+#### Confluence Cloud
+
+For those using Confluence Cloud you will need to have the following configuration:
+
+```yaml
+confluence:
+  baseUrl: ${CONFLUENCE_BASE_URL}
+  token: ${CONFLUENCE_TOKEN}
+  isCloud: true
+```
+
+##### baseUrl
+
+The `baseUrl` for Confluence Cloud should include the product name which is `wiki` by default but can be something else if your Org has changed it. An example `baseUrl` for Confluence Cloud would look like this: `https://example.atlassian.net/wiki`
+
+##### token
+
+The `token` for Confluence Cloud needs to be base-64 encoded with your Atlassian account email address. Here's how to do that:
+
+1. First get your token from: `https://<company-name>.atlassian.com/manage-profile/security/api-tokens`
+2. Next we need to setup a string in this format: `<your-atlassian-account-mail>:<your-jira-token>`
+3. For this example we'll use this: `confluence@backstage.io:wDzAzoXWRGLtvbgHvT0W`
+4. Now we can run `echo -n "confluence@backstage.io:wDzAzoXWRGLtvbgHvT0W" | base64`
+5. This gives us: `Y29uZmx1ZW5jZUBiYWNrc3RhZ2UuaW86d0R6QXpvWFdSR0x0dmJnSHZUMFc=` which we can now use as the value for the `token` in the configuration
