See doc/install.txt in the source code archive for general information. Except the given information there, please take note of the following:
Python 2.7.2 or later is needed. It doesn't work with Python 3 yet, see #40 for details.
The version in the pip repository is old. Instead, use the current git master version via pip install git+https://github.com/linkchecker/linkchecker.git. See #4.
Windows builds are seriously lagging behind the Linux releases, see #53 for details. For now, the only two options are to install from source or use Docker for Windows.
Execute linkchecker http://www.example.com.
For other options see linkchecker --help.
If you do not want to install any additional libraries/dependencies you can use the Docker image.
Example for external web site check:
`
docker run --rm -it -u $(id -u):$(id -g) linkchecker/linkchecker --verbose https://google.com
`
Local HTML file check:
`
docker run --rm -it -u $(id -u):$(id -g) -v "$PWD":/mnt linkchecker/linkchecker --verbose index.html
