-# Zabbix Template Exporter
+# Zabbix Configuration Exporter
+
+This tool connects to the Zabbix API and retrieves configuration and stores this in individual files, allowing you to re-use these templates and make backups of them (e.g. by adding them to version control).
+
+It is capable of exporting the following:
+
+* Templates
+* Mediatypes
+* Hosts
+* Host Groups
+* Maps
+* Images
+
+Tested with Zabbix 5.4.x
+
 
-This tool connects to the Zabbix API.
-It retrieves all templates and stores them in individual XML files allowing you to re-use these templates and make backups of them.
 
 ## Install
 Install the requirements:
+
 ```bash
 $ pip3 install -r requirements.txt
 ```
 
 ## Usage
 You can provide your credentials on the commandline:
+
 ```bash
-usage: export.py [-h] [--server ZABBIX_HOST] [--username ZABBIX_USER]
-                 [--password ZABBIX_PASSWORD] [--format EXPORT_FORMAT]
-                 [--type EXPORT_TYPE] [--debug]
+usage: export.py [-h] [--server ZABBIX_HOST] [--token ZABBIX_API_TOKEN] [--format {xml,json,yaml}] [--type {templates,mediatypes,hosts,hostgroups,maps,images}] [--debug]
 
 optional arguments:
   -h, --help            show this help message and exit
   --server ZABBIX_HOST, -s ZABBIX_HOST
                         Zabbix URL
-  --username ZABBIX_USER, -u ZABBIX_USER
-                        Zabbix user to connect with the API
-  --password ZABBIX_PASSWORD, -p ZABBIX_PASSWORD
-                        Zabbix password for connecting to the API
-  --format EXPORT_FORMAT, -f EXPORT_FORMAT
+  --token ZABBIX_API_TOKEN
+                        Zabbix API token
+  --format {xml,json,yaml}, -f {xml,json,yaml}
                         Export the templates as XML or JSON
-  --type EXPORT_TYPE, -t EXPORT_TYPE
+  --type {templates,mediatypes,hosts,hostgroups,maps,images}, -t {templates,mediatypes,hosts,hostgroups,maps,images}
                         Export this type of entities
   --debug, -d           Enable debugging output
+
+
 ```
 
 You can also configure your credentials globally and export these (e.g. in `.bashrc` or `.zshrc`) like this:
 
 ```bash
 export ZABBIX_HOST=https://zabbix.example.com
-export ZABBIX_USER=youruser
-export ZABBIX_PASS=yourpass
+export ZABBIX_API_TOKEN=your-token
 ```
 
-Both `ZABBIX_USER` and `ZABBIX_PASS` can be provided as a string or a base64 string to prevent the passwords from being visible easily.
-The exporter automatically detects the content and will act accordingly.
+## Limitations
 
+* Exporting auto-discovered hosts results in an empty file, because the Zabbix API does not provide this information.
