+
+## Enforcement Responsibilities
+
+Community moderators 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 moderators 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 moderators responsible for enforcement at
+the [Tachiyomi Discord server](https://discord.gg/tachiyomi).
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community moderators are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community moderators 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 moderators, 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.

+- To avoid confusion with the main app:
+    - Change the app name

+    - Change or disable the [app update checker](https://github.com/tachiyomiorg/tachiyomi/blob/master/app/src/main/java/eu/kanade/tachiyomi/data/updater/GithubUpdateChecker.kt)
+- To avoid installation conflicts:
+    - Change the `applicationId` in [`build.gradle.kts`](https://github.com/tachiyomiorg/tachiyomi/blob/master/app/build.gradle.kts)
+- To avoid having your data polluting the main app's analytics and crash report services:
+    - If you want to use Firebase analytics, replace [`google-services.json`](https://github.com/tachiyomiorg/tachiyomi/blob/master/app/src/standard/google-services.json) with your own
+    - If you want to use ACRA crash reporting, replace the `ACRA_URI` endpoint in [`build.gradle.kts`](https://github.com/tachiyomiorg/tachiyomi/blob/master/app/build.gradle.kts) with your own
