-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, caste, color, religion, or sexual
-identity and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the overall
-  community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or advances of
-  any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email address,
-  without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement by
-[opening a new issue in this repository's issue tracker][open issue].
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series of
-actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or permanent
-ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior, harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
-
-**Consequence**: A permanent ban from any sort of public interaction within the
-community.

-# NetBox SLM contributing guidelines
-
-## What do I need to know to help?
-
-If you are looking to help to with a code contribution our project uses, you can find inspiration in the [issue list](https://github.com/ICTU/netbox_slm/issues/).
-Additionally, review the [README](./README.md) document and [NetBox Plugin Development](https://docs.netbox.dev/en/stable/plugins/development/) docs.
-
-## How do I make a contribution?
-
-Never made an open source contribution before? Wondering how contributions work in the in our project? Here's a quick rundown!
-
-1. Find an issue that you are interested in addressing or a feature that you would like to add.
-2. Fork the repository associated with the issue to your local GitHub organization. This means that you will have a copy of the repository under **your-GitHub-username/repository-name**.
-3. Clone the repository to your local machine using `git clone https://github.com/github-username/repository-name.git`.
-4. Create a new branch for your fix using `git checkout -b branch-name-here`.
-5. Make the appropriate changes for the issue you are trying to address or the feature that you want to add.
-6. Use git `add insert-paths-of-changed-files-here` to add the file contents of the changed files to the "snapshot" git uses to manage the state of the project, also known as the index.
-7. Use `git commit -m "Insert a short message of the changes made here"` to store the contents of the index with a descriptive message.
-8. Push the changes to the remote repository using `git push origin branch-name-here`.
-9. Submit a pull request to the upstream repository.
-10. Title the pull request with a short description of the changes made and the issue or bug number associated with your change. For example, you can title an issue like so "Added more log outputting to resolve #4352".
-11. In the description of the pull request, explain the changes that you made, any issues you think exist with the pull request you made, and any questions you have for the maintainer. It's OK if your pull request is not perfect (no pull request is), the reviewer will be able to help you fix any problems and improve it!
-12. Wait for the pull request to be reviewed by a maintainer.
-13. Make changes to the pull request if the reviewing maintainer recommends them.
-14. Celebrate your success after your pull request is merged!
-
-## Where can I go for help?
-
-If you need help, you can ask questions by [opening a new issue in this repository's issue tracker](https://github.com/ICTU/netbox_slm/issues/new).
-
-## What does the Code of Conduct mean for me?
-
-Our [Code of Conduct](./CODE_OF_CONDUCT.md) means that you are responsible for treating everyone on the project with respect and courtesy regardless of their identity.
-If you are the victim of any inappropriate behavior or comments as described in our Code of Conduct, we are here for you and will do the best to ensure that the abuser is reprimanded appropriately, per our code.

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:

+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+Diese Variante ist für **NetBox 4.6.5** vorgesehen.

+Die Oberfläche ist auf Englisch und Deutsch verfügbar. Die Sprache richtet sich nach der in NetBox für den
+Benutzer ausgewählten Sprache.

-## Known Issues

-## Installation Guide
+> **Hinweis:** Lizenzschlüssel werden in der NetBox-Datenbank und Lizenzdateien im konfigurierten NetBox-
+> Medienverzeichnis gespeichert. Der Zugriff auf Datenbank, REST-API und Medienverzeichnis sollte entsprechend
+> geschützt und gesichert werden.

-When using the Docker version of NetBox, first follow the netbox-docker [quickstart](https://github.com/netbox-community/netbox-docker#quickstart) instructions to clone the netbox-docker repo and set up the ``docker-compose.override.yml``.
+## Installation

-Next, follow these instructions (based on the NetBox docker variant
-[instructions](https://github.com/netbox-community/netbox-docker/wiki/Configuration#custom-configuration-files))
-to install the NetBox SLM plugin:
+NetBox installiert lokale Erweiterungen aus `/opt/netbox/local_requirements.txt`. Die Git-URL muss dort dauerhaft
+eingetragen werden, damit das Plugin bei einem späteren NetBox-Upgrade erneut installiert wird.

