+# Developer Robot
+
+This is a robot project built directly against this repo's sources. It builds the minimum required for deploying to a roboRIO, so it's faster than publishing the whole library to Maven first.
+
+This command builds everything.
+```bash
+./gradlew developerRobot:build
+```
+
+## Simulation
+
+This command runs the C++ subproject on desktop.
+```bash
+./gradlew developerRobot:runCpp
+```
+
+## Deploy to a roboRIO
+
+This project can only deploy over USB. If an alternate IP address is preferred, the `address` block in developerRobot\build.gradle can be changed to point to another address.
+
+This command deploys the C++ project using shared dependencies. Prefer this one for most C++ development.
+```bash
+./gradlew developerRobot:deployShared
+```
+
+This command deploys the C++ project with all dependencies statically linked.
+```bash
+./gradlew developerRobot:deployStatic
+```
+
+This command deploys the Java project and all required dependencies. It also installs the JRE if it's not currently installed.
+```bash
+./gradlew developerRobot:deployJava
+```
+
+Those commands won't start the robot executable, so you have to manually ssh in and start it. The following command will do that.
+```bash
+ssh lvuser@172.22.11.2 frcRunRobot.sh
+```
+
+Console log prints will appear in the terminal.
+
+Deploying any of these to the roboRIO will disable the current startup project until it is redeployed.
