 ## Releasing
-Be sure to update the version in `build.gradle` to a version not ending with `-SNAPSHOT`. Then make a subsequent commit
-with a snapshot for the next version. This will prevent old versions from being uploaded and staged in sonatype.
-
-After artifacts are uploaded you'll need to manually release it here:
-
-https://s01.oss.sonatype.org/#stagingRepositories
-
-The steps to release are:
-1. Delete any old artifacts that are staged. The CI build will upload all artifacts here that aren't snapshots
-   (appended with `-SNAPSHOT`) so some may be in here. The release will fail if there are old artifacts because it
-   will refuse to overwrite an existing version.
-   1. Select the staging repository
-   2. Select the "Content" tab in the lower panel
-   3. Traverse the directory structure until you get to where versions are listed. Delete any versions you do not wish
-      to release
-2.  With the repository selected click on "Close" above the main panel. The version will run through a set of
-    validations that could take up to 5-15 minutes. You can follow these by viewing the "Activity" tab in the lower
-    panel. Once successful, you can then click the "Release" button above the upper panel. Note that the release can
-    still fail, for instance, if there are existing artifacts that it will refuse to overwrite.
-
-The version can take a bit of time to show up in the main repository found here:
-
-https://repo1.maven.org/maven2/io/github/scottg489/unified-diff-parser/
-
-It can also be found here I believe immediately:
-
-https://s01.oss.sonatype.org/content/repositories/staging/io/github/scottg489/unified-diff-parser/
+Releases are automatically deployed and publicly available. To release:
+1. Bump `version` in `build.gradle` to a non-snapshot version
+2. Commit and push
+3. Bump version to next patch and append `-SNAPSHOT`
+4. Commit and push
+
+This avoids accidentally forgetting to add `-SNAPSHOT` before subsequent pushes. The build would otherwise fail because
+it would refuse to overwrite the old version.
