-
-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 like **wkhtmltopdf** or **unoconv** and kind of lost time by
-reimplementing a solution from a project to another project. Meh.

-
-## Usage
-
-Let's say you're starting the API using this simple command:
-
-```sh
-$ docker run --rm -p 3000:3000 thecodingmachine/gotenberg:{{ .Orbit.Latest }}
-```
-
-The API is now available on your host under `http://127.0.0.1:3000`.
-
-It accepts `POST` requests with a `multipart/form-data` Content-Type. Your form data should provide one or more files to convert.
-It currently accepts the following:
-
-* Markdown files
-* HTML files
-* Office documents (.docx, .doc, .odt, .pptx, .ppt, .odp and so on)
-* PDF files (if more than one file to convert)
-
-**Heads up:** the API relies on the file extension to determine which library to use for conversion.
-
-There are two use cases:
-
-* If you send one file, it will convert it and return the resulting PDF
-* If many files, it will convert them to PDF, merge the resulting PDFs into a single PDF and return it
-
-### Examples:
-
-* One file
-
-```sh
-$ curl --request POST \
-    --url http://127.0.0.1:3000 \
-    --header 'Content-Type: multipart/form-data' \
-    --form files=@file.docx \
-    > result.pdf
-```
-
-* Many files
-
-```sh
-$ curl --request POST \
-    --url http://127.0.0.1:3000 \
-    --header 'Content-Type: multipart/form-data' \
-    --form files=@file.md \
-    --form files=@file.html \
-    --form files=@file.pdf \
-    --form files=@file.docx \
-    > result.pdf
-```
-
-## Security
-
-The API does not provide any authentication mechanisms. Make sure to not put it on a public facing port and your client(s) should always 
-controls what is sent to the API.
-
-## Scalability
-
-Some libraries like **unoconv** cannot perform concurrent conversions. That's why the API does only one conversion at a time.
-If your API is under heavy load, a request will take time to be processed. 
-
-Fortunately, you may pass through this limitation by scaling the API.
-
-In the following example, I'll demonstrate how to do some vertical scaling (= on the same machine) with Docker Compose, but of course horizontal scaling works too!
-
-```yaml
-version: '3'
-
-services:
-
-  # your others services
-      
-  gotenberg:
-    image: gotenberg:1.0.0
-```
-
-You may now launch your services using:
-
-```bash
-docker-compose up --scale gotenberg=your_number_of_instances
-```
-
-When requesting the Gotenberg service with your client(s), Docker will automatically redirect a request to a Gotenberg container
-according to the round-robin strategy.
-
-## Custom implementation
-
-The API relies on a simple YAML configuration file called `gotenberg.yml`. It allows you to tweak some values and even provides you 
-a way to change the commands called for each kind of conversion. The configuration file should be located under `/gotenberg` in your container.
-
-The default configuration is located here: [.ci/gotenberg.yml](.ci/gotenberg.yml)
-
-## Clients
-
-* https://github.com/thecodingmachine/gotenberg-php-client (PHP client)
-* Add your own client by submitting a [pull request](../../pulls)!

-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 like **wkhtmltopdf** or **unoconv** and kind of lost time by
-reimplementing a solution from a project to another project. Meh.

+## Features
 
-* [Usage](#usage)
-* [Security](#security)
-* [Scalability](#scalability)
-* [Custom implementation](#custom-implementation)
-* [Clients](#clients)
+* 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)
+* Assets :package:: send your header, footer, images, fonts, stylesheets and so on for converting your HTML and Markdown to beautiful 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
 
