-Provide an HTTP anthentification over XMPP. Implementation of [XEP-0070](https://xmpp.org/extensions/xep-0070.html).
+Provide an HTTP authentication over XMPP. Implementation of [XEP-0070](https://xmpp.org/extensions/xep-0070.html).
+
+Can be run as a XMPP client or XMPP component.
 
 
-## Compilation
 ### Dependencies
 
  * [go-xmpp](https://git.kingpenguin.tk/chteufleur/go-xmpp) for the XMPP part.
  * [cfg](https://github.com/jimlawless/cfg) for the configuration file.
 
+### Build and run
+
 You must first [install go environment](https://golang.org/doc/install) on your system.
 Then, go into your $GOPATH directory and go get the source code.
 ```sh
 go get git.kingpenguin.tk/chteufleur/HTTPAuthentificationOverXMPP.git
 ```
 
+First, you need to go into directory ``$GOPATH/src/chteufleur/HTTPAuthentificationOverXMPP.git``.
+Then, you can run the project directly by using command ``go run main.go``.
+Or, in order to build the project you can run the command ``go build main.go``.
+It will generate a binary that you can run as any binary file.
+
 ### Configure
-Configure the gateway by editing the ``httpAuth.cfg`` file in order to give all XMPP component and HTTP server informations.
-An example of the config file can be found in [the repos](https://git.kingpenguin.tk/chteufleur/HTTPAuthentificationOverXMPP/src/master/httpAuth.cfg).
+Configure the gateway by editing the ``httpAuth.conf`` file in order to give all XMPP and HTTP server informations. This configuration file has to be placed following the [XDG specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html) (example ``/etc/xdg/http-auth/httpAuth.conf``).
+An example of the config file can be found in [the repos](https://git.kingpenguin.tk/chteufleur/HTTPAuthentificationOverXMPP/src/master/httpAuth.conf).
 
 XMPP
  * xmpp_server_address : Component server address connection (default: 127.0.0.1)
  * xmpp_server_port : Component server port connection (default: 5347)
- * xmpp_hostname : Component hostname
- * xmpp_secret : Component password
+ * __xmpp_jid__ : Account JID
+ * __xmpp_secret__ : Account password
  * xmpp_debug : Enable debug log at true (default: false)
+ * xmpp_verify_cert_validity : Enable certificate verification (default: true)
+ * xmpp_default_lang : Message default languages
 
 HTTP
- * http_port : HTTP port to bind (default: 9090, desactive: -1)
- * https_port : HTTPS port to bind (default: 9093, desactive: -1)
+ * http_port : HTTP port to bind (default: -1, desactive: -1)
+ * https_port : HTTPS port to bind (default: -1, desactive: -1)
  * https_cert_path : Path to the certificate file (default: ./cert.pem)
  * https_key_path : Path to the key file (default: ./key.pem)
- * http_timeoute_sec : Define a timeout if user did not give an answer to the request (default: 60)
+ * http_timeout_sec : Define a timeout if user did not give an answer to the request (default: 60)
+ * http_bind_address_ipv4 : Bind address on IPv4 (default: 127.0.0.1)
+ * http_bind_address_ipv6 : Bind address on IPv6 (default: [::1])
 
+__Bold config__ are mandatory.
 
-### Utilization
+If ``http_bind_address_ipv4`` is set to ``0.0.0.0``, it will bind all address on IPv4 __AND__ IPv6.
+
+The lang messages file must be placed into the same directory than the configuration file.
+An example of this file can be found in [the repos](https://git.kingpenguin.tk/chteufleur/HTTPAuthentificationOverXMPP/src/master/messages.lang)
+
+### Usage
 To ask authorization, just send an HTTP request to the path ``/auth`` with parameters:
  * __jid__ : JID of the user (user@host/resource or user@host)
  * __domain__ : Domain you want to access
  * __method__ : Method you access the domain
- * transaction_id : Transaction identifier (auto generated if not provide)
+ * __transaction_id__ : Transaction identifier (auto generated if not provide)
  * timeout : Timeout of the request in second (default : 60, max : 300)
 
 __Bold parameters__ are mandatory.
 
 Example:
 ```
-GET /auth?jid=user%40host%2fresource&domain=example.org&method=POST&transaction_id=WhatEverYouWant&timeout=120 HTTP/1.1
+GET /auth?jid=user%40host%2fresource;domain=example.org;method=POST;transaction_id=WhatEverYouWant;timeout=120 HTTP/1.1
 ```
 
 This will send a request to the given JID, then return HTTP code depending on what appended.

+# Packaging
+
+## Build libraries as shared
+
+In order to packaged the project, you will need to follow those different steps.
+We will build libraries as shared libraries.
+
+The first step is to buid the GO standard library as shared.
+```
+$ cd $GOPATH
+$ go install -buildmode=shared std
+```
+
+Next, we will build the 2 libraries to make them shared…
+```
+$ cd $GOPATH
+$ go install -buildmode=shared -linkshared github.com/jimlawless/cfg
+$ go install -buildmode=shared -linkshared git.kingpenguin.tk/chteufleur/go-xmpp.git/src/xmpp
+```
+
+Then finally, build the project with the option that tell to use libraries as shared and not static.
+```
+$ cd $GOPATH
+$ go install -linkshared git.kingpenguin.tk/chteufleur/HTTPAuthentificationOverXMPP.git
+```
+
+You will find shared libraries over here :
+ * ``$GOROOT/pkg/linux_amd64_dynlink/libstd.so``
+ * ``$GOPATH/pkg/linux_amd64_dynlink/libgithub.com-jimlawless-cfg.so``
+ * ``$GOPATH/pkg/linux_amd64_dynlink/libgit.kingpenguin.tk-chteufleur-go-xmpp.git-src-xmpp.so``
+
+And the binary file here :
+ * ``$GOPATH/bin/HTTPAuthentificationOverXMPP.git``
+
+An example can be found [here](https://github.com/jbuberel/buildmodeshared/tree/master/gofromgo).
+
+## Configuration
+
+At the installation, the folder ``$XDG_CONFIG_DIRS/http-auth/`` need to be created (example ``/etc/xdg/http-auth``) where to place the configuration file named ``httpAuth.conf`` and the file lang configuration named ``messages.lang``.
