-The Carpentries (https://carpentries.org) curricula is made of of lessons that are hosted as websites. Each lesson represents between a half day to two days of instruction and contains several episodes, which are written as 'kramdown'-flavored 'markdown' documents and converted to HTML using the 'Jekyll' static website generator.

 ## :::::::::::::::::::::::::::::::::::::::::::::::: ##  ## ::::::::::::::::::::::::::::::::::::: objectives ##  ## - Explain how to use markdown with the new lesson template ## - Demonstrate how to include pieces of code, figures, and nested challenge blocks ##  ## :::::::::::::::::::::::::::::::::::::::::::::::: ##  ## ## Introduction ##  ## This is the new Carpentries template. It is written in [RMarkdown][r-markdown], ## which is a variant of Markdown that allows you to render code inside the ## lesson. Please refer to the [lesson ## example](https://carpentries.github.io/lesson-example) for full documentation. ##  ## What you need to know is that there are three block quotes required for a valid ## Carpentries lesson template: ##  ## 1. `questions` are displayed at the beginning of the episode to prime the ##   learner for the content. ## 2. `objectives` are the learning objectives for an episode displayed with ##   the questions. ## 3. `keypoints` are displayed at the end of the episode to reinforce the ##   objectives. ##  ## ::::::::::::::::::::::::::::::::::::: challenge ##  ## ## Challenge 1: Can you do it? ##  ## What is the output of this command? ##  ## ```{r, eval=FALSE} ## paste(\"This\", \"new\", \"template\", \"looks\", \"good\") ## ``` ##  ## :::::::::::::::::::::::: solution ##  ## ## Output ##  ## ```{r, echo=FALSE} ## paste(\"This\", \"new\", \"template\", \"looks\", \"good\") ## ``` ##  ## :::::::::::::::::::::::::::::::::: ##  ## ## Challenge 2: how do you nest solutions within challenge blocks? ##  ## :::::::::::::::::::::::: solution ##  ## You can add a line with at least three colons and a `solution` tag. ##  ## ::::::::::::::::::::::::::::::::: ## :::::::::::::::::::::::::::::::::::::::::::::::: ##  ## ## Figures ##  ## You can also include figures: ##  ## ```{r pyramid} ## pie( ##   c(Sky = 78, \"Sunny side of pyramid\" = 17, \"Shady side of pyramid\" = 5),  ##   init.angle = 315,  ##   col = c(\"deepskyblue\", \"yellow\", \"yellow3\"),  ##   border = FALSE ## ) ## ``` ##  ## ## Math ##  ## One of our episodes contains $\\LaTeX$ equations when describing how to create ## dynamic reports with {knitr}, so we now use mathjax to describe this: ##  ## `$\\alpha = \\dfrac{1}{(1 - \\beta)^2}$` becomes: $\\alpha = \\dfrac{1}{(1 - \\beta)^2}$ ##  ## Cool, right? ##  ## ::::::::::::::::::::::::::::::::::::: keypoints ##  ## - Use `.Rmd` files for lessons even if you don't need to generate any code ##

 ## :::::::::::::::::::::::::::::::::::::::::::::::: ##  ## ::::::::::::::::::::::::::::::::::::: objectives ##  ## - Explain how to use markdown with the new lesson template ## - Demonstrate how to include pieces of code, figures, and nested challenge blocks ##  ## :::::::::::::::::::::::::::::::::::::::::::::::: ##  ## ## Introduction ##  ## This is the new Carpentries template. It is written in [RMarkdown][r-markdown], ## which is a variant of Markdown that allows you to render code inside the ## lesson. Please refer to the [lesson ## example](https://carpentries.github.io/lesson-example) for full documentation. ##  ## What you need to know is that there are three block quotes required for a valid ## Carpentries lesson template: ##  ## 1. `questions` are displayed at the beginning of the episode to prime the ##   learner for the content. ## 2. `objectives` are the learning objectives for an episode displayed with ##   the questions. ## 3. `keypoints` are displayed at the end of the episode to reinforce the ##   objectives. ##  ## ::::::::::::::::::::::::::::::::::::: challenge ##  ## ## Challenge 1: Can you do it? ##  ## What is the output of this command? ##  ## ```{r, eval=FALSE} ## paste(\"This\", \"new\", \"template\", \"looks\", \"good\") ## ``` ##  ## :::::::::::::::::::::::: solution ##  ## ## Output ##  ## ```{r, echo=FALSE} ## paste(\"This\", \"new\", \"template\", \"looks\", \"good\") ## ``` ##  ## :::::::::::::::::::::::::::::::::: ##  ## ## Challenge 2: how do you nest solutions within challenge blocks? ##  ## :::::::::::::::::::::::: solution ##  ## You can add a line with at least three colons and a `solution` tag. ##  ## ::::::::::::::::::::::::::::::::: ## :::::::::::::::::::::::::::::::::::::::::::::::: ##
