+The project follows the [GNOME Code of Conduct](https://conduct.gnome.org/).
 
-## Our Pledge
+If you believe that someone is violating the Code of Conduct, or have any other concerns, please contact us via [cartridges-community@kramo.page](mailto:cartridges-community@kramo.page).
-
-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 at
-cartridges-community@kramo.hu.
-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.

+# [game_id].json specification
+#### Version 2.0
+
+Games are saved to disk in the form of [game_id].json files. These files contain all information about a game excluding its cover, which is handled separately.
+
+## Location
+
+The standard location for these files is `/cartridges/games/` under the data directory of the user (`XDG_DATA_HOME` on Linux).
+
+## Contents
+
+The following attributes are saved:
+
+- [added](#added)
+- [executable](#executable)
+- [game_id](#game_id)
+- [source](#source)
+- [hidden](#hidden)
+- [last_played](#last_played)
+- [name](#name)
+- [developer](#developer)
+- [removed](#removed)
+- [blacklisted](#blacklisted)
+- [version](#version)
+
+### added
+
+The date at which the game was added.
+
+Cartridges will set the value for itself. Don't touch it.
+
+Stored as a Unix time stamp.
+
+### executable
+
+The executable to run when launching a game.
+
+If the source has a URL handler, using that is preferred. In that case, the value should be `"xdg-open url://example/url"` for Linux, `"start url://example/url"` for Windows and `"open url://example/url"` for macOS.
+
+Stored as either a string (preferred) or an argument vector to be passed to the shell through [subprocess.Popen](https://docs.python.org/3/library/subprocess.html#popen-constructor).
+
+### game_id
+
+The unique ID of the game, prefixed with [`[source]_`](#source) to avoid clashes.
+
+If the game's source uses a consistent internal ID system, use the ID from there. If not, use a hash function that always returns the same hash for the same game, even if some of its attributes change inside of the source.
+
+Stored as a string.
+
+### source
+
+A unique ID for the source of the game in lowercase, without spaces or underscores.
+
+If a source provides multiple internal sources, these should be separately labeled, but share a common prefix. eg. `heoic_gog`, `heroic_epic`. This is the only place you should use an underscore.
+
+Stored as a string.
+
+### hidden
+
+Whether or not a game is hidden.
+
+If the source provides a way of hiding games, take the value from there. Otherwise it should be set to false by default.
+
+Stored as a boolean.
+
+### last_played
+
+The date at which the game was last launched from Cartridges.
+
+Cartridges will set the value for itself. Don't touch it.
+
+Stored as a Unix time stamp. 0 if the game hasn't been played yet.
+
+### name
+
+The title of the game.
+
+Stored as a string.
+
+### developer
+
+The developer or publisher of the game.
+
+If there are multiple developers or publishers, they should be joined with a comma and a space (`, `) into one string.
+
+This is an optional attribute. If it can't be retrieved from the source, don't touch it.
+
+Stored as a string.
+
+### removed
+
+Whether or not a game has been removed.
+
+Cartridges will set the value for itself. Don't touch it.
+
+Stored as a boolean.
+
+### blacklisted
+
+Whether or not a game is blacklisted. Blacklisting a game means it is going to still be imported, but not displayed to the user.
+
+You should only blacklist a game based on information you pull from the web. This is to ensure that games which you would skip based on information online are still skipped even if the user loses their internet connection. If an entry is broken locally, just skip it.
+
+The only reason to blacklist a game is if you find out that the locally cached entry is not actually a game (eg. Proton) or is otherwise invalid.
+
+Unless the above criteria is met, don't touch the attribute.
+
+Stored as a boolean.
+
+### version
+
+The version number of the [game_id].json specification.
+
+Cartridges will set the value for itself. Don't touch it.
+
+Stored as a number.
