+Most of the sphinx requirements are installed from :origin:`setup.py` and the

+
+To be able to do :ref:`sphinx:math-support` without CDNs, the math are rendered
+as images (``sphinx.ext.imgmath`` extension).  If your docs build (``make
+docs``) shows warnings like this::

+
+
+``port`` :
+  Port number of the searx web application if you run it directly using ``python
+  searx/webapp.py``.  Doesn't apply to searx running on Apache or Nginx.
+
+``secret_key`` :
+  Used for cryptography purpose.
+
+``debug`` :
+  Allow a more detailed log if you run searx directly. Display *detailed* error
+  messages in the browser too, so this must be deactivated in production.
+
+``request_timeout`` :
+  Global timeout of the requests made to others engines in seconds. A bigger
+  timeout will allow to wait for answers from slow engines, but in consequence
+  will slow searx reactivity (the result page may take the time specified in the
+  timeout to load)
+
+``base_url`` :
+  The base URL where searx is deployed.  Used to create correct inbound links.
+
+``themes_path`` :
+  Path to where the themes are located.  If you didn't develop anything, leave it
+  blank.
+
+``default_theme`` :
+  Name of the theme you want to use by default on you searx instance.
+
+``useragent_suffix`` :
+  Suffix to the user-agent searx uses to send requests to others engines.  If an
+  engine wish to block you, a contact info here may be useful to avoid that.
+
+``image_proxy`` :
+  Allow your instance of searx of being able to proxy images.  Uses memory space.
+
+``default_locale`` :
+  Aearx interface language.  If blank, the locale is detected by using the
+  browser language.  If it doesn't work, or you are deploying a language
+  specific instance of searx, a locale can be defined using an ISO language
+  code, like ``fr``, ``en``, ``de``.

+.. _requests proxies: http://docs.python-requests.org/en/latest/user/advanced/#proxies
+.. _PR SOCKS support: https://github.com/kennethreitz/requests/pull/478
+
+``outgoing_proxies`` :
+  Define a proxy you wish to use, see `requests proxies`_.  SOCKS proxies are
+  not supported / see `PR SOCKS support`.
+
+``source_ips`` :
+  If you use multiple nework interfaces, define from which IP the requests must
+  be made.
+
+``locales`` :
+  Locales codes and their names.  Available translations of searx interface.

+
+``engine`` :
+  Name of the python file used to handle requests and responses to and from this
+  search engine.
+
+``shortcut`` :
+  Code used to execute bang requests (in this case using ``!bi`` or ``?bi``)
+
+``base_url`` : optional
+  Part of the URL that should be stable accross every request.  Can be useful to
+  use multiple sites using only one engine, or updating the site URL without
+  touching at the code.
+
+``categories`` : optional
+  Define in which categories this engine will be active.  Most of the time, it is
+  defined in the code of the engine, but in a few cases it is useful, like when
+  describing multiple search engine using the same code.
+
+``timeout`` : optional
+  Timeout of the search with the current search engine.  **Be careful, it will
+  modify the global timeout of searx.**
+
+``api_key`` : optional
+  In a few cases, using an API needs the use of a secret key.  How to obtain them
+  is described in the file.
+
+``disabled`` : optional
+  To disable by default the engine, but not deleting it. It will allow the user
+  to manually activate it in the settings.
+
+``language`` : optional
+  If you want to use another language for a specific engine, you can define it
+  by using the full ISO code of language and country, like ``fr_FR``, ``en_US``,
+  ``de_DE``.
+
+``weigth`` : default ``1``
+  Weighting of the results of this engine.
+
+.. note::
+
+   A few more options are possible, but they are pretty specific to some
+   engines, and so won't be described here.

+Makefile Targets
+================
+
+.. _gnu-make: https://www.gnu.org/software/make/manual/make.html#Introduction
+
+.. sidebar:: build environment
+
+   Before looking deeper at the targets, first read about :ref:`makefile setup`
+   and :ref:`make pyenv`.
+
+With the aim to simplify development cycles, started with :pull:`1756` a
+``Makefile`` based boilerplate was added.  If you are not familiar with
+Makefiles, we recommend to read gnu-make_ introduction.
+
+The usage is simple, just type ``make {target-name}`` to *build* a target.
+Calling the ``help`` target gives a first overview::
+
+  $ make help
+    test      - run developer tests
+    docs      - build documentation
+    docs-live - autobuild HTML documentation while editing
+    run       - run developer instance
+    install   - developer install (./local)
+    uninstall - uninstall (./local)
+    gh-pages  - build docs & deploy on gh-pages branch
+    clean     - drop builds and environments

+Setup
+=====
+
+.. _git stash: https://git-scm.com/docs/git-stash
+
+The main setup is done in the :origin:`Makefile`::
+
+  export GIT_URL=https://github.com/asciimoo/searx
+  export SEARX_URL=https://searx.me
+  export DOCS_URL=https://asciimoo.github.io/searx
+
+.. sidebar:: fork & upstream
+
+   Commit changes in your (local) branch, fork or whatever, but do not push them
+   upstream / `git stash`_ is your friend.

