## Description

<strong>CP Sync</strong> watches your submissions on <strong>Codeforces, CodeChef, LeetCode, HackerRank, AtCoder, vJudge, GeeksforGeeks, CSES, NeetCode etc.</strong> When a solution is accepted, the extension fetches your source code and commits it to a GitHub repo, organized by platform, difficulty, and contest.

You don’t need to copy‑paste or remember to update your repo at the end of a session. The extension handles everything in the background.

<strong>Features</strong>
<ul><li>Auto‑detects Accepted verdicts on nine major judges.</li><li>Manual Push with Autofill- for judges not yet supported or when detection misses a submission. The autofill reads problem name, link, and difficulty from your current tab.</li><li>Duplicate prevention- identical solutions are not re‑committed.</li><li>Streak tracking and push history- see your daily streak and a log of every commit.</li><li>Automatic retry- transient GitHub errors are retried with exponential backoff.</li><li>Fully customisable- commit message templates, language handling, and folder structure.</li></ul>
<strong>Supported platforms:</strong>
Codeforces, CodeChef, LeetCode, HackerRank, AtCoder, vJudge, GeeksforGeeks, CSES, NeetCode and others using manual push.

<strong>Setup</strong>
<ol><li>Install the extension.</li><li>On GitHub, create a <strong>fine-grained Personal Access Token</strong> with <strong>Contents: Read and write</strong> permission and grant it access to the repository where you want to store your solutions.</li><li>Open CP Sync and enter:</li></ol>
GitHub Username/Organization:<strong> the owner of the repository
   Repository Name:</strong> the repository name only, without <code>.git</code>
   Personal Access Token:<strong> the token created in Step 2
   Branch:</strong> the branch where you want your solutions committed
4. Click <strong>Test Connection</strong> to verify that CP Sync can access the repository.
5. Select the competitive programming platforms you want to sync and click <strong>Save Settings</strong>.

Once connected, solve problems normally. When CP Sync detects an <strong>Accepted</strong> submission, it automatically pushes the solution to your configured GitHub repository.
