 - `checkstyle.additional.suppressions.file` - this variable corresponds to suppressions in your local project. E.g. you're working on `spring-cloud-contract`. Then point to the `project-root/src/checkstyle/checkstyle-suppressions.xml` folder. Example for `spring-cloud-contract` would be: `/home/username/spring-cloud-contract/src/checkstyle/checkstyle-suppressions.xml`.
 
 IMPORTANT: Remember to set the `Scan Scope` to `All sources` since we apply checkstyle rules for production and test sources.

 - `checkstyle.additional.suppressions.file` - this variable corresponds to suppressions in your local project. E.g. you're working on `spring-cloud-contract`. Then point to the `project-root/src/checkstyle/checkstyle-suppressions.xml` folder. Example for `spring-cloud-contract` would be: `/home/username/spring-cloud-contract/src/checkstyle/checkstyle-suppressions.xml`.
 
 IMPORTANT: Remember to set the `Scan Scope` to `All sources` since we apply checkstyle rules for production and test sources.

-The idea of this script is to update gh-pages branch with the generated docs. Without any options
-the script will work in the following manner:
-
-- if there's no gh-pages / target for docs module then the script ends
-- for master branch the generated docs are copied to the root of gh-pages branch
-- for any other branch (if that branch is allowed) a subfolder with branch name is created
-    and docs are copied there
-- if the version switch is passed (-v) then a tag with (v) prefix will be retrieved and a folder
-    with that version number will be created in the gh-pages branch. WARNING! No allow verification will take place
-- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
-    switch to gh-pages of that repo and copy the generated docs to [docs/<project-name>/<version>]
-- if the destination switch is passed (-d) then the script will check if the provided dir is a git repo and then will
-    switch to gh-pages of that repo and copy the generated docs to [docs/<project-name>/<version>]
-- if the release train switch is passed (-r) then the script will check if the provided dir is a git repo and then will
-    switch to gh-pages of that repo and copy the generated docs to [docs/<version>]
-
-USAGE:
-
-You can use the following options:
-
--v|--version        - the script will apply the whole procedure for a particular library version
--r|--releasetrain   - instead of nesting the docs under the project_name/version folder the docs will end up in version
--d|--destination    - the root of destination folder where the docs should be copied. You have to use the full path.
-                        E.g. point to spring-cloud-static folder. Can't be used with (-c)
--b|--build          - will run the standard build process after checking out the branch
--c|--clone          - will automatically clone the spring-cloud-static repo instead of providing the destination.
-                        Obviously can't be used with (-d)
