# Flatland submission from Windows
If you are working on windows locally there is a few steps you will need to do in order to make your flatland challenge submission work. Here is a step-by-step instruction on how to achieve this.
## Installing WSL
-Enable [WSL](https://docs.microsoft.com/en-us/windows/wsl/install-win10) on Windows.
-Get [Ubuntu](https://www.microsoft.com/en-us/p/ubuntu/9nblggh4msv6?SilentAuth=1&wa=wsignin1.0&activetab=pivot:overviewtab) for Windows.
-Follow the instructions provided in the microsoft documentation.
+
+1. Enable [WSL](https://docs.microsoft.com/en-us/windows/wsl/install-win10) on Windows.
+2. Get [Ubuntu](https://www.microsoft.com/en-us/p/ubuntu/9nblggh4msv6?SilentAuth=1&wa=wsignin1.0&activetab=pivot:overviewtab) for Windows.
+3. Run your **Ubuntu** system on your computer
+4. Now let us install the **Dependencies**. From within the **Ubuntu-Shell** run:
+
+### Dependencies
+
+First download **Anaconda** by running this in the **Ubuntu Shell** if you are on a 64bit machine, otherwise update link.( **ATTENTION:** You need the **Linux** version and not Windows version!!!)
+
+```
+wget https://repo.anaconda.com/archive/Anaconda3-2019.07-Linux-x86_64.sh
+```
+
+Now we can install **Anaconda** for Ubuntu
+
+```
+chmod +x Anaconda3-2019.07-Linux-x86_64.sh
+ ./Anaconda3-2019.07-Linux-x86_64.sh
+```
+
+For all changes to take affect usually you will have to restart Ubuntu, just close the terminal and run Ubuntu again.
+
+### Setup
+* Setup you `ssh` keys for your gitlab account by running. You can install in the default directory and use key without password if you like.
+
+```sh
+ssh-keygen
+```
+
+Now you need to copy your key to your gitlab account. Find the key
+
+```sh
+cd .ssh
+cat id_rsa.pub
+```
+Copy all the output and add it to your [gitlab keys](https://gitlab.aicrowd.com/profile/keys)
+
+* Clone your own repository remeber to use ssh cloning and change to the directory where you would like to clone it to! Enter `yes` when promted. If you don't have an own repository yet, start by cloning the official starter kit
+
+```
+git clone git@gitlab.aicrowd.com:<YOUR_USER_NAME>/flatland-challenge-starter-kit.git
+```
+
+or official starter kit
+
+```
+git clone git@github.com:AIcrowd/flatland-challenge-starter-kit.git
+cd flatland-challenge-starter-kit
+```
+
+* Create a conda environment from the provided `environment.yml`
+
+```sh
+conda env create -f environment.yml
+```
+
+This might take a little bit of time to finish.
+
+* Activate the conda environment and install your code specific dependencies
+
+```sh
+conda activate flatland-rl
+# If say you want to install PyTorch
+# conda install pytorch torchvision -c pytorch
+#
+# or you can even use pip to install any additional packages
+# for example :
+# pip install -U flatland-rl
+# which updates the flatland-rl package to the latest version
+```
+
+# How do I specify my software runtime ?
+
+The software runtime is specified by exporting your `conda` env to the root
+of your repository by doing :
+
+```
+# The included environment.yml is generated by the command below, and you do not need to run it again
+# if you did not add any custom dependencies
+
+conda env export --no-build > environment.yml
+
+# Note the `--no-build` flag, which is important if you want your anaconda env to be replicable across all
+```
+
+This `environment.yml` file will be used to recreate the `conda environment` inside the Docker container.
+This repository includes an example `environment.yml`
+
+You can specify your software environment by using all the [available configuration options of repo2docker](https://repo2docker.readthedocs.io/en/latest/config_files.html). (But please remember to use [aicrowd-repo2docker](https://pypi.org/project/aicrowd-repo2docker/) to have GPU support)
+
+
+# What should my code structure be like ?
