 By default, all libraries except for the HAL and WPILib get built with a default CMake setup. The libraries are built as shared libraries, and include the JNI libraries as well as building the Java JARs.
 
 ## Prerequisites
 
-The most common prerequisite is going to be OpenCV. OpenCV needs to be findable by CMake. On systems like the Jetson, this is installed by default. Otherwise, you will need to build OpenCV from source and install it.
+The jinja2 pip package is needed to generate classes for NT4's pubsub.
 
-In addition, if you want JNI and Java, you will need a JDK of at least version 11 installed. In addition, you need a `JAVA_HOME` environment variable set properly and set to the JDK directory.
+The protobuf library and compiler are needed for protobuf generation. The QuickBuffers protoc-gen package is also required when Java is being built; this can be obtained from https://github.com/HebiRobotics/QuickBuffers/releases/.

+# AprilTag
+
+## Adding new field to AprilTagFields
+
+### Adding field JSON
+
+1. Add a field layout CSV file to `src/main/native/resources/edu/wpi/first/apriltag`
+    1. See docstring in `convert_apriltag_layouts.py` for more
+2. Run `convert_apriltag_layouts.py` in the same directory as this readme to generate the JSON
+3. That script overwrites all generated JSONs, so undo undesired changes if necessary
+4. Update the field dimensions at the bottom of the JSON
+    1. Length should be in meters from alliance wall to alliance wall
+    2. Width should be in meters from inside guardrail plastic to plastic
+
+### Java updates
+
+1. Update `src/main/java/edu/wpi/first/apriltag/AprilTagFields.java`
+    1. Add enum value for new field to `AprilTagFields`
+    2. Update `AprilTagFields.kDefaultField` if necessary
+
+### C++ updates
+
+1. Update `src/main/native/include/frc/apriltag/AprilTagFields.h`
+    1. Add enum value for new field to `AprilTagFields`
+    2. Update `AprilTagFields::kDefaultField` if necessary
+2. Update `src/main/native/cpp/AprilTagFields.cpp`
+    1. Add resource getter prototype like `std::string_view GetResource_2024_crescendo_json()`
+    2. Add case for new field to switch in `LoadAprilTagLayoutField()`