-## Usage
+## Quick start
 
-Let's say you're starting the API using this simple command:
-
-```sh
-$ docker run --rm -p 3000:3000 thecodingmachine/gotenberg:1.0.0
-```
-
-The API is now available on your host under `http://127.0.0.1:3000`.
-
-It accepts `POST` requests with a `multipart/form-data` Content-Type. Your form data should provide one or more files to convert.
-It currently accepts the following:
-
-* Markdown files
-* HTML files
-* Office documents (.docx, .doc, .odt, .pptx, .ppt, .odp and so on)
-* PDF files (if more than one file to convert)
-
-**Heads up:** the API relies on the file extension to determine which library to use for conversion.
-
-There are two use cases:
-
-* If you send one file, it will convert it and return the resulting PDF
-* If many files, it will convert them to PDF, merge the resulting PDFs into a single PDF and return it
-
-### Examples:
-
-* One file
-
-```sh
-$ curl --request POST \
-    --url http://127.0.0.1:3000 \
-    --header 'Content-Type: multipart/form-data' \
-    --form files=@file.docx \
-    > result.pdf
-```
-
-* Many files
-
-```sh
-$ curl --request POST \
-    --url http://127.0.0.1:3000 \
-    --header 'Content-Type: multipart/form-data' \
-    --form files=@file.md \
-    --form files=@file.html \
-    --form files=@file.pdf \
-    --form files=@file.docx \
-    > result.pdf
-```
-
-## Security
-
-The API does not provide any authentication mechanisms. Make sure to not put it on a public facing port and your client(s) should always 
-controls what is sent to the API.
-
-## Scalability
-
-Some libraries like **unoconv** cannot perform concurrent conversions. That's why the API does only one conversion at a time.
-If your API is under heavy load, a request will take time to be processed. 
-
-Fortunately, you may pass through this limitation by scaling the API.
-
-In the following example, I'll demonstrate how to do some vertical scaling (= on the same machine) with Docker Compose, but of course horizontal scaling works too!
-
-```yaml
-version: '3'
-
-services:
-
-  # your others services
-      
-  gotenberg:
-    image: gotenberg:1.0.0
-```
-
-You may now launch your services using:
+Open a terminal and run the following command:
 
 ```bash
-docker-compose up --scale gotenberg=your_number_of_instances
+$ docker run --rm -p 3000:3000 thecodingmachine/gotenberg:6
 ```
 
-When requesting the Gotenberg service with your client(s), Docker will automatically redirect a request to a Gotenberg container
-according to the round-robin strategy.
+The API is now available on your host at `http://localhost:3000`.
 
-## Custom implementation
+Head to the [documentation](https://thecodingmachine.github.io/gotenberg)
+to learn how to interact with it!
 
-The API relies on a simple YAML configuration file called `gotenberg.yml`. It allows you to tweak some values and even provides you 
-a way to change the commands called for each kind of conversion. The configuration file should be located under `/gotenberg` in your container.
+## Badges
 
-The default configuration is located here: [.ci/gotenberg.yml](.ci/gotenberg.yml)
-
-## Clients

-* https://github.com/thecodingmachine/gotenberg-php-client (PHP client)
-* Add your own client by submitting a [pull request](../../pulls)!

+
+[Gotenberg](https://github.com/thecodingmachine/gotenberg/) is a Docker-powered stateless API for converting HTML, Markdown and Office documents to PDF.
+
+* 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)
+* Assets: 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

build/docs/content/01-install.md

@@ -0,0 +1,71 @@

+title: Install
+---
+
+Gotenberg is shipped within a Docker image.
+
+You may start it with:
+
+```bash
+$ docker run --rm -p 3000:3000 thecodingmachine/gotenberg:6
+```
+
+> The API will be available at [http://localhost:3000](http://localhost:3000).
+
+The image uses a dedicated non-root user called `gotenberg` with uid and gid `1001`.
+
+If you wish to change those uid and gid, you will have to:
+
+* clone the project
+* re-build the image
+* publish the image in your own Docker registry
+
+For instance:
+
+```bash
+$ git clone https://github.com/thecodingmachine/gotenberg.git
+$ make publish GOTENBERG_USER_GID=your_custom_gid GOTENBERG_USER_UID=your_custom_uid DOCKER_REGISTRY=your_registry DOCKER_USER=registry_user DOCKER_PASSWORD=registry_password VERSION=version
+```
+
+> `master` branch is always up-to-date with the latest version of the API.
+
+## Docker Compose
+
+You may also add it in your Docker Compose stack:
+
+```yaml
+version: '3'
+
+services:
+
+  # your other services
+
+  gotenberg:
+    image: thecodingmachine/gotenberg:6
+```
+
+> 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).
+
+> The more resources are granted, the quicker will be the conversions.
+
+In the deployment specification of the pod, also specify the uid of the user `gotenberg`:
+
+```
+securityContext:
+  privileged: false
+  runAsUser: 1001
+```
+
+## Cloud Run (Google Cloud)
+
+If you're looking for cost savings, you might be interested by [Cloud Run](https://cloud.google.com/run).
+However, according to some users, doing asynchronous conversion (with a webhook) might not working.
+
+In the following examples, we will assume your
+Gotenberg API is available at [http://localhost:3000](http://localhost:3000).

