+#### One-off shell wrapper using `pixi exec`
+
+With `pixi exec`, you can also run a one-off command inside a temporary pixi environment.
+
+```yml
+- run: | # everything here will be run inside of the temporary pixi environment
+    zstd --version
+  shell: pixi exec --spec zstd -- bash -e {0}

+```
+
+See [here](https://pixi.sh/latest/reference/cli#exec) for more information about `pixi exec`.
+
+### Environment activation
+
+Instead of using a custom shell wrapper, you can also make all pixi-installed binaries available to subsequent steps by "activating" the installed environment in the currently running job.
+To this end, `setup-pixi` adds all environment variables set when executing `pixi run` to `$GITHUB_ENV` and, similarly, adds all path modifications to `$GITHUB_PATH`.
+As a result, all installed binaries can be accessed without having to call `pixi run`.
+
+```yml
+- uses: prefix-dev/setup-pixi@v0.8.2
+  with:
+    activate-environment: true
+```
+
+If you are installing multiple environments, you will need to specify the name of the environment that you want to be activated.
+
+```yml
+- uses: prefix-dev/setup-pixi@v0.8.2
+  with:
+    environments: >-
+      py311
+      py312
+    activate-environment: py311
+```
+
+Activating an environment may be more useful than using a custom shell wrapper as it allows non-shell based steps to access binaries on the path.
+However, be aware that this option augments the environment of your job.
+
 ### `--frozen` and `--locked`
 
 You can specify whether `setup-pixi` should run `pixi install --frozen` or `pixi install --locked` depending on the `frozen` or the `locked` input argument.
