-## Obsidian Sample Plugin
+## Scales and Chords
 
-This is a sample plugin for Obsidian (https://obsidian.md).
+This is a plugin to allow you to capture guitar and piano tabs in your Obsidian vault.
 
-This project uses Typescript to provide type checking and documentation.
-The repo depends on the latest plugin API (obsidian.d.ts) in Typescript Definition format, which contains TSDoc comments describing what it does.
+To use this plugin, use a fenced code block like this:
 
-**Note:** The Obsidian API is still in early alpha and is subject to change at any time!
+<pre>
+```tab
+Verse
+G         Am             G/B     G %
+Blackbird singing in the dead of night
+C          C#dim       D    D#dim    Em   D# %
+Take these broken wings and learn to fly
+D   C#dim   C    Cm %
+All your    life
+G/B             A7               D7         G %
+You were only waiting for this moment to arise
+```
+</pre>
 
-This sample plugin demonstrates some of the basic functionality the plugin API can do.
-- Changes the default font color to red using `styles.css`.
-- Adds a ribbon icon, which shows a Notice when clicked.
-- Adds a command "Open Sample Modal" which opens a Modal.
-- Adds a plugin setting tab to the settings page.
-- Registers a global click event and output 'click' to the console.
-- Registers a global interval which logs 'setInterval' to the console.
+The `%` at the end of a line indicates that the line contains chords.  In preview mode, each chord is displayed in bold, and is clickable.  Clicking a chord brings up a modal containing a visual rendition of the chord (as supplied by [ScalesChords](https://www.scales-chords.com/)).
 
-### First time developing plugins?
+Lines that don't end in `%` will be rendered unmodified.
 
-Quick starting guide for new plugin devs:
+In addition, every chord captured by the plugin will be rendered in a big stack below the tab block.  This allows you to open two edit views and keep all the song's chords in view.
 
-- Make a copy of this repo as a template with the "Use this template" button (login to GitHub if you don't see it).
-- Clone your repo to a local development folder. For convenience, you can place this folder in your `.obsidian/plugins/your-plugin-name` folder.
-- Install NodeJS, then run `npm i` in the command line under your repo folder.
-- Run `npm run dev` to compile your plugin from `main.ts` to `main.js`.
-- Make changes to `main.ts` (or create new `.ts` files). Those changes should be automatically compiled into `main.js`.
-- Reload Obsidian to load the new version of your plugin.
-- Enable plugin in settings window.
-- For updates to the Obsidian API run `npm update` in the command line under your repo folder.
+You can change the instrument in the settings.  Just type in one of:
+- `guitar`
+- `piano`
+- `ukelele`
+- `mandolin`
+- `banjo`
 
-### Releasing new releases
+## Caveats
 
-- Update your `manifest.json` with your new version number, such as `1.0.1`, and the minimum Obsidian version required for your latest release.
-- Update your `versions.json` file with `"new-plugin-version": "minimum-obsidian-version"` so older versions of Obsidian can download an older version of your plugin that's compatible.
-- Create new GitHub release using your new version number as the "Tag version". Use the exact version number, don't include a prefix `v`. See here for an example: https://github.com/obsidianmd/obsidian-sample-plugin/releases
-- Upload the files `manifest.json`, `main.js`, `styles.css` as binary attachments.
-- Publish the release.
+- This is my first plugin.
+- I can't play piano or guitar.  I'm learning, and writing a plugin is how I procrastinate practice.
 
-### Adding your plugin to the community plugin list
+Thanks to the fine folks at [ScalesChords](https://www.scales-chords.com/) who provided an API for generating these images!
 
-- Publish an initial version.
-- Make sure you have a `README.md` file in the root of your repo.
-- Make a pull request at https://github.com/obsidianmd/obsidian-releases to add your plugin.
 
-### How to use
-
-- Clone this repo.
-- `npm i` or `yarn` to install dependencies
-- `npm run dev` to start compilation in watch mode.
-
-### Manually installing the plugin
-
-- Copy over `main.js`, `styles.css`, `manifest.json` to your vault `VaultFolder/.obsidian/plugins/your-plugin-id/`.
