 cases, _Netdata always prioritizes the Go version_, and we highly recommend you use the Go versions for the best
 experience.

 ## Third-party collectors
 
 These collectors are developed and maintained by third parties and, unlike the other collectors, are not installed by
 default. To use a third-party collector, visit their GitHub/documentation page and follow their installation procedures.
 
+<details>
+<summary>Typical third party Python collector installation instructions</summary>
+
+In general the below steps should be sufficient to use a third party collector.
+
+1. Download collector code file
+   into [folder expected by Netdata](https://github.com/netdata/netdata/blob/master/collectors/plugins.d/README.md#environment-variables).
+2. Download default collector configuration file
+   into [folder expected by Netdata](https://github.com/netdata/netdata/blob/master/collectors/plugins.d/README.md#environment-variables).
+3. [Edit configuration file](https://github.com/netdata/netdata/blob/master/docs/collect/enable-configure#configure-a-collector)
+   from step 2 if required.
+4. [Enable collector](https://github.com/netdata/netdata/blob/master/docs/collect/enable-configure#enable-a-collector-or-its-orchestrator).
+5. [Restart Netdata](https://github.com/netdata/netdata/blob/master/docs/configure/start-stop-restart.md)
+
+For example below are the steps to enable
+the [Python ClickHouse collector](https://github.com/netdata/community/tree/main/collectors/python.d.plugin/clickhouse).
+
+```bash
+# download python collector script to /usr/libexec/netdata/python.d/
+$ sudo wget https://raw.githubusercontent.com/netdata/community/main/collectors/python.d.plugin/clickhouse/clickhouse.chart.py -O /usr/libexec/netdata/python.d/clickhouse.chart.py

+$ sudo wget https://raw.githubusercontent.com/netdata/community/main/collectors/python.d.plugin/clickhouse/clickhouse.conf -O /etc/netdata/python.d/clickhouse.conf
+
+# enable collector by adding line a new line with "clickhouse: yes" to /etc/netdata/python.d.conf file
+# this will append to the file if it already exists or create it if not
+$ sudo echo "clickhouse: yes" >> /etc/netdata/python.d.conf

+# (optional) edit clickhouse.conf if needed
+$ sudo vi /etc/netdata/python.d/clickhouse.conf
