+# Alpine Dockerfile
+
+## About
+
+This dockerfile is based on [ruimarinho/docker-bitcoin-core](https://github.com/ruimarinho/docker-bitcoin-core/blob/master/0.17/alpine/Dockerfile) however its made to work for raspberry pi installs, and also has wallet disabled. This also builds on x86_64 environment too.
+
+I've also removed the entrypoint has that has some issues, and replaced it to work without.
+
+
+## Need a bitcoin config file?
+
+Use one of my [scripts](https://gitlab.com/nolim1t/financial-independence/tree/master/contrib/lightningd-config-generator) or [scripts(1)](https://github.com/lncm/dockerfiles/tree/master/contrib/lightningd-config-generator) which generates a bitcoin.conf and matching lightning conf.
+
+
+## Invocation
+
+```bash
+# Install dependencies (Alpine)
+apk add pwgen
+apk add curl
+apk add bash
