Update README

Reformat beginning and move badges before the initial header like in the
 ansible-lint project.
Remove outdated ansible-lint call with --parseable-severity, because it
 was removed in ansible/ansible-lint#1898.
Reformat list of available calls to make look like there are several
 methods of calling ansible-lint-junit, not a list of consecutive
 actions.
Add information about project license.
Fix grammar and style.

+Ansible-lint-junit
 ---
 
+The [ansible-lint](https://github.com/willthames/ansible-lint) to JUnit converter.
+
 ### Installation
-via pip;
+
+via pip:
+
 ```shell
 pip install ansible-lint-junit
 ```
 
 ### Updating
+
 via pip:
+
 ```shell
 pip install ansible-lint-junit --upgrade
 ```
 
 ### Usage:
-1. you can pipe output of `ansible-lint`:
-    ```shell
-    # less verbose
-    ansible-lint playbook.yml -p --nocolor | ansible-lint-junit -o ansible-lint.xml
-
-    # more verbose
-    ansible-lint playbook.yml --parseable-severity --nocolor | ansible-lint-junit -o ansible-lint.xml
-    ```
-3. or run `ansible-lint` on your playbook(s) and redirect output to file
-    ```shell
-    # less verbose
-    ansible-lint -p --nocolor your_fancy_playbook.yml > ansible-lint.txt
-
-    # more verbose
-    ansible-lint --parseable-severity --nocolor your_fancy_playbook.yml > ansible-lint.txt
-    ```
-    and run `ansible-lint-junit` and pass generated file to it
-    ```shell
-    # less verbose
-    ansible-lint-junit ansible-lint.txt -o ansible-lint.xml
-
-    # more verbose
-    ansible-lint-junit ansible-lint.txt -o ansible-lint.xml
-    ```
+
+- You can run `ansible-lint` on your playbook(s) and redirect output to pipe
+  ```shell
+  ansible-lint playbook.yml -p --nocolor | ansible-lint-junit -o ansible-lint.xml
+  ```
+- You can use a temporary file to store the output of `ansible-lint`.
+  And then run `ansible-lint-junit` and pass generated file to it
+  ```shell
+  ansible-lint -p --nocolor your_fancy_playbook.yml > ansible-lint.txt
+  ansible-lint-junit ansible-lint.txt -o ansible-lint.xml
+  ```
 
 ### Output
-* if there are any lint errors, full JUnit XML will be created
-* if there are no errors, empty JUnit XML will be created, this is for i.e. [Bamboo](https://www.atlassian.com/software/bamboo) JUnit parser plugin compatibility.
-It will break build if XML is missing or incorrect, and there is really no way of generating XML with *"PASSED"* tests in case of linter.
