Streamline Talawa-Docs Content

[palisadoes]

The Talawa Docs content is vague in these areas:

1. Getting started with Outreachy
2. The rationale for the technologies we use
3. Explications of the Palisadoes Foundation main focus areas
4. Introductions to our repositories
5. Overviews of our architecture.

We need to improve this to make sure we have a better user experience when reading our documentation site.
