+# Installation
+
+Git clone this repository, and `cd` into directory for remaining commands
+```
+git clone https://github.com/openai/gpt-2.git && cd gpt-2
+```
+
+Then, follow instructions for either native or Docker installation.
+
+## Native Installation
+
+All steps can optionally be done in a virtual environment using tools such as `virtualenv` or `conda`.
+
+Install tensorflow 1.12 (with GPU support, if you have a GPU and want everything to run faster)
+```
+pip3 install tensorflow==1.12.0
+```
+or
+```
+pip3 install tensorflow-gpu==1.12.0
+```
+
+Install other python packages:
+```
+pip3 install -r requirements.txt
+```
+
+Download the model data
+```
+python3 download_model.py 117M
+```
+
+## Docker Installation
+
+Build the Dockerfile and tag the created image as `gpt-2`:
+```
+docker build --tag gpt-2 -f Dockerfile.gpu . # or Dockerfile.cpu
+```
+
+Start an interactive bash session from the `gpt-2` docker image.
+
+You can opt to use the `--runtime=nvidia` flag if you have access to a NVIDIA GPU
+and a valid install of [nvidia-docker 2.0](https://github.com/nvidia/nvidia-docker/wiki/Installation-(version-2.0)).
+```
+docker run --runtime=nvidia -it gpt-2 bash
+```

+
+Some of the examples below may include Unicode text characters. Set the environment variable:
+```
+export PYTHONIOENCODING=UTF-8
+```
+to override the standard stream settings in UTF-8 mode.
+
+## Unconditional sample generation
+
+To generate unconditional samples from the small model:
+```
+python3 src/generate_unconditional_samples.py | tee /tmp/samples
+```
+There are various flags for controlling the samples:
+```
+python3 src/generate_unconditional_samples.py --top_k 40 --temperature 0.7 | tee /tmp/samples
+```
+
+To check flag descriptions, use:
+```
+python3 src/generate_unconditional_samples.py -- --help
+```
+
+## Conditional sample generation
+
+To give the model custom prompts, you can use:
+```
+python3 src/interactive_conditional_samples.py --top_k 40
+```
+
+To check flag descriptions, use:
+```
+python3 src/interactive_conditional_samples.py -- --help
+```
