在你Fork的主干上：频繁更新，不要提交](zh-cn/newbs_git_using_your_master_branch.md)一文。如果你对那篇文章不熟悉，请先阅读它，再回来继续。
+
+## 变基/衍合（rebase）
+
+
+Git的*变基*操作会将提交历史中的提交节点摘除并回滚，然后统一提交到一个新节点上。在解决合并冲突时，可以通过对当前分支进行变基，来获取从分支拉取到当前时刻的所有变更。
+
+从执行如下命令开始：
+
+```
+git fetch upstream
+git rev-list --left-right --count HEAD...upstram/master
+```
+
+此处输入的 `git rev-list` 命令可以得到当前分支与QMK主干分支间的提交数量差。而先执行 `git fetch` 是为了确保我们有上游仓库（upstream repo）的最新状态。`git rev-list` 命令会返回两个数字：
+
+```
+$ git rev-list --left-right --count HEAD...upstream/master
+7       35
+```
+
+第一个数字为当前分支自创建后新增的提交数量。第二个数字为当前分支创建后在 `upstream/master` 上的提交数量，而这部分就是我们当前分支上缺失的提交记录。
+
+在我们了解了当前分支以及上游仓库的状态后，可以发起变基操作了：
+
+```
+git rebase upstream/master
+```
+
+这样可以让Git回滚该分支的提交，然后基于QMK的主干版本重新应用这些提交。
+
+*译注：以下内容在中文Git下大同小异，且仅作为示例，不进行翻译*
+```
+$ git rebase upstream/master
+First, rewinding head to replay your work on top of it...
+Applying: Commit #1
+Using index info to reconstruct a base tree...
+M       conflicting_file_1.txt
+Falling back to patching base and 3-way merge...
+Auto-merging conflicting_file_1.txt
+CONFLICT (content): Merge conflict in conflicting_file_1.txt
+error: Failed to merge in the changes.
+hint: Use 'git am --show-current-patch' to see the failed patch
+Patch failed at 0001 Commit #1
+
+Resolve all conflicts manually, mark them as resolved with
+"git add/rm <conflicted_files>", then run "git rebase --continue".
+You can instead skip this commit: run "git rebase --skip".
+To abort and get back to the state before "git rebase", run "git rebase --abort".
+```
+
+以上内容是在告诉我们有合并冲突存在，并给出了冲突所在的文件名。在编辑器中打开该文件，可以在某处发现类似如下形式的内容：
+
+```
+<<<<<<< HEAD
+<p>For help with any issues, email us at support@webhost.us.</p>
+=======
+<p>Need help? Email support@webhost.us.</p>
+>>>>>>> Commit #1
+```
+
+`<<<<<<< HEAD` 标记了合并冲突的起始行，直至 `>>>>>>> Commit #1` 标记的结束行，中间通过 `=======` 分隔开冲突双方。其中 `HEAD` 部分为QMK主干上的版本，标记了提交日志的部分为当前分支的本地提交。
+
+由于Git存储的是*文件差异部分*而非整个文件，所以当Git无法在文件中找到一个变更发生前的内容时，就无法知道如何去进行文件变更，重新编辑一下可以解决问题。在更改完成后，保存文件。
+
+```
+<p>Need help? Email support@webhost.us.</p>
+```
+
+之后，执行：
+
+```
+git add conflicting_file_1.txt
+git rebase --continue
+```
+
+Git即会记录对文件冲突做出的变更，并继续处理剩余的提交，直至全部完成。

+
+## 备份你在自己的主干分支上的所有变更（可选）
+
+不会有人想把有用的成果弄丢的。如果你想将你的 `master` 分支上的变更另存一份，简便的方法是直接创建一个当前“脏” `master` 分支的副本：
+
+```
+git branch old_master master
+```
+
+现在 `master` 分支拥有了一个副本分支 `old_master`。
+
+## 重新同步分支
+
+现在可以重新同步 `master` 分支了，这里，我们将QMK仓库设置为Git的远程仓库。通过执行 `git remote -v` 可以确认远程仓库配置，输出信息应类似于：
+
+```
+QMKuser ~/qmk_firmware (master)
+$ git remote -v
+origin  https://github.com/<your_username>/qmk_firmware.git (fetch)
+origin  https://github.com/<your_username>/qmk_firmware.git (push)
+upstream        https://github.com/qmk/qmk_firmware.git (fetch)
+upstream        https://github.com/qmk/qmk_firmware.git (push)
+```
+
+如果你只能看到一个仓库：
+
+```
+QMKuser ~/qmk_firmware (master)
+$ git remote -v
+origin  https://github.com/qmk/qmk_firmware.git (fetch)
+origin  https://github.com/qmk/qmk_firmware.git (push)
+```
+
+通过如下命令添加新的远程仓库：
+
+```
+git remote add upstream https://github.com/qmk/qmk_firmware.git
+```
+
+然后，重新将 `origin` 远程仓库设置为自己的fork：
+
+```
+git remote set-url origin https://github.com/<your_username>/qmk_firmware.git
+```
+
+在两个远程仓库配置完毕后，需要从QMK的 upstream 仓库中获取到更新，执行：
+
+```
+git fetch upstream
+```
+
+此时，重新同步你的分支到QMK的版本：
+
+```
+git reset --hard upstream/master
+```
+
+以上操作会更新你的本地仓库，而你的Github远程仓库仍然处于未同步状态，通过推送，可以让其进入已同步状态。可以通过如下命令来指引Git强行覆盖掉那些仅在你远程仓库中存在的提交：
+
+```
+git push --force-with-lease
+```
+
+!> **不要**在其它使用者也会提交的分支上执行 `git push --force-with-lease`，否则会覆盖掉他人的提交。
+
+此时你的Github fork，本地文件副本，以及QMK仓库就是一致的了。之后再进行变更（[在分支上！](zh-cn/newbs_git_using_your_master_branch.md#making-changes)）和提交。
