+
+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement by opening an
+issue or contacting one or more of the project maintainers.
+
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+
+429 Too Many Requests
+---------------------
+
+Instaloader has a logic to keep track of its requests to Instagram and to obey
+their rate limits. The rate controller assumes that
+
+- at one time, Instaloader is the only application that consumes requests, i.e.
+  neither the Instagram browser interface, nor a mobile app, nor another
+  Instaloader instance is running in parallel, and
+
+- no requests had been consumed when Instaloader starts.
+
+The latter one implies that restarting or reinstantiating Instaloader often
+within short time is prone to cause a 429.
+
+Since the behavior of the rate controller might change between different
+versions of Instaloader, make sure to use the current version of Instaloader,
+especially when encountering many 429 errors.
+
+If a request is denied with a 429,
+Instaloader retries the request as soon as the temporary ban is assumed to be
+expired. In case the retry continuously fails for some reason, which should not
+happen under normal conditions, consider adjusting the
+:option:`--max-connection-attempts` option.
+
+There have been observations that services, that in their nature offer
+promiscuous IP addresses, such as cloud, VPN and public proxy services, might be
+subject to significantly stricter limits for anonymous access. However,
+logged-in accesses (see :option:`--login`) do not seem to be affected.
+
+Instaloader allows to adjust the rate controlling behavior by overriding
+:class:`instaloader.RateController`.
+
+Too many queries in the last time
+---------------------------------
+
+**"Too many queries in the last time"** is not an error. It is a notice that the
+rate limit has almost been reached, according to Instaloader's own rate
+accounting mechanism.
+
+Instaloader allows to adjust the rate controlling behavior by overriding
+:class:`instaloader.RateController`.
+
+Private but not followed
+------------------------
+
+You have to follow a private account to access most of its associated
+information.
+
+Login error
+-----------
+
+Instaloader's login *should* work fine, both with and without
+Two-Factor-Authentication. It also supports handling the *checkpoint challenge*,
+issued when Instagram suspects authentication activity on your account, by
+pointing the user to an URL to be opened in a browser.
+
+Nevertheless, in :issue:`92` and :issue:`615` users reported problems with
+logging in. We recommend to always keep the session file which Instaloader
+creates when using :option:`--login`. If a session file is present,
+:option:`--login` does not make use of the failure-prone login procedure.
+Also, session files usually do not expire.
+
+If you do not have a session file present, you may use the following script
+(:example:`615_import_firefox_session.py`) to workaround login problems by
+importing the session cookies from Firefox and bypassing Instaloader's login and
+so still use Instaloader's logged-in functionality.
+
+.. literalinclude:: codesnippets/615_import_firefox_session.py
+
+To use this script,
+
+#. Download the script: :example:`615_import_firefox_session.py`,
+
+#. Login to Instagram in Firefox,
+
+#. Execute the snippet, e.g. with ``python 615_import_firefox_session.py``,
+
+#. Then, ``instaloader -l USERNAME`` should work fine.
+
+This script also supports specifying a cookie file path, which may be useful if
+you use multiple Firefox profiles or if your operating system has the directory
+structure differently set up. Also, you can specify an alternative session file
+path.
