+# Feature: Build Skills tab
+The second tab of the addon will follow these [designs](./build_skills_tab_design.png).
+
+## Acceptance Criteria
+- This screen should show the same skills we use in the main screen, which come from the TRP profile
+- The skills should be sorted by level
+- The skill list should be scrollable, with the "Save" button pinned/sticky to the bottom
+## Editing skills
+- The user should be able to edit the name, level, and numerical score of each skill
+- Edits should not be saved until the user explicitly clicks the "Save" button
+### Skill Level and Value
+- When a skill level is selected, the numerical score dropdown should update to only allow values within the skill level
+  - Inept: 0
+  - Novice: 1-5
+  - Adept: 6-10
+  - Expert: 11-19
+  - Master: 20
+### Deleting skills
+- Clicking the "Delete" button should remove the skill from the list
+### Adding Skills
+- Clicking the "Add a Row" button should add a new skill row to the list
+- Default values for the new skill should be:
+  - Name: Skillname
+  - Level: Novice
+  - Value: 1
+### Saving Skills
+- When clicking the "Save" button:
+  - Newly added skills should be added to the TRP profile
+  - Existing skills should be updated in the TRP profile
+  - Skills that were deleted should also be removed from the TRP profile
+- Icons should not be changed
