-Development
-===================================================================================================
-As a solo-project, I am not only the **developer**, but also the **manager**. 
-Therefore there is a need, if this project is to succeed, to have a development plan. 
-
-Such a plan should:
-
-- Define a way to **distribute work** (across time, since there's only 1 developer).
-- Define what is a **unit of work** (cycles).
-- Provide a way to **track productivity**, which helps projecting the future and **detecting patterns** early on.
-- Provide a **pipeline** for the work to go through and **minimize ambiguity**.
-
-These are the **management** aspects of the project, which help the development goals to be more **pragmatic**
----by pulling my mind out of its **engineering dreamland**, and make it focus on the **broader picture**.
-
-Cycle
----------------------------------------------------------------------------------------------------
-A cycle is one **step** in development, one cycle = one ticket, and it consists of 4 stages:
-
-1 - Make it known
-    - Write the commit message.
-        - This limits the **scope of changes** and gives you a very specific **goal** to work towards.
-        - If something outside of this scope really bothers you, fix and stash for a future cycle.
-        - Make a ticket if stash-fix is implausible ---**DO NOT** write **todo** comments.
-        - The message should follow the project's **commit message specifications**.
-
-    - Make a ticket.
-        - Version control (git) is a **development-tool**, not a **management-tool**.
-        - Provide a very brief description ---This may be used in the commit message's body.
-
-2 - Make it work
-    - Write high-level tests that confirms the cycle's requirements are met.
-        - That is, specify requirements in a programming language instead of English.
-        - You're done when all the tests pass.
-        - Preferably write the tests first, but it's okay to start with the interface.
-        - Tests may not be necessary depending on the requirements and commit type.
-
-    - "Make it work" doesn't mean liberally producing shit code, you should:
-        - Follow project's **conventions**.
-        - Follow **best practices** and **proven swe principles**.
-        - Enable **warnings as errors**.
-        - Enable **static analysis**.
-        - Don't break any pre-existing-tests.
-        - Have the over-all picture in mind.
-
-3 - Make it right
-    - Test driven refactoring
-        - Now you have a better picture of how things relate and work.
-        - Switch to a TDD-style development to do the refactoring while following swe best-practices and proven-principles.
-
-4 - Make it fast
-    - This is an engine, at the end of the day, **performance** is king.
-    - Get a performance and/or memory profile and try to alleviate the bottlenecks.
-    - Avoid premature optimizations, be certain what you change has performance benefits.
-
-
-Sprint
----------------------------------------------------------------------------------------------------
-A sprint is the collection of all the finished cycles in one week.
-It's meant to provide insight on development speed and help projecting the future.
-
-
-Commit Message Specification
----------------------------------------------------------------------------------------------------
-The project follows the `Conventional Commits Specification <https://www.conventionalcommits.org/en/v1.0.0-beta.4>`_.
-
-.. code-block:: md
-
-    <type>[optional scope]: <description>
-
-    [optional body]
-
-    [optional footer]
-
-With the following commit types:
-
-- feat
-    - For adding a new feature.
-    - Causes a **minor** bump in version.
-
-- fix
-    - For changes that fix one or more bug.
-    - Causes a **patch** bump in version.
-
-- refactor
-    - For non feat/fix changes that improve the implementation and/or the interface.
-    - Causes a **patch** bump in version.
-
-- perf
-    - For changes that (hopefully) improve the performance.
-    - Causes a **patch** bump in version.
-
-- build
-    - For changes that affect the build system or external dependencies.
-    - Causes a **patch** bump in version.
-
-- asset
-    - For changes to the files under the ``/data`` directory.
-    - Causes a **patch** bump in version.
-
-- test
-    - For adding missing tests or correcting the existing tests.
-    - Does not affect the version.
-
-- chore
-    - For releases, .gitignore changes, deleting unused files, etc.
-    - Does not affect the version.
-
-- ci
-    - For changes to our CI configuration files and scripts, including files under ``/tools/ci``.
-    - Does not affect the version.
-
-- docs
-    - For changes to the documentations.
-    - Does not affect the version.
-
-Semantic Versioning
----------------------------------------------------------------------------------------------------
-Coupled with conventional commit style messages, we can automajically version the project following
-the **Semantic Versioning 2.0.0** specifications.
-
-The full version identifier consits of a version core (major.minor.patch) + label + hexsha of the commit.
-Using the following format:
-
-
-.. code-block:: md
-
-    <major>.<minor>.<patch>-<label>+<short_hexsha>
-
-    eg.
-    0.8.1-kitten+ea898 
-    0.5.0-kitten+01d85
-    1.5.0-akasha+7de53
-
-    kitten refers to all pre-release (1.0.0) versions
-
-
-The shortened hexsha of a commit is obtained by:
-``git rev-parse --short=5 <commit_hexsha>``
