 # dela (pun интедед) - daily events list application, aka web TODO list
 
+## About
+
+dela is a web TODO list application which can be hosted on your server and accessed via browser. Current capabilities include: 
+
+- Password protected account system
+- TODO creation
+- TODO completion
+
+## Build
+
+```
+make
+```
+
+or manually compile with `go build` inside the `src` directory, move the binary and put it alongside `pages`, `scripts` and `static` (although the path to the contents can be specified via configuration file).
+
+```
+make portable
+```
+
+will create a `dela.zip` archive with all the content directories and the binary which are to be freely transported to other machines (of the same OS and architecture, obviously) 
+
+## Use
+
+After the first run a configuration file will be put alongside the executable, upon the second launch server will start and the service will be accessible on the specified port.