+:GIT_URL: Changes this, to point to your searx fork.
+
+:SEARX_URL: Changes this, to point to your searx instance.
+
+:DOCS_URL: If you host your own (branded) documentation, change this URL.
+
+.. _make pyenv:
+
+Python environment
+==================
+
+.. sidebar:: activate environment
+
+   ``source ./local/py3/bin/activate``
+
+With Makefile we do no longer need to build up the virualenv manually (as
+described in the :ref:`devquickstart` guide).  Jump into your git working tree
+and release a ``make pyenv``:
+
+.. code:: sh
+
+   $ cd ~/searx-clone
+   $ make pyenv
+   PYENV     usage: source ./local/py3/bin/activate
+   ...
+
+With target ``pyenv`` a development environment (aka virtualenv) was build up in
+``./local/py3/``.  To make a *developer install* of searx (:origin:`setup.py`)
+into this environment, use make target ``install``:
+
+.. code:: sh
+
+   $ make install
+   PYENV     usage: source ./local/py3/bin/activate
+   PYENV     using virtualenv from ./local/py3
+   PYENV     install .
+
+You have never to think about intermediate targets like ``pyenv`` or
+``install``, the ``Makefile`` chains them as requisites.  Just run your main
+target.
+
+.. sidebar:: drop environment
+
+   To get rid of the existing environment before re-build use :ref:`clean target
+   <make clean>` first.
+
+If you think, something goes wrong with your ./local environment or you change
+the :origin:`setup.py` file (or the requirements listed in
+:origin:`requirements-dev.txt` and :origin:`requirements.txt`), you have to call
+:ref:`make clean`.
+
+
+.. _make run:
+
+``make run``
+============
+
+To get up a running a developer instance simply call ``make run``.  This enables
+*debug* option in :origin:`searx/settings.yml`, starts a ``./searx/webapp.py``
+instance, disables *debug* option again and opens the URL in your favorite WEB
+browser (:man:`xdg-open`):
+
+.. code:: sh
+
+  $ make run
+  PYENV     usage: source ./local/py3/bin/activate
+  PYENV     install .
+  ./local/py3/bin/python ./searx/webapp.py
+  ...
+  INFO:werkzeug: * Running on http://127.0.0.1:8888/ (Press CTRL+C to quit)
+  ...
+
+.. _make clean:
+
+``make clean``
+==============
+
+Drop all intermediate files, all builds, but keep sources untouched.  Includes
+target ``pyclean`` which drops ./local environment.  Before calling ``make
+clean`` stop all processes using :ref:`make pyenv`.
+
+.. code:: sh
+
+   $ make clean
+   CLEAN     pyclean
+   CLEAN     clean
+
+.. _make docs:
+
+``make docs docs-live docs-clean``
+==================================
+
+We describe the usage of the ``doc*`` targets in the :ref:`How to contribute /
+Documentation <contrib docs>` section.  If you want to edit the documentation
+read our :ref:`make docs-live` section.  If you are working in your own brand,
+adjust your :ref:`Makefile setup <makefile setup>`.
+
+
+.. _make gh-pages:
+
+``make gh-pages``
+=================
+
+To deploy on github.io first adjust your :ref:`Makefile setup <makefile
+setup>`.  For any further read :ref:`deploy on github.io`.
+
+.. _make test:
+
+``make test``
+=============
+
+Runs a series of tests: ``test.pep8``, ``test.unit``, ``test.robot`` and does
+additional :ref:`pylint checks <make pylint>`.  You can run tests selective,
+e.g.:
+
+.. code:: sh
+
+  $ make test.pep8 test.unit
+  . ./local/py3/bin/activate; ./manage.sh pep8_check
+  [!] Running pep8 check
+  . ./local/py3/bin/activate; ./manage.sh unit_tests
+  [!] Running unit tests
+
+.. _make pylint:
+
+``make pylint``
+===============
+
+.. _Pylint: https://www.pylint.org/
+
+Before commiting its recommend to do some (more) linting.  Pylint_ is known as
+one of the best source-code, bug and quality checker for the Python programming
+language.  Pylint_ is not yet a quality gate within our searx project (like
+:ref:`test.pep8 <make test>` it is), but Pylint_ can help to improve code
+quality anyway.  The pylint profile we use at searx project is found in
+project's root folder :origin:`.pylintrc`.
+
+Code quality is a ongoing process.  Don't try to fix all messages from Pylint,
+run Pylint and check if your changed lines are bringing up new messages.  If so,
+fix it.  By this, code quality gets incremental better and if there comes the
+day, the linting is balanced out, we might decide to add Pylint as a quality
+gate.
+
+
+``make pybuild``
+================
+
+.. _PyPi: https://pypi.org/
+.. _twine: https://twine.readthedocs.io/en/latest/
+
+Build Python packages in ``./dist/py``.
+
+.. code:: sh

+  running sdist
+  running egg_info
+  ...
+  $ ls  ./dist/py/
+  searx-0.15.0-py3-none-any.whl  searx-0.15.0.tar.gz
+
+To upload packages to PyPi_, there is also a ``upload-pypi`` target.  It needs
+twine_ to be installed.  Since you are not the owner of :pypi:`searx` you will
+never need the latter.

+public (e.g. Tor users and users sharing IPs with many other users).  Caution:
+privacy is also compromised on these sites due to exposure of cleartext traffic
