Proposed change

Since we have no requirement about using rebase or on PR branches history (since we squash-merge), contributors can also use git merge. This adds instructions for that as it is easier to use than rebase and also so that it does not look like rebase is a requirement for contributors.

Type of change

  • Document existing features within Home Assistant
  • Document new or changing features which there is an existing pull request elsewhere
  • Spelling or grammatical corrections, or rewording for improved clarity
  • Changes to the backend of this documentation
  • Removed stale or deprecated documentation

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>, please review it.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

5-5: Improve clarity by fronting the goal

Per style guidelines, restructure the sentence to front the goal:

-If it's taking a while to develop your feature, and you want to catch up with what's in the current Home Assistant `dev` branch, you can either use `git merge` or `git rebase`.
+To synchronize your feature branch with the current Home Assistant `dev` branch, use either `git merge` or `git rebase`.

7-7: Remove redundant wording

-You should have added an additional `remote` after you clone your fork. If you did not, do it now before proceeding:
+You should have added a `remote` after cloning your fork. If you did not, do it now before proceeding:

17-23: Improve clarity of merge instructions

The instructions are correct but could be more direct per style guidelines:

-This will pull the latest Home Assistant changes locally, and merge them into your branch by creating a merge commit.
+Merge the latest Home Assistant changes into your branch by creating a merge commit:

38-44: Improve clarity of error handling instructions

The error handling section could be more direct and clearer:

-If that command fails, it means that new work was pushed to the branch from either you or another contributor since your last update. In that case, just pull them into your local branch, solve any conflicts and push everything again:
+If the push fails due to new remote changes, pull the changes, resolve any conflicts, and push again:

48-49: Simplify the rebase explanation

The explanation could be more direct per style guidelines:

-This will pull the latest Home Assistant changes locally, rewind your commits, bring in the latest changes from Home Assistant, and replay all of your commits on top.
+Rebase replays your changes on top of the latest Home Assistant changes, maintaining a linear history.

Line range hint 5-89: Documentation changes look good!

The documentation successfully introduces git merge as an alternative to rebase, with clear instructions for both workflows. The structure is logical, and important warnings are properly highlighted.

My take is that there should be a single simple, opinionated, recommendation here and not multiple. My assumption is that the target person reading this is a new developer who may be learning git and using it for the first time in this project. Additional options may be overwhelming.

My other assumption would be that if folks that are familiar enough with git to understand the differences between these two paths, they should be able to navigate how to use each of them.

(This is just my 2 cents as a non-advanced git user. Reading this page a few years ago was one of the first times I really used git to contribute to a project from a branch)
