-# Contributor Covenant Code of Conduct
-
-## Our Pledge
-
-In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
-
-## Our Standards
-
-Examples of behavior that contributes to creating a positive environment include:
-
-* Using welcoming and inclusive language
-* Being respectful of differing viewpoints and experiences
-* Gracefully accepting constructive criticism
-* Focusing on what is best for the community
-* Showing empathy towards other community members
-
-Examples of unacceptable behavior by participants include:
-
-* The use of sexualized language or imagery and unwelcome sexual attention or advances
-* Trolling, insulting/derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or electronic address, without explicit permission
-* Other conduct which could reasonably be considered inappropriate in a professional setting
-
-## Our Responsibilities
-
-Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
-
-Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
-
-## Scope
-
-This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at neuhart.julien@gmail.com. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
-
-Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
-
-## Attribution
-
-This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

-At TheCodingMachine, we build a lot of web applications (intranets, extranets and so on) which require to generate PDF from various sources. Each time, we ended up using some well known libraries and kind of lost time by reimplementing a solution from a project to another project. Meh.
+Gotenberg provides a developer-friendly API to interact with powerful tools like Chromium and LibreOffice for converting 
+numerous document formats (HTML, Markdown, Word, Excel, etc.) into PDF files, and more!
 
-## Features
+## Quick Start
-
-* HTML and Markdown conversions using Google Chrome headless
-* Office conversions (.txt, .rtf, .docx, .doc, .odt, .pptx, .ppt, .odp and so on) using [unoconv](https://github.com/dagwieers/unoconv)
-* Performance :zap:: Google Chrome and LibreOffice (unoconv) started once in the background thanks to PM2
-* Failure prevention :broken_heart:: PM2 automatically restarts previous processes if they fail
-* Assets :package:: send your header, footer, images, fonts, stylesheets and so on for converting your HTML and Markdown to beaufitul PDFs!
-* Easily interact with the API using our [Go](https://github.com/thecodingmachine/gotenberg-go-client) and [PHP](https://github.com/thecodingmachine/gotenberg-php-client) libraries
-
-## Quick start
 
 Open a terminal and run the following command:
 
-```bash
+```
-$ docker run --rm -p 3000:3000 thecodingmachine/gotenberg:5
+docker run --rm -p 3000:3000 gotenberg/gotenberg:7
 ```
 
-The API is now available on your host at `http://localhost:3000`.
+Alternatively, using the historic Docker repository from our sponsor [TheCodingMachine](https://www.thecodingmachine.com):
 
-Head to the [documentation](https://thecodingmachine.github.io/gotenberg)
+```
-to learn how to interact with it!
+docker run --rm -p 3000:3000 thecodingmachine/gotenberg:7
+```
+
+The API is now available on your host at http://localhost:3000.
+
+Head to the [documentation](https://gotenberg.dev/docs/about) to learn how to interact with it 🚀

-Gotenberg is shipped within a Docker image.
-
-You may start it with:
-
-```bash
-$ docker run --rm -p 3000:3000 thecodingmachine/gotenberg:5
-```
-
-> The API will be available at [http://localhost:3000](http://localhost:3000).
-
-## Docker Compose
-
-You may also add it in your Docker Compose stack:
-
-```yaml
-version: '3'
-
-services:
-
-  # your others services
-
-  gotenberg:
-    image: thecodingmachine/gotenberg:5
-```
-
-> The API will be available under `gotenberg:3000` in your Docker Compose network.
-
-## Kubernetes
-
-It may also be deployed with Kubernetes.
-
-Make sure to provide enough memory and CPU requests (for instance `512Mi` and `0.2` CPU).
-Otherwise the API will not be able to launch Google Chrome and LibreOffice (unoconv).
-
-> The more resources are granted, the quicker will be the conversions.

----
-title: Environment variables
----
-
-You may customize the API behaviour thanks to environment variables.
-
-## Disable Google Chrome
-
-In order to save some resources, the Gotenberg image accepts the environment variable `DISABLE_GOOGLE_CHROME`.
-
-It takes the strings `"0"` or `"1"` as value.
-
-> If Google Chrome is disabled, the following conversions will **not** be available anymore:
-> [HTML](#html), [URL](#url) and [Markdown](#markdown)
-
-
-## Disable LibreOffice (unoconv)
-
-You may also disable LibreOffice (unoconv) with `DISABLE_UNOCONV`.
-
-> If LibreOffice (unoconv) is disabled, the following conversion will **not** be available anymore:
-> [Office](#office)
-
-## Default wait timeout
-
-By default, the API will wait 10 seconds before it considers the conversion to be unsuccessful.
-
-You may customize this timeout thanks to the environment variable `DEFAULT_WAIT_TIMEOUT`.
-
-It takes a string representation of a float as value (e.g `"2.5"` for 2.5 seconds).
-
-> The default timeout may also be overridden per request thanks to the form field `waitTimeout`.
-> See the [timeout section](#timeout).

-
-Gotenberg provides the endpoint `/convert/html` for HTML conversions.
-
-It accepts `POST` requests with a `multipart/form-data` Content-Type.
-
-## Basic
-
-The only requirement is to send a file named `index.html`: it is the file
-which will be converted to PDF.
-
-For instance:
-
-```html
-<!doctype html>
-<html lang="en">
-  <head>
-    <meta charset="utf-8">
-    <title>My PDF</title>
-  </head>
-  <body>
-    <h1>Hello world!</h1>
-  </body>
-</html>
-```
-
-### cURL
-
-```bash
-$ curl --request POST \
-    --url http://localhost:3000/convert/html \
-    --header 'Content-Type: multipart/form-data' \
-    --form files=@index.html \
-    -o result.pdf
-```
-
-### Go
-
-```golang
-import "github.com/thecodingmachine/gotenberg-go-client/v5"
-
-func main() {
-    c := &gotenberg.Client{Hostname: "http://localhost:3000"}
-    req, _ := gotenberg.NewHTMLRequest("index.html")
-    dest := "result.pdf"
-    c.Store(req, dest)
-}
-```
-
-### PHP
-
-```php
-use TheCodingMachine\Gotenberg\Client;
-use TheCodingMachine\Gotenberg\DocumentFactory;
-use TheCodingMachine\Gotenberg\HTMLRequest;
-
-$client = new Client('http://localhost:3000', new \Http\Adapter\Guzzle6\Client());
-$index = DocumentFactory::makeFromPath('index.html', 'index.html');
-$request = new HTMLRequest($index);
-$dirPath = "/foo";
-$filename = $client->store($request, $dirPath);
-```
-
-## Header and footer
-
-You may also add a header and/or a footer in the resulting PDF.
-Respectively, a file named `header.html` and `footer.html`.
-
-Each of them **has to be a complete HTML document**:
-
-```html
-<html>
-    <head>
-        <style>
-            body {
-                font-size: 8rem;
-                margin: 4rem auto;
-            }
-        </style>
-    </head>
-    <body>
-        <p>
-            <span class="pageNumber"></span> of <span class="totalPages"></span>
-        </p>
-    </body>
-</html>
-```
-
-The following classes allow you to inject printing values:
-
-* `date`: formatted print date
-* `title`: document title
-* `pageNumber`: current page number
-* `totalPage`: total pages in the document
-
-> **Attention:** the CSS properties are independant of the ones used in the `index.html` file.
-> Also, `footer.html` CSS properties override the ones from `header.html`.
