+# Skylib Maintainer's Guide
+
+## The Parts of Skylib
+
+*   `bzl_library.bzl` - used by almost all rule sets, and thus requiring
+    especial attention to maintaining backwards compatibility. Ideally, it ought
+    to be moved out of Skylib and and into Bazel's bundled `@bazel_tools` repo
+    (see https://github.com/bazelbuild/bazel-skylib/issues/127).
+*   Test libraries - `rules/analysis_test.bzl`, `rules/build_test.bzl`,
+    `lib/unittest.bzl`; these are under more active development than the rest of
+    Skylib, because we want to provide rule authors with a good testing story.
+    Ideally, these ought to be moved out of Skylib and evolved at a faster pace.
+*   A kitchen sink of utility modules (everything else). Formerly, these
+    features were piled on in a rather haphazard manner. For any new additions,
+    we want to be more conservative: add a feature only if it is widely needed
+    (or was already independently implemented in multiple rule sets), if the
+    interface is unimpeachable, if level of abstraction is not shallow, and the
+    implementation is efficient.
+
+## PR Review Standards
+
+Because Skylib is so widely used, breaking backwards compatibility can cause
+widespread pain, and shouldn't be done lightly. Therefore:
+
+1.  In the first place, avoid adding insufficiently thought out, insufficiently
+    tested features which will later need to be replaced in a
+    backwards-incompatible manner. See the criteria in README.md.
+2.  Given a choice between breaking backwards compatibilty and keeping it, try
+    to keep backwards compatibility. For example, if adding a new argument to a
+    function, add it to the end of the argument list, so that existing callers'
+    positional arguments continue to work.
+3.  Keep Skylib out-of-the-box compatible with the current stable Bazel release
+    (ideally - with two most recent stable releases).
+    *   For example, when adding a new function which calls the new
+        `native.foobar()` method which was introduced in the latest Bazel
+        pre-release or is gated behind an `--incompatible` flag, use an `if
+        hasattr(native, "foobar")` check to keep the rest of your module (which
+        doesn't need `native.foobar()`) working even when `native.foobar()` is
+        not available.
+
+In addition, make sure that new code is documented and tested.
+
+If a PR adds or changes any docstrings, check that Markdown docs in `docs`
+directory are updated; if not, ask the PR author to run
+`./docs/regenerate_docs.sh`. (See
+https://github.com/bazelbuild/bazel-skylib/pull/321 for the proposal to automate
+this.)
+
+## Making a New Release
+
+1.  Update CHANGELOG.md at the top. You may want to use the following template:
+
+--------------------------------------------------------------------------------
+
+Release $VERSION
+
+**New Features**
+
+-   Feature
+-   Feature
+
+**Incompatible Changes**
+
+-   Change
+-   Change
+
+**Contributors**
+
+Name 1, Name 2, Name 3 (alphabetically from `git log`)
+
+--------------------------------------------------------------------------------
+
+2.  Bump `version` in version.bzl to the new version.
+3.  Ensure that the commits for steps 1 and 2 have been merged. All further
+    steps must be performed on a single, known-good git commit.
+4.  `bazel build //distribution:bazel-skylib-$VERSION.tar.gz`
+5.  Copy the `bazel-skylib-$VERSION.tar.gz` tarball to the mirror (you'll need
+    Bazel developer gcloud credentials; assuming you are a Bazel developer, you
+    can obtain them via `gcloud init`):
+
+```
+gsutil cp bazel-bin/distro/bazel-skylib-$VERSION.tar.gz gs://bazel-mirror/github.com/bazelbuild/bazel-skylib/releases/download/$VERSION/bazel-skylib-$VERSION.tar.gz
+gsutil setmeta -h "Cache-Control: public, max-age=31536000" "gs://bazel-mirror/github.com/bazelbuild/bazel-skylib/releases/download/$VERSION/bazel-skylib-$VERSION.tar.gz"
+```
+
+6.  Run `sha256sum bazel-bin/distro/bazel-skylib-$VERSION.tar.gz`; you'll need
+    the checksum for the release notes.
+7.  Draft a new release with a new tag named $VERSION in github. Attach
+    `bazel-skylib-$VERSION.tar.gz` to the release. For the release notes, use
+    the CHANGELOG.md entry plus the following template:
+
+--------------------------------------------------------------------------------
+
+**WORKSPACE setup**
+
+```
+load("@bazel_tools//tools/build_defs/repo:http.bzl", "http_archive")
+http_archive(
+    name = "bazel_skylib",
+    urls = [
+        "https://mirror.bazel.build/github.com/bazelbuild/bazel-skylib/releases/download/$VERSION/bazel-skylib-$VERSION.tar.gz",
+        "https://github.com/bazelbuild/bazel-skylib/releases/download/$VERSION/bazel-skylib-$VERSION.tar.gz",
+    ],
+    sha256 = "$SHA256SUM",
+)
+load("@bazel_skylib//:workspace.bzl", "bazel_skylib_workspace")
+bazel_skylib_workspace()
+```
+
+**Using the rules**
+
+See [the source](https://github.com/bazelbuild/bazel-skylib/tree/$VERSION).
