--- title: Help Center description: Set up a public-facing help center portal with custom domain and SSL certificate sidebarTitle: Help Center --- Help center allows you to create a portal and add articles from the chatwoot app dashboard. You can point to these help center portal articles from your main site and display them as your public-facing help center. ## How to get SSL certificate for your custom domain ### Create a Portal in Chatwoot's dashboard Follow these step to create your Portal. Refer to [this guide.](https://www.chatwoot.com/hc/user-guide/articles/1677861202-how-to-setup-a-help-center) ### Point your custom domain to your Chatwoot domain 1. Go to your DNS provider and add a new CNAME record. - For the above example, add docs as a CNAME record and point it to the your selfhosted chatwoot domain(FRONTEND_URL). 2. This will ensure that your CNAME record points to the selfhosted Chatwoot installation. For your custom domain, we have your portal information. In this case, `docs.example.com` ### Setting up SSL 1. Use certbot to generate SSL certificates for your custom domain. ```bash certbot certonly --agree-tos --nginx -d "docs.example.com" ``` 2. Create a new nginx config to route requests to this domain to Chatwoot. Make a copy of `/etc/nginx/sites-available/nginx_chatwoot.conf` and make necessary changes for the new domain. 3. Restart nginx server. ```bash sudo systemctl restart nginx ``` Voila! `docs.yourdomain.com` is live with a secure connection, and your portal data is visible. ### How does this work? These are the engineering details to understand `How does docs.yourdomain.com` gets the portal data with SSL certificate. 1. `docs.yourdomain.com` resolves by customers nameserver and redirects to your Chatwoot domain. 2. Chatwoot check for the portal record with custom-domain `docs.yourdomain.com` 3. Redirects to the portal records for the domain `docs.yourdomain.com` Yaay!! Now you can have your own help-center, product-documentation related portal saved at Chatwoot dashboard and served at your domain with SSL certificate.
