Mike,

Looks good as a starting point!

I do have a few questions on this sentence:  "Specification text changes are held within the affected source repository, using the GitHub flavor of markdown, in a file (or split across several files) with .md suffix."

- For TianoCore, is the "affected source repository" this sentence is referring to edk2-staging, or edk2?

- If the proposed specification and associated code starts in a branch in edk2-staging respiratory, when does it get accepted into edk2/edk2-platforms? Is it when the proposed specification change reaches a certain status (such as "accepted by industry standard forum"), or when the formal specification (with that proposed change) is published by the UEFI Forum ?


Samer,

While in the “code 1st state” there are BZ# prefixes to types and globals. So when the code ends up in the specification the “code 1st” branch is going to need to get cleaned up for naming, and I assume we could remove the MD files before a patch is submitted to the edk2. 

We made extra work for ourselves, but we wanted it to be clear what was work in progress. 

Thanks,

Andrew Fish 

- Any guidance on the specification text md file(s) names (and location) within the repository?

- If the change includes some graphics, is there any guidance on inclusion of the graphics files in the repository?

Thanks,

Based on the following RFC:

   https://edk2.groups.io/g/rfc/message/258

Additional updates:
* Add examples of all specifications currently maintained by
 the UEFI Forums.
* Added specification change template using a CC-BY-4.0 license.
* Add source code example for an enum value
* Minor grammar updates to change from an RFC proposal to an
 active process.

+The EDK II Code First Process is a process by which new features can
+be added to UEFI Forum specifications after first having been
+designed and prototyped in the open.
+
+This process lets changes and the development of new features happen
+in the open, without violating the UEFI forum bylaws which prevent
+publication of code for in-draft features/changes.
+
+The process does not in fact change the UEFI bylaws - the change is
+that the development (of both specification and code) happens in the
+open. The resulting specification update is then submitted to the
+appropriate working group as an Engineering Change Request (ECR), and
+voted on. For the UEFI Forum, this is a change in workflow, not a change
in process.
+
+ECRs are tracked in a UEFI Forum Mantis instance, access restricted
+to UEFI Forum Members. TianoCore enables this new process by
+providing areas on [TianoCore
+Bugzilla](https://bugzilla.tianocore.org) to track both specification
+updates and reference implementations and new repositories under
[TianoCore GitHub](https://github.com/tianocore) dedicated to hold "code
first".
+
+# TianoCore Bugzilla
+
+[TianoCore Bugzilla](bugzilla.tianocore.org) has a product categories
+for
+  * ACPI Specification
+  * UEFI Shell Specification
+  * UEFI Platform Initialization Distribution Packaging Specification
+  * UEFI Platform Initialization Specification Specification
+  * UEFI Specification
+
+Each product category has separate components for
+  * Specification
+  * Reference implementation
+
+# TianoCore GitHub
+
+Reference implementations targeting the EDK II open source project
+are held in branches in the
+[edk2-staging](https://github.com/tianocore/edk2-staging)
+repository.
+
+Additional repositories for implementing reference features in
+additional open source projects can be added in the future, as required.
+
+Specification text changes are held within the affected source
+repository, using the GitHub flavor of markdown, in a file (or split
+across several files) with .md suffix.  Multiple files are required
+if changes impact multiple specifications or if the specification is
+large and is easier to maintain if the changes are split across multiple
files.
+
+* NOTE: This one may break down where we have a specification change
+affecting
+  multiple specifications, but at that point we can track it with
+multiple
+  TianoCore Bugzilla entries.
+
+## Specification Text Template
+
+The following is a template of specification text changes using the
+GitHub flavor of markdown.  The title and complete description of the
+specification changes must be provided in the specification text
+along with the name and version of the specification the change
+applies.  The `Status` of the specification change always starts in
+the `Draft` state and is updated based on feedback from the industry
+standard forums.  The contents of the specification text are required
+to use the [Creative Commons Attribution 4.0
+International](https://spdx.org/licenses/CC-BY-4.0.html)
+license using a `SPDX-License-Identifier` statement.
+
+```
+# Title: [Must be Filled In]
+
+# Status: [Status]
+
+[Status] must be one of the following:
+* Draft
+* Submitted to industry standard forum
+* Accepted by industry standard forum
+* Accepted by industry standard forum with modifications
+* Rejected by industry standard forum
+
+# Document: [Title and Version]
+
+Here are some examples of [Title and Version]:
+* UEFI Specification Version 2.8
+* ACPI Specification Version 6.3
+* UEFI Shell Specification Version 2.2
+* UEFI Platform Initialization Specification Version 1.7
+* UEFI Platform Initialization Distribution Packaging Specification
+Version 1.1

