+# Using Parity Bridges Common dependency (`git subtree`).
+
+In `./bridges` sub-directory you can find a `git subtree` imported version of:
+[parity-bridges-common](https://github.com/paritytech/parity-bridges-common/) repository.
+
+(For regular Cumulus contributor 1. is relevant) \
+(For Cumulus maintainer 1. and 2. are relevant) \
+(For Bridges team 1. and 2. and 3. are relevant)
+
+# 1. How to fix broken Bridges code?
+
+To fix Bridges code simply create a commit in current (`Cumulus`) repo. Best if
+the commit is isolated to changes in `./bridges` sub-directory, because it makes
+it easier to import that change back to upstream repo.
+
+(Any changes to `bridges` subtree require Bridges team approve and they should manage backport to Bridges repo)
+
+
+# 2. How to pull latest Bridges code to the `bridges` subtree
+(in practice)
+```
+cd <cumulus-git-repo-dir>
+
+# this will update new git branches from bridges repo
+# there could be unresolved conflicts, but dont worry,
+# lots of them are caused because of removed unneeded files with patch step,
+./scripts/bridges_update_subtree.sh fetch
+
+# so, after fetch and before solving conflicts just run patch,
+# this will remove unneeded files and checks if subtree modules compiles
+./scripts/bridges_update_subtree.sh patch
+
+# if there are conflicts, this could help,
+# this removes locally deleted files at least (move changes to git stash for commit)
+./scripts/bridges_update_subtree.sh merge
+
+# (optional) when conflicts resolved, you can check build again - should pass
+# also important: this updates global Cargo.lock
+./scripts/bridges_update_subtree.sh patch
+
+# add changes to the commit, first command `fetch` starts merge,
+# so after all conflicts are solved and patch passes and compiles,
+# then we need to finish merge with:
+git merge --continue
+````
+
+# 3. How to pull latest Bridges code or contribute back?
+(in theory)
+
+Note that it's totally fine to ping the **Bridges Team** to do that for you. The point
+of adding the code as `git subtree` is to **reduce maintenance cost** for Cumulus/Polkadot
+developers.
+
+If you still would like to either update the code to match latest code from the repo
+or create an upstream PR read below. The following commands should be run in the
+current (`polkadot`) repo.
+
+1. Add Bridges repo as a local remote:
+```
+$ git remote add -f bridges git@github.com:paritytech/parity-bridges-common.git
+```
+
+If you plan to contribute back, consider forking the repository on Github and adding
+your personal fork as a remote as well.
+```
+$ git remote add -f my-bridges git@github.com:tomusdrw/parity-bridges-common.git
+```
+
+2. To update Bridges:
+```
+$ git fetch bridges master
+$ git subtree pull --prefix=bridges bridges master --squash
+````
+
+We use `--squash` to avoid adding individual commits and rather squashing them
+all into one.
+
+3. Clean unneeded files here:
+```
+./bridges/scripts/verify-pallets-build.sh --ignore-git-state --no-revert
+```
+
+4. Contributing back to Bridges (creating upstream PR)
+```
+$ git subtree push --prefix=bridges my-bridges master
+```
+This command will push changes to your personal fork of Bridges repo, from where
+you can simply create a PR to the main repo.
