+# Contributing to ahriman
+
+Welcome to ahriman! The goal of the project is to provide the best user experience to manage Archlinux repositories. In order to follow this we set some limitations for the issue creations and heavily restricted code contribution.
+
+## Create an issue
+
+Basically just follow the suggested templates:
+
+* Bug report requires at least the way to reproduce the issue and behaviour description (expected and actual ones). In order to resolve the bug, the additional questions may be asked, please consider them as lesser evil.
+* Feature requests basically just require feature description and the purpose why do you want this feature to be implemented. It is required to make sure that the feature you want is going to be implemented in the way you really want it (and to make sure that this feature is not already implemented).
+* Questions and discussions have free templates, and you are free to ask your question in the way you want.
+
+## Code contribution
+
+There are some strict limitation for suggested pull requests:
+
+* `autopep8`, `bandit`, `pylint`, `mypy` must pass.
+* Test coverage must remain 100%.
+
+### Code formatting
+
+In order to resolve all difficult cases the `autopep8` is used. You can perform formatting at any time by running `make check` or running `autopep8` command directly.
+
+### Code style
+
+Again, the most checks can be performed by `make check` command, though some additional guidelines must be applied:
+
+* Every class, every function (including private and protected), every attribute must be documented. The project follows [Google style documentation](https://google.github.io/styleguide/pyguide.html). The only exception is local functions.
+* For any path interactions `pathlib.Path` must be used.
+* Configuration interactions must go through `ahriman.core.configuration.Configuration` class instance.
+* In case if class load requires some actions, it is recommended to create class method which can be used for class instantiating.
+* The code must follow the exception safety, unless it is explicitly asked by end user. It means that most exceptions must be handled and printed to log, no other actions must be done (e.g. raising another exception).
+* For the external command `ahriman.core.util.check_output` function must be used.
+* Every temporary file/directory must be removed at the end of processing, no matter what. The ``tempfile`` module provides good ways to do it.
+* Import order must be the following:
+
+    ```python
+    # optional imports from future module
+    from __future__ import annotations
+
+    # Module import for those which are installed into environment (no matter standard library or not)...
+    import os
+    # ...one per line...
+    import pyalpm
+    # ...in alphabetical order
+    import sys
+
+    # Blank line between
+    # ``from module import submodule`` import
+    from pathlib import Path
+    # ...again in alphabet order. It is possible to do several imports, but make sure that they are also in alphabetical order.
+    from pyalpm import Handle, Package
+
+    # Blank line again and package imports
+    from ahriman.core.configuration import Configuration
+    ```
+
+* One file should define only one class, exception is class satellites in case if file length remain less than 200 lines.
+* It is possible to create file which contains some functions (e.g. `ahriman.core.util`), but in this case you would need to define `__all__` attribute.
+* The file size mentioned above must be applicable in general. In case of big classes consider splitting them into traits.
+* No global variable allowed outside of `ahriman.version` module.
+* Single quotes are not allowed. The reason behind this restriction is the fact that docstrings must be written by using double quotes only, and we would like to make style consistent.
+* If your class writes anything to log, the `ahriman.core.lazy_logging.LazyLogging` trait must be used.
+
+### Other checks
+
+The projects also uses typing checks (provided by `mypy`) and some linter checks provided by `pylint` and `bandit`. Those checks must be passed successfully for any open pull requests.

+Triggers are extensions which can be used in order to perform any actions on application start, after the update process and, finally, before the application exit. The package provides two default extensions - one is report generation and another one is remote upload feature.
 
 The main idea is to load classes by their full path (e.g. ``ahriman.core.upload.UploadTrigger``) by using ``importlib``: get the last part of the import and treat it as class name, join remain part by ``.`` and interpret as module path, import module and extract attribute from it.
 
 The loaded triggers will be called with ``ahriman.models.result.Result`` and ``List[Packages]`` arguments, which describes the process result and current repository packages respectively. Any exception raised will be suppressed and will generate an exception message in logs.
 
+In addition triggers can implement ``on_start`` and ``on_stop`` actions which will be called on the application start and right before the application exit. The ``on_start`` action is usually being called from handlers directly in order to make sure that no trigger will be run when it is not required (e.g. on user management). As soon as ``on_start`` action is called, the additional flag will be set; ``ahriman.core.triggers.TriggerLoader`` class implements ``__del__`` method in which, if the flag is set, the ``on_stop`` actions will be called.

+The package provides ability to write custom extensions which will be run on (the most) actions, e.g. after updates. By default ahriman provides three types of extensions - reporting, files uploading and PKGBUILD syncronization. Each extension must derive from the ``ahriman.core.triggers.Trigger`` class and should implement at least one of the abstract methods:
+
+* ``on_result`` - trigger action which will be called after build process, the build result and the list of repository packages will be supplied as arguments.
+* ``on_start`` - trigger action which will be called right before the start of the application process.
+* ``on_stop`` - action which will be called right before the exit.
+
+Note, it isn't required to implement all of those methods (or even one of them), however, it is highly recommended to avoid trigger actions in ``__init__`` method as it will be run on any application start (e.g. even if you are just searching in AUR).
+
+Built-in triggers
+-----------------
+
+For the configuration details and settings explanation kindly refer to the :doc:`documentation <configuration>`.
+
+``ahriman.core.gitremote.RemotePullTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This trigger will be called before any action (``on_start``) and pulls remote PKGBUILD repository locally; after that it copies found PKGBUILDs from the cloned repository to the local cache. It is useful in case if you have patched PGKBUILDs (or even missing in AUR) which you would like to use for package building and, technically, just simplifies the local package building.
+
+In order to update those packages you would need to clone your repository separately, make changes in PKGBUILD (e.g. bump version and update checksums), commit them and push back. On the next ahriman's repository update, it will pull changes you commited and will perform package update.
+
+``ahriman.core.gitremote.RemotePushTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This trigger will be called right after build process (``on_result``). It will pick PKGBUILDs for the updated packages, pull them (together with any other files) and commit and push changes to remote repository. No real use cases, but the most of user repositories do it.
+
+``ahriman.core.report.ReportTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Trigger which can be used for reporting. It implements ``on_result`` method and thus being called on each build update and generates report (e.g. html, telegram etc) according to the current settings.
+
+``ahriman.core.upload.UploadTrigger``
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This trigger takes build result (``on_result``) and performs syncing of the local packages to the remote mirror (e.g. S3 or just by rsync).
