Everytime you run the script `npm run update-readme`, it reads the categories and guides from the above mentioned folders, generate production links for guides and categories and populate the table of content in the readme. This ensures that any future guides and categories will automatically get added to the readme. - [x] Sorting inside the readme matches the actual category and guides sorting on production

The diagram above shows a comparison of URL, URI, and URN.
|
|
|
|
* **URI**
|
|
|
|
URI stands for Uniform Resource Identifier. It identifies a logical or physical resource on the web. URL and URN are subtypes of URI. URL locates a resource, while URN names a resource.
|
|
|
|
A URI is composed of the following parts:
|
|
|
|
```
|
|
scheme:[//authority]path[?query][#fragment]
|
|
```
|
|
|
|
* **URL**
|
|
|
|
URL stands for Uniform Resource Locator, the key concept of HTTP. It is the address of a unique resource on the web. It can be used with other protocols like FTP and JDBC.
|
|
* **URN**
|
|
|
|
URN stands for Uniform Resource Name. It uses the urn scheme. URNs cannot be used to locate a resource. A simple example given in the diagram is composed of a namespace and a namespace-specific string.
