+Both `publish` and `development-publish` branches are protected. Changes cannot be pushed into them directly.
+They require approved PR.
 
 A webhook has been installed on the publish branch to
 https://publish.d20i0wkqbblkur.amplifyapp.com/
 https://github.com/pycom/pycom-documentation/tree/master
+    
+### Updating documentation pages (no development firmware API changes)
+Use this workflow if you want to update documentation pages
+(you are not updating pages with new development firmware API).
+
+    $ git checkout publish
+    $ git pull
+    $ git checkout -b my-docs-update
+    
+After you push your changes to your branch, go to GitHub and create two pull requests.
+So your branch is merged both to `publish` and `development-publish` branch.
+
+After a moment both https://docs.pycom.io and https://development.pycom.io will be updated.    
+

+
+### Adding development firmware API changes
+This workflow will be probably done by someone from Pycom firmware development team.
+In this case, Pycom development docs https://development.pycom.io/ needs to be updated with API changes from development firmware.
+
+Note: we are running https://docs.pycom.io and https://development.pycom.io
+When a user clicks on development dropdown on any firmware API change, he/she will be redirected to https://development.pycom.io
+
+    $ git checkout development-publish
+    $ git pull
+    $ git checkout -b my-fw-api-update
+    
+After you push your changes to your branch,
+go to GitHub and create a pull with **development-publish** branch as a base branch.    
+
+![fw api changes](static/github/devFwChanges.jpg)
+
+### Adding changes from "publish" branch to "development-publish" branch
+In this case, you want to sync "development" version of docs with the "stable" docs.
+
+    $ git checkout development-publish
+    $ git pull
+    $ git checkout publish
+    $ git pull
+    $ git checkout -b my-sync-branch
+    $ git merge development-publish
+     
+After you push your changes to your branch,
+go to GitHub and create a pull with **development-publish** branch as a base branch.    
+
+![alt text](static/github/fromPublishToDevelopmentPublish.jpg)
+
+### Adding changes from "development-publish" to "publish" (when development FW API becomes stable FW API)
+In this case, you want to add changes from development firmware API to stable docs.
+
+    $ git checkout publish
+    $ git pull
+    $ git checkout development-publish
+    $ git pull
+    $ git checkout -b my-sync-branch
+    $ git merge development-publish
+
+After you push your changes to your branch,
+go to GitHub and create a pull with **publish** branch as a base branch.
