You must save your notebook with the naming convention `YYYY-MM-DD-*.ipynb`. Examples of valid filenames are: ```shell 2020-01-28-My-First-Post.ipynb 2012-09-12-how-to-write-a-blog.ipynb ``` If you fail to name your file correctly, `fastpages` will automatically attempt to fix the problem by prepending the last modified date of your notebook. However, it is recommended that you name your files properly yourself for more transparency. See [Writing Blog Posts With Jupyter](https://github.com/fastai/fastpages#writing-blog-posts-with-jupyter) for more details.

- Python: don't have to declare data type before using it in code
-
Java: declare data type before using it in code
-
Runtime vs Ease of Syntax:
- C (fastest runtime)
- Java
- Python (easier syntax)
-
Extra Command: jupyter notebook [notebook_name] to run notebook in browser
-
config.yml - important file for settings on fastpages site
- formatted in key value pairs (ex. images)

Is there anything we use to verify tools we install? Think about versions.
We can type the tool name and then "--version" to verify tools and see which version is installed.
Is there anything we could verify with Anaconda?
We can use the command "conda list" in Anaconda to get a list of packages. We could also do pip list for packages that pip can recognize.
How would you update a repository?
We can use the command: "git pull upstream master"
