+1. Put your library somewhere public in git.
+2. Edit [repos.json](https://github.com/OpenModelica/OMLibraries/blob/master/repos.json) and add the URL to your library with the gittag or hash and branch name.
 
+    **Example for a public GitHub repository using a git tag:**
+    ```json
+    [...]
+    {
+        "core": true,                               // Is your library a core library (true) or another library (false)
+        "dest": "LibraryName",                      // The name of your library
+        "options": {
+            "gitbranch": "master",                  // Git branch (optional)
+            "gittag": "v1.0.0",                     // Git tag pointing to commit to be used
+            "license": "bsd3"                       // Under what license is your library published (optional)
+        },
+        "rev": "v1.0.0",                            // Version of your library you tagged
+        "url": "https://github.com/UserName/LibraryName/.git"        // URL of your GitHub repository
+    },
+    [...]
+    ```
+
+    **Example for a public GitHub repository using a branch and commit hash:**
+    ```json
+    [...]
+    {
+        "core": true,                               // Is your library a core library (true) or another library (false)
+        "dest": "LibraryName",                      // The name of your library
+        "options": {
+            "gitbranch": "v1.0.0-maintenance",      // Git branch
+            "license": "bsd3"                       // Under what license is your library published (optional)
+        },
+        "rev": "802e7d85e35e14asdg53dsg1sdd6911804382f29",           // Version of your library you tagged
+        "url": "https://github.com/UserName/LibraryName/.git"        // URL of your GitHub repository
+    },
+    [...]
+    ```
+    Note that JSON doesn't allow comments, so delete all comments from the above examples.
