+### Resolving Duplicate Dependencies in `Check deny.toml bans`
+
+Zebra's CI checks for duplicate crate dependencies: multiple dependencies on different versions of the same crate.
+If a developer or dependabot adds a duplicate dependency, the `Check deny.toml bans` CI job will fail.
+
+You can view Zebra's entire dependency tree using `cargo tree`. It can also show the active features on each dependency.
+
+To fix duplicate dependencies, follow these steps until the duplicate dependencies are fixed:
+1. Check for updates to the crates mentioned in the `Check deny.toml bans` logs, and try doing them in the same PR.
+   For an example, see [PR $5009](https://github.com/ZcashFoundation/zebra/pull/5009#issuecomment-1232488943).
+  a. Check for open dependabot PRs, and
+  b. Manually check for updates to those crates on https://crates.io .
+2. If there are still duplicate dependencies, try removing those dependencies by disabling crate features:
+  a. Check for features that Zebra activates in its `Cargo.toml` files, and try turning them off, then
+  b. Try adding `default-features = false` to Zebra's dependencies (see [PR #4082](https://github.com/ZcashFoundation/zebra/pull/4082/files)).
+3. If there are still duplicate dependencies, add an exception to [`deny.toml`](https://github.com/ZcashFoundation/zebra/blob/main/deny.toml):
+  * Prefer exceptions for dependencies that are closer to Zebra in the dependency tree (sometimes this resolves other duplicates as well),
+  * Add exceptions for the earlier version of duplicate dependencies, not the later version, and
+  * Add a comment about why the dependency exception is needed: what was the dependency update that caused it?
+  * For an example, see [PR #4890](https://github.com/ZcashFoundation/zebra/pull/4890/files).
+4. Repeat step 3 until the dependency warnings are fixed. Adding a single exception can resolve multiple warnings.
