To create a "fastn package", create a `FASTN.ftd` file in any folder. This marks a folder as `fastn` package:

`fastn` support package dependencies. To add a dependency, simply add this to the `FASTN.ftd` file:

Unlike other package managers like pypi, npm and crates, there is no central package repository in `fastn`. Since every `fastn` package is a website, that website acts as the package repository. What this means is when `fastn` sees `fifthtry.github.io/doc-site` as a dependency, it fetches the content of `fifthtry.github.io/doc-site/FASTN.ftd` file which acts as the meta data for the package, and the meta data includes the URL from where the package contents can be downloaded. In our examples we use Github's raw content to fetch the required files from module. `fastn` appends the required file name after the value of `download-base-url`. Let's suppose if the dependency import requires fetching the `index.ftd` module of `fifthtry.github.io/doc-site` package and `fifthtry.github.io/doc-site/FASTN.ftd` contains `https://raw.githubusercontent.com/fifthtry/doc-site/main` as the value for `download-base-url`, then `fastn` tries to fetch it using `https://raw.githubusercontent.com/fifthtry/doc-site/main/index.ftd` http request. If you are not using `Github`, you can store the entire package in some other location and send the prefix of the url from which the modules can be served.
