+# `ngx_http_voms_module` for developers
+
+A devcontainer is ready to use for the developers. A set of packages without nginx are already installed.
+
+## How to build and install nginx with or without httpg patch
+
+To build and install the latest stable version of [nginx](http://nginx.org/en/download.html) you have to copy the `nginx.repo` file (it is contained in the `docker` directory) into the `/etc/yum.repos.d/` directory and install nginx with `yum`:
+
+```shell
+$ sudo cp docker/nginx.repo /etc/yum.repos.d/
+$ sudo yum install -y nginx
+```
+
+Otherwise, if you want to build and install the latest stable version of [nginx](http://nginx.org/en/download.html) with the httpg patch, a bash library is ready to use. You can source it and follow the commands below:
+
+```shell
+$ source .devcontainer/assets/build-library.sh
+$ downloadNginx
+$ buildHttpgNginxRPM
+$ sudo rpm -ivh ~/rpmbuild/RPMS/x86_64/nginx-*.httpg.x86_64.rpm
+```
+
+## How to build and install the `ngx_http_voms_module`
+
+If you want to build and install the `ngx_http_voms_module`, nginx have to be installed in the container (see the previous section). When this requirement is satisfied, you can use the library contained in the `.devcontainer/assets` folder as follows (NOTE: if you have already download nginx source file, you can skip the relative command):
+
+```shell
+$ source .devcontainer/assets/build-library.sh
+$ downloadNginx
+$ buildVomsModuleRPM
+$ sudo rpm -ivh ~/rpmbuild/RPMS/x86_64/nginx-module-http-voms-*.x86_64.rpm
+```
+## How to manage this project
+
+If you want to understand how this project works, start from the CI. Three stages are defined:
+
+### 1. build-rpms
+
+Starting from a clear AlmaLinux 9, we install all the useful packages to compile nginx and to build a rpm package. The bash steps that achieves these results are defined in the `.devcontainer/assets/build-library.sh` file, so you can read that bash script to learn which nginx version we use, how to download it, how to set up the environment and how to build the rpm. 
+
+It is important to underline that to build the nginx rpm we use the spec file in the `rpm` repo, that is the official nginx 1.24.0 spec file increased by the HTTPG patch. To build the `ngx_http_voms_module` we have defined an appropriate spec file indeed. The files that are used to build the rpm module are written, called and collocated following the common practices of the nginx modules: a source file is defined in the `src` folder, the `config` and the `config.make` files are in the root project directory.
+
+At the end of this stage, all the useful rpms are saved as job artifacts.
+
+### 2. docker-build-rpms
+
+In this stage we set up a docker image with nginx, the httpg patch and the `ngx_http_voms_module`. To do this, we use a set of scripts in the [`helper-scripts`](https://baltig.infn.it/mw-devel/helper-scripts.git) project.
+
+The dockerfile and all the files needed for its compilation are in the `docker` directory. The image starts from AlmaLinux 9, defines a user and installs a set of useful packages. After that we import the nginx repo file, in this way we can download a lot of packages provided by nginx, including its last stable version. In the end we install the rpm packages that we build in the previous stage and the njs module.
+
+### 3. push-to-dockerhub
+
+In this last stage we push on dockerhub the image that we have builded in the previous stage. Note that this stage is run only when we push something in the master branch.

 ## Description
 
-_ngx_http_voms_module_ is a module for the [NGINX web server](https://www.nginx.org/) that enables client-side authentication based on X.509 proxies augmented with Attribute Certificates, typically obtained through a [Virtual Organization Membership Service](https://italiangrid.github.io/voms/) (VOMS).
+`ngx_http_voms_module` is a module for the [Nginx web server](https://www.nginx.org/) that enables client-side authentication based on X.509 proxy certificates augmented with VOMS Attribute Certificates, typically obtained from a [Virtual Organization Membership Service](https://italiangrid.github.io/voms/) (VOMS) server.
 
-## Installation
+The module defines a set of *embedded* variables, whose values are extracted from the first Attribute Certificate found in the certificate chain.
 
