+## Summary
+
+A clear and concise description of what the bug is.
+
+### Steps to reproduce
+
+Steps to reproduce the behavior (commands, environment etc).
+
+### Expected behavior
+
+A clear and concise description of what you expected to happen.
+
+### Logs
+
+Add logs to help explain your problem. By default, the application writes logs into `/dev/log` which is usually default systemd journal and can be accessed by `journalctl` command.
+
+You can also attach any additional information which can be helpful, e.g. configuration used by the application (be aware of passwords and other secrets if any); it can be generated by using `ahriman config` command.
+
+It is also sometimes useful to have information about installed packages which can be accessed by `ahriman version` command.

+# Contributing to ahriman
+
+Welcome to ahriman! The goal of the project is to provide the best user experience to manage Arch linux 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 `tox` or running `autopep8` command directly.
+
+### Code style
+
+Again, the most checks can be performed by `tox` 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.
+* Correct way to document function (if a section is empty, e.g. no notes or there are no args, it should be omitted) is the following:

+        brand-new implementation of :class:`BaseClazz`

+        """
+  
+        CLAZZ_ATTRIBUTE: ClassVar[int] = 42
+  
+        def __init__(self, *args: Any, **kwargs: Any) -> None:
+            """
+            Args:

+            """
+            self.instance_attribute = ""
+    ```
+
+  Note missing comment for the `__init__` method, which is the special case.
+
+* Type annotations are the must, even for local functions. For the function argument `self` (for instance methods) and `cls` (for class methods) should not be annotated.
+* For collection types built-in classes must be used if possible (e.g. `dict` instead of `typing.Dict`, `tuple` instead of `typing.Tuple`). In case if built-in type is not available, but `collections.abc` provides interface, it must be used (e.g. `collections.abc.Awaitable` instead of `typing.Awaitable`, `collections.abc.Iterable` instead of `typing.Iterable`). For union classes, the bar operator (`|`) must be used (e.g. `float | int` instead of `typing.Union[float, int]`), which also includes `typing.Optional` (e.g. `str | None` instead of `Optional[str]`).
+* `classmethod` should (almost) always return `Self`. In case of mypy warning (e.g. if there is a branch in which function doesn't return the instance of `cls`) consider using `staticmethod` instead.
+* Class attributes must be decorated as `ClassVar[...]`.
+* Recommended order of function definitions in class:
+
+    ```python
+    class Clazz:
+  
+        def __init__(self) -> None: ...  # replace with `__post_init__` for dataclasses
+
+        @property
+        def property(self) -> Any: ...
+  
+        @cached_property
+        def property_cached(self) -> Any: ...  # cached property has to be treated as normal one
+
+        @classmethod
+        def class_method(cls) -> Self: ...
+
+        @staticmethod
+        def static_method() -> Any: ...
+
+        def __private_method(self) -> Any: ...
+
+        def _protected_method(self) -> Any: ...
+
+        def usual_method(self) -> Any: ...
+
+        def __hash__(self) -> int: ...  # basically any magic (or look-alike) method
+    ```
+  
+  Methods inside one group should be ordered alphabetically, the only exceptions are `__init__` (`__post_init__` for dataclasses), `__new__` and `__del__` methods which should be defined first. For test methods it is recommended to follow the order in which functions are defined. Same idea applies to frontend classes.
+
+  Though, we would like to highlight abstract methods (i.e. ones which raise `NotImplementedError`), we still keep in global order at the moment.
+
+  For the most cases there is custom `pylint` plugin, which performs checks automatically.
+
+* Abstract methods must raise `NotImplementedError` instead of using `abc.abstractmethod`. The reason behind this restriction is the fact that we have class/static abstract methods for those we need to define their attribute first making the code harder to read.
+* 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 most (expected) exceptions must be handled and printed to log, allowing service to continue work. However, fatal and (in some cases) unexpected exceptions may lead to the application termination.
+* Exceptions without parameters should be raised without parentheses, e.g.:
+
+    ```python
+    raise RuntimeError
+    ```
+
+* 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
+    # Multiline import example
+    from ahriman.core.database.operations import (
+        AuthOperations,
+        BuildOperations,
+    )
+    ```
+
+* Imports goes in alphabetical order, no relative imports allowed. Same rule applies to frontend classes.
