 # Contributing To NeMo DFM
+## 🛠️ Setting Up Your Environment
+
+Use the instructions below to setup a dev environment and a dev container
+
+### Building a container
+```bash
+# We recommend you to get the latest commits for Megatron-Bridge and Autmodel
+# The easiest way to do that might be to remove the 3rdparty directly completely before running the following commands
+git submodule update --init --recursive --remote # Get all the 3rd party submodules
+cd 3rdparty/Megatron-Bridge/3rdparty/Megatron-LM # Megatron LM commit might be wrong
+# Get the right megatron commit from here: https://github.com/NVIDIA-NeMo/Megatron-Bridge/tree/main/3rdparty
+git checkout <commit_hash>
+cd ../../../../
+docker build -f docker/Dockerfile.ci -t dfm:latest .
+```
+
+### Run the container
+```bash
+docker run --ipc=host --ulimit memlock=-1 --ulimit stack=67108864 --gpus all $(pwd):/opt/DFM -it dfm:latest bash
+```
+
+### inside the container
+```bash
+# Add DFM to PYTHONPATH
+export PYTHONPATH=$PYTHONPATH:/opt/DFM
+
+# Run a Mock Run:
+```
