# Documentation Features Are Better When You Know How to Use Them {: .subtitle } 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](https://doc.traefik.io/traefik/) is built with [mkdocs](https://mkdocs.org/). ### Method 1: `Docker` and `make` You can build the documentation and test it locally (with live reloading), using the `docs` target: ```bash $ make docs 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](http://127.0.0.1:8000). If you only want to build the documentation without serving it locally, you can use the following command: ```bash $ make docs-build ... ``` ### Method 2: `mkdocs` First, make sure you have `python` and `pip` installed. ```bash $ python --version Python 2.7.2 $ pip --version pip 1.5.2 ``` Then, install mkdocs with `pip`. ```bash 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. ```bash $ mkdocs serve INFO - Building documentation... INFO - Cleaning site directory [I 160505 22:31:24 server:281] Serving on http://127.0.0.1:8000 [I 160505 22:31:24 handlers:59] Start watching changes [I 160505 22:31:24 handlers:61] Start detecting changes ``` ### Check the Documentation To check that the documentation meets standard expectations (no dead links, html markup validity, ...), use the `docs-verify` target. ```bash $ 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 === Checking HTML content... Running ["HtmlCheck", "ImageCheck", "ScriptCheck", "LinkCheck"] on /app/site/basics/index.html on *.html... ``` !!! note "Clean & Verify" If you've made changes to the documentation, it's safter to clean it before verifying it. ```bash $ make docs-clean docs-verify ... ``` !!! 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. ```