+* One file should define only one class, exception is class satellites in case if file length remains less than 400 lines. Same rule applies to frontend classes.
+* It is possible to create file which contains some functions (e.g. `ahriman.core.utils`), 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. Note, however, that `pylint` includes comments and docstrings into counter, thus you need to check file size by other tools.
+* No global variable is allowed outside of `ahriman` module. `ahriman.core.context` is also special case.
+* 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.log.LazyLogging` trait must be used.
+* Web API methods must be documented by using `aiohttp_apispec` library. The schema testing mostly should be implemented in related view class tests. Recommended example for documentation (excluding comments):
+
+    ```python
+    from marshmallow import Schema, fields  
+    
+    from ahriman.web.apispec.decorators import apidocs
+    from ahriman.web.schemas import PackageNameSchema, PaginationSchema
+    from ahriman.web.views.base import BaseView
+
+
+    class RequestSchema(Schema):
+
+        field = fields.String(metadata={"description": "Field description", "example": "foo"})
+
+
+    class ResponseSchema(Schema):
+
+        field = fields.String(required=True, metadata={"description": "Field description"})
+
+
+    class Foo(BaseView):
+
+        POST_PERMISSION = ...
+        ROUTES = ...
+
+        @apidocs(
+            tags=["Tag"],
+            summary="Do foo",
+            description="Extended description of the method which does foo",
+            error_400_enabled=True,  # exception raised by this method
+            error_404_description="Repository is unknown",
+            schema=ResponseSchema,  # leave empty if no responses here
+            match_schema=PackageNameSchema,
+            query_schema=PaginationSchema,
+            body_schema=RequestSchema(many=True),
+        )
+        async def post(self) -> None: ...
+    ```
+
+* It is allowed to change web API to add new fields or remove optional ones. However, in case of model changes, new API version must be introduced.
+* On the other hand, it is allowed to change method signatures, however, it is recommended to add new parameters as optional if possible. Deprecated API can be dropped during major release.
+* Enumerations (`Enum` classes) are allowed and recommended. However, it is recommended to use `StrEnum` class if there are from/to string conversions and `IntEnum` otherwise.
+* `Generator` return type is not allowed. Generator functions must return generic `Iterator` object. Documentation should be described as `Yields`, however, because of pylint checks. Unfortunately, `Iterable` return type is not available for generators also, because of specific `contextlib.contextmanager` case.
+
+### 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.
+
+Frontend checks normally are performed by `eslint` (e.g. `npx run eslint`).
+
+## Developers how to
+
+### Run automated checks
+
+```shell
+tox
+```
+
+Must be usually done before any pushes.
+
+### Generate documentation templates
+
+```shell
+tox -e docs
+```
+
+Must be usually done if there are changes in modules structure.
+
+### Create release
+
+```shell
+tox -m release -- major.minor.patch
+```
+
+The command above will generate documentation, tags, etc., and will push them to GitHub. Other things will be handled by GitHub workflows automatically.
+
+### Hotfixes policy
+
+Sometimes it is required to publish hotfix with specific commits, but some features have been already committed, which should not be included to the hotfix. In this case, some manual steps are required:
+
+1. Create new branch from the last stable release (`major.minor.patch`):
+
+    ```shell
+    git checkout -b release/major.minor major.minor.patch
+    ```
+   
+2. Cherry-pick desired commit(s):
+
+    ```shell
+    git cherry-pick <commit-sha>
+    ```
+   
+   Alternatively, make changes to the new branch and commit them.
+
+3. Push newly created branch to remote:
+
+    ```shell
+    git push --set-upstream origin release/major.minor
+    ```
+   
+4. Proceed to release as usual:
+
+    ```shell
+    tox -m release -- major.minor.patch+1
+    ```

+# Security Policy
+
+## Supported Versions
+
+The project follows bleeding edge philosophy, thus only the latest version is supported with the exception for release candidates (i.e. tags which are marked with `rc` suffix).
+
+## Reporting a Vulnerability
+
+In the most cases you can report (suspected) security vulnerabilities directly on github by using ["Security report" template](https://github.com/arcan1s/ahriman/issues/new?assignees=&labels=security&template=02-security-report.md&title=). However, if your report could lead to data leak or break the system we kindly ask you to contact [current maintainer](AUTHORS) directly by email.
