 # Life Trinket
 
 A simple life counter for Magic the Gathering written in React JS.
+
+I created this mainly because there was no life counter that I liked on the iOS app store for me and
+my friends when we play Commander.
+
+The outcome is a lightweight web app that does what it needs to do and nothing more. No accounts, no
+ads, minimal tracking ("Games started" and "Back to start" presses for now),
+
+## 📋 Usage
+
+There are some controls that you might now know about, so here's a short list of them.
+
+### Life counter
+
+- **Tap** on a player's + or - button to add or subtract **1 life**.
+- **Long press** on a player's + or - button to add or subtract **10 life**.
+
+### Commander damage and other counters
+
+- **Tap** on the counter to add **1 counter**.
+- **Long press** on the counter to subtract **1 counter**.
+
+### Other
+
+- When a player is **at or below 0 life**, has taken **21 or more Commander Damage** or has **10 or
+  more poison counters**, a button with a skull will appear on that player's card.
+
+  Tap on the button to mark that player as lost, dimming their player card.
+
