-eiger-detector
-=========
+# eiger-detector
 
-Data Acquisition from the Eiger detector.
+Data acquisition framework for the Eiger detector consisting of:
 
-eigerfan: a fan-out of the Eiger zeromq push/pull stream.
+- eigerfan: a fan-out of the Eiger zeromq push/pull stream
+- EigerMetaWriter: A plugin for the odin-data meta_writer application
+- EigerProcessPlugin: A plugin for the odin-data FrameProcessor
+- EigerFrameDecoder: A plugin for the odin-data FrameReceiver
 
-metalistener: A python application that listens for odin-data meta messages and writes data to a meta file
+# Development
 
-EigerProcessPlugin: Plugin for the odin-data FrameProcessor
+A devcontainer is provided for simpler local development. To get started:
 
-EigerFrameDecoder: Plugin for the odin-data FrameReceiver
+1. Open the project in VSCode and re-open in devcontainer when prompted, or
+   open manually with `Dev Containers: Reopen in Container`
+2. Add odin-data to with `Workspaces: Add Folder to Workspace...`
+3. Build both odin-data and then eiger-detector by selecting a file in each project and:
+    i. `CMake: Delete Cache and Reconfigure`
+    ii. `CMake: Install`
+4. Install the python dependencies
+    i. `pip install -e ./odin-data/python[meta_writer]`
+    ii. `pip install -e ./eiger-detector/python`
+5. Run the dev deployment from the `deploy` directory with `zellij -l startAll.kdl`
 
+It is then possible to edit the python applications and restart, or edit the C++
+applications, rebuild and restart.
+
+To run the tickit simulation, add tickit-devices to the workspace, pip install, and then
+run the `Eiger` launch config.
+
+To run the IOC, add eiger-fastcs to the workspace, pip install and run the `Eiger IOC`
+launch config, which talks to the tickit sim by default. The generated output.bob can
+then be opened in Phoebus for GUI control.
+
+Currently in development is odin-fastcs, which creates an EPICS IOC to control the odin
+processes. To run this, add odin-fastcs to the workspace, pip install, and then run the
+`Odin IOC` launch config, which by default talks to a control server at 127.0.0.1:8888.
+At the time of writing, this will not produce any PVs, but at the time of following this
+guide it may be functional.
