+zero-blog
+=========
+
+This is the small blog engine to render and serve the blog zero-knowledge.org.
+Templates can be changed in `templates` and new posts can be created in `files/content/post`.
+
+build
+-----
+
+To build this project a simple
+
+```
+go build
+```
+
+will suffice. It will automatically pack all files into the binary.
+
+run
+---
+
+To run the project after building, call
+
+```
+./zero-blog --help
+```
+
+to get a list of all parameters.
+
+To dump the content into `tmp`, use `zero-blog --dump-files=tmp`. Or use
+`zero-blog` to start a local webserver.
+
+add new content
+---------------
+
+To add new content, place a new markdown file in `files/content`.
+
+Add a Header to the file in the following format:
+
+```
++++
+title     = "new title"
+time      = "2021-01-02T15:16:17"
+author    = "Gibheer"
+published = true
+template  = "default.html"
++++
+```
+
+Template is using `default.html` by default. If you need to use a different one, then
+set that variable.
