 ## Building
 
-Grab tools
+The following instructions should work on the following platforms:
+- Ubuntu 18.04 or higher (x86_64)
+- Docker only
+    - Linux (x86_64, ARM)
+    - macOS (x86_64, ARM)
+
+### Local (Linux)
+
+Works with Ubuntu 18.04 or higher.
+
+#### 1. Install dependencies
+
+```sh
+sudo apt-get update && sudo apt-get install -y $(cat packages.txt)
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+python3 -m pip install -r requirements.txt
+```
+
+#### 2. Grab tools
 
 ```sh
 git submodule update --init --recursive
+cd tools/n64splat
+python3 -m pip install -r requirements.txt
 ```
 
-Drop in `US v1.0` as `baserom.us.v10.z64` (sha1sum: `1fe1632098865f639e22c11b9a81ee8f29c75d7a`)
+#### 3. Add baserom
 
-To extract and build everything
+Add the file for `US v1.0` as `baserom.us.v10.z64` in the project folder.
+
+(optional): Check the baserom checksum
+
+```sh
+sha1sum baserom.us.v10.z64
+```
+
+The output should match the checksum specified above.
+
+#### 4. Build
+
+To extract and build everything simply run:
 
 ```sh
 make
 ```

+If you want to build a specific module, instead do:
+
+```sh
+make <module_id>

-### Prerequisites
+### Local (Docker - Linux/macOS)
 
-Ubuntu 18.04 or higher.
+#### 1. Get the Docker image
+
+(if available) you can pull it from GitLab (but you need to be logged in):
 
 ```sh
-sudo apt-get update && sudo apt-get install -y $(cat packages.txt)
-
-curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
-
-python3 -m pip install -r requirements.txt
+docker login registry.gitlab.com
+docker pull registry.gitlab.com/banjo.decomp/banjo-kazooie:latest
 ```
 
-### Other versions
+(otherwise) you can build it yourself:
+
+```sh
+docker build -t banjo-kazooie .
+```
+
+**NOTE for ARM users** (Windows ARM, Raspberry Pi and similar, or Apple Silicon): Use this command instead:
+
+```sh
+docker build --platform linux/amd64 -t banjo-kazooie .
+```
+
+#### 2. Add baserom
+
+Follow the same instructions as Step 3 above in "Local (Linux)".
+
+#### 3. Run the Docker container
+
+```sh
+docker run -it --rm -v $(pwd):/banjo banjo-kazooie 
+```
+
+**NOTE for ARM users**: Use this command instead:
+
+```sh
+docker run --platform linux/amd64 -it --rm -v $(pwd):/banjo banjo-kazooie 
+```
+
+#### 4. Build
+
+Follow the same instructions as Step 4 above in "Local (Linux)".
+
+To exit Docker, simply type `exit`.
+
+## Other versions
 
 Drop in `us.v11`, `jp`, or `pal` as `baserom.<version>.z64` e.g. `baserom.us.v11.z64`
