 # Frequently Asked Questions
 
-## How to I get the repository ID to put in my Actions secrets for use with the reusable release workflow?
+## How do I get the repository-id and category-id for the release reusable workflow's discussion part
 
-You can get a repository's ID via the GitHub Rest API endpoint](https://docs.github.com/en/rest/repos/repos?apiVersion=2022-11-28#get-a-repository).  I found using the `gh` CLI tool to be the easiest way to get the repository ID.  You can use the following command to get the repository ID:
-
-change the `OWNER` and `REPO` to the repository you are interested in.
-
-```bash
-# GitHub CLI api
-# https://cli.github.com/manual/gh_api
-
-gh api \
-  -H "Accept: application/vnd.github+json" \
-  -H "X-GitHub-Api-Version: 2022-11-28" \
-  /repos/OWNER/REPO
-```
-
-## How do I get the discussion category ID to put in my Actions secrets for use with the reusable release workflow?
-
-You can get a repository's discussion category ID via the GitHub GraphQL API.  You can use the [GraphQL Explorer UI Tool](https://docs.github.com/en/graphql/overview/explorer) to get the discussion category ID.  You can use the following query to get the discussion category ID:
-
-change the `owner` and `name` to the repository you are interested in.
-
-```graphql
-query {
-  repository(owner: "jmeridth", name: "reusable-workflows") {
-    discussionCategories(first: 10) {
-      nodes {
-        # type: DiscussionCategory
-        id
-        name
-      }
-    }
-  }
-}
-```
+The workflow I use to generate the discussion has this information in its [README](https://github.com/abirismyname/create-discussion/tree/6e6ef67e5eeb042343ef8b3d8d0f5d545cbdf024/?tab=readme-ov-file#obtaining-the-repository-id-and-category-id)
