# meta-transport-ipfs — a MetaMesh transport plugin for meta-share.

# Build context: this repo. The transport-plugin SDK is pinned by git tag in
# Cargo.toml; to build against an unreleased local SDK pass it as a named
# context and it replaces the tag:
#   docker build --build-context sdk=../meta-feeder-sdk .
