+Contribute to yii2-fractal library
+==================================
+
+### Local setup
+
+[Docker](https://docs.docker.com/engine/install/) is required
+
+```bash
+git clone git@github.com:php-openapi/yii2-fractal.git
+cd yii2-fractal
+make up
+make installdocker # only once during initiation
+```
+
+### Test
+
+Ensure you followed steps mentioned in Local setup, then
+
+```bash
+make cli
+make test
+```
+
+### Switching PHP versions
+
+
+You can switch the PHP version of the docker runtime by changing the `PHP_VERSION` environment variable in the `.env` file.
+
+If you have no `.env` file yet, create it by copying `.env.dist` to `.env`.
+
+After changing the PHP Version you need to run `make clean_all up` to start the new container with new version.
+
+Example:
+
+```
+$ echo "PHP_VERSION=7.4" > .env
+$ make clean_all up cli
+Stopping yii2-openapi_php_1      ... done # TODO
