+## Helper Scripts
+
+> [!NOTE]
+> If you are working with the step-based challenges, refer to the [Work on Practice Projects](how-to-work-on-practice-projects.md) section.
+
+There are a few helper scripts that can be used to manage the challenges in a block. Note that these commands should all be run in the block directory. For example:
+
+```bash
+cd curriculum/challenges/english/02-javascript-algorithms-and-data-structures/basic-algorithm-scripting
+```
+
+### Add New Challenge
+
+To add a new challenge at the end of a block, call the script:
+
+```bash
+pnpm run create-next-challenge
+```
+
+This will prompt you for the challenge information and create the challenge file, updating the `meta.json` file with the new challenge information.
+
+### Delete a Challenge
+
+To delete a challenge, call the script:
+
+```bash
+pnpm run delete-challenge
+```
+
+This will prompt you to select which challenge should be deleted, then delete the file and update the `meta.json` file to remove the challenge from the order.
+
+### Insert a Challenge
+
+To insert a challenge before an existing challenge, call the script:
+
+```bash
+pnpm run insert-challenge
+```
+
+This will prompt you for the challenge information, then for the challenge to insert before. For example, if your choices are:
+
+```bash
+a
+b
+c
+```
+
+And you choose `b`, your new order will be:
+
+```bash
+a
+new challenge
+b
+c
+```
+
+### Update Challenge Order
+
+If you need to manually re-order the challenges, call the script:
+
+```bash
+pnpm run update-challenge-order
+```
+
+This will take you through an interactive process to select the order of the challenges.
