-## Custom TLS certificates with host mode
-
-### Linux
-
-On linux the custom certificate should be added to your `ca-certificates` bundle.
-For example on Debian based systems (as root):
-
-```bash
-# cp <your custom certificate.crt> /usr/local/share/ca-certificates
-
-# update-ca-certificates
-
-```
-
-Then run LocalStack with the environment variables `REQUESTS_CA_BUNDLE`, `CURL_CA_BUNDLE`, and `NODE_EXTRA_CA_CERTS``:
-
-```bash
-NODE_EXTRA_CA_CERTS=/etc/ssl/certs/ca-certificates.crt \
-  CURL_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt \
-  REQUESTS_CA_BUNDLE=/etc/ssl/certs/ca-certificates.crt \
-  localstack start --host
-```
-
-### macOS
-
-On macOS the custom certificate should be added to your keychain.
-See [this Apple support article](https://support.apple.com/en-gb/guide/keychain-access/kyca2431/mac) for more information.
