 **STEP 2**: Create the certificate signing request (CSR)
 
 ```bash
-openssl req -new -key onlyoffice.key -out onlyoffice.csr

 **STEP 3**: Sign the certificate using the private key and CSR

-Out of the four files generated above, you need to install the `onlyoffice.key`, `onlyoffice.crt` and `dhparam.pem` files at the onlyoffice server. The CSR file is not needed, but do make sure you safely backup the file (in case you ever need it again).
+Out of the four files generated above, you need to install the `tls.key`, `tls.crt` and `dhparam.pem` files at the onlyoffice server. The CSR file is not needed, but do make sure you safely backup the file (in case you ever need it again).
 
 The default path that the onlyoffice application is configured to look for the SSL certificates is at `/var/www/onlyoffice/Data/certs`, this can however be changed using the `SSL_KEY_PATH`, `SSL_CERTIFICATE_PATH` and `SSL_DHPARAM_PATH` configuration options.
 
-The `/var/www/onlyoffice/Data/` path is the path of the data store, which means that you have to create a folder named certs inside `/app/onlyoffice/DocumentServer/data/` and copy the files into it and as a measure of security you will update the permission on the `onlyoffice.key` file to only be readable by the owner.
