  * @param config LinkedHashMap
  *        config includes next parameters:
- *          - credentialsId, id of user which should make checkout
+ *          - credentialsId, id of user which should make checkout(Jenkins Credential)
  *          - branch, branch of project
- *          - host, gerrit-ci hostname
+ *          - host, gerrit-ci hostname(Also, could be in format username@host)
  *          - project, name of project
  *          - targetDir, target directory of cloned repo
  *          - withMerge, prevent detached mode in repo
  *          - withWipeOut, wipe repository and force clone
+ *          - protocol, protocol for git connection(http\https\ssh\file\etc)
+ *          - refspec, A refspec controls the remote refs to be retrieved and how they map to local refs.
+ *          If left blank, it will default to the normal behaviour of git fetch, which retrieves all the branch heads
+ *          as remotes/REPOSITORYNAME/BRANCHNAME. This default behaviour is OK for most cases.
  *
  * Usage example:
  *
  * def gitFunc = new com.mirantis.mcp.Git()
  * gitFunc.gitSSHCheckout ([
- *   credentialsId : 'mcp-ci-gerrit'
- *   branch : 'mcp-0.1'
- *   host : 'ci.mcp-ci.local'
- *   project : 'project'
+ *   credentialsId : 'mcp-ci-gerrit',
+ *   branch : 'mcp-0.1',
+ *   host : 'user@ci.mcp-ci.local',
+ *   project : 'project',
  * ])
+ *
+ * Example for Anon http:
+ * def gitFunc = new com.mirantis.mcp.Git()
+ * gitFunc.gitHTTPCheckout ([
+ *   branch : 'master',
+ *   host : 'ci.mcp-ci.local',
+ *   project : 'project',
+ * ])
