+
+### Description
+
+The Request-for-Proposal (RFP) strategy allows the pool owner to facilitate bids for a specific scope of work. As opposed to other strategies where there are multiple recipients of a pool, in this strategy only one applicant is selected to receive the funds.
+
+## New Variables
+```javascript
+
+struct Application {
+    MetaPtr metaPtr;
+    address identityId;
+    address recipientAddress;
+    ApplicationStatus status;
+}
+
+// stores mapping from identityId -> Application
+mapping (address => Application[]) public applications;
+
+```
+
+## New Functions
+
+Functions around actual functionality
+
+```javascript
+
+function reviewApplications(bytes[] memory _data) external {
+    // decode data to get list of 
+    //  - identityId
+    //  - index of application (to know which application)
+    //  - status
+
+    // update application status in applications mapping
+}
+```
+
+
+## Open Questions
+- How do we want to handle single-choice vs committee vote? Some versions may just want to have one wallet be able to select / chose an application to receive the allocation. Other versions may want to let a small group vote to decide who receives the funds.
