You've found something unclear in the documentation and want to give a try at explaining it better? Let's see how.

Building Documentation

General

This documentation is built with mkdocs.

Method 1: Docker and make

You can build the documentation and test it locally (with live reloading), using the docs-serve target:

$ make docs-serve
docker build -t traefik-docs -f docs.Dockerfile .
# […]
docker run  --rm -v /home/user/go/github/traefik/traefik:/mkdocs -p 8000:8000 traefik-docs mkdocs serve
# […]
[I 170828 20:47:48 server:283] Serving on http://0.0.0.0:8000
[I 170828 20:47:48 handlers:60] Start watching changes
[I 170828 20:47:48 handlers:62] Start detecting changes

!!! tip "Default URL"

Your local documentation server will run by default on <http://127.0.0.1:8000>.

If you only want to build the documentation without serving it locally, you can use the following command:

$ make docs-build
...

Method 2: mkdocs

First, make sure you have python and pip installed.

$ python --version
Python 2.7.2
$ pip --version
pip 1.5.2

Then, install mkdocs with pip.

pip install --user -r requirements.txt

To build the documentation locally and serve it locally, run mkdocs serve from the root directory. This will start a local server.

$ mkdocs serve

INFO    -  Cleaning site directory

Check the Documentation

To check that the documentation meets standard expectations (no dead links, html markup validity, ...), use the docs-verify target.

$ make docs-verify
docker build -t traefik-docs-verify ./script/docs-verify-docker-image ## Build Validator image
...
docker run --rm -v /home/travis/build/traefik/traefik:/app traefik-docs-verify ## Check for dead links and w3c compliance

!!! note "Clean & Verify"

If you've made changes to the documentation, it's safter to clean it before verifying it.

```bash
$ make docs
...
```

Will perform all necessary steps for you.

!!! note "Disabling Documentation Verification"

Verification can be disabled by setting the environment variable `DOCS_VERIFY_SKIP` to `true`:

```shell
DOCS_VERIFY_SKIP=true make docs-verify
...
DOCS_LINT_SKIP is true: no linting done.
```
