+The contents of the `.github` folder are not preserved by the transition tool. If you had any custom workflow files in your lesson repository before migrating to the new infrastructure, you will need to add those back into `.github/workflows/` at this point then commit the changes.

 #### Build and check your transitioned lesson
 At this stage, the `release/carpentries-incubator/YOUR-LESSON-NAME/` directory should contain a transitioned version of your lesson. 
 To check how things are looking, [install the Workbench tools for your system](index.html#installation), then open R in this directory and run `sandpaper::serve()`.

 While previewing this transitioned lesson site, you might see some problems in the content of your lesson site that appeared during the migration. Liquid comments (delineated by `{% comment %}` and `{% endcomment %}` tags) are one commonly-encountered artifact. Another is broken links to the lesson setup instructions, which are found at `index.html#setup` in a Workbench site. These can be fixed by editing the lesson after transition, but for a cleaner commit history on your lesson you might wish to delete the transitioned lesson directory (inside the `release` folder), modify the R script for your lesson to handle those issues, and re-run the transition tool. (See [_Create an Rscript for your lesson_](#Rscript) above.)
 
 #### If something goes wrong
-
 To go back to the start and try again, delete the directory for your lesson within the `release/` directory, i.e. `rm -rf release/carpentries-incubator/YOUR-LESSON-NAME`.
 
 If the transition tool ran successfully but your lesson build fails, this is usually due to customisations made to the lesson that fall outside what the transition tool expected to find.
