This is the source for the community website of the tpm2-software namespace on
GitHub. It uses github pages (with Jekyl).

# Building (locally)

Note that github.io will automatically build this page, but you should probably
test it locally first.

## Prerequisits

```
$ sudo gem install bundler
$ sudo bunde install #This needs to happen inside the directory
```

## Build

```
$ bundle exec jekyll serve --incremental
```
