+# Cartesi Alpine Packages
+
+This repository contains build scripts for packaging Cartesi related software for Alpine.
+
+## Quick start
+
+Packages in this repository are compatible with **Alpine 3.21** on *amd64*, *arm64*, and *riscv64* architectures using the APK package manager.
+Example usage:
+
+```sh
+# Install key to verify signature of repository packages
+wget -qO /etc/apk/keys/cartesi-apk-key.rsa.pub https://edubart.github.io/linux-packages/apk/keys/cartesi-apk-key.rsa.pub
+
+# Add repository
+echo "https://edubart.github.io/linux-packages/apk/stable" >> /etc/apk/repositories
+
+# Update list of available packages
+apk update
+
+# Install cartesi-machine
+apk add cartesi-machine
+
+# Test cartesi-machine
+cartesi-machine
+```
+
+## Guest using Dockerfile
+
+In case you are building a riscv64 guest rootfs with a Dockerfile, it could be installed more simpler, this way:
+
+```Dockerfile
+FROM --platform=linux/riscv64 alpine:latest
+
+# Install guest tools
+ADD --chmod=644 https://edubart.github.io/linux-packages/apk/keys/cartesi-apk-key.rsa.pub /etc/apk/keys/cartesi-apk-key.rsa.pub
+RUN echo "https://edubart.github.io/linux-packages/apk/stable" >> /etc/apk/repositories
+RUN apk update && apk add cartesi-machine-guest-tools
+
+# Remove unneeded packages to shrink image
+RUN apk del --purge apk-tools alpine-release alpine-keys ca-certificates-bundle libc-utils && rm -rf /var/cache/apk /etc/apk
+```
+
+## Developing
+
+If you would like to contribute to a package addition or update, clone first:
+
+```sh
+git clone git@github.com:edubart/linux-packages.git
+cd linux-packages/alpine
+```
+
+You can check for all possible developing make targets with `make help`.
+Make sure you have Docker is installed in your system to run any of them.
+
+### Building packages
+
+You can build all packages with:
+
+```sh
+make all
+```
+
+In the first time this will generate the Docker image, a new key for signing packages, and build all packages
+
+This may take a while (hours) when building packages from scratch.
+When finished the packages will be available in the `../cdn/apk` directory.
+
+### Building a single package
+
+First make sure you have signature key set up and the builder image for the architecture you want to build:
+
+```sh
+make key
+make image TARGET_ARCH=riscv64
+```
+
+Now add or patch the related package build script,
+you can then build it for a specific architecture with:
+
+```sh
+make cartesi-machine-emulator.apk TARGET_ARCH=riscv64
+```
+
+In this case it will build the `cartesi-machine-emulator` package for `riscv64`.
+
+### Testing
+
+You can test installing all built packages with:
+
+```sh
+make test
+```
+
+This will install all packages for all architectures, and run some very basic tests to check if it's working.
+
+### Debugging
+
+Sometimes to develop a new package build script, it's useful to have a shell to test things:
+
+```sh
+make shell TARGET_ARCH=riscv64
+```