-1. Add ``netbox_slm`` to the ``PLUGINS`` list in
-   ``configuration/plugins.py``.
-2. Create a ``plugin_requirements.txt`` with ``netbox-slm`` as
-   contents.
-3. Create a ``Dockerfile-SLM`` with contents:
+### 1. Git-Repository als lokale Anforderung eintragen

-   ```
-   FROM netboxcommunity/netbox:vX.Y.Z
+```bash
+echo "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git" >> /opt/netbox/local_requirements.txt
+```

-   COPY ./plugin_requirements.txt /
-   RUN /opt/netbox/venv/bin/pip install --no-warn-script-location -r /plugin_requirements.txt
-   ```
+Vorher kann geprüft werden, ob der Eintrag bereits vorhanden ist:

-4. Create a ``docker-compose.override.yml`` with contents:
+```bash
+grep -qxF "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git" /opt/netbox/local_requirements.txt || \
+  echo "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git" >> /opt/netbox/local_requirements.txt
+```

-   ```
-   version: '3.7'
-   services:
-     netbox:
-       ports:
-         - 8000:8080
-       build:
-         context: .
-         dockerfile: Dockerfile-SLM
-       image: netbox:slm
-     netbox-worker:
-       image: netbox:slm
-     netbox-housekeeping:
-       image: netbox:slm
-   ```
+### 2. Plugin mit Pip installieren

-Now, build the image: ``docker compose build --no-cache``
+Die Installation muss im Python-Virtual-Environment von NetBox erfolgen:

-And finally, run NetBox with the SLM plugin: ``docker compose up``
+```bash
+/opt/netbox/venv/bin/pip install --upgrade --force-reinstall \
+  "git+https://git.mrblake.cc/MrBlake/NetBox-SLM.git"
+```

-## Releasing Guide
+Alternativ können alle lokalen Anforderungen installiert werden:

-To draft a release;
+```bash
+/opt/netbox/venv/bin/pip install -r /opt/netbox/local_requirements.txt
+```

-update the `netbox_slm/__init__.py` file to reflect the new version, then from the *src*
-directory run
+Die installierte Version kann anschließend geprüft werden:

-   ```
-   $ python -m build
-   $ twine upload dist/*
-   ```
+```bash
+/opt/netbox/venv/bin/pip show netbox-slm
+```

-On Github.com create a similar tag and version. These steps could be
-automated with a github workflow.
+Für diese Variante muss dort mindestens Version `1.12.0` stehen.

+## Ablaufbenachrichtigungen

-## Developer Guide (local installation)
+Für Lizenzen mit Ablaufdatum sind Benachrichtigungen standardmäßig aktiviert. Die Standardtermine liegen einen
+Monat und eine Woche vor dem Ablaufdatum. Pro Lizenz kann zusätzlich eine eigene Vorwarnzeit festgelegt oder die
+Standardtermine deaktiviert werden.

-*Follow the steps below on your local system to run netbox and the
-netbox_slm plugin in developer mode*
+Empfänger entscheiden selbst, ob sie informiert werden: Vertrieb, zuständiger Techniker oder andere Benutzer öffnen
+die Lizenz und wählen die NetBox-Aktion **Abonnieren**. Mit **Abonnement beenden** können sie die Meldungen wieder
+abschalten. Ohne Abonnenten wird keine Nachricht versendet.

-### Setup
+Die NetBox-Nachricht wird immer erzeugt. Wird an der Lizenz zusätzlich **E-Mail-Benachrichtigungen** aktiviert, sendet
+das Plugin auch eine E-Mail an die im Benutzerkonto hinterlegte Adresse. Dafür muss der SMTP-Versand in NetBox
+konfiguriert sein.

-The goal below is to run all NetBox components in Docker and run a local
-NetBox Django copy with auto-reload to develop the plugin pointing to
-the Dockerized postgres and redis instances, basically ignoring the
-netbox docker runtime server.
+Die Aktivierung des E-Mail-Versands darf nur durch Administratoren oder Benutzer mit der Berechtigung
+`netbox_slm.manage_softwarelicense_email_notifications` geändert werden. Die eigentlichen SMTP-Zugangsdaten werden
+ausschließlich in der NetBox-Serverkonfiguration gepflegt und sind im Plugin nicht einsehbar.

