# Installation Guide
1. Get the code
git clone https://github.com/moov-io/ach
Downloads the entire project code from GitHub to your computer.
cd ach
Moves into the project folder you just downloaded.
2. Docker
Easy RecommendedPrerequisites
- Git Needed to download the project code from GitHub.
- Docker Desktop Needed to build and run containers. Install it and keep it running in the background.
docker pull moov/ach:latest
Type this command into your terminal and run it.
docker run -p 8080:8080 -p 9090:9090 moov/ach:latest
Runs the built image as an actual container.
- [Docker](#docker) ([Config](#configuration-settings))
Type this command into your terminal and run it.
Run docker compose ps to check the containers are Up. If the README mentions a port, open http://localhost:PORT in your browser.
Pulled directly from this repo's README.
3. Go
MediumPrerequisites
go run ./cmd/serverr
Runs the Go program directly without a separate build step.
If the build finishes without errors, it worked. If you used go run ., check the terminal output.
Pulled directly from this repo's README.
4. Make
MediumPrerequisites
- Git Needed to download the project code from GitHub.
- Make Usually pre-installed on Linux/macOS. On Windows, install separately (e.g. via MSYS2 or WSL).
make
Compiles the code based on the generated build configuration to produce an executable.
If it finishes without errors, it worked. Try running the generated executable directly.
