-## 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 compares two relocatable object files (`.o`). Here's how it works:
+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.
 
-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.
+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:
 
-2. **Load the project** in objdiff.
+- Target build directory: `build/asm`
+- Base build directory: `build/src`
+- Object: `MetroTRK/mslsupp.o`
 
-3. **Select an object** from the sidebar to begin diffing.
+objdiff will then execute the build system from the project directory to build both objects:
 
-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
+```sh
+$ make build/asm/MetroTRK/mslsupp.o # Only if "Build target object" is enabled
+$ make build/src/MetroTRK/mslsupp.o
+```
 
-The configuration file allows complete flexibility in project structure - your build directories can have any layout as long as the paths are specified correctly.
+The objects will then be compared and the results will be displayed in the UI.
 
-See [Configuration](#configuration) for setup details.

+View [config.schema.json](config.schema.json) for all available options. The below list is a summary of the most important options.
 
-#### Build Configuration
+`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`.
 
-**`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`.
+`custom_args` _(optional)_: Additional arguments to pass to the build command prior to the object path.
 
-**`custom_args`** _(optional)_  
-Additional arguments to pass to the build command prior to the object path.
+`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.  
+Requires the build system to be configured properly.
 
-**`build_target`**  _(default: `false`)_  
-If true, objdiff will build the target objects before diffing (e.g. `make path/to/target.o`). Useful if target objects are not built by default or can change based on project configuration. Requires proper build system configuration.
+`build_base`: If true, objdiff will tell the build system to build the base objects before diffing (e.g. `make path/to/base.o`).  
+It's unlikely you'll want to disable this, unless you're using an external tool to rebuild the base object on source file changes.
 
-**`build_base`**  _(default: `true`)_  
-If true, objdiff will build the base objects before diffing (e.g. `make path/to/base.o`). It's unlikely you'll want to disable this unless using an external tool to rebuild the base object.
+`watch_patterns` _(optional)_: A list of glob patterns to watch for changes.
+([Supported syntax](https://docs.rs/globset/latest/globset/#syntax))  
+If any of these files change, objdiff will automatically rebuild the objects and re-compare them.  
+If not specified, objdiff will use the default patterns listed above.
 
-#### File Watching
+`units` _(optional)_: If specified, objdiff will display a list of objects in the sidebar for easy navigation.
 
-**`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`.
+> `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".
 
 ## Building
 
 Install Rust via [rustup](https://rustup.rs).
 
 ```shell
-git clone https://github.com/encounter/objdiff.git
-cd objdiff
-cargo run --release
+$ git clone https://github.com/encounter/objdiff.git
+$ cd objdiff
+$ cargo run --release
 ```
 
-Or install directly with cargo:
+Or using `cargo install`.
 
 ```shell
-cargo install --locked --git https://github.com/encounter/objdiff.git objdiff-gui objdiff-cli
+$ cargo install --locked --git https://github.com/encounter/objdiff.git objdiff-gui objdiff-cli
 ```
 
-Binaries will be installed to `~/.cargo/bin` as `objdiff` and `objdiff-cli`.
-
-## Contributing
-
-Install `pre-commit` to run linting and formatting automatically:
-
-```shell
-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
-pre-commit install
-```
+The binaries will be installed to `~/.cargo/bin` as `objdiff` and `objdiff-cli`.
