+### Opentelemetry Compatibility Issue
+
+**Note**: Status: 31/07/2024, the currently used `opentelemetry-exporter-otlp-proto-http` version `1.25.0` requires
+a `protobuf` version < `5.x.x` and is not compatible with the latest protobuf version `5.27.x`. This is an [open issue](https://github.com/open-telemetry/opentelemetry-python/issues/3958) in opentelemetry, because [support for 4.25.x ends in Q2 '25](https://protobuf.dev/support/version-support/#python). Therefore, we should keep this in mind and update the dependency once opentelemetry includes support for `protobuf 5.27.x`.
+
+
+### Install Protobuf Compiler
+
+**Linux**
+
+1. Download the version of the protobuf compiler matching the protobuf package, currently v4.25.4 so protoc v25.4, from [GitHub](https://github.com/protocolbuffers/protobuf/releases) -> `protobuf-25.4.zip`
+2. Extract the files under `$HOME/.local` or another directory of your choice
+   ```bash
+   unzip protoc-<version>-linux-x86_64.zip -d $HOME/.local
+   ```
+3. Ensure that the `bin` directory is in your `PATH` by adding the following line to your `.bashrc` or `.zshrc`:
+   ```bash
+   export PATH="$PATH:$HOME/.local/bin"
+   ```
+
+**MacOS**
+
+1. Download the version of the protobuf compiler matching the protobuf package, currently v4.25.4 so protoc v25.4, from [GitHub](https://github.com/protocolbuffers/protobuf/releases) -> `protoc-25.4-osx-universal_binary.zip`
+2. Extract the files to a directory of your choice
+3. Copy the executable bin `protoc` to `/usr/local/bin`
+   ```bash
+   sudo cp /Users/you/location-of-unzipped-dir/bin/protoc /usr/local/bin/
+   ```
+4. Open `protoc` in `/usr/local/bin/` via Finder to make it executable, now it should be also on your `PATH`
+
+### Compile Protobuf Files
+
+1. Ensure that the protobuf compiler is installed on your system. You can check this by running:
+   ```bash
+   protoc --version
+   ```
+2. Compile proto files:
+   ```bash
+   protoc --proto_path=./config/proto --python_out=./pyinfra/proto ./config/proto/*.proto
+   ```
+3. Manually adjust import statements in the generated files to match the package structure, e.g.:
+   `import EntryData_pb2 as EntryData__pb2` -> `import pyinfra.proto.EntryData_pb2 as EntryData__pb2`.
+   This does not work automatically because the generated files are not in the same directory as the proto files.