-The generic installation instructions are:
+### Embedded Variables
+
+The module makes the following embedded variables available for use in an Nginx configuration file:
+
+#### voms_user
+
+The Subject of the End-Entity certificate, used to sign the proxy.
+
+_Example_: ``/C=IT/O=IGI/CN=test0``
+
+#### ssl_client_ee_s_dn
+
+Like `voms_user`, the Subject of the End-Entity certificate. Unlike `voms_user`, it is available even for non-VOMS proxies and is formatted according to RFC 2253.
+
+_Example_: `CN=test0,O=IGI,C=IT`
+
+#### voms_user_ca
+
+The Issuer (Certificate Authority) of the End-Entity certificate.
+
+_Example_: `/C=IT/O=IGI/CN=Test CA`
+
+#### ssl_client_ee_i_dn
+
+Like `voms_user_ca`, the Issuer of the End-Entity certificate. Unlike `voms_user_ca`, it is available even for non-VOMS proxies and is formatted according to RFC 2253.
+
+_Example_: `CN=Test CA,O=IGI,C=IT`
+
+#### voms_fqans
+
+A comma-separated list of Fully Qualified Attribute Names. See [The VOMS Attribute Certificate Format](http://ogf.org/documents/GFD.182.pdf) for more details.
+
+_Example_: `/test.vo/exp1,/test.vo/exp2,/test.vo/exp3/Role=PIPPO`
+
+#### voms_server
+
+The Subject of the VOMS server certificate, used to sign the Attribute Certificate.
+
+_Example_: `/C=IT/O=IGI/CN=voms.example`
+
+#### voms_server_ca
 
-    $ cd nginx-1.x.y
-    $ ./configure --add-module=/path/to/ngx_http_voms_module
-    $ make && make install
+The Issuer (Certificate Authority) of the VOMS server certificate.
 
-A Docker image is available for use in the context of the StoRM2 project, where the OpenResty distribution is used:
+_Example_: `/C=IT/O=IGI/CN=Test CA`
 
-    $ docker run --rm -it -v /path/to/ngx_http_voms_module:/home/build/ngx_http_voms_module storm2/ngx-voms-build
-    % cd openresty-1.x.y
-    % ./configure ${resty_config_options} --add-module=../ngx_http_voms_module
-    % make && make install
+#### voms_vo
 
-## Variables
+The name of the Virtual Organization (VO) to which the End Entity belongs.
 
-The module makes the following variables available for use in an NGINX configuration file:
+_Example_: `test.vo`
+
+#### voms_server_uri
+
+The hostname and port of the VOMS network service that issued the Attribute Certificate, in the form _hostname_ :_port_.
+
+_Example_: `voms.example:15000`
+
+#### voms_not_before
+
+The date before which the Attribute Certificate is not yet valid, in the form _YYYYMMDDhhmmss_ `Z`.
+
+_Example_: `20180101000000Z`
+
+#### voms_not_after
+
+The date after which the Attribute Certificate is not valid anymore, in the form _YYYYMMDDhhmmss_ `Z`.
+
+_Example_: `20180101120000Z`
+
+#### voms_generic_attributes
+
+A comma-separated list of attributes, each defined by three properties and formatted as `n=`_name_ `v=`_value_ `q=`_qualifier_. The qualifier typically coincides with the name of the VO.
+
+_Example_: `n=nickname v=newland q=test.vo,n=nickname v=giaco q=test.vo`
+
+#### voms_serial
+
+The serial number of the Attribute Certificate in hexadecimal format.
+
+_Example_: `7B`
+
+## Installation
+
+### prerequisites
+The software dependecies are listed in the [provide-deps](docker/library-scripts/provide-deps.sh) script in the `docker` directory.
+
+The nginx source files are also needed. To download them in ```/tmp/nginx-x.y.z``` you can execute:
+
+```shell
+$ ngxVersion=<version>
+$ wget -O /tmp/nginx-$ngxVersion.tar.gz https://nginx.org/download/nginx-$ngxVersion.tar.gz
+$ cd /tmp && tar -xzvf /tmp/nginx-$ngxVersion.tar.gz && cd -
+```
+
+### Generic installation
+The generic installation instructions are:
 
-### voms_fqans
+```shell
+$ cd /tmp/nginx-x.y.z
+$ ./configure --add-module=/path/to/ngx_http_voms_module
+$ make && make install
+```
 
-A comma-separated list of _Fully Qualified Attribute Names_
+### Docker container
 
-### voms_user
+A Docker image with nginx and the `ngx_http_voms_module` is available, you can find it [here](https://hub.docker.com/r/cnafsd/nginx-httpg-voms).
 
+### For the developers
+A [.devcontainer](.devcontainer) is provided for the developers with all the instructions on how to use it, how to build the rpm module and how to install it.
 
 ## Testing
 
-Setup and files to test the *ngx\_http\_voms\_module* are contained in the `t` folder.