-### Steps
+Die Prüfung läuft einmal täglich als NetBox-Systemjob. Sobald der erste konfigurierte Erinnerungstermin erreicht ist,
+werden die Abonnenten bei jedem Joblauf erneut informiert: immer über NetBox und bei aktivierter E-Mail-Option
+zusätzlich per SMTP. Dies wird bis einschließlich des Ablaufdatums wiederholt. Der NetBox-RQ-Worker muss dafür mit
+Scheduler-Unterstützung laufen; dies ist bei der regulären NetBox-Installation mit `rqworker` standardmäßig der Fall.

-   from your projects directory clone the netbox repository
+### 3. Plugin in NetBox aktivieren

-   ```
-   $ git clone https://github.com/netbox-community/netbox
-   $ cd netbox
-   ```
-   
-   install the virtual environment
-   
-   ```
-   $ pipenv shell
-   $ pipenv install
-   ```
+In `/opt/netbox/netbox/netbox/configuration.py` ergänzen:

-   create and edit netbox/configuration.py (based on the template file) add these lines at the end of the file;
-   
-   ```
-   DEBUG = True
-   SECRET_KEY = 'dummy'
-   DEVELOPER = True
-   PLUGINS = [
-       'netbox_slm',
-   ]
-   ```
+```python
+PLUGINS = [
+    "netbox_slm",
+]
+```

-The NetBox installation above will be used to run Django management
-commands like runserver, makemigrations and migrate, which will be
-explained in the next steps below;
+Falls bereits andere Plugins eingetragen sind, wird `"netbox_slm"` lediglich zur vorhandenen Liste hinzugefügt.
+Eine zusätzliche `PLUGINS_CONFIG`-Konfiguration ist für den Standardbetrieb nicht erforderlich.

-   from your projects directory clone the netbox-slm repository
+### 4. Datenbank migrieren und statische Dateien aktualisieren

-   ```
-   $ git clone https://github.com/ICTU/netbox_slm
-   $ cd netbox_slm
-   $ ./start-netbox.sh
-   ```
-   
-This will start NetBox locally (requires Docker) and forward the redis
-and postgres ports to the localhost (make sure there’s no processes
-using these ports or change the dockerfiles accordingly)
+```bash
+cd /opt/netbox/netbox
+/opt/netbox/venv/bin/python manage.py migrate
+/opt/netbox/venv/bin/python manage.py collectstatic --no-input
+```

-Note, you can also start and stop netbox by hand:
+### 5. NetBox-Dienste neu starten

-   ```
-   $ cd netbox-docker
-   $ docker-compose up -d
-   ```
-   
-   or stop the stack with
+Bei einer üblichen systemd-Installation:

-   ```
-   $ docker-compose down
-   ```
-   
-   # to start fresh:
+```bash
+sudo systemctl restart netbox netbox-rq
+```

-   ```
-   $ docker-compose down
-   $ docker volume rm netbox-docker_netbox-postgres-data  # et cetera
-   $ docker-compose up -d --force-recreate
-   ```
-   
-   this will require you to re-run the migrate commando's for netbox-slm, see further down below
+Je nach Installation können die Namen der Dienste abweichen.

-Go back to the netbox configuration.py file and update the postgres and
-redis connection strings (username, password) to the ones the netbox
-docker backend is using, for example (using default user and passwords
-from the netbox docker example):

-   
-Now you can run commands from the netbox repository like this;
+1. `"netbox_slm"` aus der `PLUGINS`-Liste entfernen.
+2. Die Git-Zeile aus `/opt/netbox/local_requirements.txt` entfernen.
+3. Das Python-Paket deinstallieren:

-   ```
-   $ cd netbox/netbox
-   $ export PYTHONPATH=../../netbox_slm/netbox_slm/  # or with the pipenv activated run `python3 setup.py develop` from the netbox_slm directory
-   $ python3 manage.py migrate netbox_slm
-   $ python3 manage.py runserver 8001
-   ```
+```bash
+/opt/netbox/venv/bin/pip uninstall netbox-slm
+```

-Visit http://127.0.0.1:8001 in the browser to see the auto reloading
-version of the netbox UI. Port 8000 is taken by the docker ran variant.
+Die Plugin-Tabellen werden dabei nicht automatisch aus der Datenbank gelöscht.
