### Adding Isabellenhuette Library to LibrePCB Projects (Local & System-wide)

Source: https://context7.com/librepcb-libraries/isabellenhuette.lplib/llms.txt

These commands illustrate how to integrate the Isabellenhuette library into a LibrePCB project. It covers cloning the library repository to either the local user's library directory or the system-wide library directory, enabling its use within LibrePCB.

```bash
# Clone the library to your LibrePCB libraries directory
cd ~/.local/share/librepcb/libraries/local/
git clone https://github.com/LibrePCB-Libraries/Isabellenhuette.lplib

# Or for system-wide installation
cd /usr/share/librepcb/libraries/
sudo git clone https://github.com/LibrePCB-Libraries/Isabellenhuette.lplib
```

### GitHub Actions CI Workflow for LibrePCB Library Validation

Source: https://context7.com/librepcb-libraries/isabellenhuette.lplib/llms.txt

This workflow automates the validation of the LibrePCB library using the LibrePCB CLI. It runs on push and pull request events, utilizing a Docker container with the specified LibrePCB CLI version to perform checks. Dependencies include the `actions/checkout@v1` action and the `librepcb/librepcb-cli:1.0.0-rc1` Docker image.

```yaml
name: CI
on: [push, pull_request]
jobs:
  check:
    runs-on: ubuntu-22.04
    container:
      image: librepcb/librepcb-cli:1.0.0-rc1
      options: --entrypoint /bin/bash
    steps:
    - uses: actions/checkout@v1
    - run: librepcb-cli open-library --all --strict --check --minify-step .
```

### Local Validation of LibrePCB Library using Docker

Source: https://context7.com/librepcb-libraries/isabellenhuette.lplib/llms.txt

This command sequence demonstrates how to validate the LibrePCB library locally using Docker. It involves pulling the necessary Docker image and then running the library validation command, mounting the current directory to the container. The validation checks all components, packages, and devices within the library for strict compliance.

```bash
# Install LibrePCB CLI
docker pull librepcb/librepcb-cli:1.0.0-rc1

# Run library validation (checks all components, packages, and devices)
docker run --rm -v $(pwd):/library librepcb/librepcb-cli:1.0.0-rc1 \
  open-library --all --strict --check --minify-step /library

# Expected output on success:
# Open library '/library'...
# Check library elements...
# All checks passed!
```
