 # Actions
 
 Reusable steps and workflows for GitHub Actions, focused on Python packages.
+
+## Script with post step
+
+JavaScript Actions support defining `pre`, `pre-if`, `post` and `post-if` steps, which allow executing steps at the
+beginning or the end of a job, regardless of intermediate steps failing.
+Unfortunately, those are not available for any other Action type.
+
+Action [with-post-step](with-post-step) is a generic JS Action to execute a main command and to set a command as a post
+step.
+It allows using the `post` feature with scripts written in bash, python or any other interpreted language available on
+the environment.
+See: [actions/runner#1478](https://github.com/actions/runner/issues/1478).
