-# Bundles
-
-This directory includes the actors bundles for each release. Each actor bundle is a zstd compressed
-tarfile containing one bundle per network type. These tarfiles are subsequently embedded in the
-lotus binary.
-
-## Updating
-
-To update, run the `./pack.sh` script. For example, the following will pack the [builtin actors release](https://github.com/filecoin-project/builtin-actors/releases) `dev/20220602` into the `v8` tarfile.
-
-```bash
-./pack.sh v8 dev/20220602
-```
-
-This will:
-
-1. Download the actors bundles and pack them into the appropriate tarfile (`$VERSION.tar.zst`).
-2. Run `make bundle-gen` in the top-level directory to regenerate the bundle metadata file for _all_ network versions (all `*.tar.zst` files in this directory).
-
-## Overriding
-
-To build a bundle, but specify a different release/tag for a specific network, append `$network=$alternative_release` on the command line. For example:
-
-```bash
-./pack.sh v8 dev/20220602 mainnet=v8.0.0 calibrationnet=v8.0.0-rc.1
