+### Presets
+
+As a developer, you can create your own dev preset by making a `CMakeUserPresets.json` file at the root of
+the project:
+
+```json
+{
+  "version": 2,
+  "cmakeMinimumRequired": {
+    "major": 3,
+    "minor": 15,
+    "patch": 0
+  },
+  "configurePresets": [
+    {
+      "name": "dev",
+      "binaryDir": "${sourceDir}/build/dev",
+      "inherits": ["dev-mode", "ci-<os>"],
+      "cacheVariables": {
+        "CMAKE_BUILD_TYPE": "Debug"
+      }
+    }
+  ],
+  "buildPresets": [
+    {
+      "name": "dev",
+      "configurePreset": "dev",
+      "configuration": "Debug"
+    }
+  ],
+  "testPresets": [
+    {
+      "name": "dev",
+      "configurePreset": "dev",
+      "configuration": "Debug",
+      "output": {
+        "outputOnFailure": true
+      }
+    }
+  ]
+}
+```
+Replace `<os>` in the `CmakeUserPresets.json` file with the name of
+the operating system you have (`win64`, `linux` or `darwin`).
