+
+## Project Structure & Module Organization
+
+- `objdiff-core`: core library with diffing logic and shared components
+- `objdiff-cli`: CLI/TUI with `ratatui`
+- `objdiff-gui`: GUI with `eframe`/`egui`
+- `objdiff-wasm`: WebAssembly bindings
+
+objdiff has three main frontends: GUI, CLI/TUI, and [web](https://github.com/encounter/objdiff-web) (utilizing `objdiff-wasm`).
+
+`objdiff-gui` is the most fully-featured and is the primary target for new features.
+
+`objdiff-cli` has an interactive TUI `diff` mode (powered by `ratatui`) and a non-interactive `report` mode to generate detailed progress reports (e.g. for <https://decomp.dev>).
+
+`objdiff-wasm` is compiled into a [WebAssembly Component](https://component-model.bytecodealliance.org/). The [API](objdiff-wasm/wit/objdiff.wit) is defined using [WIT](https://component-model.bytecodealliance.org/design/wit.html). The web interface is separate, but mirrors the GUI in functionality.
+
+## Build, Test, and Development Commands
+
+Run `cargo build` for a debug build and `cargo build --release` for an optimized build.
+The CLI can be exercised with `cargo run --release --bin objdiff-cli -- --help`.
+
+The WASM build is not included in the workspace by default due to differences in toolchain and target; build it with `npm -C objdiff-wasm run build`. (nightly required)
+In general, do NOT use `--workspace`, as it will include the WASM crate and likely fail. Formatting and linting commands are exempt.
+
+Pre-commit tasks:
+
+- `cargo test` to run the test suite
+- `cargo +nightly fmt --all` to format code (nightly required)
+- `cargo +nightly clippy --all-targets --all-features --workspace -- -D warnings` to lint code (nightly required)
+- `cargo deny check` (`cargo install --locked cargo-deny` if needed) if dependencies change
+
+## Testing Guidelines
+
+Favor focused unit tests adjacent to the code, and integration scenarios in `objdiff-core/tests`.
+Integration tests utilize snapshots with the `insta` crate; run `curl -LsSf https://insta.rs/install.sh | sh` if needed.
+To generate updated snapshots, use `cargo insta test`, review diffs manually, then accept changes with `cargo insta accept` (or simply `mv` to accept specific snapshots).
+
+## Configuration Tips
+
+- `config.schema.json`: JSON schema for the user-facing project config file (`objdiff.json`)
+- `objdiff-core/config-schema.json`: Internal options schema to generate `DiffObjConfig` (see `objdiff-core/config_gen.rs`)
+
+The project configuration (`objdiff.json`) is intended to be generated by the projects' build system. It includes paths to the target (expected) and base (current) object files, along with build commands and file watch patterns. See `README.md` for a summary of key options.

 ## Usage
 
-objdiff works by comparing two relocatable object files (`.o`). The objects are expected to have the same relative path
-from the "target" and "base" directories.
+objdiff compares two relocatable object files (`.o`). Here's how it works:
 
-For example, if the target ("expected") object is located at `build/asm/MetroTRK/mslsupp.o` and the base ("actual")
-object is located at `build/src/MetroTRK/mslsupp.o`, the following configuration would be used:
+1. **Create an `objdiff.json` configuration file** in your project root (or generate it with your build script).  
+  This file lists **all objects in the project** with their target ("expected") and base ("current") paths.
 
-- Target build directory: `build/asm`
-- Base build directory: `build/src`
-- Object: `MetroTRK/mslsupp.o`
+2. **Load the project** in objdiff.
 
-objdiff will then execute the build system from the project directory to build both objects:
+3. **Select an object** from the sidebar to begin diffing.
 
-```sh
-$ make build/asm/MetroTRK/mslsupp.o # Only if "Build target object" is enabled
-$ make build/src/MetroTRK/mslsupp.o
-```
+4. **objdiff automatically:**
+   - Executes the build system to compile the base object (from current source code)
+   - Compares the two objects and displays the differences
+   - Watches for source file changes and rebuilds when detected
 
-The objects will then be compared and the results will be displayed in the UI.
+The configuration file allows complete flexibility in project structure - your build directories can have any layout as long as the paths are specified correctly.
 
-See [Configuration](#configuration) for more information.
+See [Configuration](#configuration) for setup details.

+> [!NOTE]  
+> View [config.schema.json](config.schema.json) for all available options. Below is a summary of the most important options.
 
-`custom_make` _(optional)_: By default, objdiff will use `make` to build the project.  
-If the project uses a different build system (e.g. `ninja`), specify it here.  
-The build command will be `[custom_make] [custom_args] path/to/object.o`.
+#### Build Configuration
 
-`custom_args` _(optional)_: Additional arguments to pass to the build command prior to the object path.
+**`custom_make`** _(optional, default: `"make"`)_  
+If the project uses a different build system (e.g. `ninja`), specify it here. The build command will be `[custom_make] [custom_args] path/to/object.o`.
 
-`build_target`: If true, objdiff will tell the build system to build the target objects before diffing (e.g.
-  `make path/to/target.o`).  
-This is useful if the target objects are not built by default or can change based on project configuration or edits
-to assembly files.

+#### File Watching
 
-> `name` _(optional)_: The name of the object in the UI. If not specified, the object's `path` will be used.
->
-> `target_path`: Path to the "target" or "expected" object from the project root.  
-> This object is the **intended result** of the match.
->
-> `base_path`: Path to the "base" or "actual" object from the project root.  
-> This object is built from the **current source code**.
->
-> `metadata.auto_generated` _(optional)_: Hides the object from the object list, but still includes it in reports.
->
-> `metadata.complete` _(optional)_: Marks the object as "complete" (or "linked") in the object list.  
-> This is useful for marking objects that are fully decompiled. A value of `false` will mark the object as "incomplete".
+**`watch_patterns`** _(optional, default: listed above)_  
+A list of glob patterns to watch for changes ([supported syntax](https://docs.rs/globset/latest/globset/#syntax)). When these files change, objdiff automatically rebuilds and re-compares objects.
+
+**`ignore_patterns`** _(optional, default: listed above)_  
+A list of glob patterns to explicitly ignore when watching for changes ([supported syntax](https://docs.rs/globset/latest/globset/#syntax)).
+
+#### Units (Objects)
+
+**`units`** _(optional)_  
+If specified, objdiff displays a list of objects in the sidebar for easy navigation. Each unit contains:
+
+- **`name`** _(optional)_ - The display name in the UI. Defaults to the object's `path`.
+- **`target_path`** _(optional)_ - Path to the "target" or "expected" object (the **intended result**).
+- **`base_path`** _(optional)_ - Path to the "base" or "current" object (built from **current source code**). Omit if there is no source object yet.
+- **`metadata.auto_generated`** _(optional)_ - Hides the object from the sidebar but includes it in progress reports.
+- **`metadata.complete`** _(optional)_ - Marks the object as "complete" (linked) when `true` or "incomplete" when `false`.

-## Installing `pre-commit`
+## Contributing
 
-When contributing, it's recommended to install `pre-commit` to automatically run the linter and formatter before a commit.

-
-Rust nightly is required for `cargo +nightly fmt` and `cargo +nightly clippy`.

 ```shell
-$ cargo install --locked cargo-deny
-$ rustup toolchain install nightly
-$ uv tool install pre-commit
-$ pre-commit install
+rustup toolchain install nightly  # Required for cargo fmt/clippy
+cargo install --locked cargo-deny # https://github.com/EmbarkStudios/cargo-deny
+uv tool install pre-commit        # https://docs.astral.sh/uv, or use pipx or pip
