+Documentation
+=============
+
+Sphinx is used to pull richly formatted comments out of code, merge them with hand-written documentation and render it
+in HTML and other formats.
+
+To build the docs, simply run `$ fab -H localhost build_docs` once you have set up Fabric.
+
+Restructured Text (RsT) vs MarkDown (md)
+----------------------------------------
+
+There's much on the internet about this. Suffice to say RsT_ is preferred for Python documentation while md is preferred for web markup or for certain other languages.
+
+.. _Rst: [http://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html]` style is preferred, 
+
+`md` files can also be incorporated by using mdinclude directives in the indices. They are translated to RsT before rendering to the various formats. Headers are translated as a hard-coded level `(H1: =, H2: -, H3: ^, H4: ~, H5: ", H6: #`.  This represents a small consideration for both styles. If markup is not translated to rst well enough, switch to rst.

+Operational Security
+====================
+
+Bitmessage has many features that are designed to protect your anonymity during normal use. There are other things that you must or should do if you value your anonymity.
+
+Castles in the sand
+-------------------
+
+You cannot build a strong castle on unstable foundations. If your operating system is not wholly owned by you then it is impossible to make guarantees about an application.
+
+ * Carefully choose your operating system
+ * Ensure your operating system is up to date
+ * Ensure any dependencies and requirements are up to date
+
+Extrordinary claims require extrordinary evidence
+-------------------------------------------------
+
+If we are to make bold claims about protecting your privacy we should demonstrate this by strong actions.
+
+- PGP signed commits
+- looking to audit
+- warrant canary
+
+Digital foootprint
+------------------
+
+Your internet use can reveal metadata you wouldn't expect. This can be connected with other information about you if you're not careful.
+
+ * Use separate addresses for different puprose
+ * Don't make the same mistakes all the time
+ * Your language use is unique. The more you type, the more you fingerprint yourself. The words you know and use often vs the words you don't know or use often.
+
+Cleaning history
+----------------
+
+ * Tell your browser not to store BitMessage addresses
+ * Microsoft Office seems to offer the ability to define sensitive informations types. If browsers don't already they may in the future. Consider adding `BM-\w{x..y}`.

+Developing 
+==========
+
+Devops tasks
+------------
+
+Bitmessage makes use of fabric_ to define tasks such as building documentation or running checks and tests on the code. If you can install 
+
+.. _fabric: https://fabfile.org
+
+Code style and linters
+----------------------
+
+We aim to be PEP8 compliant but we recognise that we have a long way still to go. Currently we have style and lint exceptions specified at the most specific place we can. We are ignoring certain issues project-wide in order to avoid alert-blindess, avoid style and lint regressions and to allow continuous integration to hook into the output from the tools. While it is hoped that all new changes pass the checks, fixing some existing violations are mini-projects in themselves. Current thinking on ignorable violations is reflected in the options and comments in setup.cfg. Module and line-level lint warnings represent refactoring opportunities.
+
+Pull requests
+-------------
+
+There is a template at PULL_REQUEST_TEMPLATE.md that appears in the pull-request description. Please replace this text with something appropriate to your changes based off the ideas in the template.
+
+Bike-shedding
+-------------
+
+Beyond having well-documented, Pythonic code with static analysis tool checks, extensive test coverage and powerful devops tools, what else can we have? Without violating any linters there is room for making arbirary decisions solely for the sake of project consistency. These are the stuff of the pedant's PR comments. Rather than have such conversations in PR comments, we can lay out the result of discussion here.
+
+I'm putting up a strawman for each topic here, mostly based on my memory of reading related Stack Overflow articles etc. If contributors feel strongly (and we don't have anything better to do) then maybe we can convince each other to update this section.
+
+Trailing vs hanging braces
+   Data
+      Hanging closing brace is preferred, trailing commas always to help reduce churn in diffs
+   Function, class, method args
+      Inline until line-length, then style as per data
+   Nesting
+      Functions
+         Short: group hanging close parentheses 
+         Long: one closing parentheses per line
+
+Single vs double quotes
+   Single quotes are preferred; less strain on the hands, eyes
+
+   Double quotes are only better so as to contain single quotes, but we want to contain doubles as often 
+
+Line continuation
+   Implicit parentheses continuation is preferred
+
+British vs American spelling
+   We should be consistent, it looks like we have American to British at approx 140 to 60 in the code. There's not enough occurrences that we couldn't be consistent one way or the other. It breaks my heart that British spelling could lose this one but I'm happy to 'z' things up for the sake of consistency. So I put forward British to be preferred. Either that strawman wins out, or I incite interest in ~bike-shedding~ guiding the direction of this crucial topic from others.
+
+Dependency graph
+----------------
+
+These images are not very useful right now but the aim is to tweak the settings of one or more of them to be informative, and/or divide them up into smaller grapghs.
+
+To re-build them, run `fab build_docs:dep_graphs=true`. Note that the dot graph takes a lot of time.
+
+.. figure:: ../../../../_static/deps-neato.png

