feat: Flat import of markdown repo

This is a flat (without history) import of (some of) the content
from our markdown module.

We've imported this without history because the repo contains our
blog posts and showcases posts content prior to porting them to strapi.

Since this contains many images, it would balloon the size of this repo
to import the full history.

Instead, please refer to the history of the (archived) markdown repo

+title: Setting up the FreeSewing development environment
+order: 40
+---
+
+FreeSewing provides a development environment to help you design and develop patterns.
+
+With Node installed, all you need to do to setup this development environment is run this command:
+
+```bash
+npx create-freesewing-pattern
+```
+
+It will take a moment to download some dependencies, and then will ask you the following questions.
+
+You can change all of these later. It's just to get you started.
+If you're not sure what to fill in, you can stick with the defaults or leave them blank.
+Only a few of these are mandatory.
+
+ - **Language**: Use the arrow keys to chose the language of your choice
+ - **Pattern name**: This will be the name of your pattern, but also the name of the folder we'll setup for you. If you're just kicking the tires, something like `test` will do you fine.                      
+ - **description**: A description of your pattern. It's not mandatory.
+ - **Pattern type**: Use the arrow keys to chose either `block` or `pattern`. Choose `pattern` if you're not sure what to pick                   
+ - **department**: Use the arrow keys to pick a department like `menswear`, `womenswear` or `accessories`. This is is only relevant if you decide to publish your pattern later. But by that time you will have learned how to change this.
+ - **Author**: You can enter your name, or leave this blank for now
+ - **GitHub repository**: You can leave this blank for now
+ - **Package manager**: Choose either `npm` or `yarn` as your package manager. If you're not sure, pick `npm`.                    
+
+
+When you've answered all questions, the command will download the development enviroment,
+and set it up based on the choices you made.
+
+This step will take anywhere from a few to about 10 minutes to complete.
+But when it's done, you will have a new folder with the development environent inside.

+Now we will use nvm to install Node JS. Run the following command:
+
+```bash
+nvm install lts/*
+```
+
+This will install the most recent so-called LTS version on your system.
+LTS versions -- short for Long Term Support -- are good node versions
+to use because they are stable and supported for a long time.

+title: Installing nvm
+order: 10
+---
+
+FreeSewing is built with [Node.js](https://nodejs.org/), a JavaScript runtime.
+
+You'll need to install Node JS on your system, and to do so, we'll 
+use [nvm](https://github.com/nvm-sh/nvm), short for _Node version manager_.
+
+Using nvm has a number of benefits in comparison with installing Node from
+the node.js website, or from a package provided by your linux distribution:
+
+ - You can easily switch between different Node versions
+ - Everything gets installed in your home folder, avoiding permission problems
+
+To setup nvm, run the following command in a terminal:
+
+```bash
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash
+```
+
+If you don't have `curl` on your system, here's an alternative approach using `wget`:
+
+```bash
+wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.36.0/install.sh | bash
+```
+
+After the script is completed, try running the following command:
+
+```bash
+nvm
+```
+
+If all goes well, it should show you the nvm help. 
+
+<Tip>
+
+If you get `nvm: command not found` or something similar, close the current terminal
+window, and open a new one. Now `nvm` should be found.

+title: Using a different Node version
+order: 30
+---
+
+Now that you've got Node setup, we can start setting up the FreeSewing
+development environment.
+
+But before doing so, let's look at how `nvm` can help you juggle different
+Node versions.
+
+### nvm ls
+
+To see the different Node versions on your system, run this command:
+
+```bash
+nvm ls
+```
+
+It will show you a list of local node versions. 
+Either the version number, or an _alias_ that points to a specific version.
+You should see the `lts/*` alias in the list which is what we've just installed.
+
+### nvm ls-remote
+
+To see all Node versions that are available, not just those you have locally,
+run this command:
+
+```bash
+nvm ls-remote
+```
+
+Nvm will now spit out a long list of Node versions that you can install.
+
+### nvm install
+
+For any of these versions, either local or remote, you can install them
+by making a note of the version or alias and running this command:
+
+```bash
+nvm install <version-or-alias>
+```
+
+### nvm use
+
+With multiple Node versions installed, `nvm` allows you to switch between different
+versions. Just tell it which version you want to use:
+
+```bash
+nvm use v10.22.1
+```
+
+If you picked a version that is not installed, `nvm` will simply tell you
+and even suggest the command you should type to install it. Handy!

+You will have a new folder that has the name you picked for your pattern.
+If you chose `test`, you will have a `test` folder. If you chose `banana`, you'll have a `banana` folder.
+
+If you enter that folder, you'll find a couple of subfolders:
+
+ - `config` holds your pattern's configuration file
+ - `src` holds your pattern's source code
+ - `example` holds the development environment
+
+To start the development environment, enter the `example` folder and run: `npm run start` (or `yarn start` if you're using Yarn as a package manager.
+
+The development environment will watch for any changes you make to
+the pattern's source code. When you do, it will update automatically in your browser.
