+# Markdown Benchmark; CSV+text version
+
+This is a baseline benchmark for tracking CSV plaintext performance in the Gabe project.
+
+This will produce the same site as `gabe-markdown` without using any markdown. It also generates one giant csv file containing all the data, rather than an individual file per page.
+
+The site can generate an arbitrary amount of super simple pages. Each page has a small header, a quote, and two small paragraphs of random text. No images, because that's a fixed cost we're not interested in.
+
+## Install
+
+Run `yarn` or `npm install`
+
+## Usage
+
+You can start a benchmark run like this:
+
+```shell
+N=1000 M=2 yarn bench
+```
+
+- `N=1000`: instructs the run to build a site of 1000 pages
+- `M=2`: instructs nodejs to use up to 2gb of memory for its long term storage
+- Deletes generates files from previous run
+- Generates a new `gendata.csv` file containing `N` rows, each row being one page with pseudo-random content
+- Runs `gatsby clean`
+- Runs `gatsby build`
+
+The default `yarn bench` will build 512 pages with 1gb memory.
