 # Owl Blogs
 
-A simple web server for blogs generated from Markdown files
+Owl-blogs is a blogging software focused on simplicity with IndieWeb and Fediverse support.
 
-## Repository
+# Usage
 
-A repository holds all data for a web server. It contains multiple users.
+## Run
 
-## User
+To run the web server use the command:
-
-A user has a collection of posts.
-Each directory in the `/users/` directory of a repository is considered a user.
-
-### User Directory structure
 
 ```
-<user-name>/
+owl web
-  \- public/
-       \- <post-name>
-            \- index.md
-                -- This will be rendered as the blog post.
-                -- Must be present for the blog post to be valid.
-                -- All other folders will be ignored
-            \- status.yml
-                -- Used to track various process status related to the post, 
-                -- such as if a webmention was sent.
-            \- media/
-                -- Contains all media files used in the blog post.
-                -- All files in this folder will be publicly available
-            \- webmention/
-               \- <hash>.yml
-                    -- Contains data for a received webmention
-  \- meta/
-       \- base.html
-            -- The template used to render all sites
-       \- VERSION
-            -- Contains the version string.
-            -- Used to determine compatibility in the future
-  \- config.yml
-        -- Contains settings global to the user.
-        -- For example: page title and style options
 ```
 
-### Post
+The blog will run on port 3000 (http://localhost:3000)
 
-Posts are Markdown files with a mandatory metadata head.
+To create a new account:
-
-- The `title` will be added to the web page and does not have to be reapeated in the body. It will be used in any lists of posts.
-- `aliases` are optional. They are used as permanent redirects to the actual blog page.
 
 ```

+owl new-author -u <name> -p <password>

+To retrieve a list of all commands run:
-#### status.yml
 
 ```

-       supported: true
-       scanned_at: 2021-08-13T17:07:00Z
-       last_sent_at: 2021-08-13T17:07:00Z
 ```
+
+# Development
+
+## Build
+
+```
+CGO_ENABLED=1 go build -o owl ./cmd/owl
+```
+
+For development with live reload use `air` ([has to be install first](https://github.com/cosmtrek/air))
+
+## Tests
+
+The project has two test suites; "unit tests" written in go and "end-to-end tests" written in python.
+
+### Unit Tests
+
+```
+go test ./...
+```
+
+### End-to-End tests
+
+- Start the docker compose setup in the `e2e_tests` directory.
+- Install the python dependencies into a virtualenv
+```
+cd e2e_tests
+python3 -m venv venv
+. venv/bin/activate
+pip install -r requirements.txt
+```
+- Run the e2e_tests with `pytest`