+title: Environment variables
+---
+
+You may customize the API behaviour thanks to environment variables.
+
+## Log level
+
+The API provides structured logging allowing you to have relevant information
+about what's going on.
+
+> If a TTY is attached, the log entries are displayed in text format with colors, otherwise in JSON format.
+
+You may customize the severity of the log entries thanks to the environment variable `LOG_LEVEL`.
+
+It accepts one of the following severities: `"DEBUG"`, `"INFO"` (default) and `"ERROR"`.
+
+## Default listen port
+
+By default, the API will listen on port `3000`.
+
+You may customize this value with the environment variable `DEFAULT_LISTEN_PORT`.
+
+This environment variable accepts any string that can be turned into a port number.
+
+## Root path
+
+By default, the API root path is `/`.
+
+You may customize this value with the environment variable `ROOT_PATH`.
+
+This environment variable accepts a string starting and ending with `/`.
+
+For instance, `/gotenberg/` is a valid value while `gotenberg` is not.
+
+> This is useful if you wish to do service discovery via URL paths.
+
+## Disable Google Chrome
+
+In order to save some resources, the Gotenberg image accepts the environment variable `DISABLE_GOOGLE_CHROME`
+for disabling Google Chrome.
+
+It takes the strings `"0"` or `"1"` as value where `1` means `true`
+
+> If Google Chrome is disabled, the following conversions will **not** be available anymore:
+> [HTML](#html), [URL](#url) and [Markdown](#markdown)
+
+## Default Google Chrome rpcc buffer size
+
+When performing a [HTML](#html), [URL](#url) or [Markdown](#markdown) conversion, the API might return
+a `400` HTTP code with the message `increase the Google Chrome rpcc buffer size`.
+
+If so, you may increase this buffer size with the environment variable `DEFAULT_GOOGLE_CHROME_RPCC_BUFFER_SIZE`.
+
+It takes a string representation of an int as value (e.g. `"1048576"` for 1 MB).
+The hard limit is 100 MB and is defined by Google Chrome itself.
+
+> The default Google Chrome rpcc buffer size may also be overridden per request thanks to the form field `googleChromeRpccBufferSize`.
+> See the [rpcc buffer size section](#html.rpcc_buffer_size).
+
+## Google Chrome ignore certificate errors
+
+When performing a [URL](#url) conversion, Google Chrome will not accept certificate errors. 
+
+You may allow insecure connections by setting the `GOOGLE_CHROME_IGNORE_CERTIFICATE_ERRORS` environment variable to `"1"`.
+
+**You should be careful with this feature and only enable it in your development environment.**
+
+## 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.
+If unsucessful, it returns a `504` HTTP code.
+
+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).
+
+## Maximum wait timeout
+
+By default, the value of the form field `waitTimeout` cannot be more than 30 seconds.
+
+You may increase or decrease this limit thanks to the environment variable `MAXIMUM_WAIT_TIMEOUT`.
+
+It takes a string representation of a float as value (e.g `"2.5"` for 2.5 seconds).
+
+## Default webhook URL timeout
+
+By default, the API will wait 10 seconds before it considers the sending of the resulting PDF to be unsuccessful.
+
+> See the [webhook section](#webhook).
+
+You may customize this timeout thanks to the environment variable `DEFAULT_WEBHOOK_URL_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 `webhookURLTimeout`.
+> See the [webhook timeout section](#webhook.timeout).
+
+## Maximum webhook URL timeout
+
+By default, the value of the form field `webhookURLTimeout` cannot be more than 30 seconds.
+
+You may increase or decrease this limit thanks to the environment variable `MAXIMUM_WEBHOOK_URL_TIMEOUT`.
+
+It takes a string representation of a float as value (e.g `"2.5"` for 2.5 seconds).
+
+## Maximum wait delay
+
+By default, the value of the form field `waitDelay` cannot be more than 10 seconds.
+
+> See the [wait delay section](#html.wait_delay).
+
+You may increase or decrease this limit thanks to the environment variable `MAXIMUM_WAIT_DELAY`.
+
+It takes a string representation of a float as value (e.g `"2.5"` for 2.5 seconds).