+
+Key management
+--------------
+
+Nitro key
+^^^^^^^^^
+
+Regular contributors are enouraged to take further steps to protect their key and the Nitro Key (Start) is recommended by the BitMessage project for this purpose.
+
+Debian-quirks
+~~~~~~~~~~~~~
+
+Stretch makes use of the directory ~/.gnupg/private-keys-v1.d/ to store the private keys. This simplifies some steps of the Nitro Key instructions. See step 5 of Debian's subkeys_ wiki page

Here you may change that behavior by having Bitmessage give up after a certain number of days or months.&lt;/p&gt;&lt;p&gt;Leave these input fields blank for the default behavior. &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</source>

Możesz podwyższyć tę wartość dla nowo-utworzonych adresów podwyższając wartości tutaj. Każdy nowy adres będzie wymagał przez nadawców wyższej trudności. Jest jeden wyjątek: jeżeli dodasz kolegę do swojej książki adresowej, Bitmessage automatycznie powiadomi go kiedy następnym razem wyślesz do niego wiadomość, że musi tylko wykonać minimalną ilość pracy: trudność 1.</translation>

         <source>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;Bitmessage can utilize a different Bitcoin-based program called Namecoin to make addresses human-friendly. For example, instead of having to tell your friend your long Bitmessage address, you can simply tell him to send a message to &lt;span style=&quot; font-style:italic;&quot;&gt;test. &lt;/span&gt;&lt;/p&gt;&lt;p&gt;(Getting your own Bitmessage address into Namecoin is still rather difficult).&lt;/p&gt;&lt;p&gt;Bitmessage can use either namecoind directly or a running nmcontrol instance.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</source>
         <translation>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;Bitmessage potrafi wykorzystać inny program oparty na Bitcoinie - Namecoin - aby sprawić adresy czytelnymi dla ludzi. Na przykład, zamiast podawać koledze swój długi adres Bitmessage, możesz po prostu powiedzieć mu aby wysłał wiadomość pod &lt;span style=&quot; font-style:italic;&quot;&gt;id/ksywka&lt;/span&gt;.&lt;/p&gt;&lt;p&gt;(Utworzenie swojego adresu Bitmessage w Namecoinie jest ciągle racze trudne).&lt;/p&gt;&lt;p&gt;Bitmessage może skorzystać albo bezpośrednio z namecoind, albo z działającego wątku nmcontrol.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</translation>

         <source>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;By default, if you send a message to someone and he is offline for more than two days, Bitmessage will send the message again after an additional two days. This will be continued with exponential backoff forever; messages will be resent after 5, 10, 20 days ect. until the receiver acknowledges them. Here you may change that behavior by having Bitmessage give up after a certain number of days or months.&lt;/p&gt;&lt;p&gt;Leave these input fields blank for the default behavior. &lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</source>
         <translation>&lt;html&gt;&lt;head/&gt;&lt;body&gt;&lt;p&gt;Domyślnie jeżeli wyślesz wiadomość do kogoś i ta osoba będzie poza siecią przez jakiś czas, Bitmessage spróbuje ponownie wysłać wiadomość trochę później, i potem ponownie. Program będzie próbował wysyłać wiadomość do czasu aż odbiorca potwierdzi odbiór. Tutaj możesz zmienić kiedy Bitmessage ma zaprzestać próby wysyłania.&lt;/p&gt;&lt;p&gt;Pozostaw te poza puste, aby ustawić domyślne zachowanie.&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;</translation>
