+## Runtime Flags
+
+There are three runtime flags that you can set which control the behavior of the profiler. Two of the flags relate to how the SDK resolves the profiler binaries and another flag which alters how the underlying profiler is initialized by v8.
+
+<Note>
+These flags are for advanced used cases and setting them is not required in majority of the cases.
+</Note>
+
+- SENTRY_PROFILER_BINARY_PATH
+
+ This flag sets the profiler binary path and bypasses arch, platform and libc checks. It can be useful in some build configurations if you want to override which binary is required at runtime.
+- SENTRY_PROFILER_BINARY_DIR
+
+ Acts similarly as the flag above, however this flag only specifies the directory where the binaries are located and defers to the runtime to resolve the correct binary depending on the arch, platform and libc version.
+
+- SENTRY_PROFILER_LOGGING_MODE
+
+ The default mode of the v8 CpuProfiler is [kEagerLogging](https://v8docs.nodesource.com/node-18.2/d2/dc3/namespacev8.html#a874b4921ddee43bef58d8538e3149374) which enables the profiler even when no profiles are active—this is good because it makes calls to `startProfiling` fast with the tradeoff of constant CPU overhead.
