## Summary
Adds comprehensive documentation for the `IS_MULTIWORKSPACE_ENABLED`
configuration variable, which was previously undocumented despite being
a fundamental configuration option that significantly changes how Twenty
behaves.
## Changes
### Self-Host Setup Guide (`setup.mdx`)
Added a new **Multi-Workspace Mode** section that explains:
- **Single-workspace mode (default)**: Only one workspace allowed, first
user gets admin privileges, signups disabled after first workspace
- **Multi-workspace mode**: Multiple workspaces with subdomain-based
URLs (e.g., `sales.your-domain.com`)
- **Related config variables**: `DEFAULT_SUBDOMAIN` and
`IS_WORKSPACE_CREATION_LIMITED_TO_SERVER_ADMINS`
- **DNS configuration**: Wildcard DNS setup for dynamic subdomains
- **Workspace creation restrictions**: How to limit workspace creation
to server admins
### Local Setup Guide (`local-setup.mdx`)
Added an info callout in the environment variables section to make
contributors aware of multi-workspace mode, useful when testing
subdomain-based features.
## Why This Matters
The `IS_MULTIWORKSPACE_ENABLED` variable controls:
- Whether multiple workspaces can exist on a single instance
- URL structure (plain domain vs subdomains)
- First user privileges
- Sign-up behavior after initial setup
- SSO workspace resolution logic
This is critical knowledge for self-hosters who want to run Twenty as a
multi-tenant SaaS.
Reorganizing by Feature sections
Capabilities folders to give an overview of each feature
How-Tos folders to give guidance for advanced customizations
Reorganized the Developers section as well, moving the API sub section
there
added some new visuals and videos to illustrate the How-Tos articles
checked the typos, the links and added a section at the end of the
doc.json file to redirect existing links to the new ones (SEO purpose +
continuity of the user experience)
What I have not updated is the "l" folder that, per my understanding,
contains the translation of the User Guide - that I only edited in
English
