 ## Application Setup
 
-> ### Migrating from the old `linuxserver/letsencrypt` image
-> * If using docker cli:
->   * Stop and remove existing container via `docker stop letsencrypt` and `docker rm letsencrypt`
->   * Create new container using the sample on this page (container name: `swag`, image name: `linuxserver/swag`)
-> * If using docker compose:
->   * Edit the compose yaml to change the image to `linuxserver/swag` and change the service and container names to `swag`
->   * Issue `docker-compose up -d --remove-orphans`
->   * If you don't want to or can't use the option `--remove-orphans`, then you can first do `docker-compose down`, then edit the compose yaml as above, and then issue `docker-compose up -d`
-
-> Make sure to also update any references to this container by name. For instance, Nextcloud's `config.php` references this container in its `trusted_proxies` directive, which would have to be updated to `swag`.
 ### Validation and initial setup
+
 * Before running this container, make sure that the url and subdomains are properly forwarded to this container's host, and that port 443 (and/or 80) is not being used by another service on the host (NAS gui, another webserver, etc.).
 * For `http` validation, port 80 on the internet side of the router should be forwarded to this container's port 80
 * For `dns` validation, make sure to enter your credentials into the corresponding ini (or json for some plugins) file under `/config/dns-conf`
@@ -79,20 +70,26 @@ The architectures supported by this image are:
 * If you need a dynamic dns provider, you can use the free provider duckdns.org where the `URL` will be `yoursubdomain.duckdns.org` and the `SUBDOMAINS` can be `www,ftp,cloud` with http validation, or `wildcard` with dns validation.
 * After setup, navigate to `https://yourdomain.url` to access the default homepage (http access through port 80 is disabled by default, you can enable it by editing the default site config at `/config/nginx/site-confs/default`).
 * Certs are checked nightly and if expiration is within 30 days, renewal is attempted. If your cert is about to expire in less than 30 days, check the logs under `/config/log/letsencrypt` to see why the renewals have been failing. It is recommended to input your e-mail in docker parameters so you receive expiration notices from Let's Encrypt in those circumstances.
+
 ### Security and password protection
+
 * The container detects changes to url and subdomains, revokes existing certs and generates new ones during start.
 * Per [RFC7919](https://datatracker.ietf.org/doc/html/rfc7919), the container is shipping [ffdhe4096](https://ssl-config.mozilla.org/ffdhe4096.txt) as the `dhparams.pem`.
 * If you'd like to password protect your sites, you can use htpasswd. Run the following command on your host to generate the htpasswd file `docker exec -it swag htpasswd -c /config/nginx/.htpasswd <username>`
 * You can add multiple user:pass to `.htpasswd`. For the first user, use the above command, for others, use the above command without the `-c` flag, as it will force deletion of the existing `.htpasswd` and creation of a new one
 * You can also use ldap auth for security and access control. A sample, user configurable ldap.conf is provided, and it requires the separate image [linuxserver/ldap-auth](https://hub.docker.com/r/linuxserver/ldap-auth/) to communicate with an ldap server.
+
 ### Site config and reverse proxy
+
 * The default site config resides at `/config/nginx/site-confs/default`. Feel free to modify this file, and you can add other conf files to this directory. However, if you delete the `default` file, a new default will be created on container start.
 * Preset reverse proxy config files are added for popular apps. See the `README.md` file under `/config/nginx/proxy_confs` for instructions on how to enable them. The preset confs reside in and get imported from [this repo](https://github.com/linuxserver/reverse-proxy-confs).
 * If you wish to hide your site from search engine crawlers, you may find it useful to add this configuration line to your site config, within the server block, above the line where ssl.conf is included
 `add_header X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";`
 This will *ask* Google et al not to index and list your site. Be careful with this, as you will eventually be de-listed if you leave this line in on a site you wish to be present on search engines
 * If you wish to redirect http to https, you must expose port 80
+
 ### Using certs in other containers
+
 * This container includes auto-generated pfx and private-fullchain-bundle pem certs that are needed by other apps like Emby and Znc.
   * To use these certs in other containers, do either of the following:
   1. *(Easier)* Mount the container's config folder in other containers (ie. `-v /path-to-le-config:/le-ssl`) and in the other containers, use the cert location `/le-ssl/keys/letsencrypt/`

   * Preset reverse proxy config files are added for popular apps. See the `README.md` file under `/config/nginx/proxy_confs` for instructions on how to enable them. The preset confs reside in and get imported from [this repo](https://github.com/linuxserver/reverse-proxy-confs).
   * If you wish to hide your site from search engine crawlers, you may find it useful to add this configuration line to your site config, within the server block, above the line where ssl.conf is included
   `add_header X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";`
   This will *ask* Google et al not to index and list your site. Be careful with this, as you will eventually be de-listed if you leave this line in on a site you wish to be present on search engines
   * If you wish to redirect http to https, you must expose port 80
