+# Contributing to SMAM
+
+Contributions are more than welcome! There are several ways to get involved:
+
+## Bug reporting
+
+If you notice a bug while using SMAM, please open an [issue](https://github.com/babolivier/smam/issues) giving as much info as you can on your use of SMAM (without giving sensitive data, such as your full config file) that could be relevant for fixing this it.
+
+## Translation
+
+Since [v2.0.0](https://github.com/babolivier/smam/tree/v2.0.0), SMAM can be used in different languages depending on its configuration. However, it is still limited to the languages for which it has translations!
+
+If you want to help out by prividing translations in a language you know, you can do so by forking this repo, copying the file at [`locales/en.json`](https://github.com/babolivier/smam/blob/master/locales/en.json) somewhere, and translating the strings (only the ones on the right of the colon (:), the ones on the left with underscores (\_) are identifiers). If you haven't already done it, move and/or rename your file so it is located in the `locales` directory and is named `xx.json`, `xx` being the two-letter code for the language.
+
+Then send us your new translation by opening a [pull request](https://github.com/babolivier/smam/pulls)!
+
+## Code
+
+If you want to fix a bug, implement a cool feature or add some optimisation to SMAM, feel free to open a [pull request](https://github.com/babolivier/smam/pulls)!
+
+However, if you feel like you're up against a huge task, or just doesn't know where to start, don't hesitate to [open an issue](https://github.com/babolivier/smam/issues) so a SMAM contributor can help you out :smile:
+
+## Anything else
+
+The beauty of free software is that everyone can contribute in their own way! If you want to share a contribution that doesn't fit in the cases mentionned above (e.g. improvements on the contribution process, sharing a blog post about SMAM, etc), please [open an issue](https://github.com/babolivier/smam/issues)! It's the best way to get your stuff noticed and to start a conversation about it :grin:

                             Preamble
 
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
 
   The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
+our General Public Licenses are intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
+software for all its users.
 
   When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.

 modification follow.

+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the

   14. Revised Versions of this License.
 
   The Free Software Foundation may publish revised and/or new versions of

 public statement of acceptance of a version permanently authorizes you
 to choose that version for the Program.

-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
 
   You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.

 ## Templating
 
-Each e-mail sent by the form follows a template described in `template.pug` (it's [Pug](pugjs.org/)). If you want to change the way the e-mails you receive are displayed in your mailbox, just edit it! You don't even need to restart the server aftewards :smile:

 The template also features custom fields, iterating over the `custom` object, containing the field's label and user-input value:
 
 }
 ```
 
+The template needs to be named `template.pug`. If no template could be found under this name, SMAM will use a default one, which features both default and custom fields, and should be sufficient for non-advanced usage.

 ## Personnalising
 
 As you might have already seen, the contact form is generated without any form of style except your browser's default one. But that doesn't meen that you have to add an ugly form to your site to receive contact e-mails, as every element has a specific id (beginning with the `form_` prefix), allowing you to use your own style on your contact form.
