+# NativeLink Bridge (Experimental)
+
+Make sure you are running an instance of Redis or DragonflyDB in your network.
+
+For DragonflyDB inside docker run:
+
+```bash
+docker run \
+  -d --name some-dragonfly \
+  -p 6379:6379 \
+  --ulimit memlock=-1 \
+  docker.dragonflydb.io/dragonflydb/dragonfly
+
+```
+
+For Redis inside docker run:
+
+```bash
+docker run -d --name some-redis \
+  -p 6379:6379 \
+  redis
+```
+
+Set the Redis URL and the NativeLink pub sub channel ENV variables in `.env` as defined in the `.env.example`
+
+
+The Redis URL format: 'redis://alice:[email protected]:6380'
+
+The NativeLink pub sub channel ENV variable should match `experimental_pub_sub_channel` inside `nativelink-config/example/basic_bes.json`.
+
+Make sure you have set also the `key_prefix` in `nativelink-config/example/basic_bes.json`
+
+## You need 4 Components + Redis
+
+### 1. NativeLink
+
+Start an instance of NativeLink with the basic_bes.json inside the `nativelink-config/example/basic_bes.json`.
+
+### 2. NativeLink Web Bridge
+
+Install the dependencies and run the bridge:
+
+```bash
+bun i && bun run index.ts
+```
+
+### 3. NativeLink Web UI
+
+Inside the web/ui directory run:
+
+```bash
+bun i & bun dev
+```
+
+Now you can open http://localhost:4321.
+
+
+### 4. Bazel
+
+Now you can run your Bazel build with NativeLink and see it in real-time going into the web app
+
+Include this in your .bazelrc
+```bash
+bazel clean && bazel build \
+    --remote_cache=grpc://localhost:50051 \
+    --remote_executor=grpc://localhost:50051 \
+    --bes_backend=grpc://localhost:50061 \
+    --bes_results_url=http://localhost:4321/builds \
+    --bes_upload_mode=fully_async \
+    --build_event_publish_all_actions=true \
+    //local-remote-execution/examples:hello_lre
+```
+
+Make sure to use the right IP, if it's not hosted on `localhost`
+
+
+```bash
+bazel build some-target
