## How ClickHouse documentation is generated? {#how-clickhouse-documentation-is-generated}
|
||
|
||
ClickHouse documentation is built using [build.py](build.py) script that uses [mkdocs](https://www.mkdocs.org) library and it’s dependencies to separately build all version of documentations (all languages in either single and multi page mode) as static HTMLs and then a PDF for each single page version. The results are then put in the correct directory structure. It is recommended to use Python 3.7 to run this script.
|
||
|
||
[release.sh](release.sh) also pulls static files needed for [official ClickHouse website](https://clickhouse.tech) from [../../website](../../website) folder then pushes to specified GitHub repo to be served via [GitHub Pages](https://pages.github.com).

## How to check if the documentation will look fine? {#how-to-check-if-the-documentation-will-look-fine}
|
||
|
||
There are few options that are all useful depending on how large or complex your edits are.
|
||
|
||
### Use GitHub web interface to edit
|
||
|
||
GitHub has Markdown support with preview feature, but the details of GitHub Markdown dialect are a bit different in ClickHouse documentation.
|
||
|
||
### Install Markdown editor or plugin for your IDE {#install-markdown-editor-or-plugin-for-your-ide}
|
||
|
||
Usually those also have some way to preview how Markdown will look like, which allows to catch basic errors like unclosed tags very early.
|
||
|
||
### Use build.py {#use-build-py}
|
||
|
||
It’ll take some effort to go through, but the result will be very close to production documentation.
|
||
|
||
For the first time you’ll need to install [wkhtmltopdf](https://wkhtmltopdf.org/) and set up virtualenv:
|
||
|
||
``` bash
|
||
$ cd ClickHouse/docs/tools
|
||
$ mkdir venv
|
||
$ virtualenv -p $(which python3) venv
|
||
$ source venv/bin/activate
|
||
$ pip3 install -r requirements.txt
|
||
```
|
||
|
||
Then running `build.py` without args (there are some, check `build.py --help`) will generate `ClickHouse/docs/build` folder with complete static html website.
|
||
|
||
The easiest way to see the result is to use `--livereload=8888` argument of build.py. Alternatively, you can manually launch a HTTP server to serve the docs, for example by running `cd ClickHouse/docs/build && python3 -m http.server 8888`. Then go to http://localhost:8888 in browser. Feel free to use any other port instead of 8888.

## How to subscribe on documentation changes? {#how-to-subscribe-on-documentation-changes}
|
||
|
||
At the moment there’s no easy way to do just that, but you can consider:
|
||
|
||
- To hit the “Watch” button on top of GitHub web interface to know as early as possible, even during pull request. Alternative to this is `#github-activity` channel of [public ClickHouse Slack](https://join.slack.com/t/clickhousedb/shared_invite/enQtOTUzMjM4ODQwNTc5LWJmMjE3Yjc2YmI1ZDBlZmI4ZTc3OWY3ZTIwYTljYzY4MzBlODM3YzBjZTc1YmYyODRlZTJkYTgzYzBiNTA2Yjk).
|
||
- Some search engines allow to subscribe on specific website changes via email and you can opt-in for that for https://clickhouse.tech.
