+# Gn-Markdown
+
+Gn-Markdown is an API endpoint to edit, parse, and commit markdown files for gn-docs.
+
+## How to Test the APIs
+
+1. **Navigate to the Web Directory and Start the Server**
+
+Running the web server is documented in [guix script](./web/.guix-shell).
+
+```
+curl http://127.0.0.1:8091/version
+"4.0.0"
+```
+
+```sh
+cd web
+export CURRENT_REPO_PATH=<path-to-git-repo-with-files>
+export CGIT_REPO_PATH=<path-to-git-bare-repo>
+. .guix-shell -- guile -L .. --listen=1970 -e main ./webserver.scm 8091
+```
+
+
+
+2. **Test Endpoints**
+
+The main endpoints provided are `/edit` and `/commit`. More endpoints may be added in the future.
+
+## Edit (GET)
+
+This is a GET request to retrieve a file's details. Make sure you pass a valid file_path as search_query (the path should be relative to the repo)
+
+**Request Example:**
+
+```bash
+
+curl -G -d "file_path=test.md"  localhost:8091/edit
+
+```
+
+**Expected Success Response:**
+
+```json
+{
+"file_path": "test.md",
+"content": "Test for new user\n test 2 for line\n test 3 for new line\n ## real markdown two test\n",
+"hash": "ecd96f27c45301279150fbda411544687db1aa45"
+}
+```
+
+**Expected Error Response (Status 400):**
+
+```json
+{
+"error": <error_type>,
+"msg": <error_reason>
+}
+```
+
+## Commit (POST)
+
+This is a POST request to commit changes to a file.
+
+**Request URL:**
+
+```bash
+
+curl -X POST http://127.0.0.1:8091/commit \
+-H 'Content-Type: application/json' \
+-d '{
+"content": "make test commit",
+"filename": "test.md",
+"email": "test@gmail.com",
+"username": "test",
+"commit_message": "init commit",
+"prev_commit": "7cbfc40d98b49a64e98e7cd562f373053d0325bd"
+}'
+
+```
+
+
+
+**Expected Response for success:**
+
+```json
+{
+"status": "201",
+"message": "Committed file successfully",
+"content": "Test for new user\n test 2 for line\n test 3 for new line\n ## real markdown two test\n",
+"commit_sha": "47df3b7f13a935d50cc8b40e98ca9e513cba104c",
+"commit_message": "commit by genetics"
+}
+
+```
+
+**If No Changes to File:**
+
+```json
+{
+"status": "200",
+"message": "Nothing to commit, working tree clean",
+"commit_sha": "ecd96f27c45301279150fbda411544687db1aa45"
+}
+```
+
+**Expected Error Response:**
+
+```json
+{
+"error": "system-error",
+"msg": "Commits do not match. Please pull in the latest changes for the current commit *ecd96f27c45301279150fbda411544687db1aa45* and previous commits."
+}
+```
+
+## Notes
+
+This is meant to be used as api endpoint only to edit any local repo; Clients are expected to handle other service e.g User Interface, authentication
