+To achieve reproducible dependencies, we use a [Conan lockfile](https://docs.conan.io/2/tutorial/versioning/lockfiles.html).
 
 The `conan.lock` file in the repository contains a "snapshot" of the current dependencies.
 It is implicitly used when running `conan` commands, you don't need to specify it.
 
 You have to update this file every time you add a new dependency or change a revision or version of an existing dependency.
 
-> [!NOTE]
-> Conan uses local cache by default when creating a lockfile.
->
-> To ensure, that lockfile creation works the same way on all developer machines, you should clear the local cache before creating a new lockfile.
-
-To create a new lockfile, run the following commands in the repository root:
-
-```bash
-conan remove '*' --confirm
-rm conan.lock
-# This ensure that xrplf remote is the first to be consulted
-conan remote add --force --index 0 xrplf https://conan.ripplex.io
-conan lock create .
-```
-
-> [!NOTE]
-> If some dependencies are exclusive for some OS, you may need to run the last command for them adding `--profile:all <PROFILE>`.
+To update a lockfile, run from the repository root: `./.github/scripts/conan/regenerate_lockfile.sh`
