 ## Quick Start

@ -66,35 +68,21 @@ Note: You'll also see a second link: `http://localhost:8000/___graphql`. This is

 Open the `blog` directory in your code editor of choice and edit `src/templates/index-template.js`. Save your changes and the browser will update in real time!

-## Deploy with Netlify
-
-[Netlify](https://netlify.com) CMS can run in any frontend web environment, but the quickest way to try it out is by running it on a pre-configured starter site with Netlify. Use the button below to build and deploy your own copy of the repository:
-
-<a href="https://app.netlify.com/start/deploy?repository=https://github.com/alxshelepenok/gatsby-starter-lumen" target="_blank"><img src="https://www.netlify.com/img/deploy/button.svg" alt="Deploy to Netlify"></a>
-
-After clicking that button, you’ll authenticate with GitHub and choose a repository name. Netlify will then automatically create a repository in your GitHub account with a copy of the files from the template. Next, it will build and deploy the new site on Netlify, bringing you to the site dashboard when the build is complete. Next, you’ll need to set up Netlify’s Identity service to authorize users to log in to the CMS.
-
-## Deploy to Github Pages
-
-To deploy to github pages, simply do the following:
-
- Ensure that your `package.json` file correctly reflects where this repo lives
- Change the `pathPrefix` in your `config.js`
- Run the standard deploy command
-
 ```sh
 yarn deploy
 ```

-
 #### Access Locally
+
 ```
 $ git clone https://github.com/[GITHUB_USERNAME]/[REPO_NAME].git
 $ cd [REPO_NAME]
 $ yarn
 $ yarn develop
 ```
+
 To test the CMS locally, you'll need run a production build of the site:
+
 ```
 $ yarn build
 $ gatsby serve

 In January 1465, Gutenberg's achievements were recognized and he was given the title Hofmann (gentleman of the court) by von Nassau. This honor included a stipend, an annual court outfit, as well as 2,180 litres of grain and 2,000 litres of wine tax-free. It is believed he may have moved back to Mainz around this time, but this is not certain.

 Gutenberg's technique of making movable type remains unclear. In the following decades, punches and copper matrices became standardized in the rapidly disseminating printing presses across Europe. Whether Gutenberg used this sophisticated technique or a somewhat primitive version has been the subject of considerable debate.

 Typography is not about typefaces. It’s not about what looks best, it’s about what feels right. What communicates the message best. Typography, in its essence, is about the message. “Typographical design should perform optically what the speaker creates through voice and gesture of his thoughts.”, as El Lissitzky, a famous Russian typographer, put it.

 We lost a part of ourselves because of this chase after perfection. We forgot about the craftsmanship along the way. And the worst part is that we don’t care. The transition to the digital age made that clear. We choose typefaces like clueless zombies. There’s no meaning in our work. Type sizes, leading, margins… It’s all just a few clicks or lines of code. The message isn’t important anymore. There’s no more “why” behind the “what”.

 Human beings aren’t perfect. Perfection is something that will always elude us. There will always be a small part of humanity in everything we do. No matter how small that part, we should make sure that it transcends the limits of the medium. We have to think about the message first. What typeface should we use and why? Does the typeface match the message and what we want to communicate with it? What will be the leading and why? Will there be more typefaces in our design? On what ground will they be combined? What makes our design unique and why? This is the part of humanity that is left in typography. It might be the last part. Are we really going to give it up?
