+This is a port of runcpm to the raspberry pi pico.
+
+It is based on:
+ * [RunCPM](https://github.com/MockbaTheBorg/RunCPM/)
+ * [RunCPM_RPi_Pico](https://github.com/guidol70/RunCPM_RPi_Pico)
+
+It works on a Raspberry Pi Pico (or Pico W). It uses the internal flash
+for storage, and can be mounted as USB storage.
+
+If your Pico is placed on the Pico DV carrier board, you also get a 100x30
+character screen to enjoy your CP/M output on!
+
+First, build for your device. You must
+ * Use the Philhower Pico Core
+ * In the Tools menu, select
+   * A flash size option that includes at least 512kB for filesystem
+   * USB Stack: Adafruit TinyUSB
+
+After it boots the first time, you need to
+ * Format the flash device on your host computer
+ * Create the folder "<DEVICE>/A/0"
+ * Put something useful in that folder, such as [Zork](http://www.retroarchive.org/cpm/games/zork123_80.zip)
+   * Files must respect the "8.3" naming convention (8 letters filename + 3 letters extension) and be all uppercase
+ * Safely eject the drive, then reset the emulator.
+ * Now at the "A0>" prompt you can run "ZORK1".
