+# Stacklight tests
+
+
+This project based on two other projects:
+
+  * Devops: [Devops documentation](http://docs.fuel-infra.org/fuel-dev/devops.html)
+
+  * Fuel-QA: [Fuel-QA documentation](https://docs.fuel-infra.org/fuel-qa/)
+
+
+## Step-by-step guide:
+
+
+1. Prepare the environment:
+
+  * `vi openrc`
+
+  * `. openrc`
+
+  * `./utils/fuel-qa-builder/prepare_env.sh`
+
+
+2. Run the tests:
+
+  `./utils/jenkins/system_tests.sh -k -K -j fuelweb_test -t test -w $(pwd) -o --group=<your_test_group_to_run>`
+
+  You can read more about on https://docs.fuel-infra.org/fuel-qa/ or
+  run it next way to view help: `./utils/jenkins/system_tests.sh -h`.
+
+
+
+## To contributors:
+
+Please, follow next rules:
+
+* run `tox` or `tox -epep8` before send to review
+
+* try to reuse in dependencies previous deployed environment in
+`@test(depends_on=[<dependency>]`
+(usually basic env is deployed in smoke bvt tests)
+
+* mark test group following next pattern:
+
+ ```
+ @test(groups=["<full_unique_name_of_test>",
+               "<test_method_purpose>",
+               "<plugin_name>",
+               "<test_category>"])
+ ```
+
+ For example:
+
+ ```
+ @test(groups=["install_influxdb_grafana",
+               "install",
+               "influxdb_grafana",
+               "smoke"])
+ ```
