Run this app from the terminal, [passing its directory to LÖVE](https://love2d.org/wiki/Getting_Started#Running_Games).
pothi.love will print the path where it expects to find articles. Quit, create
a folder called `data/` under this path, put text files there. Restart.

Open the app. Initially you'll see a series of two errors. The first error
looks like this:
  ```
  Error: no directory /home/akkartik/.local/share/love/pothi/data found. Please store articles to browse there before opening this app.
  ```

For example, I created the `data/` dir using these commands on my machine:

Put any articles you'd like to browse at this location. (You can copy it from
the error to the clipboard by pressing `ctrl+c`.) Quit and restart.

Now you'll see the second error:

  cd ~/.local/share/love/pothi

  Sorry, I am not permitted to create directories (folders). Please create directory /home/akkartik/.local/share/love/pothi/data/comments for storing comments in.
  ```
Create the sub-directory mentioned here. (Again, you can copy the error
message to the clipboard by pressing `ctrl+c`.) Quit and restart.
Now the app will open to a list of files. Click on any filename to read it and
leave comments on it. The comments will live on your computer. Share them with
others by any means of your choice.
It's not the cleanest onboarding in the world. As a concrete example, on my
machine I ran the following commands in a terminal window to get past both
errors:
  ```shell
  cd /home/akkartik/.local/share/love/pothi

  mkdir data/comments

## Terminal invocation
You can run this app from the terminal [just like any other LÖVE app](https://love2d.org/wiki/Getting_Started#Running_Games).
This ability is particularly useful if you would like to maintain multiple
directories of articles and switch between them.

And now I can see the files when I restart:

To load any other directories besides `data/`, run the app from a terminal and
provide the name of the directory in the command.

As a concrete example, suppose you've set things up so you can run the app
from the terminal by running:
  ```shell
  love pothi.love

  love ~/pothi

Further suppose you loaded some articles as follows:
  ```shell
  cd ~/.local/share/love/pothi
  git clone http://canonical.org/~kragen/sw/pavnotes2.git   # no directory name provided
  # articles now saved to a directory called pavnotes2
  mkdir pavnotes2/comments

To now browse these articles, you'd run:

The app will open to a directory view by default (though there's no scrolling
or filtering yet, sorry..). Click on any filename to read it.

  ```shell
  love pothi.love pavnotes2
  ```

end

end
