 # Code Activator
 ##### *A `zsh` utility for terminal-based project navigation*
+[![Generic badge](https://img.shields.io/badge/junegunn-fzf-blueviolet.svg)](https://github.com/junegunn/fzf)
+
+The `CODE_ACTIVATOR` function facilitates terminal-based project navigation by providing an interactive, fuzzy-search CLI.
+
+Generally, the CLI will activate a project's virtual environment then step into the project root.
+Once inside a project, the CLI gives the option to deactivate and return to the user's home directory.
+
+Projects can also be quickly cloned or created from scratch by using the `clone` and `new` operations respectively.
+
+Use the plugin one of three ways:
+1. Use the shortcut combination (`CTRL+SPACE` by default)
+1. Use the alias (`lkj` by default)
+1. Call `CODE_ACTIVATOR` directly (meant for use as an API)
+
+## Installation
+1. install [junegunn/fzf](https://github.com/junegunn/fzf)
+1. clone this repo, and source the `*.plugin.zsh` in your `zshrc`:
+```shell
+# replace <path-to>/code-activator with the appropriate path
+git clone https://github.com/w0ryn/code-activator-zsh.git <path-to>/code-activator
+echo 'source <path-to>/code-activator' >> $HOME/.zshrc
+```
+
+## Configuration
+All configuration options are determined by their respective environment variables.
+
+### Basic Configuration
+Environment Variable               | Default                         | Description
+---------------------------------- | ------------------------------- | -----------
+`CODE_ACTIVATOR__SHORTCUT`         | `^@` (a.k.a. CTRL+SPACE)        | shortcut for running `CODE_ACTIVATOR` as a plugin
+`CODE_ACTIVATOR__DISABLE_SHORTCUT` | `0` (a.k.a. false)              | whether (or not) the shortcut runner is disabled
+`CODE_ACTIVATOR__ALIAS`            | `lkj`                           | easy-to-type alias for running `CODE_ACTIVATOR`
+`CODE_ACTIVATOR__DISABLE_ALIAS`    | `0` (a.k.a. false)              | whether (or not) the alias runner is disabled
+
+### Project Directories
+- `CODE_ACTIVATOR__DIRS` (list) environment variable
+
+A list of fully-qualified paths to project parent directories.
+Provides `($HOME/Code)` as a generic default, but allows for meaningful project grouping:
+```shell
+export CODE_ACTIVATOR__DIRS=(
+	"$HOME/Company/Team1"
+	"$HOME/Company/Team2"
+	"$HOME/Miscellaneous"
+	"$HOME/Personal"
+)
+```
+
+### Known Targets
+- `CODE_ACTIVATOR__KNOWN_TARGETS` (list) environment variable
+- expects targets to end in `:` or `/` character
+- *appends environment variable list to the default list*
+
+A list of default completion targets for setting up or cloning new repositories.
+Includes HTTP and GIT protocol targets for GitHub and BitBucket by default, but you may want to add your user to the list:
+```shell
+export CODE_ACTIVATOR__KNOWN_TARGETS=(
+	'git@github.com:<your-username>/'
+)
+```