+
+Please follow the structure documented in the included [run.py](https://github.com/AIcrowd/flatland-challenge-starter-kit/blob/master/run.py) to adapt
+your already existing code to the required structure for this round.
+
+## Important Concepts
+
+### Repository Structure
+
+- `aicrowd.json`
+ Each repository should have a `aicrowd.json` with the following content :
+
+```json
+{
+ "challenge_id": "aicrowd_flatland_challenge_2019",
+ "grader_id": "aicrowd_flatland_challenge_2019",
+ "authors": ["your-aicrowd-username"],
+ "description": "sample description about your awesome agent",
+ "license": "MIT",
+ "debug": false
+}
+```
+
+If you are not familiar with working in the shell. Use
+
+```sh
+nano aicrowd.json
+```
+
+to edit the JSON file.
+
+This is used to map your submission to the said challenge, so please remember to use the correct `challenge_id` and `grader_id` as specified above.
+
+If you set `debug` to `true`, then the evaluation will run on a separate set of 20 environments, and the logs from your submitted code (if it fails), will be made available to you to help you debug.
+**NOTE** : **IMPORTANT** : By default we have set `debug:false`, so when you have done the basic integration testing of your code, and are ready to make a final submission, please do make sure to set `debug` to `true` in `aicrowd.json`.
+
+### Code Entrypoint
+
+The evaluator will use `/home/aicrowd/run.sh` as the entrypoint, so please remember to have a `run.sh` at the root, which can instantitate any necessary environment variables, and also start executing your actual code. This repository includes a sample `run.sh` file.
+If you are using a Dockerfile to specify your software environment, please remember to create a `aicrowd` user, and place the entrypoint code at `run.sh`.
+If you are unsure what this is all about, you can let `run.sh` be as is, and instead focus on the `run.py` which is being called from within `run.sh`.
+
+## Submission
+
+To make a submission, you will have to create a private repository on [https://gitlab.aicrowd.com/](https://gitlab.aicrowd.com/).
+
+You will have to add your SSH Keys to your GitLab account if you haven't already by following the instructions [here](https://docs.gitlab.com/ee/gitlab-basics/create-your-ssh-keys.html).
+If you do not have SSH Keys, you will first need to [generate one](https://docs.gitlab.com/ee/ssh/README.html#generating-a-new-ssh-key-pair).
+
+Then you can create a submission by making a _tag push_ to your repository on [https://gitlab.aicrowd.com/](https://gitlab.aicrowd.com/).
+**Any tag push (where the tag name begins with "submission-") to your private repository is considered as a submission** . Be sure that all changes where added to the commit before pushing.
+Then you can add the correct git remote, and finally submit by doing :
+
+```
+cd flatland-challenge-starter-kit
+# Add AIcrowd git remote endpoint
+git remote add aicrowd git@gitlab.aicrowd.com/:<YOUR_AICROWD_USER_NAME>/flatland-challenge-starter-kit.git
+git push aicrowd master
+
+# Create a tag for your submission and push
+git tag -am "submission-v0.1" submission-v0.1
+git push aicrowd master
+git push aicrowd submission-v0.1
+
+# Note : If the contents of your repository (latest commit hash) does not change,
+# then pushing a new tag will **not** trigger a new evaluation.
+```
+
+You now should be able to see the details of your submission at :
+[gitlab.aicrowd.com//<YOUR_AICROWD_USER_NAME>/flatland-challenge-starter-kit/issues](gitlab.aicrowd.com//<YOUR_AICROWD_USER_NAME>/flatland-challenge-starter-kit/issues)
+
+**NOTE**: Remember to update your username in the link above :wink:
+
+In the link above, you should start seeing something like this take shape (the whole evaluation can take a bit of time, so please be a bit patient too :wink: ) :
+
+
+**Best of Luck** :tada: :tada:
