+## git-gloss ✨
+
+Annotate git log output with GitHub PR/Issue/Reviewer metadata
+
+### How to run
+
+You can download and run `git-gloss` within a directory having a GitHub repo clone by doing this:
+
+```
+curl -fsSLO https://sideshowbarker.github.io/git-gloss/git-gloss && bash ./git-gloss
+```
+
+That will add [git notes](https://web.archive.org/web/20180121193320/http://git-scm.com/blog/2010/08/25/notes.html) locally for all commits in the local commit history with an associated GitHub pull request.
+
+It can process about 22 commits per minute — or about 1300 commits per hour.
+
+So, the first time you run it in a repo with many commits, it’ll take a long time — hours, or even a day or more.
+
+For example, if your repo has somewhere around 1000 commits, it’ll take about an hour to finish. If your repo has somewhere around 10,000 commits, it’ll take more than 7 hours. And so on.
+
+You can stop `git-gloss` at any time with <kbd>Ctrl</kbd>-<kbd>C</kbd>. After stopping it, when you run it again, it will start off wherever it left off. So for example, if you have a repo with somewhere around 10,000 commits, and you stopped `git-gloss` after it was running for about an hour, then it will run for about another hour before it finishes.
+
+### Sharing the notes
+
+Once `git-gloss` finishes running, here’s how you can share the notes with everyone in your project:
+
+1. Push the notes back to your project remote by running this command:
+
+   ```
+   git push origin 'refs/notes/*'
+   ```
+
+2. Others in your project can then fetch the notes from the remote by running this command:
+
+   ```
+   git fetch origin 'refs/notes/*:refs/notes/*'
+   ```
+
+3. Run `git-gloss` again to add notes for any new commits made after the last time you ran `git-gloss`.
+
+4. Keep your project’s notes up to date by repeating steps 1 to 3 at a regular cadence (e.g., once day or so).
+
+### Dependencies
+
+* `git` – any version with support for the `--no-separator` option for the `git notes` command
+
+* `jq` – https://jqlang.github.io/jq/ (JSON processor)
+
+* `gh` – https://cli.github.com/ (GitHub CLI)
+
+* `grep` – on macOS in particular, a grep program other than the Apple-provided one is recommended (for instance, GNU grep or [ripgrep](https://github.com/BurntSushi/ripgrep#installation)); for example:
+
+  ```
+  brew install ripgrep
+  brew install grep
+  ```
+
+### Environment variables
+
+You can affect the `git-gloss` behavior using the following environment variables:
+
+* `GIT`
+
+  You can use this to specify a path to a different `git` binary — for instance, in the case where you have multiple different `git` versions on your system; example:
+
+  ```
+  export GIT=/opt/homebrew/bin/git
+  ```
+
+* `GREP`
+
+  You can use this to specify a path to any grep-compatible binary on your system; for instance, to avoid using the Apple-provided `grep` on macOS; example:
+
+  ```
+  export GREP=/opt/homebrew/bin/rg
+  ```
+
+* `OTHER_REPO`
+
+  You can use this to specify an `[owner]/[repo]` repo other than the current repo; e.g., a repo the current repo shares part of its commit history with (because the current repo was created from an older repo); example:
+
+  ```
+  export OTHER_REPO=SerenityOS/serenity
+  ```
+
+  If you specify an `OTHER_REPO` value, then if `git-gloss` can’t find any pull request for a particular commit in the current repo, it will then look for a pull request in the repo you specified in the `OTHER_REPO` value.
+
+Rather than exporting each of those environment variables to your shell, you can instead specify them all at the same time in the invocation you use for running `git-gloss` — like this:
+
+```
+OTHER_REPO=SerenityOS/serenity GREP=rg GIT=/opt/homebrew/bin/git ./git-gloss
+```
