+
+## Setup and required packages
+
+Making API requests requires the following packages: `httr` and `jsonlite`. We can install/load these using our `loadLibraries` function (in our `woRkflow` package).
+
+```{r libraries, message = FALSE, warning = FALSE}
+library(woRkflow) # remember to build it first :-)
+woRkflow::setup() # load env.R set up the default paths etc
+
+reqLibs <- c("httr",
+             "jsonlite",
+             "knitr",
+             "tidyr",
+             "data.table", # data munching
+             "here", # here
+             "lubridate", # dates and times
+             "ggplot2", # plots
+             "bookdown" # for making reports (should also install knittr etc)
+)
+# load them
+woRkflow::loadLibraries(reqLibs)
+```
+
+## Shiny apps and documents
+
+Two types of Shiny implementation:
+
+* Shiny app - a web appliacation based on R code
+* Shiny document - an R Markdown document that can include dynamic elements by incorporating Shiny objects
+
+
+
+### Layout
+
+https://vimeo.com/rstudioinc/review/131218530/212d8a5a7a/#t=1h36m51s
+
+Using the layout function produces html(as with tags$) .
+
+Rows:
+
+e.g. `fluidRow()` creates `<div class="row"></div>`
+
+Each new row is placed beneath the previous one.
+
+Columns (12 units wide - use arguments `width` and `offset` to control size and position):
+
+e.g. `column(width = 2)` creates `<div class="col-sm-2"></div>`
+
+
+`tags$h1()` # heading text (lvl 1) - use h1 to h6
+`tags$p()`  # paragraph
+`tags$strong()`, `tags$em()` # 
+`tags$hr()` # 
+`tags$img()` # insert image  - see <https://vimeo.com/rstudioinc/review/131218530/212d8a5a7a/#t=1h45m30s>
+
+## Deployment
+
+To deploy both apps and documents. Same process?
+
+See bookdown site for deploying Shiny documents.
+<https://bookdown.org/yihui/rmarkdown/shiny-deploy.html>
+
+### shinyapps.io
+
+Using shinyapps.io
+
+https://vimeo.com/rstudioinc/review/131218530/212d8a5a7a/#t=0h30m45s
+
+For example:
+
+```{r}
+rsconnect::deployApp('/Users/twr1m15/SotonGitLab/woRkflow/howTo/shiny/App', appName = "gridforecast",appTitle = "GB Grid Electricity Carbon Intensity Forecast Visualisation")
+```
+
+### RStudio connect
