+
+
+## About
+
+kanban-tui is a lightweight, minimalist, terminal-based [Kanban](https://en.wikipedia.org/wiki/Kanban_board) tool built in
+Rust. Keybindings are vim-like, making it pretty fast to navigate and handle
+tasks. Currently it's not that feature-rich, but it provides all the essential
+functionality you need to manage tasks in the classic Kanban way.
+
+It uses [ratatui](https://crates.io/crates/ratatui) for the TUI interface rendering and [rusqlite](https://crates.io/crates/rusqlite) for data
+persistence. Both awesome crates to work with.
+
+
+## Motivation
+
+Decided to make kanban-tui to work on a non-trivial Rust application. I enjoy
+TUIs for their simplicity and efficiency. I don't really plan on using this, as
+I'm an [org](https://orgmode.org/) person myself, but if someone actually decides they like this level
+of minimalism, then I might consider working on it more.

+
+## Building and Installing
+
+To build and install kanban-tui, follow these steps:
+
+-   Install Rust: If you don't have Rust installed, you can get it from [here](https://www.rust-lang.org/tools/install).
+-   Clone this repository, cd into it
+-   Build the project: `cargo build --release`
+-   The built binary can be found in `target/release/kanban-tui`
+-   Optionally, you can move the binary to a directory in your `$PATH` for easier
+    access.
+
+
+## Usage
+
+It is recommended to run `kanban-tui` from the root of your project so it can
+pick up the project's name. This automatically creates a SQLite database there
+named `kanban.db`.
+
+If you prefer a different name for the database file, you can specify the file
+name when running the app, like `kanban-tui todos.kanban` as an example.
+
+Once open, start creating tasks, then move them across columns to track their
+status - from "To Do", through "In Progress", to "Done". All task and navigation
+operations are performed through simple keybindings.
+
+
+## Keybindings
+
+-   Quit: `q`
+-   Navigation: `hjkl`
+-   Move Task: `HJKL`
+-   New Task: `n`
+-   Edit Task: `e`
+-   Cycle Form Fields: `Tab`
+-   Column Top: `g`
+-   Column Bottom: `G`
+
+
+## Potential Future Features
+
+-   Timestamps for tasks (created, moved, completed)
+-   Customizable column (name, amount, etc;)
+-   More project stats (velocity, avg time to complete)
+-   Column visibility toggle (hide "Ideas")
+-   Attach images (using [Kitty Term Image Protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/))
+-   Read from other backends (Trello, Jira, etc;)
+-   Copy task
+-   Reports
+-   Export to other formats

-* About
+* kanban-tui
+** About
+kanban-tui is a lightweight, minimalist, terminal-based [[https://en.wikipedia.org/wiki/Kanban_board][Kanban]] tool built in
+Rust. Keybindings are vim-like, making it pretty fast to navigate and handle
+tasks. Currently it's not that feature-rich, but it provides all the essential
+functionality you need to manage tasks in the classic Kanban way.

-This ia a Rust powered TUI Kanban Board built using the [[https://github.com/fdehau/tui-rs][tui-rs]] library. It has
-vim-friendly keybindings and while not the most featureful experience, it's fast
-and gets the job done. You can save your TODOs in your project's root as either
-a json file or a SQLite database.
+It uses [[https://crates.io/crates/ratatui][ratatui]] for the TUI interface rendering and [[https://crates.io/crates/rusqlite][rusqlite]] for data
+persistence. Both awesome crates to work with.
+** Motivation
+Decided to make kanban-tui to work on a non-trivial Rust application. I enjoy
+TUIs for their simplicity and efficiency. I don't really plan on using this, as
+I'm an [[https://orgmode.org/][org]] person myself, but if someone actually decides they like this level
+of minimalism, then I might consider working on it more.
