+# 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, caste, color, 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
+coc@geopjr.dev.
+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.

+
+## What is BLÅHAJ?
+
+Apart from [a cute cuddly shark plushie from IKEA](https://www.ikea.com/us/en/p/blahaj-soft-toy-shark-90373590/), BLÅHAJ is a lolcat-like CLI tool that colorizes your input, shows flags and prints colorful sharks!
+
+It has a wide variety of flags/colors to choose from and many options from flag size to whether to colorize by line, word or character.
+
+#
+
+## Installation
+
+### Pre-built
+
+You can download one of the statically-linked pre-built binaries from the [releases page](https://github.com/GeopJr/BLAHAJ/releases/latest).
+
+They are built & published by our lovely [actions](https://github.com/GeopJr/BLAHAJ/actions/workflows/release.yml).
+
+### Building
+
+#### Dependencies
+
+- `crystal` - `1.4.1`
+
+#### Makefile
+
+- `$ make` (or `$ make static` on Alpine Linux for a static build)
+- `# make install`
+
+#
+
+## FAQ
+
+### Why are only striped flags allowed?
+
+Flags with eg. triangles, circles or symbols, need enough horizontal space to determine where and how to display them. BLÅHAJ can't know in advance how long the input is going to be.
+
+### Why are the stripes repeating instead of showing the flag in full?
+
+Just like the previous question, BLÅHAJ can't know how long the text is going to be (vertically) as it colorizes the input as it comes in.
+
+### I would like to add a color scheme or flag
+
+Great! Follow the [Contributing section](#contributing) and modify [data/colors.json](./data/colors.json).
+
+```json
+{
+  "flag/color scheme name": [
+    "color",
+    "per",
+    "stripe"
+  ],
+  "alias for scheme (if any)": "flag/color scheme name"
+}
+```
+
+#
+
+## Examples
+
+```
+$ blahaj -h
+
+BLÅHAJ v1.0.0
+
+Usage:
+    blahaj [arguments]
+    blahaj [arguments] file
+    command | blahaj [arguments]
+
+Examples:
+    blahaj -f trans ~/.bashrc
+    blahaj -s -b
+    neofetch | blahaj -f gay
+    blahaj -f lesbian -m 4
+    blahaj -- -w /etc/os-release
+
+Arguments:
+    -b, --background                 Color the background
+    -f, --flag                       Return a flag
+    -s, --shark                      Shork
+    -i, --individual                 Color individual characters
+    -w, --words                      Color individual words
+    -m MULTIPLIER, --multiplier=MULTIPLIER
+                                     Multiplier for the flag size (-f)
+    -c FLAG, --colors=FLAG           Color scheme to use (Default: trans)
+    --flags                          List all available flags
+    -h, --help                       Show this help
+```
+
+### Shark (`-s`), flag (`-f`), flag with 2x multiplier (`-f -m 2`)
+
+![A screenshot of a terminal with the output of the command "blahaj -s -c pride && blahaj -f -c pan && blahaj -f -c aro -m 2". The output first shows a big ascii shark, colorized in the usual rainbow color scheme of the pride flag (red, orange, yellow, green, blue, purple) repeating (one color per line). Under it, a small pansexual flag (pink, yellow, light blue) and under it a big (2x) aromantic flag (green, light green, white, grey, black).](https://i.imgur.com/SPsIcam.png)
+
+### Pipe, individual characters instead of rows (`-i`)
+
+![A screenshot of a terminal with the output of the command "cowsay "1312" | blahaj -c gay -i". The output shows some ascii art produced by the "cowsay" command of a cow with a speech bubble of the text "1312". The whole cow ascii art is colored per character using the gay / nwlnw flag colors (Dark mix of blue and green, normal mix of blue and green, light mix of blue and green, white, light blueish-purple, normal blueish-purple, dark blueish-purple).](https://i.imgur.com/M3N82H3.png)
+
+### Read from file, background instead of foreground (`-b`), individual words instead of rows (`-w`)
+
+> Notice how the foreground color changes based on the background color.
+
+![A screenshot of a terminal with the output of the command "blahaj -b -c lesbian ./src/blahaj.cr". The output shows some example code of a crystal-lang http server (you can read it and more on https://crystal-lang.org/) with each word's background colored using the colors of the lesbian flag (Dark orange, orange, light orange, white, light pinkish-purple, pinkish-purple, dark pinkish-purple). The foreground color is white on the darker background colors and black on the rest.](https://i.imgur.com/v1mTUmm.png)
+
+### Pipe, default color scheme
+
+![A screenshot of a terminal with the output of the command "echo -e "A\nHAT\nIN\nTIME\nUWU" | blahaj". The output shows the words "A HAT IN TIME UWU" (one per line) colored in the trans flag colors (light blue, light pink, white, light pink, light blue).](https://i.imgur.com/GjY5xP1.png)
