+# Mod Developers
+To opt-in a mod for ModUpdater, you must select an update strategy in ```fabric.mod.json```.
+
+## CurseForge
+This update strategy uses the CurseForge API to check for updates.
+
+### ```fabric.mod.json```
+```json
+{
+    "custom": {
+        "modupdater": {
+            "strategy": "curseforge",
+            "projectID": 306612
+        }
+    }
+}

+- Requires Semantic Versioning
+- [Requires ```build.gradle``` modification](#buildgradle-modification)
+
+## GitHub Releases
+This update strategy uses the GitHub Releases API to check for updates.
+
+### ```fabric.mod.json```
+```json
+{
+    "custom": {
+        "modupdater": {
+            "strategy": "github",
+            "owner": "Repository Owner",

+## JSON
+This update strategy uses the specified JSON file to check for updates.

+        "modupdater": {

+        "version": "1.0.0",
+        "downloadUrl": "https://example.com/thing.jar"
+    }
+}
+```
+
+- Does Not Require Semantic Versioning
+- ```build.gradle``` Modification Is Not Required
+
+## ```build.gradle``` Modification
+Multiple update strategies require the Minecraft version to be appended to the end of the JAR version to detect what Minecraft version a JAR supports.
+
+Replace:
+```gradle
+version = project.mod_version
+```
+with:
+```gradle
+version = "${project.mod_version}+${project.minecraft_version}"
+```
+
+If you prefer hyphens you can also use:
+```gradle
+version = "${project.mod_version}-${project.minecraft_version}"
+```
+
+You can also just use the major version of Minecraft instead of the full version (like ```1.16``` instead of ```1.16.1``` or ```20w20a```).
