+# Ansible-Role "ansible_lza_bootstrap_rhel_server"
+
+## Description
+
+This role provides all necessary tasks to initialise RHEL 7 servers for SLUBArchiv before a non-root user takes over for further managemant.
+
+## Prerequisites
+
+To use this role, the following software must be installed on your workstation:
+* ansible
+
+To deploy this role to a managed host, the following software must be installed on the target:
+* Python3
+* SSHd
+
+## General usage
+
+Most options already have sensible defaults in `ansible.cfg`. However, you can override these defaults using CLI options/flags if you want to.
+
+To simply run the playbook, just call the `site.yml` playbook like this:
+```
+	ansible-playbook site.yml -u <username>
+```
+
+If you want to limit the execution to a subset of all hosts that are listed in the inventory, use the `-l` or `--limit` option like this:
+```
+	ansible-playbook site.yml -l <hostna*>
+	ansible-playbook site.yml -l <hostname>
+	ansible-playbook site.yml -l <hostname1>:<hostname2>:...
+	ansible-playbook site.yml -l <inventory_group>
+	ansible-playbook site.yml --limit=<hostna*>
+```
+
+If you do not have Vault password files in the directory above the role direcory, you have to give the Vault password before execution:
+```
+	ansible-playbook site.yml --ask-vault-pass
+```
+
+You can use your own inventory file by adding the `-i` or `--inventory=INVENTORY` option:
+```
+	ansible-playbook site.yml -i inventory.yml
+	ansible-playbook site.yml --inventory=inventory.yml
+```
+
+Tasks in this role have been tagged to enable users to only run subsets of tasks. This can be leveraged to decrease run times or run only certain tasks after small changes.
+To list all available tags, use:
+```
+	ansible-playbook site.yml --list-tags
+```
+You can then run only certain tagged tasks by using the `--tags` option:
+```
+	ansible-playbook site.yml -t tag1,tag2,...,tagN
+	ansible-playbook site.yml --tags=tag1,tag2,...,tagN
+```
+
+For more help with ansible-playbook, use the `--help` flag.
+
+## Testing the role
+
+Tests have been implemented using the Molecule framework. The details on using the test suite are described below `molecule/`.
+
+## Variables
+
+Many variables have been "hidden" in encrypted Ansible Vaults. However, in order to better understand the data within the vaults, you can find `\*.vault.example` files below the `vars/` directory.
+
+## git configuration
+
+Just run the `setup_gitconfig.sh` script that comes with the repo to correctly setup all necessary local Git configurations.
+
+## Author Information
+
+If you have any comments or find bugs, please contact langzeitarchiv@slub-dresden.de or issue a pull request.
