+# jj - Jujutsu CLI
+
+This plugin provides autocompletion for [jj](https://martinvonz.github.io/jj).
+
+To use it, add `jj` to the plugins array of your zshrc file:
+
+```zsh
+plugins=(... jj)
+```
+
+## Aliases
+
+| Alias  | Command                       |
+| ------ | ----------------------------- |
+| jjc    | `jj commit`                   |
+| jjcmsg | `jj commit --message`         |
+| jjd    | `jj diff`                     |
+| jjdmsg | `jj desc --message`           |
+| jjds   | `jj desc`                     |
+| jje    | `jj edit`                     |
+| jjgcl  | `jj git clone`                |
+| jjgf   | `jj git fetch`                |
+| jjgp   | `jj git push`                 |
+| jjl    | `jj log`                      |
+| jjla   | `jj log -r "all()"`           |
+| jjn    | `jj new`                      |
+| jjrb   | `jj rebase`                   |
+| jjrs   | `jj restore`                  |
+| jjrt   | `cd "$(jj root \|\| echo .)"` |
+| jjsp   | `jj split`                    |
+| jjsq   | `jj squash`                   |
+
+## Prompt usage
+
+Because `jj` has a very powerful [template syntax](https://martinvonz.github.io/jj/latest/templates/), this
+plugin only exposes a convenience function `jj_prompt_template` to read information from the current change.
+It is basically the same as `jj log --no-graph -r @ -T $1`:
+
+```sh
+_my_theme_jj_info() {
+  jj_prompt_template 'self.change_id().shortest(3)'
+}
+
+PROMPT='$(_my_theme_jj_info) $'
+```
+
+`jj_prompt_template` escapes `%` signs in the output. Use `jj_prompt_template_raw` if you don't want that
+(e.g. to colorize the output).
+
+However, because `jj` can be used inside a Git repository, some themes might clash with it. Generally, you can
+fix it with a wrapper function that tries `jj` first and then falls back to `git` if it didn't work:
+
+```sh
+_my_theme_vcs_info() {
+  jj_prompt_template 'self.change_id().shortest(3)' \
+  || git_prompt_info
+}
+
+PROMPT='$(_my_theme_vcs_info) $'
+```
+
+You can find an example
+[here](https://github.com/nasso/omzsh/blob/e439e494f22f4fd4ef1b6cb64626255f4b341c1b/themes/sunakayu.zsh-theme).
+
+### Performance
+
+Sometimes `jj` can be slower than `git`.
+
+If you feel slowdowns, consider using the following:
+
+```
+zstyle :omz:plugins:jj ignore-working-copy yes
+```
+
+This will add `--ignore-working-copy` to all `jj` commands executed by your prompt. The downside here is that
+your prompt might be out-of-sync until the next time `jj` gets a chance to _not_ ignore the working copy (i.e.
+you manually run a `jj` command).
+
+If you prefer to keep your prompt always up-to-date but still don't want to _feel_ the slowdown, you can make
+your prompt asynchronous. This plugin doesn't do this automatically so you'd have to hack your theme a bit for
+that.
