 ## Migration from 2.x 
 
-:warning: You **MUST** update to latest version of 2.x and **run your bot at least once** before switching over to v3 
+:warning: If you're already hosting NadekoBot, You **MUST** update to latest version of 2.x and **run your bot at least once** before switching over to v3 
 
-## Changes
-
-- Code cleanup
-  - Command attributes cleaned up
-    - Removed dummy Remarks and Usages attributes 
-    - They were unused for a few patches but stayed in the code to avoid big git diffs
-  - All database migrations and data (json file) migrations have been removed
-    - As updating to the latest 2.x version before switching over to v3 is mandated (or fresh v3install), that means all migration code has ran and it can be safely removed 
-  - There are 2 projects: NadekoBot and NadekoBot.Coordinator
-    - You can directly run NadekoBot as the regular bot with one shard
-    - Run NadekoBot.Coordinator if you want more control over your shards and a grpc api for coordinator with which you can start, restart, kill and see status of shards
-- credentials.json moved to `creds.yml`
-  - example is in `creds_example.yml`
-  - most of the credentials from 2.x will be automatically migrated
-- Guides
-  - Now instruct users to set build output to nadekobot/output instead of running from nadekobot/src/NadekoBot/bin/release/net5
-  - todo: Reworked from source installation (linux/windows) guide <todo link>
-  - todo: Added docker support, installation guide at <todo link>
