+# 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.
+
+# How to pull latest Bridges code to the `bridges` subtree
+(in practice)
+
+The `bridges` repo has a stabilized branch `polkadot-v.1.0.0-audited` dedicated for releasing
+and based on Polkadot v1.0.0 code.
+
+```
+cd <polkadot-bulletin-chain-git-repo-dir>
+
+# needs to be done only once
+git remote add -f bridges https://github.com/paritytech/parity-bridges-common.git
+
+# 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,
+git fetch bridges --prune
+git subtree pull --prefix=bridges bridges polkadot-v.1.0.0-audited --squash
+
+# if the command above fails with the "Can't squash-merge: 'bridges' was never added" or
+# "fatal: refusing to merge unrelated histories" error, use this:
+# git merge -s subtree -Xsubtree="bridges" bridges/polkadot-v.1.0.0-audited --allow-unrelated-histories --squash
+
+# so, after fetch and before solving conflicts just run patch,
+# this will remove unneeded files and checks if subtree modules compiles
+#
+# if it fails to build, you'll need to resolve conflicts manually
+./bridges/scripts/verify-pallets-build.sh --ignore-git-state --no-revert
+
+# if there are conflicts, this could help,
+# this removes locally deleted files at least (move changes to git stash for commit)
+git status -s | awk '$1 == "DU" || $1 == "D" || $1 == "MD" || $1 == "AD" {print $2}' | grep "^bridges/" | xargs git rm -q --ignore-unmatch
+
+# (optional) when conflicts resolved, you can check build again - should pass
+# also important: this updates global Cargo.lock
+git commit --amend -S -m "updating bridges subtree + remove extra folders"
+
+# 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
