 # actions-test
-Different ways to create a custom action.
+Example of a custom github action
 
-Here you can find examples of how to create very simple github action, with different approaches available.
+## Usage example
+```yml
+    container: prohfesor/actions_test
+    steps:
 
-This simple action prints out `hello world` (or `!FNAME!`, as set).
-Then it takes a directory listing, from the path specified in input vars.
-Output vars contain a timestamp, a random number and a result of directory listing.
+      - name: Hello world action step
