+# How to release
+
+This is for the Rust crate and Node module. For now, the Python module is
+released separately.
+
+<!--
+The release is started by bumping the versions and pushing a new tag. To do this
+automatically, use the `make_release_commit` GitHub action.
+
+When the tag is pushed, GitHub actions will start building the libraries and
+will upload them to a draft release.
+
+While those jobs are running, edit the release notes as needed. For example, 
+bring relevant new features and bugfixes to the top of the notes and the testing
+and CI changes to the bottom.
+
+Once the jobs have finished, the release will be marked as not draft and the
+artifacts will be released to crates.io, NPM, and PyPI.
+
+-->
+
+## Manual process
+
+The manual release process can be completed on a MacOS machine.
+
+### Bump the versions
+
+You can use the script `ci/bump_versions.sh` to bump the versions. It defaults
+to a `patch` bump, but you can also pass `minor` and `major`. Once you have the
+tag created, push it to GitHub.
+
+```shell
+VERSION=$(bash ci/bump_versions.sh)
+git tag v$VERSION
+git push origin v$VERSION
+```
+
+### Build the MacOS release libraries
+
+One-time setup:
+
+```shell
+rustup target add x86_64-apple-darwin aarch64-apple-darwin
+```
+
+To build both x64 and arm64, run `ci/build_macos_artifacts.sh` without any args:
+
+```shell
+bash ci/build_macos_artifacts.sh
+```
+
+### Build the Linux release libraries
+
+To build a Linux library, we need to use docker with a different build script:
+
+```shell
+ARCH=aarch64
+docker run \
+    -v $(pwd):/io -w /io \
+    quay.io/pypa/manylinux2014_$ARCH \
+    bash ci/build_linux_artifacts.sh $ARCH-unknown-linux-gnu
+```
+
+For x64, change `ARCH` to `x86_64`. NOTE: compiling for a different architecture
+than your machine in Docker is very slow. It's best to do this on a machine with
+matching architecture.
+
+
+<!--
+Similar script for musl binaries (not yet working):
+
+```shell
+ARCH=aarch64
+docker run \
+    --user $(id -u) \
+    -v $(pwd):/io -w /io \
+    quay.io/pypa/musllinux_1_1_$ARCH \
+    bash ci/build_linux_artifacts.sh $ARCH-unknown-linux-musl
+```
+
+-->
+
+<!--
+
+For debugging, use these snippets:
+
+```shell
+ARCH=aarch64
+docker run -it \
+    -v $(pwd):/io -w /io \
+    quay.io/pypa/manylinux2014_$ARCH \
+    bash
+```
+
+```shell
+ARCH=aarch64
+docker run -it \
+    -v $(pwd):/io -w /io \
+    quay.io/pypa/musllinux_1_1_$ARCH \
+    bash
+```
+
+Note: musllinux_1_1 is Alpine Linux 3.12
+-->
+
+
+### Build the npm module
+
+To build the typescript and create a release tarball, run:
+
+```shell
+npm ci
+npm tsc
+npm pack
+```
+
+### Release to npm
+
+Assuming you still have `VERSION` set from earlier:
+
+```shell
+pushd node
+npm publish lancedb-vectordb-$VERSION.tgz
+for tarball in ./dist/lancedb-vectordb-*-$VERSION.tgz;
+    do 
+    npm publish $tarball
+done
+popd
+```
+
+### Release to crates.io
+
+```shell
+cargo publish -p vectordb
+cargo publish -p vectordb-node
+```
