 There are also some other options to start Trilium:
 
 * `trilium-no-cert-check` - Trilium will not validate the certificates, useful e.g. when you're syncing against a sync server with self-signed certificate
+  * Alternatively you can set `NODE_TLS_REJECT_UNAUTHORIZED=0` environment variable to the Trilium process.
 * `trilium-portable` - Trilium will try to create [[data directory]] in the trilium's directory
 * `trilium-safe-mode` - start up in "safe mode" which disables any startup scripts which might e.g. crash the application

 Above is only example of how this is set up on my environment when I generated the certificate using Let's encrypt acme utility. Your paths may be completely different. (Note that if you are using a Docker installation, these paths should be in a volume or other path understood by the docker container, e.g., /home/node/trilium-data/[DIR IN DATA DIRECTORY].)

+## Self-signed certificate
+
+If you need to use a self-signed certificate for your server instance, the desktop instance won't trust it.
+
+Currently the only way to make this work is by disabling certificate validation by setting this environment variable (for Linux):
+
+```
+export NODE_TLS_REJECT_UNAUTHORIZED=0
+trilium
+```
+
+Trilium comes with scripts to start Trilium in this mode, e.g. `trilium-no-cert-check.bat` for Windows.
+
+** Note that disabling TLS certificate validation is insecure, so do it only if you're sure you know what you're doing! **
