+## Updating libgit2
+
+The following steps can be used to update libgit2:
+
+1. Update the submodule.
+   There are several ways to go about this.
+   One way is to go to the `libgit2-sys/libgit2` directory and run `git fetch origin` to download the latest updates, and then check out a specific tag (such as `git checkout v1.4.1`).
+2. Update all the references to the version:
+    * Update [`libgit2-sys/build.rs`](https://github.com/rust-lang/git2-rs/blob/master/libgit2-sys/build.rs).
+      There is a version probe (search for `cfg.atleast_version`) which should be updated.
+    * Update the version in
+      [`libgit2-sys/Cargo.toml`](https://github.com/rust-lang/git2-rs/blob/master/libgit2-sys/Cargo.toml).
+      Update the metadata portion (the part after the `+`) to match libgit2.
+      Also bump the Cargo version (the part before the `+`), keeping in mind
+      if this will be a SemVer breaking change or not.
+    * Update the dependency version in [`Cargo.toml`](https://github.com/rust-lang/git2-rs/blob/master/Cargo.toml) to match the version in the last step (do not include the `+` metadata).
+      Also update the version of the `git2` crate itself so it will pick up the change to `libgit2-sys` (also keeping in mind if it is a SemVer breaking release).
+    * Update the version in [`README.md`](https://github.com/rust-lang/git2-rs/blob/master/README.md) if needed.
+    * If there was a SemVer-breaking version bump for either library, also update the `html_root_url` attribute in the `lib.rs` of each library.
+3. Run tests.
+   `cargo test -p git2 -p git2-curl` is a good starting point.
+4. Run `systest`.
+   This will validate for any C-level API problems.
+   Unfortunately `systest` does not work on nightly, so you'll need to use stable.
+
+   `cargo +stable run -p systest`
+
+   The changelog at <https://github.com/libgit2/libgit2/blob/main/docs/changelog.md>
+   can be helpful for seeing what has changed.
+   The project has recently started labeling API and ABI breaking changes with labels:
+   <https://github.com/libgit2/libgit2/pulls?q=is%3Apr+label%3A%22api+breaking%22%2C%22abi+breaking%22+is%3Aclosed>
+4. Once you have everything functional, publish a PR with the updates.
