You community needs a content home. The internal wiki will solve for that. Include all the community content, resources, guides, mentor details and also a member directory. If it's a learning community, you can use one of the LMS platforms to host your content.
Here's how you can use this template:
1) Click on the 'Framework Template'. It will take you to the Notion doc.
2) Duplicate it to your workspace by clicking on the 'Duplicate' button on the top right corner (you'll need to create an account on Notion if you don't have one - the free one should do).
3) Make the doc your workbook to get this task done!
