 ## Create standalone with SSL enabled
-
 To enable SSL over SplunkWeb, you'll first need to generate your self-signed certificates. Please see the [Splunk docs](https://docs.splunk.com/Documentation/Splunk/latest/Security/Self-signcertificatesforSplunkWeb) on how to go about doing this. For the purposes of local development, you can use:
 ```
 openssl req -x509 -newkey rsa:4096 -passout pass:abcd1234 -keyout /home/key.pem -out /home/cert.pem -days 365 -subj /CN=localhost

+## Create Standalone with Free license
+[Splunk Free](https://docs.splunk.com/Documentation/Splunk/latest/Admin/MoreaboutSplunkFree) is the totally free version of Splunk software. The Free license lets you index up to 500 MB per day and will never expire.
+
+Execute the following to bring up a Splunk Free standalone environment:
+```
+$ docker run --name so1 --hostname so1 -p 8000:8000 -e SPLUNK_PASSWORD=<password> -e SPLUNK_START_ARGS=--accept-license -e SPLUNK_LICENSE_URI=Free -it splunk/splunk:latest
+```
+
 ## Create standalone and universal forwarder
 You can also enable distributed deployments. In this case, we can create a Splunk universal forwarder running in a container to stream logs to a Splunk standalone, also running in a container.

+## Splunk Free license
+Not to be confused with an actual free Splunk enterprise license, but [Splunk Free](https://docs.splunk.com/Documentation/Splunk/latest/Admin/MoreaboutSplunkFree) is a product offering that enables the power of Splunk with a never-expiring but ingest-limited license. By default, when you create a Splunk environment using this Docker container, it will enable a Splunk Trial license which is good for 30 days from the start of your instance. With Splunk Free, you can create a full developer environment of Splunk for any personal, sustained usage. 
+
+To bring up a single instance using Splunk Free, you can run the following command:
+```
+$ docker run --name so1 --hostname so1 -p 8000:8000 -e SPLUNK_PASSWORD=<password> -e SPLUNK_START_ARGS=--accept-license -e SPLUNK_LICENSE_URI=Free -it splunk/splunk:latest
+```
+
 ## Using a license master
 When starting up a distributed Splunk deployment, it may be inefficient for each Splunk instance to apply/fetch the same license. Luckily, there is a dedicated Splunk role for this - `splunk_license_master`. For more information on what this role is, please refer to Splunk documentation on [license masters](https://docs.splunk.com/Documentation/Splunk/latest/Admin/Configurealicensemaster).
