+# 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 at
+andrew@brunker.net.au.
+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.
+

+# Sessionizer for Wezterm
+
+---
+
+A tmux like sessionizer for Wezterm that was inspired by [ThePrimeagen's tmux-sessionizer](https://github.com/ThePrimeagen/.dotfiles/blob/master/bin/.local/scripts/tmux-sessionizer)
+
+The sessionizer allows for opening of windows/sessions based on the passed in
+directories, as well as fast and intuative switching between active
+workspaces/sessions
+
+## Setup
+
+An example configuration calling the plugin
+
+```lua
+local wezterm = require "wezterm"
+local sessionizer = wezterm.plugin.require("https://github.com/ElCapitanSponge/sessionizer.wezterm")
+
+local config = {}
+
+if wezterm.config_builder then
+    config = wezterm.config_builder()
+end
+
+--INFO: The sessionizer lverages the `LEADER` mod
+config.leader = {
+    key = "a",
+    mods = "CTRL",
+    timeout_milliseconds = 1000
+}
+
+config.keys = {}
+
+-- INFO: The following is the project directories to search
+local projects = {
+    "~/personal",
+    "~/work"
+}
+
+sessionizer.set_projects(projects)
+sessionizer.configure(config)
+
+return config
+```
+
+## USEAGE
+
+To use the sessionizer you have to define and pass through a table of project
+folders, that are the paths to your applicable repositores to leverage for the
+workspaces.
+
+```lua
+local projects = {
+    "~/personal",
+    "~/work"
+}
+```
+
+To display the sessionizer all you have to do is press the key combination of
+`LEADER` + `f`
+
+To display the active windows/sessions all you have to do is press the key
+combination of `LEADER` + `s`
+
+## Change keybinding
+
+To change the keybinding from the default (`LEADER` + `f`):
+
+```lua
+config.keys = {
+    -- ... other bindings
+    {
+        key = "w",
+        mods = "CTRL|ALT",
+        action = sessionizer.switch_workspace()
+    }
+}
+```