+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>

+    --url http://localhost:3000/convert/html \
+    --header 'Content-Type: multipart/form-data' \
+    --form files=@index.html \
+    -o result.pdf
+```

+index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
+req := gotenberg.NewHTMLRequest(index)
+dest := "result.pdf"

+$index = DocumentFactory::makeFromPath('index.html', '/path/to/file');
+$request = new HTMLRequest($index);
+$dest = 'result.pdf';
+$client->store($request, $dest);
+```
+
+## 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
+
+There are some limitations:
+
+* JavaScript is not executed
+* external resources are not loaded
+* the CSS properties are independant of the ones used in the `index.html` file
+* `footer.html` CSS properties override the ones from `header.html`
+* only fonts installed in the Docker image are loaded (see the [fonts section](#fonts))
+* images only work using a `base64` encoded source (`<img src="data:image/png;base64, iVBORw0K... />`)
+* `background-color` and `color` CSS properties require an additional `-webkit-print-color-adjust: exact` CSS property in order to work

+You may also send additional files. For instance: images, fonts, stylesheets and so on.
+
+The only requirement is to make sure that their paths
+are on the same level as the `index.html` file.
+
+In other words, this will work:
+
+```html
+<!doctype html>
+<html lang="en">
+  <head>
+    <meta charset="utf-8">
+    <title>My PDF</title>
+  </head>
+  <body>
+    <h1>Hello world!</h1>
+    <img src="img.png">
+  </body>
+</html>
+```
+
+But this won't:
+
+```html
+<!doctype html>
+<html lang="en">
+  <head>
+    <meta charset="utf-8">
+    <title>My PDF</title>
+  </head>
+  <body>
+    <h1>Hello world!</h1>
+    <img src="/foo/img.png">
+  </body>
+</html>
+```
+
+You may also use *remote* paths for Google fonts, images and so on.
+
+> If you want to install fonts directly in the Gotenberg Docker image,
+> see to the [fonts section](#fonts).

