-# WEBHOOK FOR [DOLIBARR ERP CRM](https://www.dolibarr.org)
-
-## Features
-
-Description of the module...
-
-<!--
-![Screenshot webhook](img/screenshot_webhook.png?raw=true "Webhook"){imgmd}
--->
-
-Other external modules are available on [Dolistore.com](https://www.dolistore.com).
-
-## Translations
-
-Translations can be completed manually by editing files into directories *langs*.
-
-<!--
-This module contains also a sample configuration for Transifex, under the hidden directory [.tx](.tx), so it is possible to manage translation using this service.
-
-For more informations, see the [translator's documentation](https://wiki.dolibarr.org/index.php/Translator_documentation).
-
-There is a [Transifex project](https://transifex.com/projects/p/dolibarr-module-template) for this module.
--->
-
-<!--
-
-## Installation
-
-### From the ZIP file and GUI interface
-
-If the module is a ready to deploy zip file, so with a name module_xxx-version.zip (like when downloading it from a market place like [Dolistore](https://www.dolistore.com)),
-go into menu ```Home - Setup - Modules - Deploy external module``` and upload the zip file.
-
-Note: If this screen tell you that there is no "custom" directory, check that your setup is correct:
-
-- In your Dolibarr installation directory, edit the ```htdocs/conf/conf.php``` file and check that following lines are not commented:
-
-    ```php
-    //$dolibarr_main_url_root_alt ...
-    //$dolibarr_main_document_root_alt ...
-    ```
-
-- Uncomment them if necessary (delete the leading ```//```) and assign a sensible value according to your Dolibarr installation
-
-    For example :
-
-    - UNIX:
-        ```php
-        $dolibarr_main_url_root_alt = '/custom';
-        $dolibarr_main_document_root_alt = '/var/www/Dolibarr/htdocs/custom';
-        ```
-
-    - Windows:
-        ```php
-        $dolibarr_main_url_root_alt = '/custom';
-        $dolibarr_main_document_root_alt = 'C:/My Web Sites/Dolibarr/htdocs/custom';
-        ```
-
-### From a GIT repository
-
-Clone the repository in ```$dolibarr_main_document_root_alt/webhook```
-
-```sh
-cd ....../custom
-git clone git@github.com:gitlogin/webhook.git webhook
-```
-
-### <a name="final_steps"></a>Final steps
-
-From your browser:
-
-  - Log into Dolibarr as a super-administrator
-  - Go to "Setup" -> "Modules"
-  - You should now be able to find and enable the module