+
+# Summary of the change
+
+Required Section
+
+# Benefits of the change
+
+Required Section
+
+# Impact of the change
+
+Required Section
+
+# Detailed description of the change [normative updates]
+
+Required Section
+
+# Special Instructions
+
+Optional Section
+```
+
+# Intended workflow
+
+The entity initiating a specification change enters a Bugzilla in the
+appropriate area of [TianoCore Bugzilla](bugzilla.tianocore.org).
+This entry contains the outline of the change, and the full initial draft
text is attached.
+
+If multiple specification updates are interdependent, especially if
+between different specifications, then multiple Bugzilla entries should be
created.
+These Bugzilla entries *must* be linked together with dependencies.
+
+After the Bugzillas have been created, new branches should be created
+in the relevant repositories for each Bugzilla.  The branch names
+must use the following format where #### is the Bugzilla ID and
+<Brief Description> is an optional description of the change.
+
+    BZ####-<Brief Description>
+
+If multiple Bugzilla entries must coexist on a single branch, one of
+them is designated the _top-level_, with dependencies properly
+tracked. That Bugzilla is be the one naming the branch.
+
+# Source Code
+
+In order to ensure draft code does not accidentally leak into
+production use, and to signify when the changeover from draft to
+final happens, *all* new or modified[1] identifiers must be prefixed with
the relevant BZ#### identifiers.
+
+* [1] Modified in a non-backwards-compatible way. If, for example, a
statically
+      sized array is grown - this does not need to be prefixed. But a tag in a
+      comment would be *highly* recommended.
+
+## File names
+
+New public header files require the prefix (i.e.
`Bz1234MyNewProtocol.h`).
+Private header files do not need the prefix.
+
+## Contents
+
+The tagging must follow the coding style used by each affected code
base.
+Examples:
+
+| Released in spec | Draft version in tree | Comment |
+| ---              | ---                   | ---     |
+| `FunctionName`   | `Bz1234FunctionName`  |         |
+| `HEADER_MACRO`   | `BZ1234_HEADER_MACRO` |         |
+
+For data structures or enums, any new or non-backwards-compatible
+structs or fields require a prefix. As above, growing an existing
+array in an existing struct requires no prefix.
+
+| Released in spec      | Draft version in tree | Comment               |
+| ---                   | ---                   | ---                   |
+| `typedef SOME_STRUCT` | `BZ1234_SOME_STRUCT`  | Typedef only [2]
|
+| `StructField`         | `Bz1234StructField`   | In existing struct[3] |
+| `typedef SOME_ENUM`   | `BZ1234_SOME_ENUM`    | Typedef only [2]
|
+| `EnumValue`           | `BzEnumValue`         | In existing enum[3]   |
+
+* [2] If the struct or enum definition is separate from the typedef in the
public
+      header, the definition does not need the prefix.
+* [3] Individual fields in newly added struct or enum do not need prefix,
the
+      struct or enum already carried the prefix.
+
+Variable prefixes indicating global scope ('g' or 'm') go before the BZ
prefix.
+
+| Released in spec | Draft version in tree | Comment |
+| ---              | ---                   | ---     |
+| `gSomeGuid`      | `gBz1234SomeGuid`     |         |
+
+Local identifiers, including module-global ones (m-prefixed) do not
+require a BZ prefix.