+title: Webhook
+---
+
+All endpoints accept a form field named `webhookURL`.
+
+If provided, the API will send the resulting PDF file in a `POST` request with the `application/pdf` Content-Type
+to given URL.
+
+By doing so, your requests to the API will be over before the conversions are actually done!
+
+## Examples
+
+### cURL
+
+```bash
+$ curl --request POST \
+    --url http://localhost:3000/convert/html \
+    --header 'Content-Type: multipart/form-data' \
+    --form files=@index.html \
+    --form webhookURL='http://myapp.com/webhook/'
+```
+
+### Go
+
+```golang
+import "github.com/thecodingmachine/gotenberg-go-client/v7"
+
+c := &gotenberg.Client{Hostname: "http://localhost:3000"}
+index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
+req := gotenberg.NewHTMLRequest(index)
+req.WebhookURL("http://myapp.com/webhook/")
+resp, _ := c.Post(req)
+```
+
+### 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', '/path/to/file');
+$request = new HTMLRequest($index);
+$request->setWebhookURL('http://myapp.com/webhook/');
+$resp = $client->post($request);
+```
+
+## Timeout
+
+If a `webhookURL` is provided, you may also send a form field named `webhookURLTimeout`.
+
+The API will wait the given **seconds** before it considers the sending of the resulting PDF to be unsucessful.
+
+It takes a float as value (e.g `2.5` for 2.5 seconds).
+
+> You may also define this value globally: see the [environment variables](#environment_variables.default_webhook_url_timeout) section.
+
+### cURL
+
+```bash
+$ curl --request POST \
+    --url http://localhost:3000/convert/html \
+    --header 'Content-Type: multipart/form-data' \
+    --form files=@index.html \
+    --form webhookURL='http://myapp.com/webhook/' \
+    --form webhookURLTimeout=2.5
+```
+
+### Go
+
+```golang
+import "github.com/thecodingmachine/gotenberg-go-client/v7"
+
+c := &gotenberg.Client{Hostname: "http://localhost:3000"}
+index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
+req := gotenberg.NewHTMLRequest(index)
+req.WebhookURL("http://myapp.com/webhook/")
+req.WebhookURLTimeout(2.5)
+resp, _ := c.Post(req)
+```
+
+### 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', '/path/to/file');
+$request = new HTMLRequest($index);
+$request->setWebhookURL('http://myapp.com/webhook/');
+$request->setWebhookURLTimeout(2.5);
+$resp = $client->post($request);
+```
+
+## Custom HTTP headers
+
+You may send your own HTTP headers to the `webhookURL`.
+
+For instance, by adding the HTTP header `Gotenberg-Webhookurl-Your-Header` to your request,
+the API will send a request to the `webhookURL` with the HTTP header `Your-Header`.
+
+> **Attention:** the API uses a canonical format for the HTTP headers:
+> it transforms the first
+> letter and any letter following a hyphen to upper case;
+> the rest are converted to lowercase. For example, the
+> canonical key for `accept-encoding` is `Accept-Encoding`.
+
+### cURL
+
+```bash
+$ curl --request POST \
+    --url http://localhost:3000/convert/html \
+    --header 'Content-Type: multipart/form-data' \
+    --header 'Gotenberg-Webhookurl-Your-Header: Foo' \
+    --form files=@index.html \
+    --form webhookURL='http://myapp.com/webhook/'
+```

+index, _ := gotenberg.NewDocumentFromPath("index.html", "/path/to/file")
+req := gotenberg.NewHTMLRequest(index)
+req.WebhookURL("http://myapp.com/webhook/")
+req.AddWebhookURLHTTPHeader("Your-Header", "Foo")
+resp, _ := c.Post(req)
+```

+title: Scalability
+---
+
+The API uses under the hood intricate programs.
+
+Gotenberg tries to abstract as much complexity as possible but it can
+only do it to a certain extent.
+
+For instance, [Office](#office) and [Merge](#merge) endpoints will start respectively as many LibreOffice (unoconv) and PDTk
+instances as there are requests. The limitation here is the available memory and CPU usage.
+
+On another hand, for the [HTML](#html), [URL](#url) and [Markdown](#markdown) endpoints, the API does only 6 conversions in parallel.
+Indeed, Google Chrome misbehaves if there are too many concurrent conversions.
+
+**The more concurrent requests, the more `504` HTTP codes the API will return.**
+
+> See our [load testing use case](https://github.com/thecodingmachine/gotenberg/tree/master/loadtesting) for more details about the API behaviour under heavy load.
+
+## Strategies
+
+### Increase timeout
+
+You may increase the conversion timeout. In other words, you accept that a conversion takes more time
+if the API is under heavy load.
+
+> See [timeout section](#timeout).
+
+### Scaling
+
+The API being stateless, you may scale it as much as you want.
+
+For instance, using the following Docker Compose file:
+
+```yaml
+version: '3'
+
+services:
+
+  # your other services
+
+  gotenberg:
+    image: thecodingmachine/gotenberg:6
+```
+
+You may now launch your services using:
+
+```bash
+$ docker-compose up --scale gotenberg=your_number_of_instances
+```
+
+When requesting the Gotenberg service with your client(s), Docker will automatically
+redirect a request to a Gotenberg container according to the round-robin strategy.

+title: Ping
+---
+
+Gotenberg provides the endpoint `/ping` for checking the API availability with
+a simple `GET` request.
+
+Currently this endpoint does nothing special. A better way to monitor
+Gotenberg would be by checking the memory usage.
+
+Also, as the API uses under the hood intricate programs, you should
+restart your Gotenberg instances from time to time to ensure a nominal behaviour.
