+# Learn Piano Chords (LPC)
+
+Are you a musician looking for a more effective way to improve your craft? Maybe
+you're a music teacher looking to create useful exercises to give your students.
+
+Studying music theory can be a fruitful undertaking, but it can often overwhelm
+or bore students. I think that if practicing is enjoyable, students will
+practice more. Practice doesn't make perfect; *perfect* practice makes perfect.
+Learn Piano Chords is a web app that lowers the barrier to practicing and
+internalizing music theory.
+
+## How does it work?
+
+1. Grab a cell phone or a laptop and your instrument.
+2. Open a web browser and visit the Learn Piano Chords app (URL and app
+   forthcoming).
+6. Set the tempo (i.e. pace) at which you would like to practice.
+4. Set the target duration of your session.
+5. Select the key(s) and chord(s) you would like to practice.
+7. LPC will display chords at various rhythmic intervals during your practice
+   session. It is your job to play these chords in time before the next chord
+   appears.
+
+## Highlights
+
+Here are some useful features of LPC:
+- Tempo: Set the rate at which LPC displays chords.
+- Predefined practice sessions: LPC offers users a few practice sessions to get
+  users started. The goal, however, is to teach users to create their own
+  bespoke practice sessions. LPC aims to foster a community of practitioners who
+  curate and share their practice sessions.
+- Whitelist / blacklist: Construct the set of chords you would like to
+  practice. Let's say you only want to practice triads in the keys of F, C, and
+  G. Would you also like to avoid diminished chords? Or maybe you *only* want to
+  practice major-7th chords for *all* keys. LPC supports all of these scenarios
+  and many others. You can save these chord configurations to reuse them at any
+  time. You can also share chord configurations with other LPC users if you find
+  the practice useful.
+- Inversions: Every chord has inversions. For instance, every triad (i.e. chord
+  composed of three notes) has three inversions: root, second, and third
+  positions. LPC acknowledges all of the positions in which chords may appear
+  and helps you study all, some, or none of these inversions.
+- Harmony: LPC understands basic harmony and can sort the chords you would like
+  to train in various harmonious permutations.
+- Chaos-mode: Feeling confident? Throw the classical notions of harmony to the
+  wayside and use LPC in "chaos-mode" where LPC samples randomly from the Circle
+  of Fifths.
+
+## Developing
+
+If you're interested in contributing, the following will create an environment
+in which you can develop:
+
+```shell
+$ nix-shell
+$ elm-live -- src/Main.elm --output=elm.js
