 Yarn Berry plugin to update dependencies.
 
+## Usage
+
+```sh
+yarn semver up --config semver-up.json
+```
+
+Define a `semver-up.json` config file like so:
+
+```json
+{
+    "rules": [
+        ["@babel/*", {
+            "maxPackageUpdates": false,
+            "preserveSemVerRange": true
+        }]
+    ],
+    "maxRulesApplied": 1
+}
+```
+
+"rules" takes an array of tuples of the form `[Package Name Glob, Config]`. You can set a default rule group via a wildcard like so:
+
+```json
+{
+    "rules": [
+        ["@babel/*", {
+            "preserveSemVerRange": false
+        }],
+        ["*", {
+            "preserveSemVerRange": true
+        }],
+    ],
+    "maxRulesApplied": 1
+}
+```
+
+The rules are ordered by precedence. The first rule that matches is used when grouping packages.
+
+If you set `maxPackageUpdates` for a group, you can limit the number of packages within that group that are allowed to be updated. It defaults to "false" which means no limit.
+
+If you set `maxRulesApplied`, you can limit how many groups to update. It defaults to `1` with the idea that we want to keep pull requests constrainted to related dependencies. You can disable it by setting `maxRulesApplied` to false, thus removing the limit.
+
+You can use dry run mode to not commit changes to the package.jsons.
+
+```sh
+yarn semver up --config semver-up.json --dry-run
+```
