-Fuchsia Open Source Template Repository
-=======================================
+# fargo
-This repository is a template that we will use when creating new open source
-repositories for Fuchsia.
+Fargo is a prototype Fuchsia-specific wrapper around Cargo.
+
+ USAGE:
+ fargo [FLAGS] [SUBCOMMAND]
+
+ FLAGS:
+ -h, --help Prints help information
+ -V, --version Prints version information
+ -v Print verbose output while performing commands
+
+ SUBCOMMANDS:
+ build Build binary targeting Fuchsia device or emulator
+ build-tests Build for Fuchsia device or emulator
+ help Prints this message or the help of the given subcommand(s)
+ restart Stop all Fuchsia emulators and start a new one
+ run Run binary on Fuchsia device or emulator
+ ssh Open a shell on Fuchsia device or emulator
+ start Start a Fuchsia emulator
+ stop Stop all Fuchsia emulators
+ test Run unit tests on Fuchsia device or emulator
+
+The `fargo-test` directory contains something one can use to test-drive.
+
+__At the moment fargo requires the FUCHSIA\_ROOT environmental variable be set to the path to a Fuchsia build.__ The goal is to transition
+fargo to using something like an SDK instead.
+
+Currently fargo does not support building artifacts that need additional libraries.
+
+## To Do
+
+* ~~Clean up build/build-test~~
+* ~~Add support for release builds~~
+* Add support for depending on the FIDL generated crates.
+* Add support for crates like cairo-rs that need native libraries.
