 # Commander
 
-`Commander` is an alternative to `bats` and `gotest.tools/icmd` for testing cli apps.
+
+Define language independent tests for your command line scripts and programs in simple `yaml` files.
 
  - It runs on `windows`, `osx` and `linux` 
  - It is a self-contained binary - no need to install a heavy lib or language

  - Add the path to your [path](https://docs.alfresco.com/4.2/tasks/fot-addpath.html) environment variable
  - Test it: `commander --version`
 
-## Example
 
-You can find more examples in `examples/`
+## Quick start

-# Build the project
-$ make build
+`Commander` will always search for a default `commander.yaml` in the current working directory and execute all defined tests in it.

+```bash
+# You can even let commander add tests for you!
+$ ./commander test examples/commander.yaml
+tests:
+  echo hello:
+    exit-code: 0
+    stdout: hello

+    dir: /tmp #Set working directory
+    env: # Environment variables
+        KEY: global
+    timeout: 5000 # Timeout in ms

+            retries: 5
         exit-code: 0
 ```
 
+## Executing
+
+```bash
+# Execute file commander.yaml in current directory
+$ ./commander test 
+
+# Execute a specific suite
+$ ./commander test /tmp/test.yaml
+
+# Execute a single test
+$ ./commander test /tmp/test.yaml "my test"
+```
+
+## Adding tests
+
+You can use the `add` argument if you want to `commander` to create your tests.
+
+```bash
+# Add a test to the default commander.yaml
+$ ./commander add echo hello
+written to /tmp/commander.yaml
+
+# Write to a given file
+$ ./commander add --file=test.yaml echo hello
+written to test.yaml
+
+# Write to stdout and file
+$ ./commander add --stdout echo hello
+tests:
+  echo hello:
+    exit-code: 0
+    stdout: hello
+
+written to /tmp/commander.yaml
+
+# Only to stdout
+$ ./commander add --stdout --no-file echo hello
+tests:
+  echo hello:
+    exit-code: 0
+    stdout: hello
